Foot and Ankle Curricular Guidelines in Entry-Level Physical Therapist Education: How Are We Doing?

INTRODUCTION

The Foot and Ankle Curricular Guidelines for Physical Therapist Professional Degree Programs (FACG) provided recommendations regarding essential entry-level content and skills. Eight years later, the extent of its implementation is unknown. This study characterizes entry-level Doctor of Physical Therapy (DPT) programs' foot and ankle curriculum with reference to the FACG.

REVIEW OF LITERATURE

Curricular guidelines offer recommendations to professional degree programs striving for excellence. Review and revisions of guidelines are important to keep pace with and reflect evolving evidence and practice.

SUBJECTS

One faculty member from 116 of 250 DPT programs participated (46.6% response rate). Participants were an average of 50.8 years old and taught a mean of 14.5 years.

METHODS

A cross-sectional 25-item online survey assessed foot and ankle contact hours, coverage of FACG recommended content, coverage of surgical procedures, and the use of FACG for curricular assessment, modification, and development.

RESULTS

Foot and ankle content was covered in physical therapy curriculum for a mean of 48.2 hours (range 12-120 hours). Eleven of the 25 recommended diagnoses, 29 of the 49 examination skills, 6 of the 7 intervention skills, and 3 of the 14 surgical procedures were covered by most (≥90%) of the programs. Reported use of FACG for curricular processes averaged 50.1-51.5 (0-100 numerical scale).

DISCUSSION AND CONCLUSIONS

Across a wide range of contact hours, coverage of FACG recommended content was approximately 57% (46/81 recommended elements in ≥90% of programs). Although not specifically recommended by FACG, surgical procedures were less commonly covered by programs. Study findings question FACG implementation and may reflect differences across programs in depth and breadth of content. Identified curricular gaps may warrant addressing in future guidelines.

The Effectiveness of Acupuncture on Myofascial Trigger Points Versus Traditional Chinese Medicine Acupoints for Treating Plantar Fasciitis With Low Back Pain: A Study Protocol for a Randomised Clinical Trial

Background

Plantar fasciitis is a common cause of heel pain, often associated with a higher rate of low back pain. This increased disability rate in low back pain may be correlated with reduced foot and ankle function. While both acupuncture and trigger point dry needling have been reported as potentially effective treatments for plantar fasciitis, the quality of evidence is currently low. Acupuncture at trigger points might be a promising treatment for plantar fasciitis, though there is a lack of evidence supporting its effectiveness. This trial aims to compare the effectiveness of acupuncture at trigger points versus Traditional Chinese Medicine (TCM) acupoints in the treatment of participants with plantar fasciitis and low back pain.

Methods

The trial will be a single-centre, parallel two-group, randomised controlled trial with 62 participants allocated in a 1:1 ratio to either the trigger point group or the TCM acupoint group. Patients with plantar fasciitis and low back pain will be enrolled in this trial. Eligible participants will receive acupuncture for 30 minutes per session over 8 total sessions, with a 12-week follow-up period. The primary outcome measure will be the change from baseline in the worst first-step pain intensity in the morning after treatment. Secondary outcomes include changes from baseline in foot and low back pain, foot and low back function, plantar fascia thickness, and participants' self-reported global improvement. Statistical analysis will be conducted using a two-sided test with a significance level of 0.05 and 95% confidence intervals.

Clinical Trial Registration

This trial has been registered at the Chinese Clinical Trial Registry. Registration number: ChiCTR2300067552. Registration date: 1 January 2023.

Revised minimal important difference values for the visual analogue scale and Foot Health Status Questionnaire when used for plantar heel pain

BACKGROUND

The visual analogue scale (VAS) and the Foot Health Status Questionnaire (FHSQ) are patient-reported outcome measures that are frequently used to evaluate the management of plantar heel pain. This study aimed to re-calculate (i.e. revise) the minimal important differences (MIDs) of the VAS and the FHSQ when used for plantar heel pain to enhance the validity and precision of previous estimates.

METHODS

This study used an anchor-based method to calculate MIDs and incorporated best-practice analyses to ensure credibility of the estimates. Data from 369 participants previously recruited from the community into four randomised controlled trials that evaluated interventions for plantar heel pain were used. VAS and FHSQ data from these participants at baseline and follow-up were pooled to calculate the MIDs (95% confidence intervals). A 15-point global rating of change Likert scale was used at follow-up as the transition scale, which was anchored to baseline. For the VAS, MIDs for two distinct types of pain were calculated: average pain and first-step pain. For the FHSQ, MIDs for two domains were calculated: foot pain and foot function.

RESULTS

The revised MIDs for the 100 mm VAS were -8.5 mm (95% CI: -12.2 to -4.7) for average pain and -19.2 mm (95% CI: -24.7 to -13.8) for first-step pain, which represent improvements in pain. The MIDs for the FHSQ were 12.4 points (95% CI: 6.9 to 18.0) for foot pain and 6.4 points (95% CI: 0.9 to 11.9) for foot function, which represent improvements in foot health status.

CONCLUSIONS

The revised MIDs from this study for the VAS and the FHSQ when used for plantar heel pain have enhanced validity and precision compared to previous estimates. This is important for clinicians and researchers as it provides a better understanding of how much improvement is required by an individual before an important change is experienced. The revised MIDs will also assist researchers with prospective sample size calculations, so future clinical trials are appropriately powered from a statistical standpoint.

The association of demographic, psychological, social and activity factors with foot health in people with plantar heel pain

BACKGROUND

Plantar Heel Pain (PHP) can be a debilitating musculoskeletal condition from which only 50% recover within a year due to poor understanding of the mechanisms explaining severity and predicting outcomes specific to PHP.

OBJECTIVE

To explore associations between biopsychosocial variables and the severity of people with PHP. Secondly, to determine what combination of self-reported factors distinguishes people with PHP from other foot pain (OFP).

METHODS

We collected data from 235 participants, including 135 (%57) PHP (age 44 ± 12 years, 66% female) and 99 OFP (%43) (age 38 ± 11 years, 57% female) using 5 demographic, 13 biomedical, 8 psychological, 3 social and 8 activity-related factors. These were tested in linear and logistic regression models.

RESULTS

Quality of life (QoL) (β = 0.35; p < 0.001), education (β = -0.22; p = 0.003), gender (β = -0.20; p = 0.007), morning pain duration (β = -0.18; p = 0.01) and disease duration (β = -0.15; p = 0.040) were significantly associated with severity of PHP. The second model, without QoL, showed that having sensitisation (β = -0.18; p = 0.002) and a higher level of morning pain (β = -0.20; p = 0.01) are associated with severity. The logistic regression results revealed that people with PHP tend to have a systemic disease (OR = 3.34; 1.53-7.76), express more kinesiophobia (OR = 1.02; 1.01-1.14), are less likely to have previous injuries (OR = 0.40; 0.19-0.81), worse morning pain (OR = 1.02; 1.01-1.03) and standing pain (OR = 2.60; 1.39-4.87) compared to people with OFP.

CONCLUSIONS

People with PHP have higher associated levels of a range of psychological, social and activity related factors than people with OFP. The findings highlight the importance of considering psychosocial assessments alongside physical examination.

Effects of insoles adapted in flip-flop sandals in patients with persistent plantar heel pain: A sham-controlled randomised trial

OBJECTIVE

To evaluate the use of custom-made insoles adapted to flip-flops on pain intensity, foot function, and functional walking ability in individuals with persistent plantar heel pain in the short and medium term.

DESIGN

Randomised controlled trial.

SETTING

Flip-flop sandals in patients with persistent plantar heel pain.

MAIN MEASURES

Participants (n = 80) were assessed at baseline, six and 12 weeks after the intervention, and 4 weeks post-intervention.

RESULTS

For the primary outcomes, after 6 weeks of intervention, no between-group difference was observed in the intensity of morning pain or pain with walking, mean difference = -0.4 (95% confidence intervals = -1.5 to 0.8). Similarly, after 12 weeks of intervention, no between-group difference was observed in the intensity of morning pain or pain with walking, mean difference = -0.7 (95% confidence intervals = -1.9 to 0.6). Finally, at 4 weeks after the end of the intervention, there was no between-group difference in morning pain or pain on walking, mean difference = 0.01 (95% confidence intervals = -1.4 to 1.4). All differences and confidence intervals were smaller than the minimum clinically important difference for pain (2 points). There were no differences between the groups for the secondary outcomes. In addition, the mean differences were smaller than the minimum clinically important differences for pain intensity, foot function and functional walking ability.

CONCLUSION

Custom-made insoles fitted to flip-flops did not differ from flip-flops with sham insoles in improving pain intensity, foot function and functional walking ability in people with persistent heel pain.Trial registration: ClinicalTrials.gov (Identifier: NCT04784598).

Effects on pain of kinesiology tape in patients with plantar fasciitis: a randomized controlled study

PURPOSE.

Plantar fasciitis is the most frequent cause of heel pain. Custom-made plantar supports are a common treatment solution, while the application of kinesiology tape (KT) can be an effective measure to alleviate pain. The objective was to evaluate the effects of KT on the pain of patients with plantar fasciitis.

METHODS.

Randomized controlled trial including participants with plantar fasciitis. There was an experimental group (n = 17), whose participants underwent a KT treatment, and a control (sham tape) group (n = 17). The pain, measured with a visual analog scale (VAS), was the primary outcome and was assessed daily until the fifth day of wearing the tape and 24 h after removing it. Inferential statistics looked for time, group, and time per group differences with CI at 95%.

RESULTS.

The greatest between-group VAS difference was 3.5 points, and occurred at the 2-day follow-up assessment. Then, pain differences decreased over time until the last assessment point. Statistically significant time, group, and time*group differences were found with p < 0.001.

CONCLUSION.

This study supports that KT is effective in reducing pain in the short term in patients with plantar fasciitis, and more effective than a sham intervention with tape.

Pain improvement after three weeks of daily self-executed cross-friction massage using a fascia ball in a patient with recent-onset plantar heel pain: a case report

BACKGROUND

Plantar heel pain is described as sharp pain at the medial plantar aspect of the calcaneus and medial longitudinal arch of the foot. There are various treatment options that usually need a clinician or a therapist for application. The present case report aimed to describe the outcomes of self-executed cross-friction massage using a fascia ball in a patient with recent-onset plantar heel pain.

CASE DESCRIPTION

The patient was a 42-year-old man who reported plantar heel pain during the first steps in the morning along with decreased function of the foot and ankle lasting about three months. He was instructed to self-execute cross-friction massage using a fascia ball daily in the evening at home for six weeks.

OUTCOMES

Pain during treatment decreased from a Numeric Pain Rating Scale (NPRS)-score of 8/10 and from a Short-Form McGill Pain Questionnaire (SF-MPQ)-score of 34/60 at initial treatment to NPRS- and SF-MPQ-scores of 0/10 and 0/60, respectively, after about three weeks. The patient reported no pain and restored function after six weeks of treatment, and in the follow-up measurements.

DISCUSSION

Daily self-executed cross-friction massage using a fascia ball may be a useful alternative intervention for treating recent-onset plantar heel pain.

Comparison of Structural Diagnosis and Management (SDM) approach and MyoFascial Release (MFR) for improving plantar heel pain, ankle range of motion and disability: A randomized clinical trial

[Purpose] The purpose of this study was to compare the effectiveness of the Structural Diagnosis and Management (SDM) approach with Myofascial Release (MFR) in improving plantar heel pain, ankle range of motion, and disability. [Subjects] Sixty-four subjects, aged 30-60 years, with a diagnosis of plantar heel pain, plantar fasciitis, or calcaneal spur by a physician according to ICD-10, were equally allocated to the MFR (n = 32) and SDM (n = 32) groups by hospital randomization and concealed allocation. [Methods] In this assessor-blinded randomized clinical trial, the control group performed MFR to the plantar surface of the foot, triceps surae, and deep posterior compartment calf muscles, while the experimental group performed a multimodal approach utilizing the SDM concept for 12 sessions over 4 weeks. Both groups also received strengthening exercises, ice compression, and ultrasound therapy. Pain, activity limitations and disability were assessed as primary outcomes using the Foot Function Index (FFI) and Range of motion (ROM) assessment of the ankle dorsiflexors and plantar flexors using a universal goniometer. Secondary outcomes were measured using the Foot Ankle Disability Index (FADI) and a 10-point manual muscle testing process for the ankle dorsiflexors and plantar flexors. [Results] Both MFR and SDM groups exhibited significant improvements from baseline in all outcome variables, including pain, activity level, disability, range of motion, and function after the 12-week intervention period (p < .05). The SDM group showed more improvements than MFR for FFI pain (p < .01), FFI activity (p < .01), FFI (p < .01) and FADI (p = <.01). [Conclusion] Both MFR and SDM approaches are effective in reducing pain, improving function, ankle range of motion, and reducing disability in plantar heel pain, however, the SDM approach may be a preferred treatment option.

Adverse Events Reported in Trials Assessing Manual Therapy to the Extremities: A Systematic Review

Objective: This review aimed to describe the quality and comprehensiveness of adverse event (AE) reporting in clinical trials incorporating manual therapy (MT) as an intervention for extremity conditions using the Consolidated Standards of Reporting Trials (CONSORT)-Harms extension as the benchmark. The secondary aim was to determine whether the quality of AE reporting improved after the availability of the CONSORT reporting checklist. Design: Systematic review. Methods: A literature search was conducted using multiple databases to identify trials where MT was used to treat extremity conditions. Studies that reported AEs were identified and evaluated using the CONSORT-Harms extension. The frequency of trials reporting study AEs before and after the publication of the updated 2010 CONSORT statement was calculated, along with the categorization of how study AEs were reported. Results: Of the 55,539 studies initially identified, 220 trials met all inclusion criteria. Eighty trials (36.4%) reported AE occurrence. None of the studies that reported AEs adhered to all 10 criteria proposed by the 2010 CONSORT-Harms extension. The most commonly reported criterion was number four, which clarified how AE-related information was collected (30% of trials). The least reported criterion was number six, which describes the participant withdrawals for each arm due to AEs and the experience with the allocated treatment (1.3% of trials). The nomenclature used to describe AEs varied substantially. Fifty-nine of 76 trials (33.3%) were published after the updated CONSORT Harms-checklist was available, compared to 21 of 44 trials (46.7%) published before it was available. Conclusion: Reporting of AEs in trials investigating MT for extremity conditions is poor. Every included trial lacked adherence to all 10 criteria proposed by the CONSORT-Harms Extension. The quality and comprehensiveness of AE reporting did not improve after the most recent CONSORT update recommending AE reporting. Clinicians must obtain informed consent before performing any intervention, including MT, which requires disclosing potential risks, which could be better known with improved tracking, analyzing, and reporting of AEs. The authors recommend improved adherence to best practices for adequately tracking and reporting AEs in future MT trials.

Efficacy of heel lifts for lower limb musculoskeletal conditions: A systematic review

INTRODUCTION

The objective of this systematic review is to determine the benefits and harms of heel lifts to any comparator for lower limb musculoskeletal conditions.

METHODS

Ovid MEDLINE, Ovid AMED, Ovid EMCARE, CINAHL Plus and SPORTDiscus were searched from inception to the end of May 2024. Randomised, quasi-randomised or non-randomised trials comparing heel lifts to any other intervention or no-treatment were eligible for inclusion. Data was extracted for the outcomes of pain, disability/function, participation, participant rating of overall condition, quality of life, composite measures and adverse events. Two authors independently assessed risk of bias and certainty of evidence using the GRADE approach at the primary time point 12 weeks (or next closest).

RESULTS

Eight trials (n = 903), investigating mid-portion Achilles tendinopathy, calcaneal apophysitis and plantar heel pain were included. Heel lifts were compared to exercise, ultrasound, cryotherapy orthotics, stretching, footwear, activity modification, felt pads and analgesic medication. No outcome was at low risk of bias and few effects (2 out of 47) were clinically important. Low-certainty evidence (1 trial, n = 199) indicates improved pain relief (55.7 points [95% CI: 50.3-61.1], on a 100 mm visual analogue scale) with custom orthotics compared to heel lifts at 12 weeks for calcaneal apophysitis. Very low-certainty evidence (1 trial, n = 62) indicates improved pain and function with heel lifts over indomethacin (35.5 points [95% CI: 21.1-49.9], Foot Function Index) at 12 months for plantar heel pain.

CONCLUSIONS

Few trials have assessed the benefits and harms of heel lifts for lower limb musculoskeletal conditions. Only two outcomes out of 47 showed clinically meaningful between group differences. However, due to very low to low certainty evidence we are unable to be confident in the results and the true effect may be substantially different.

Comparison of the effectiveness of peloid therapy and kinesiotaping in patients with unilateral plantar fasciitis: A prospective, randomized controlled study

Objectives

This study aimed to compare the efficacy of peloid therapy and kinesiotaping for unilateral plantar fasciitis (PF).

Patients and methods

In the randomized controlled study, a total of 114 patients (89 females, 25 males; mean age: 45.1±8.3 years; range, 27 to 65 years) diagnosed with unilateral PF between January 2021 and March 2023 were randomly divided into three equal groups: the peloid group (peloid therapy and home-based exercise + heel pad), the kinesiotaping group (kinesiotaping and home-based exercise + heel pad), and the control group (home-based exercise + heel pad). Peloid therapy was performed over two weeks for a total of 10 sessions. Kinesiotaping was applied four times over two weeks. Plantar fascia, calf, and Achilles stretching exercises and foot strengthening exercises were performed, and prefabricated silicone heel insoles were used daily for six weeks. Patients were evaluated three times with clinical assessment scales for pain, the Heel Tenderness Index, and the Foot and Ankle Outcome Score before treatment, at the end of treatment, and in the first month after treatment.

Results

Statistically significant improvements were observed for all parameters at the end of treatment and in the first month after treatment compared to the baseline in every group (p<0.001). No superiority was found between the groups.

Conclusion

Peloid therapy or kinesiotaping, given as adjuncts to home-based exercise therapy and shoe insoles in patients with unilateral PF, did not result in additional benefits.

Effect of corticosteroids over plantar fascia thickness in plantar fasciitis: a systematic review and meta-analysis

OBJECTIVES

Corticosteroid injections have been typically used for the management of plantar fasciitis with apparently good clinical outcomes; however, there is no information of the effect of corticosteroids on the thickness of the plantar fascia which is typically altered in this pathology. We aimed determine whether treatment with corticosteroid injections induces plantar fascia thickness changes in plantar fasciitis.

METHODS

MEDLINE, Embase, Web of Science, and Scopus databases were searched for randomized controlled trials (RCT) reporting the use of corticosteroid injection to treat plantar fasciitis to July 2022. Studies must have reported plantar fascia thickness measurement. The risk of bias in all studies was assessed with the Cochrane Risk of Bias 2.0 tool. Meta-analysis was conducted using a random-effects model and the generic inverse variance method.

RESULTS

Data from 17 RCT (including 1109 subjects) were collected. The follow-up period ranged from one to six months. Most studies measured the thickness of the plantar fascia at the insertion into the calcaneus using ultrasound. Pooled analysis revealed that corticosteroid injections had no significant effect on plantar fascia thickness (weighted mean differences [WMD], 0.06 mm [95% CI: -0.17, 0.29]; p = 0.61) or pain relief (WMD, 0.12 cm [95% CI: -0.36, 0.61]; p = 0.62) above active controls.

CONCLUSION

Corticosteroid injections do not perform better than other common interventions in terms of a decrease of plantar fascia thickness and pain relief for plantar fasciitis.

Comparing two protocols of shock wave therapy for patients with plantar fasciitis: A pilot study

OBJECTIVES

This pilot study primarily aimed to detect the adherence as well as the effect size required to estimate the actual sample size needed for a larger scale study to compare and evaluate the effectiveness of two extracorporeal shock wave therapy (ESWT) protocols along, with a physical therapy program in reducing pain and improving function among patients suffering from plantar fasciitis. The study also aimed to report the effects of the ESWT protocols used on pain and function.

METHODS

A total of 26 participants took part in the study, including 17 females and 9 males. The average age of the participants was 34 years with a body mass index (BMI) of 23 kg/m2. Participants were divided into three equal groups; Group A received ESWT at a frequency of 15 Hz and intensity of 3, Group B received ESWT at a frequency of 10 Hz and intensity of 4, while Group C underwent the selected physical therapy program along with sham shock wave therapy as a control. Pain levels were assessed using the Visual Analog Scale (VAS) while functional improvements were evaluated using the Foot Function Index (FFI). Data was collected prior to treatment, after three sessions and at the end of six weeks (after six sessions).

RESULTS

The three groups were well matched, and the results revealed high adherence rates (90%, 90% and 80% respectively). Results also indicated reductions in pain levels and improvements in function for both intervention groups when compared to the control group. Group A demonstrated better outcomes compared to Group B while Group C showed relatively less improvement.

CONCLUSION

The study concluded a high adherence rate for the three groups as well as a small effect size detected of 0.282 that would suggest a total of 123 participants to be required to replicate the study on a larger scale. With regards to the findings of this pilot, the combination of ESWT and a targeted physical therapy program revealed a possible effective therapeutic approach for plantar fasciitis, with a higher frequency potentially yielding more favourable results.

Physiotherapy assessment and treatment of patients with tibial external fixator: a systematic scoping review

PURPOSE

To map evidence regarding physiotherapy assessment and treatment of patients with tibial external fixator (EF), and to point out literature gaps for further research.

METHODS

Systematic scoping review conducted in four databases. We included both experimental and non-experimental studies involving patients with tibial EF and outcomes of interest. We recorded study design, population, sample size, sample age, reason for EF use, type of surgery, type of EF used, instruments used for assessing function, pain, quality of life, satisfaction, psychosocial aspects, and physiotherapy treatment descriptions from included studies. We categorised data accordingly to outcomes assessed and physiotherapy treatments description.

RESULTS

Eighty-six studies were included involving 3070 patients. Causes of fixator use were traumatic conditions, acquired and congenital deformities, and non-traumatic conditions, like compartmental osteoarthritis. Function was assessed in about three-quarters of included studies, though other outcomes were not presented in most studies. Only one study described satisfactorily the physiotherapy treatment. Almost half of the studies did not provide any description of the rehabilitation process.

CONCLUSIONS

There is little evidence about the assessment of function, pain, quality of life, satisfaction, psychosocial aspects, and other outcomes in tibial EF patients. Physiotherapy treatment in these patients is poorly reported.Protocol registration: Open Science Framework: doi:10.17605/OSF.IO/UT2DA.

Evaluating and Characterizing the Scope of Care for Interventions Labeled as Manual Therapy in Low Back Pain Trials: A Scoping Review

OBJECTIVE

The purpose of this scoping review was to evaluate and characterize the scope of care for low back pain that falls under the specific label of manual therapy.

METHODS

PubMed database, Ovid MEDLINE, EMBASE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane Central Register of Controlled Trials (CENTRAL), and SPORTDiscus were searched from journal inception through May 2022 for randomized controlled trials that investigated the treatment of low back pain using manual therapy. Terminology used to define manual therapy was extracted and categorized by using only the words included in the description of the intervention. An expert consultation phase was undertaken to gather feedback.

RESULTS

One hundred seventy-six trials met final inclusion criteria, and 169 unique terms labeled as manual therapy for the treatment of low back pain were found. The most frequent terms were mobilization (29.0%), manipulation (16.0%), and thrust (6.4%). Eight percent of trials did not define or specify what type of manual therapy was used in the study. After removing duplicates, 169 unique terms emerged within 18 categories.

CONCLUSIONS

Manual therapy intervention labels used in low back pain trials are highly variable. With such variation, the heterogeneity of the intervention in trials is likely large, and the likelihood that different trials are comparing the same interventions is low. Researchers should consider being more judicious with the use of the term manual therapy and provide greater detail in titles, methods, and supplementary appendices in order to improve clarity, clinical applicability, and usefulness of future research.

IMPACT

The ability to interpret and apply findings from manual therapy-related research for low back pain is challenging due to the heterogeneity of interventions under this umbrella term. A clear use of terminology and description of interventions by researchers will allow for improved understanding for the role of manual therapy in managing back pain.

Barefoot walking is beneficial for individuals with persistent plantar heel pain: A single-blind randomized controlled trial

BACKGROUND

A lack of data exist about the effectiveness of active treatments for persistent plantar heel pain (PPHP).

OBJECTIVES

To compare short-term functional and clinical effects of a 4-week barefoot or shod treadmill walking program for people with PPHP.

METHODS

A single-blinded clinical trial randomized 52 participants with PPHP into either a barefoot walking group (BWG), or a shod walking group (SWG). All participants received therapeutic ultrasound. Outcomes were measured at baseline (t0), following 4 weeks of treatment (t1), and at 1-month follow-up (t2). The SF-36 functional questionnaire score was the main outcome. Secondary outcomes were self-reported and clinically-assessed pain provocation levels, pressure pain thresholds and pain tolerance. Treadmill walking time and speed were measured at t0 and t1; people also recorded the time spent walking each day in a diary.

RESULTS

The BWG exhibited significant improvements in all SF-36 items (except "emotional well-being") (P < 0.05), whereas the SWG exhibited improvements only in "pain" and "health change" items (P = 0.0001; effect size 0.13-0.94). Greater improvements were observed in the BWG than the SWG for "physical function" (P = 0.019) and "role limitations due to physical health" items (P = 0.035). Both groups demonstrated significant improvements in pain, with greater improvements in the BWG (P = 0.0001; effect size 0.89). Only the BWG showed significant improvements in pain pressure thresholds (P < 0.05; effect size 0.70) and pain tolerance (P < 0.001; effect size 0.67). Both groups significantly increased their speed and time spent walking on the treadmill (BWG Δ=19.7 min and Δ=1.7 km/h; SWG Δ=16.7 min and Δ=1.1 km/h) and time outdoors (SWG ∆=38.2 min/week; BWG mean ∆=48.5 min/week) (P < 0.001). All clinical tests of pain were significantly less positive in the BWG at all time points (P < 0.05).

CONCLUSIONS

Both walking programs benefited people with PPHP by alleviating pain and improving function and quality of life. Greater improvements were observed in the BWG than the SWG overall.

Consensus statements and guideline for the diagnosis and management of plantar fasciitis in Singapore

Introduction

Plantar fasciitis (PF) is a common cause of heel pain among the general population. The lack of standard practice guideline in Singapore presents challenges in education and clinical practice for this painful condition. These consensus statements and guideline were developed to streamline and improve the management of PF, covering key aspects such as diagnosis, investigations, risk factors, treatment modalities, monitoring and return to work/play.

Method

A multidisciplinary expert panel consisting of 6 sports physicians, 2 orthopaedic surgeons, 2 podiatrists and 1 physiotherapist from SingHealth Duke-NUS Sport & Exercise Medicine Centre (SDSC) was convened based on their clinical and academic experience with PF. The Grading of Recommen-dations, Assessment, Development and Evaluations (GRADE) approach was used to evaluate the quality of the evidence and subsequently prepare a set of clinical recommen-dations pertaining to the manage-ment of PF. A modified Delphi process was used to reach consensus.

Results

Eighteen consensus statements were developed to cover key components of PF management, from initial diagnosis to treatment modalities and finally, clinical progression. They were subsequently consolidated under a proposed treatment pathway guideline for PF.

Conclusion

The SDSC consensus statements and guideline provide concise recommendations for the management of PF in Singapore.

Small needle-knife versus extracorporeal shock wave therapy for the treatment of plantar fasciitis: A systematic review and meta-analysis

Background

Plantar fasciitis (PF) is the most common cause of chronic heel pain among adults. Extracorporeal shock wave therapy (ESWT) is the recommended in the current guidelines, and the small needle-knife yields acceptable clinical effects for musculoskeletal pain.

Objective

To systematically compare the efficacy of the small needle-knife versus ESWT for the treatment of PF.

Methods

The present review was registered in the International Prospective Register of Systematic Reviews (i.e., "PROSPERO", CRD42023448813). Two of the authors searched electronic databases for randomized controlled trials (RCTs) comparing the small needle-knife versus ESWT for the treatment of PF, and collected outcomes including curative effect, pain intensity, and function. Risk of bias was assessed using the Cochrane Handbook Risk of Bias tool and the quality of the RCTs was evaluated according to the Jadad Scale. The same authors independently performed data extraction from the included studies, which were imported into Review Manager version 5.4.1(Copenhagen: Nordic Cochrane Centre, The Cochrane Collaboration, 2020) for meta-analysis.

Results

The initial literature search retrieved 886 studies, of which 6 were eventually included in this study. Meta-analysis revealed no significant difference in curative effect (OR = 1.87; 95 % CI [0.80, 4.37], p = .15) nor short-term pain improvement (MD = 2.20; 95 % CI [-2.77, 7.16], p = .39) between the small needle-knife and ESWT. However, the small needle-knife may be more effective than ESWT for pain improvement in mid-term (MD = 9.11; 95 % CI [5.08, 13.15], p＜ .00001) and long-term follow-ups (MD = 10.71; 95 % CI [2.18, 19.25], p＜ .00001). Subgroup analysis revealed that the small needle-knife combined with a corticosteroid injection yielded a statistically significant difference in reduction of pain intensity at all follow-ups (MD = 4.84; 95 % CI [1.33, 8.36], p = .007; MD = 10.99; 95 % CI [8.30, 13.69], p＜ .00001; MD = 17.87; 95 % CI [15.26, 20.48], p＜ .00001). Meta-analysis revealed no statistical differences in short-term (MD = 1.34; 95 % CI [-3.19, 5.86], p = .56) and mid-term (MD = 2.75; 95 % CI [-1.21, 6.72], p = . 17) functional improvement between the needle-knife and ESWT groups. In a subgroup analysis of moderate-quality studies, the small needle-knife demonstrated a favorable effect on mid-term functional improvement (MD = 1.58; 95 % CI [0.52, 2.65], p = .004), with low heterogeneity (χ2 = 0.77, p = .038, I2 = 0 %). Conclusion: Pain reduction and functional improvement are essential for the treatment of PF. Therefore, treatment using the small needle-knife may be superior to ESWT. Results of this systematic review and meta-analysis may provide alternative treatment options for patients with PF as well as more reliable, evidence-based recommendations supporting use of the small needle-knife.

Photobiomodulation Therapy Plus Usual Care Is Better than Usual Care Alone for Plantar Fasciitis: A Randomized Controlled Trial

Background

Plantar fasciitis (PF) results in pain-related disability and excessive healthcare costs. Photobiomodulation therapy (PBMT) has shown promise for decreasing both pain and disability related to PF.

Purpose

The purpose was to assess the clinical impact of PBMT on pain and function in people with PF.

Study Design

Prospective, randomized controlled clinical trial.

Methods

A convenience sample of adults with PF were randomly assigned to one of three groups: (1) usual care, (2) usual care plus nine doses of PBMT with 25W output power over three weeks, or (3) usual care plus nine doses of PBMT with 10W output power over three weeks. Both 10W and 25W PBMT participants received the same total dose (10J/cm2) by utilizing a simple area equation. Pain (with Defense and Veterans Pain Rating Scale) and function (by Foot and Ankle Ability Measure) were measured at baseline, weeks 3, and 6 for all groups, and at 13 and 26 weeks for PBMT groups.

Results

PBMT groups experienced a reduction in pain over the first three weeks (from an average of 4.5 to 2.8) after which their pain levels remained mostly constant, while the UC group experienced a smaller reduction in pain (from an average of 4 to 3.8). The effects on pain were not different between PBMT groups. PBMT in both treatment groups also improved function more than the UC group, again with the improvement occurring within the first three weeks.

Conclusions

Pain and function improved during the three weeks of PBMT plus UC and remained stable over the following three weeks. Improvements sustained through six months in the PBMT plus UC groups.

There is a Lack of Clinical Homogeneity in Lower-Limb Tendinopathy Trials: A Scoping Review

OBJECTIVE: It is unclear if clinical trials of treatments for lower-limb tendinopathies include clinically homogeneous participant populations (an assumption for pooling in meta-analyses). We assessed the recruitment setting and participant characteristics used in randomized controlled trials (RCTs) that were investigating any treatment for lower-limb tendinopathies. DESIGN: Scoping review. METHODS: We conducted a systematic literature search in the PubMed, Embase, Cochrane CENTRAL, and Web of Science databases. All RCTs that were investigating treatments for lower-limb tendinopathies in an adult population (≥18 years) were eligible for inclusion. At least 2 authors conducted independent screening and selection of full-text papers, and extracted data from included studies. RESULTS: Of 18 341 records, 342 RCTs (21 897 participants) were eligible for inclusion and data extraction. The most common diagnoses were plantar fasciopathy (n = 195, 57%), Achilles tendinopathy (n = 82, 24%), and patellar tendinopathy (n = 41, 12%). Secondary care (n = 144, 42%) was the most reported recruitment setting, followed by an open setting (n = 44, 13%). In 93 (27%) RCTs, the recruitment setting was not described. We found high heterogeneity in participant characteristics (eg, symptom duration, age, body mass index, and the Victorian Institute of Sport Assessment [VISA] questionnaire score) within and between recruitment settings. CONCLUSION: Our results question whether clinical homogeneity can be adequately assumed in clinical trials of lower-limb tendinopathies due to the lack of clear reporting of the recruitment setting and the variability within and between recruitment settings of key participant characteristics. These findings threaten assumptions for meta-analyses in lower-limb tendinopathies. J Orthop Sports Phys Ther 2024;54(1):1-10. Epub 5 December 2023. doi:10.2519/jospt.2023.11722.

Evaluating Functional Performance Tests in those with Non-arthritic Intra-articular Hip Pain: An International Consensus Statement

Background

Non-arthritic intra-articular hip pain, caused by various pathologies, leads to impairments in range of motion, strength, balance, and neuromuscular control. Although functional performance tests offer valuable insights in evaluating these patients, no clear consensus exists regarding the optimal tests for this patient population.

Purpose

This study aimed to establish expert consensus on the application and selection of functional performance tests in individuals presenting with non-arthritic intra-articular hip pain.

Study Design

A modified Delphi technique was used with fourteen physical therapy experts, all members of the International Society for Hip Arthroscopy (ISHA). The panelists participated in three rounds of questions and related discussions to reach full consensus on the application and selection of functional performance tests.

Results

The panel agreed that functional performance tests should be utilized at initial evaluation, re-evaluations, and discharge, as well as criterion for assessing readiness for returning to sports. Tests should be as part of a multimodal assessment of neuromuscular control, strength, range of motion, and balance, applied in a graded fashion depending on the patient's characteristics. Clinicians should select functional performance tests with objective scoring criteria and prioritize the use of tests with supporting psychometric evidence. A list of recommended functional performance tests with varying intensity levels is provided. Low-intensity functional performance tests encompass controlled speed in a single plane with no impact. Medium-intensity functional performance tests involve controlled speed in multiple planes with low impact. High-intensity functional performance tests include higher speeds in multiple planes with higher impact and agility requirements. Sport-specific movement tests should mimic the patient's particular activity or sport.

Conclusion

This international consensus statement provides recommendations for clinicians regarding selection and utilization of functional performance tests for those with non-arthritic intra-articular hip pain. These recommendations will encourage greater consistency and standardization among clinicians during a physical therapy assessment.

Pain relief and functional improvement provided by extracorporeal shock wave therapy in plantar fasciitis is better than corticosteroid injection and kinesio taping: A randomized trial

Objectives

This study aimed to evaluate the results of extracorporeal shock wave therapy (ESWT), corticosteroid injection (CI), and kinesio taping (KT) in terms of pain and function in plantar fasciitis (PF).

Patients and methods

In this prospective study, 90 feet of 64 patients (11 males, 53 females; mean age: 38.3±10.4 years; range, 22 to 70 years) who presented with chronic PF between November 2021 and March 2022 were evaluated. The patients were randomized to three groups, with 30 feet in each group: the CI group, the ESWT group, and the KT group. Each group received only the respective treatment modalities assigned to their group. Pain assessment of the patients before the treatment and at six weeks, three months, and six months was evaluated with the Visual Analog Scale (VAS), and their functions were evaluated with the American Orthopedic Foot and Ankle Society (AOFAS) score.

Results

There was no statistical difference in the demographic data (age, body mass index, and VAS; all p>0.05). At six weeks, VAS was statistically significantly lower in the CI group compared to the other groups (p<0.001), but there was no difference in AOFAS between the groups (p=0.666). At three months, there was no statistical difference between the groups regarding VAS (p=0.311), while the AOFAS was higher in the ESWT group (p=0.006). At six months, VAS was lower (p<0.001) and AOFAS was higher (p=0.003) in the ESWT group.

Conclusion

All three commonly used treatment modalities, ESWT, CI, and KT, are effective in reducing pain and increasing function in chronic PF. However, while CIs can be more effective in relieving pain in the early period, the most significant improvement at the end of the sixth month was achieved by ESWT.

Effectiveness of Hypertonic Dextrose Injection (Prolotherapy) in Plantar Fasciopathy: A Systematic Review and Meta-analysis of Randomized Controlled Trials

OBJECTIVE

To systematically review the effectiveness of hypertonic dextrose prolotherapy (DPT) in plantar fasciopathy (PF) compared with other non-surgical treatments.

DATA SOURCES

PubMed/MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Web of Science, Allied and Complementary Medicine Database, Global Health, Ovid Nursing Database, Dimensions, and WHO ICTRP were searched from inception to April 30th, 2022.

STUDY SELECTION

Two independent reviewers selected randomized controlled trials (RCTs) that evaluated the effectiveness of DPT in PF compared with non-surgical treatments. Outcomes included pain intensity, foot and ankle function, and plantar fascia thickness.

DATA EXTRACTION

Two independent reviewers conducted data extraction. Risk of bias (RoB) assessment was conducted using the Cochrane Risk of Bias 2 (RoB 2) tool, and certainty of evidence was assessed with Grading of Recommendation Assessment, Development, and Evaluation (GRADE).

DATA SYNTHESIS

Eight RCTs (n=469) met the inclusion criteria. Pooled results favored the use of DPT versus normal saline (NS) injections in reducing pain (weighted mean difference [WMD] -41.72; 95% confidence interval [CI] -62.36 to -21.08; P<.01; low certainty evidence) and improving function [WMD -39.04; 95% CI -55.24 to -22.85; P<.01; low certainty evidence] in the medium term. Pooled results also showed corticosteroid (CS) injections was superior to DPT in reducing pain in the short term [standardized mean difference 0.77; 95% CI 0.40 to 1.14; P<.01; moderate certainty evidence]. Overall RoB varied from "some concerns" to "high". The overall certainty of evidence presented ranges from very low to moderate based on the assessment with the GRADE approach.

CONCLUSION

Low certainty evidence demonstrated that DPT was superior to NS injections in reducing pain and improving function in the medium term, but moderate certainty evidence showed that it was inferior to CS in reducing pain in the short term. Further high-quality RCTs with standard protocol, longer-term follow-up, and adequate sample size are needed to confirm its role in clinical practice.

Musculoskeletal Ultrasound for the Diagnosis of Plantar Fasciitis: An Accuracy and Diagnostic Yield Study

Objective

To evaluate the accuracy of musculoskeletal ultrasound measurement of plantar fascia thickness and shear wave elastography (SWE) calculation of Young's modulus in the diagnosis of plantar fasciitis (PFis), and to explore whether it will have any impact on clinical decision-making, rather than just using established diagnostic methods of clinical symptoms and signs.

Methods

A diagnostic single-center study was conducted in 60 patients with PFis and 64 patients with other types of heel pain. The sensitivity and specificity of musculoskeletal ultrasound in the diagnosis of PFis were calculated according to the diagnostic criteria for PFis recommended by the Clinical Practice Guide for PFis of the American Physical Therapy Association (APTA) Orthopaedic Branch. The analysis of the receiver operating characteristic curve of the subjects was used to study the accuracy of the diagnosis of PFis by two indicators alone and two indicators jointly.

Results

The thickness of plantar fascia measured by musculoskeletal ultrasound and the area under the curve (AUCs) calculated by shear wave elastography for diagnosing PFis were 0.925 and 0.917, respectively, and the optimal cutoff values were 3.15 mm (sensitivity: 100.0%, specificity: 81.3%) and 63.24 kPa (sensitivity: 78.3%, specificity: 92.2%), respectively. The area under the curve (AUCs) for the combined diagnosis of the two is 0.973 (sensitivity: 93.3%, specificity: 93.8%).

Conclusion

The thickness of plantar fascia measured by musculoskeletal ultrasound and Young's modulus calculated by SWE have high accuracy in diagnosing PFis, and the combined diagnosis of the two can improve the diagnostic accuracy of patients with PFis.

Effects of intrinsic foot muscle strengthening on the medial longitudinal arch mobility and function: A systematic review

OBJECTIVE

To Investigate the effects of intrinsic foot muscle (IFM) strengthening on foot's medial longitudinal arch (MLA) mobility and function in healthy individuals. We also identified exercise type and resistance training characteristics (series and repetitions).

METHODS

Eight databases were searched, between October 2020 and February 2021 and updated in May 2021. We included randomized controlled trials involving IFM strengthening exercises compared with controls (no exercise or exercises not involving isolated intrinsic foot muscle strengthening). Methodological quality of the studies was assessed using PEDro scale and Cochrane Risk of Bias tool. Quality of evidence was evaluated using GRADE model (Grading of Recommendations, Assessment, Development and Evaluations).

RESULTS

Four randomized controlled trials (RCT) were included. IFM strengthening did not change MLA mobility in the short-term (4 weeks); however, it promoted medium-term effects (8 weeks - low quality of evidence). IFM exercises improved function in the short and medium-term (low quality of evidence). Most studies used the short-foot exercise and the toe-towel curl exercise with contractions of 5 s and load progression from sitting to standing.

CONCLUSION

IFM strengthening exercises change MLA mobility in the medium-term (8 weeks) and improve the dynamic balance of healthy individuals in short- (4 weeks) and medium-terms.

The clinical and biomechanical effects of customized foot orthoses in individuals with plantar heel pain: A pre-post intervention study

BACKGROUND

Customized foot orthoses (CFOs) are often recommended for the management of plantar heel pain. However, there is a lack of information regarding lower limb and multi-segment foot motion during gait.

RESEARCH QUESTION

This study aimed to determine the effects of heat moulded CFOs on foot and lower limb kinematics when compared with prefabricated foot orthoses (PFOs) and wearing no orthoses (shod condition), and to determine the short-term effects of CFOs on pain intensity and foot function.

METHODS

The immediate effects of CFOs on the lower limb and multi-segment foot motion were assessed. Participants were then asked to use the CFOs for one month and foot pain, function, and temporal-spatial parameters were assessed at baseline and at one month follow up.

RESULTS

Thirty-five participants (22 females), aged 40.1 (10.5) years, with a mean duration of symptoms of 12.59 months were recruited. The symptomatic limbs showed a higher forefoot varus angle and greater rearfoot and forefoot corrections were required compared to the non-symptomatic limbs. When compared with PFOs and shod conditions, CFOs provided the least forefoot and knee motion in the transverse plane during contact phase (P < 0.05, d=0.844-1.720), least rearfoot motion in the coronal plane during midstance (P < 0.05, d=0.652), and least forefoot motion in the frontal plane, knee motion in the transverse plane, and hallux motion during the propulsive phase (P < 0.05, d=0.921-1.513). Significant improvements were seen for foot pain and function (P < 0.05, d=1.390-2.231) with significant increases in cadence and walking velocity after one month of CFO use (P < 0.05, d=0.315-0.353), and those most likely to respond had greater pain and less ankle eversion (P < 0.05, d=0.855-1.115).

SIGNIFICANCE

CFOs appear to improve pathological biomechanics associated with plantar heel pain. After one month follow up, the CFOs decreased pain intensity and increased foot function, and showed significant improvements in temporal and spatial parameters of gait.

Does a corticosteroid injection plus exercise or exercise alone add to the effect of patient advice and a heel cup for patients with plantar fasciopathy? A randomised clinical trial

OBJECTIVE

To compare the effectiveness of patient advice plus heel cup alone (PA) versus PA and lower limb exercise (PAX) versus PAX plus corticosteroid injection (PAXI) to improve self-reported pain in patients with plantar fasciopathy.

METHODS

We recruited 180 adults with plantar fasciopathy confirmed by ultrasonography for this prospectively registered three-armed, randomised, single-blinded superiority trial. Patients were randomly allocated to PA (n=62), PA plus self-dosed lower limb heavy-slow resistance training consisting of heel raises (PAX) (n=59), or PAX plus an ultrasound-guided injection of 1 mL triamcinolone 20 mg/mL (PAXI) (n=59). The primary outcome was changed in the pain domain of the Foot Health Status Questionnaire (ranging from 0 'worst' to 100 'best') from baseline to the 12-week follow-up. The minimal important difference in the pain domain is 14.1 points. The outcome was collected at baseline and at 4, 12, 26, and 52 weeks.

RESULTS

The primary analysis found a statistically significant difference between PA and PAXI after 12 weeks favouring PAXI (adjusted mean difference: -9.1 (95% CI -16.8 to -1.3; p=0.023)) and over 52 weeks (adjusted mean difference: -5.2 (95% CI -10.4 to -0.1; p=0.045)). At no follow-up did the mean difference between groups exceed the pre-specified minimal important difference. No statistically significant difference was found between PAX and PAXI or between PA and PAX at any time.

CONCLUSION

No clinically relevant between-group differences were found after 12 weeks. The results indicate that combining a corticosteroid injection with exercise is not superior to exercise or no exercise.

The effectiveness of shockwave therapy on patellar tendinopathy, Achilles tendinopathy, and plantar fasciitis: a systematic review and meta-analysis

Background

Tendinopathy is a growing global concern affecting many people, like athletes, workers, and the elderly. Despite its commonality among the sporting population, there is no practical clinical guideline for patellar tendinopathy (PT). Furthermore, there is conflicting evidence between clinical guidelines on shockwave therapy's application and clinical utility for Achilles tendinopathy (AT) and plantar fasciitis (PF). Thus, our aim of this study is to evaluate the evidence for shockwave therapy; to provide a Grading of Recommendation, Assessment, Development and Evaluation (GRADE) level of the evidence and effectiveness of shockwave therapy for patellar tendinopathy, Achilles tendinopathy, and Plantar fasciitis.

Method

Medical Literature Analysis and Retrieval System Online (Medline), Embase, The Cumulative Index to Nursing and Allied Health Literature (CINAHL), Physiotherapy Evidence Database (PEDro) and China National Knowledge Infrastructure database (CNKI) were searched to find relevant studies published before December 14th, 2022.

Results

Our study showed that for PT in the short term, extracorporeal shockwave therapy (ESWT) or ESWT + eccentric exercise (EE) has a negligible effect on pain and function compared to a placebo or placebo + EE. On the contrary, ESWT significantly affects pain compared to conservative treatment (CT). For AT, ESWT has a small inconclusive effect on pain and function in the short term compared to EE. On the other hand, a placebo outperformed ESWT in improving function for AT but not pain outcomes. PF showed that ESWT significantly affects short- and long-term pain and function. When ESWT was compared to other interventions such as low laser therapy (LLLT), corticosteroid injection (CSI), or CT, there was a small inconclusive effect on pain and function in the short term.

Conclusion

There is low-moderate evidence that ESWT has a negligible effect on pain and function for PT and AT. However, high-quality evidence suggests ESWT has a large effect on pain and function for PF.

Prevalence and Associated Factors of Ankle-Foot Pain Among Nurses Working in Surgical Units of Comprehensive Specialized Hospitals in Amhara Regional State, Northwest Ethiopia, 2022

Background

Ankle-foot pain is a serious public health concern among nurses and has a significant impact on the quality of the health care service delivery system. However, little is known about the prevalence and factors associated with ankle-foot pain among nurses working in surgical units in Ethiopia.

Purpose

The study aimed to assess the prevalence and associated factors of ankle-foot pain among nurses working in surgical units of comprehensive specialized hospitals in Amhara regional state, Northwest Ethiopia, 2022.

Participants and Methods

An institution-based cross-sectional study was conducted among 409 nurses working in surgical units of comprehensive specialized hospitals, from May 15 to June 7, 2022. A simple random sampling technique was employed. Data were collected by five BSc nurses using a structured self-administered questionnaire. The collected data were entered into Epi-data version 4.6 and exported to SPSS version 23 for analysis. The descriptive statistics and bivariable and multivariable logistic regression analyses were computed. Finally, variables were declared as statistically significant at P < 0.05 using the odds ratio and 95% CI.

Results

The prevalence of ankle-foot pain among nurses working in surgical units was 51.8% (95% CI = 46.9-57.5). More than 10 years of working experience [AOR = 3.48, 95% CI = 1.35-8.92], working 48 or more hours per week [AOR = 2.69, 95% CI = 1.27-6.00], prolonged standing [AOR = 5.72, 95% CI = 3.20-10.25], high physical job demand [AOR = 2.41, 95% CI = 1.53-3.80], and low job control [AOR = 2.34, 95% CI = 1.47-3.71] had statistically significant association with ankle-foot pain.

Conclusion

This study found that ankle-foot pain was common among nurses working in surgical units. Having more years of work experience, working more hours per week, prolonged standing, high physical job demand, and low job control were statistically associated with ankle-foot pain.

Myofascial stiffness of plantar fascia and Achilles tendon in individuals with plantar fasciopathy: An observational cross-sectional study

BACKGROUND

Assessment of myofascial tissue stiffness have a role in identifying physical impairments in plantar fasciopathy (PF). It is still unclear which specific functional and tissue differences exist between individuals with PF.

AIM

To compare myofascial stiffness of plantar fascia, Achilles tendon, and triceps surae between symptomatic and asymptomatic limbs in individuals with PF and between individuals with and without PF.

METHODS

Thirty nine individuals diagnosed with PF and individuals with no history of PF were recruited. Myofascial stiffness of the plantar fascia, Achilles tendon, and triceps surae, range of motion, and clinical tests were performed. Mean difference (MD) and 95% confidence interval (CI) were calculated.

RESULTS

Individuals with PF showed lower mean stiffness in Achilles tendon insertion (MD = -1.00 N/mm; 95%CI: -1.80,-0.21) on the symptomatic limb compared to the corresponding symptomatic limb in control group, a lower mean stiffness in plantar fascia (MD = -0.16 N/mm; 95%CI: -0.30, -0.01) on the symptomatic limb compared to asymptomatic limb, and a lower mean stiffness in the region 3 cm above the Achilles tendon insertion (MD = -0.79; 95%CI: -1.59, -0.00) compared to control. Individuals with PF showed fewer repetitions in heel rise test (MD = -3.97 reps; 95%CI: -5.83, -2.12) and in the step-down test (MD = -5.23 reps; 95%CI: -7.02, -3.44) compared to control.

CONCLUSIONS

Individuals with PF present reduced stiffness in Achilles tendon insertion and plantar fascia. The reduced stiffness was more evident in Achilles tendon in individuals with PF compared to individuals without PF. Individuals with PF showed lower performance in clinical tests.

The effects of a custom foot orthosis on dynamic plantar pressure in patients with chronic plantar fasciitis: A randomized controlled trial

BACKGROUND

Plantar fasciitis is one of the most common causes of heel pain. The plantar fascia supports the longitudinal arch and absorbs ground reaction forces during the static and dynamic phase(s) of weight-bearing. The purpose of this randomized controlled trial study was to determine the effects of CAD/CAM foot orthoses that were designed based on the dynamic plantar pressure in patients with plantar fasciitis.

METHODS

This study was performed on 34 patients with plantar fasciitis. Outcomes were compared based on plantar fascia thickness; peak pressure, mean pressure, and maximum force; and pain, activity of daily living, quality of life, and sports activity that were evaluated by ultrasound, plantar pressure platform, and the Foot and Ankle Outcome Score, respectively. The patients were randomly assigned into two groups: the experimental group (CAD/CAM orthoses and night splint) and the control group (night splint only). All data were recorded again after 4 weeks.

RESULTS

Pain ( P = 0.002) and plantar fascia thickness ( P = 0.001) decreased significantly after 1 month of intervention. Activity of daily living ( P = 0.044) and quality of life ( P = 0.001) showed a significant increase. There was a trend in increasing peak pressure in all masking regions in both groups. The maximum force remarkably reduced in the experimental group in all regions.

CONCLUSIONS

The results demonstrated that CAD/CAM foot orthoses designed based on dynamic plantar pressure with night splint can reduce the plantar fascia thickness and pain associated with plantar fasciitis and increase the activity of daily living, quality of life, and sports activity.

Effects of customized insoles with medial wedges on lower extremity kinematics and ultrasonographic findings in plantar fasciitis persons

The customized insole is widely recommended as an effective intervention for pain reduction and foot function improvement in plantar fasciitis persons. However, it is unclear whether the additional correction of medial wedges could change the kinematics from the only insole. The objectives of this study were thus to compare customized insoles with and without medial wedges on lower extremity kinematics during gait and to determine the short-term effects of the customized insole with medial wedges on pain intensity, foot function, and ultrasonographic findings in plantar fasciitis persons. A within-subject, randomized, crossover design within motion analysis research laboratory was conducted among 35 persons with plantar fasciitis. Main outcome measures included joint motions of the lower extremity and multi-segment foot, pain intensity, foot function, and ultrasonographic findings. The customized insole with medial wedges produced less knee motion in the transverse plane and hallux motion in all planes during the propulsive phase than that without medial wedges (all p < 0.05). After the 3-month follow-up, the insoles with medial wedges decreased pain intensity and increased foot function. Abnormal ultrasonographic findings also decreased significantly after the 3-month treatment of insoles with medial wedges. Customized insoles with medial wedges seem superior to those without medial wedges on both multi-segment foot motion and knee motion during propulsion. Positive outcomes from this study supported the use of customized insoles with medial wedges as an effective conservative treatment in patients with plantar fasciitis.Trial registration: TCTR20210928006 (28/09/2021).

Healthcare usage and cost for plantar fasciitis: a retrospective observational analysis of the 2010-2018 health insurance review and assessment service national patient sample data

BACKGROUND

Plantar fasciitis (PF) is the most common cause of heel pain in adults, and the number of patients and medical expenses are increasing annually. However, studies on this condition are lacking. There is a need to investigate universally administered PF treatment and the associated costs. Therefore we analyzed the South Korean Health Insurance Review and Assessment Service data to investigate the distribution and healthcare usage of patients with PF.

METHODS

A cross-sectional retrospective observational design was used in this study. Patients diagnosed with PF (ICD-10 code M72.2) between January 2010 and December 2018 in South Korea, of whom 60,079 had used healthcare at least once, were included in the study. We assessed healthcare usage and cost due to PF, treatment method, and visit route. All statistical analyses were performed with descriptive statistics using SAS 9.4 version.

RESULTS

The number of treated cases of PF and patients with PF was 11,627 cases and 3,571 patients in 2010, respectively, which increased annually to 38,515 cases and 10,125 patients by 2018, respectively. The 45-54-year-old age group had the highest number of patients; the patient population was predominantly women. Physical therapy was used frequently in Western medicine (WM) institutions, where > 50% of the medicines prescribed to outpatients were analgesics. In contrast, acupuncture therapy was most commonly used in Korean medicine (KM) institutions. A high percentage of patients who visited a KM institution, followed by a WM institution, and then returned to the same KM institution had visited the WM institution for radiological diagnostic examination.

CONCLUSION

This study analyzed nine years of period data from a patient sample of claims data from the Health Insurance Review and Assessment Service to examine the current status of health service use for PF in Korea. We obtained information on the status of WM/KM institution visits for PF treatment, which could be useful for health policymakers. Study findings regarding treatments often used in WM/KM, the frequency of treatments, and their costs could be used as basic data by clinicians and researchers.

Predicting the outcome of plantar heel pain in adults: a systematic review of prognostic factors

BACKGROUND

Plantar Heel Pain (PHP) is a common disorder with many treatment pathways and is not self-limiting, hence prognostic information concerning recovery or recalcitrance is needed to guide practice. In this systematic review, we investigate which prognostic factors are associated with favourable or unfavourable PHP outcomes.

METHODS

MEDLINE, Web of Science, EMBASE, Scopus and PubMed electronic bibliographic databases were searched for studies evaluating baseline patient characteristics associated with outcomes in prospective longitudinal cohorts or after specific interventions. Cohort, clinical prediction rule derivation and single arms of randomised controlled trials were included. Risk of bias was evaluated with method-specific tools and evidence certainty with GRADE.

RESULTS

The review included five studies which evaluated 98 variables in 811 participants. Prognostic factors could be categorised as demographics, pain, physical and activity-related. Three factors including sex and bilateral symptoms (HR: 0.49[0.30-0.80], 0.33[0.15-0.72], respectively) were associated with a poor outcome in a single cohort study. The remaining four studies reported twenty factors associated with a favourable outcome following shockwave therapy, anti-pronation taping and orthoses. Heel spur (AUC = 0.88[0.82-0.93]), ankle plantar-flexor strength (Likelihood ratio (LR): 2.17[1.20-3.95]) and response to taping (LR = 2.17[1.19-3.90]) were the strongest factors predicting medium-term improvement. Overall, the study quality was low. A gap map analysis revealed an absence of research that included psychosocial factors.

CONCLUSIONS

A limited number of biomedical factors predict favourable or unfavourable PHP outcomes. High quality, adequately powered, prospective studies are required to better understand PHP recovery and should evaluate the prognostic value of a wide range of variables, including psychosocial factors.

Ultrasound-Guided Autologous Platelet-Rich Plasma Injections Versus Focal Ultrasound-Guided Extracorporeal Shockwave Therapy for Plantar Fasciitis in Athletes and Nonathletes: A Retrospective Comparative Study With Minimum 2-Year Follow-Up

Plantar fasciitis is often cause of heel pain, especially in sporting-related activities. Different conservative measures for the management of plantar fasciitis were compared in several researches. The purpose of this retrospective study was to evaluate and compare clinical outcomes of chronic plantar fasciitis treated with ultrasound-guided platelet-rich plasma (PRP) and focal ultrasound-guided extracorporeal shockwave therapy (ESW). Secondarily, results on subpopulation of athletes were recorded. Fifty-five patients treated for plantar fasciitis were included, 24 among them were competitive or recreational athletes. Treatment outcomes were assessed using Visual Analog Scale and Foot Function Index before and after treatment. Time to return to sport among patients practicing sporting activities was recorded. Before treatment, no differences were observed between groups in terms of age, gender, body mass index, and months of follow up. From baseline to final follow-up assessment, significant improvement was observed in all the outcomes measures. The subgroup analysis showed no differences between patients stratified for type of treatment and sport/nonsport practitioners. The overall failure rate was higher, although not significant, in patients who underwent ESW therapy and they required a higher number of orthopedic visits. Among sports practitioners the mean time to return to sport (months) was faster in PRP group than ESW group (p = .044). PRP and ESW represent both reliable solutions for plantar fasciitis leading to good results in terms of patients' satisfaction, pain, and clinical outcomes. However, after treatment with PRP injections less recurrences in overall population and faster return to sporting activities in sports practitioners were observed.

The struggle to stay physically active-A qualitative study exploring experiences of individuals with persistent plantar fasciopathy

BACKGROUND

Plantar fasciopathy is the most common cause of heel pain, and is associated with decreased physical activity level and quality of life. There has been limited research on the experiences of patients with plantar fasciopathy. This study seeks to gain more in-depth understanding and knowledge by exploring the lived experiences of people with persistent plantar fasciopathy.

METHODS

We included 15 participants with longstanding plantar fasciopathy. Face-to-face, semi-structured interviews were audio recorded, transcribed verbatim and analysed using Braun and Clark's reflexive thematic analysis. We used an inductive approach led by a phenomenological theoretical framework.

RESULTS

We identified three core themes and ten sub-themes. The first theme was 'Struggling to stay active' with sub-themes 'Struggling with pain and how to adjust it', ' Finding alternative activities' and 'Longing for the experience of walking'. The second main theme was 'Emotional challenges' with the sub-themes 'Feelings of frustration and self-blame' and 'Worries of weight gain and related consequences'. The third main theme was 'Relations to others' with the sub-themes 'Participation in family and social life', ' Visible in new ways', ' Striving to avoid sick leave' and 'Bothering others'.

CONCLUSIONS

Participants revealed how their heel pain led to inactivity and emotional and social challenges. Pain when walking and fear of aggravating it dominated the participants' lives. They emphasised the importance of finding alternative ways to stay active and avoiding sick leave. Treatment should focus on holistic and individually tailored approaches.

Lack of standardization in dry needling dosage and adverse event documentation limits outcome and safety reports: a scoping review of randomized clinical trials

OBJECTIVES

Examine: (1) whether variability in dry needling (DN) dosage affects pain outcomes, (2) if effect sizes are clinically important, and (3) how adverse events (AE) were documented and whether DN safety was determined.

METHODS

Nine databases were searched for randomized controlled trials (RCTs) investigating DN in symptomatic musculoskeletal disorders. Methodological quality was assessed using the Physiotherapy Evidence Database (PEDro) scale. Included RCTs met PEDro criteria #1 and scored > 7/10. Data extraction included DN dosage, pain outcome measures, dichotomous AE reporting (yes/no), and AE categorization. Clinically meaningful differences were determined using the minimum clinically important difference (MCID) for pain outcomes .

RESULTS

Out of 22 identified RCTs, 11 demonstrated significant between-group differences exceeding the MCID, suggesting a clinically meaningful change in pain outcomes. Nine documented whether AE occurred. Only five provided AEs details and four cited a standard means to report AE.

DISCUSSION

There was inconsistency in reporting DN dosing parameters and AE. We could not determine if DN dosing affects outcomes, whether DN consistently produces clinically meaningful changes, or establish optimal dosage. Without more detailed reporting, replication of methods in future investigations is severely limited. A standardized method is lacking to report, classify, and provide context to AE from DN. Without more detailed AE reporting in clinical trials investigating DN efficacy, a more thorough appraisal of relative risk, severity, and frequency was not possible. Based on these inconsistencies, adopting a standardized checklist for reporting DN dosage and AE may improve internal and external validity and the generalizability of results.

Activity and footwear characteristics in people with and without plantar heel pain: A matched cross-sectional observational study

BACKGROUND

Activity and footwear may be associated with plantar heel pain (PHP), however both factors have rarely been investigated. The aim of this study was to investigate activity and footwear characteristics in PHP while controlling for important confounders.

METHOD

This cross-sectional observational study compared 50 participants with PHP to 25 participants without PHP who were matched for age, sex and body mass index. Activity was measured using the Stanford Activity Questionnaire, as well as the number of hours per day participants stood for, and whether they stood on hard floors. Footwear characteristics were measured using the footwear domain of the Foot Health Status Questionnaire (FHSQ), as well as the style of shoe, heel height, and the Shore A hardness value of the heel of the shoe most used.

RESULTS

Participants with PHP stood for more than twice as long as participants without PHP (mean difference 3.4 hours, p < 0.001, large effect size). Participants with PHP also reported greater difficulty accessing suitable footwear (FHSQ footwear domain mean difference (MD) 22 points, p = 0.002, large effect size (ES), and they wore harder-heeled shoes (Shore A MD 6.9 units, p = 0.019, medium ES). There were no significant differences for physical activity, whether they stood on hard floors, the style of shoe they wore, or heel height.

CONCLUSIONS

Compared to people without PHP, people with PHP stand for more than twice the amount of time each day, have substantial difficulties accessing suitable footwear, and the primary shoes they wear are harder under the heel.

Effects of dry needling and stretching exercise versus stretching exercise only on pain intensity, function, and sonographic characteristics of plantar fascia in the subjects with plantar fasciitis: a parallel single-blinded randomized controlled trial

OBJECTIVES

Plantar fasciitis is a common problem in the foot region which has negative considerable impact on foot function.

METHODS

In this parallel blinded randomized controlled trial, a total of thirty-seven subjects with plantar fasciitis (forty feet) were enrolled randomly to either the control group (stretching exercise) or the experimental group (stretching exercise plus dry needling). All interventions lasted six weeks and both groups were followed for two weeks. Primary outcomes were first step pain, pain, and activity daily function subscales of the FAOS questionnaire and secondary outcomes were plantar fascia thickness, and echogenicity.

RESULTS

The mixed model ANOVAs showed significant group × time interactions for all primary outcomes. In both groups, first step pain and both subscales of the FAOS questionnaire were improved compared to baseline measurements. There were considerable differences between the two groups and the experimental group experienced more improvements in primary outcomes compared to the control group. For secondary outcomes, plantar fascia thickness at insertion significantly decreased, and the echogenicity in the two regions significantly increased in the experimental group compared to the control group.

CONCLUSION

These results suggest that the combination of dry needling and stretching exercises can be an effective conservative treatment for plantar fasciitis subjects.

An assessment of plantar fascia with ultrasound findings in patients with plantar fasciitis: a systematic review

INTRODUCTION

Plantar fasciitis (PFS) is described by an intense pain over medial tubercle of calcaneus, increased with the first step after waking up, after rest and during weightbearing activity. It is the most common cause of plantar heel pain in adults with the prevalence estimated 10% of the general population. Ultrasound imaging is commonly being used to measure the PF thickness, evaluate the efficacy of different treatments and a guide therapeutic technique in patients with PFS. The objective of this study was to systematically review the studies that were previously published to evaluate the role of ultrasound in the assessment of PF in patients with PFS.

METHODS

A systematic search was carried out over the last 5 years from 2017 to 2022 on basis the following electronic databases: Science Direct, Scopus, Web of Science, Springer and PubMed. The keywords that used in the searching were: ultrasound, sonography, ultrasonography, plantar fasciitis, imaging of plantar fascia, physiotherapy of plantar fasciitis, interventional treatment of plantar fasciitis, randomized controlled trial of plantar fasciitis and interventional ultrasound. The review focused on the assessment of PF in patients with PFS underwent different interventions using B-mode, shear wave elastography (SWE) and color Doppler ultrasound.

RESULTS

During the search process, 1661 were recorded using the proper keywords from 2017 to 2022 in which 666 original articles were found after removing the review and duplicated articles. Of these, thirty articles met the inclusion criteria and included in this review. The articles have assessed the PF in patients with PFS under different conditions using different ultrasound modes. Twenty-six articles evaluated the effectiveness of different treatment on PF in patients with PFS using different ultrasound modes. In 8 of 26 articles, the ultrasound was used as both an assessment tool of PF and guide therapeutic technique in patients with PFS. In 18 articles, the ultrasound was used as only assessment tool to identify the PF thickness and its observation changes in patients with PFS. Four articles compared the PF thickness and its intrafascial changes between patients with PFS and healthy subjects.

CONCLUSION

The ultrasound can be a reliable tool in assessment the effect of different interventions on PF by evaluating its thickness, echogenicity and stiffness changes in patients with PFS. There were different methods and treatments were used among the studies.

Effectiveness of dextrose prolotherapy for the treatment of chronic plantar fasciitis: A systematic review and meta-analysis of randomized controlled trials

OBJECTIVE

To systematically investigate the efficacy and safety of dextrose prolotherapy for treating chronic plantar fasciitis.

LITERATURE SURVEY

EMBASE, PubMed, Scopus, and Google Scholar (from inception to December 9, 2021).

METHODOLOGY

Comprehensive review of randomized controlled trials investigating dextrose prolotherapy for chronic plantar fasciitis was done. Two investigators independently screened the titles, abstracts, and full texts and extracted data from eligible studies. The changes in visual analog scale (VAS) pain score, foot function index (FFI), American Orthopaedic Foot and Ankle Society (AOFAS) score, and plantar fascia thickness were analyzed. Reports of complications of the procedure were collected.

SYNTHESIS

Eight randomized controlled trials (RCTs) were included in the meta-analysis, analyzing 444 patients in total. The subgroup analysis showed that at short-term follow-up (<6 months) dextrose prolotherapy was more effective in reducing VAS pain score compared to the non-active treatment control group including exercise and normal saline solution (NSS) injection. However, there was no difference in the change of VAS pain score between dextrose prolotherapy and active treatment control group, which included extracorporeal shock wave therapy (ESWT), steroid injection, and platelet-rich plasma (PRP) injection. Dextrose prolotherapy was more effective in reducing FFI, increasing AOFAS score, and reducing plantar fascia thickness at short-term (<6 months) follow-up compared to other comparators. For long-term (≥6 months) follow-up, there was no significant difference in the change in VAS pain score and FFI between the dextrose prolotherapy group and other comparators. No serious complication was reported.

CONCLUSIONS

Dextrose prolotherapy is an effective treatment of chronic plantar fasciitis to reduce pain, improve foot functional score, and decrease plantar fascia thickness at short-term follow-up. Further studies in larger populations are needed to identify the optimal treatment regimen including dextrose concentration, volume, injection site, injection technique, and the number of injections required. The long-term effects of these treatments also require further examination.

The effect of dextrose prolotherapy versus placebo/other non-surgical treatments on pain in chronic plantar fasciitis: a systematic review and meta-analysis of clinical trials

BACKGROUND

Prolotherapy is the injection of a small volume of sclerosing or irritant solutions into an injured tissue. We aimed to investigate the effect of dextrose prolotherapy (DPT) versus placebo/other non-surgical treatments on pain in chronic plantar fasciitis.

METHODS

We searched seven electronic databases (PubMed/MEDLINE, Web of Science, EMBASE, Scopus, ProQuest, CENTRAL, PEDro) from inception to December 31, 2021 with no language restriction for publications comparing the effect of DPT with placebo/other non-surgical treatments in patients with chronic plantar fasciitis. Our primary outcome was pain and the secondary outcomes were foot function and plantar fascia thickness. The risk of bias was assessed using the Cochrane Collaboration's tool.

RESULTS

Overall, eight studies with a total of 449 patients were included in the meta-analysis. All the included studies reported short-term pain. A large effect size (dppc2 = -0.97, 95% confidence interval [CI] -1.84 to -0.10) was observed favoring the use of DPT to reduce pain in patients with chronic plantar fasciitis in the short-term. The results for foot function improvement (dppc2 = -1.28, 95% CI -2.49 to -0.07) and plantar fascia thickness reduction (dppc2 = -1.02, 95% CI -1.99 to -0.05) in the short-term were also in favor of DPT.

CONCLUSIONS

Since almost all the included studies had high risk of bias and multiple trials lacked long-term follow-ups, further high-quality research is required to determine the long-term effects of DPT vs placebo/other non-surgical interventions.

Effect of plantar fascia-specific stretching and Achilles tendon stretching on shear wave elasticity of the plantar fascia in healthy subjects

BACKGROUND

The effect of stretching on the mechanical properties of the plantar fascia (PF) remain unclear. This study was performed to determine the effect of PF-specific stretching (PFSS) and Achilles tendon stretching (ATS) on the viscoelastic properties of the PF with shear wave elastography (SWE).

METHODS

We recruited 14 participants (8 men, 6 women) with no history of PF disorders or painful episodes. The mean age of the participants was 30.9 ± 4.8 (range, 25-41) years. All participants performed sustained PFSS (sPFSS) on one foot and intermittent PFSS (iPFSS) on the other foot. Two weeks later, all participants performed sustained ATS (sATS) on one foot and intermittent ATS (iATS) on the other foot. SWE measurements were performed immediately after each stretching.

RESULTS

The PF elasticity immediately before stretching ranged from 133.8 kPa to 144.7 kPa. The PF elasticity after stretching ranged from 158.9 kPa to 215.8 kPa. There was a significant increase in PF elasticity after sPFSS, iPFSS, sATS, and iATS (P < .01). The elasticity after sATS was greater than that after iATS (P = .03). In contrast, there were no differences in PF elasticity after stretching between sPFSS and iPFSS (P = .13), sPFSS and sATS (P = .17), or iPFSS and iATS (P = .50).

CONCLUSIONS

PF elasticity increased after stretching regardless of the frequency and type of PFSS and ATS.

LEVEL OF EVIDENCE

Level II, prospective cohort study.

Lower Extremity Muscle Performance and Foot Pressure in Patients Who Have Plantar Fasciitis with and without Flat Foot Posture

Abnormal foot posture and poor muscle performance are potential causes of plantar fasciitis (PF). However, no study has compared the differences between lower extremity muscle performance and foot pressure in patients who have PF with and without abnormal foot postures. This study aimed to compare the differences in lower extremity muscle performance, such as in the hip, quadriceps, hamstring, and plantar flexor, and foot pressure in patients who have PF with and without flat foot postures. Seventy patients with plantar heel pain were enrolled (37 flat feet and 33 without flat feet). The hip muscle strength was measured using a handheld digital dynamometer. The strength and reaction time of the quadriceps, hamstring, and plantar flexor muscles were evaluated using an isokinetic device. Foot pressure parameters were assessed using pedobarography. The strength of the plantar flexor muscles was significantly lower (p = 0.008), while the reaction time of the plantar flexor muscles was significantly faster (p = 0.007) for the involved feet of PF patients with flat feet than in those without flat feet. This study confirmed the differences in muscle performance between patients who have PF with different foot postures. Therefore, clinicians and therapists should plan treatment considering the differences in these characteristics for the management of these patients.

Extracorporeal Shockwave Therapy Versus Graston Instrument-Assisted Soft-Tissue Mobilization in Chronic Plantar Heel Pain: A Randomized Controlled Trial

BACKGROUND

Although there are studies showing that extracorporeal shockwave therapy (ESWT) and instrument-assisted soft-tissue mobilization methods are effective in chronic plantar heel pain (CPHP) treatment, there is a need for studies comparing these techniques. We compared the effectiveness of ESWT versus instrument-assisted soft-tissue mobilization using Graston Technique (GT) instruments in addition to stretching exercises (SEs) in CPHP.

METHODS

Sixty-nine patients were randomly assigned to three groups: ESWT+SEs (group 1), GT+SEs (group 2), and SEs only (control group) (ratio, 1:1:1). The SEs, twice daily for 8 weeks, were standard for all. Group 1 received low-intensity ESWT; in group 2, GT was the selected method. Visual analog scales (for initial step and activity pain), the Foot Function Index (FFI), the 12-item Short-Form Health Survey (SF-12), and the Tampa Scale for Kinesiophobia were used pretreatment, posttreatment, and at 8-week and 6-month follow-up.

RESULTS

Visual analog scale and FFI scores improved posttreatment and during follow-up in all groups (P < .001). Although effect sizes were greater in groups 1 and 2 than in the control group in initial step pain posttreatment and at 8-week follow-up, group 2 had the highest effect size at 6 months. Mean SF-12 scores in groups 1 and 2 improved on the posttreatment assessment. Furthermore, group 2 showed significant improvements in FFI scores compared with the other groups at 6-month follow-up (F = 6.33; P = .003).

CONCLUSIONS

Although ESWT+SEs and GT+SEs seem to have similar effects on initial step pain posttreatment and at 8-week follow-up, GT+SEs was found most effective for improving functional status at 6 months in the management of CPHP.

Elasticity evaluation of the plantar fascia: A shear wave elastography study involving 33 early-stage plantar fasciopathy subjects

Background: Plantar fasciopathy, the most common foot condition seen in elderly and athletic populations, can be diagnosed and differentially diagnosed with imaging modalities such as ultrasound shear wave elastography (SWE). However, standard guidelines for ultrasound elastography of the plantar fascia are lacking. The purpose of this study was to determine the impact of the region of interest (ROI) on the evaluation of the plantar fascia elasticity and confirm the screening accuracy of SWE in the early-stage of plantar fasciopathy. Methods: This was an observational case‒control study involving 50 feet of 33 early-stage plantar fasciopathy subjects (the plantar fasciopathy group) and 96 asymptomatic feet of 48 healthy volunteers (the non-pain group). Clinical information, including age, gender, height, weight, visual analogue scale (VAS) score, American Orthopaedic Foot and Ankle Scale score (AOFAS), and the symptom duration, were recorded. All participants underwent both conventional ultrasound and SWE evaluation. The plantar fascia elastic parameters included SWE_single-point, calculated with a single-point ROI set at the greatest thickness of the plantar fascia, and SWE_multi-point, calculated by multipoint ROIs set continuously from the origin at the calcaneus to about 2 cm from the calcaneal origin. Results: The plantar fasciopathy group presented a higher VAS score (median [IQR), 4.00 (3.00) vs. 0.00 (0.00), p < 0.001] and lower AOFAS score [median (IQR), 79.50 (3.00) vs. 100.00 (10.00), p < 0.001] than the non-pain group. The median plantar fascia thickness of the plantar fasciopathy group was significantly greater than that of the non-pain group [median (IQR), 3.95 (1.37) mm vs 2.40 (0.60) mm, p < 0.001]. Abnormal ultrasound features, including echogenicity, border irregularities, and blood flow signals, were more prominent in the plantar fasciopathy group than in the non-pain group (29% vs. 0%, p < 0.001; 26% vs. 1%, p < 0.001; 12% vs. 0%, p < 0.001, respectively). Quantitative analysis of the plantar fascia elasticity revealed that the difference between the value of SWE_single-point and SWE_multipoint was significant [median (IQR), 65.76 (58.58) vs. 57.42 (35.52) kPa, p = 0.02). There was a moderate and significant correlation between the value of SWE_single-point and heel pain. However, there was no correlation between the value of SWE_multipoint and heel pain. Finally, we utilized the results of SWE_single-point as the best elastic parameter reflecting clinical heel pain and found that SWE_single-point could provide additional value in screening early-stage plantar fasciopathy, with an increase in sensitivity from 76% to 92% over conventional ultrasound alone. Additionally, compared with conventional ultrasound and SWE, the use of both improved the accuracy of screening for plantar fasciopathy. Although there were no significant differences in the negative predictive value of conventional ultrasound, SWE, and their combination, the positive predictive value when using both (90.20%) was significantly greater than that when using conventional ultrasound (74.50%) or SWE alone (76.50%). Conclusion: The plantar fascia elastic parameter calculated with single-point ROIs set at the greatest thickness of the plantar fascia is positively correlated with fascia feel pain. Single-point analysis is sufficient for the screening of the early-stage plantar fasciopathy using SWE. SWE_single-point may provide additional valuable information for assessing the severity of plantar fasciopathy.

The Short-Term Effect of Dynamic Tape versus the Low-Dye Taping Technique in Plantar Fasciitis: A Randomized Clinical Trial

BACKGROUND

Plantar fasciitis is a painful disorder that affects the plantar fascia of the foot, with a multifactorial aetiology. Dorsal flexion deficiency in the ankle is a risk factor for it. The provisional use of taping is described as part of conservative treatment. Dynamic Tape^® is a type of tape that, adhered to muscles, allows for potential elastic energy to accumulate and dissipate later, optimizing its function. Therefore, it can offer immediate benefits while the patient awaits definitive treatment depending on the cause.

OBJECTIVE

To verify the effectiveness of Dynamic Tape^® and the low-dye taping technique on pain intensity, ankle range of motion, and foot posture index.

METHOD

A randomised, double-blind clinical trial was conducted. A total of 57 subjects from the Clinical Podiatry Area of the University of Seville (Spain), clinically diagnosed with plantar fasciitis, were randomized into two groups. For one week, in the gastrocnemius-Achilles-plantar system, one group was treated with Dynamic Tape^® and another group with low-dye taping. Pain, degrees of movement of dorsal flexion, and the foot posture index were measured in both groups before the intervention and one week after the intervention. A repeated-measures analysis of variance (ANOVA) was used to explore the differences between groups.

RESULTS

Significant differences in the decrease in pain intensity using Dynamic Tape^® were found when comparing the treatments (p = 0.015) and the foot posture index was more normal in low-dye taping (p < 0.001). In both cases, the treatment showed similar behaviour with respect to the dorsal flexion ankle movement.

CONCLUSION

The effectiveness of Dynamic Tape^®, compared to that of the low-dye taping, has a major benefit with regard to pain intensity from fasciitis, although it does not produce changes in the ankle range of motion and foot posture index. Consequently, Dynamic Tape^® can be considered a taping technique with beneficial effects on pain intensity in the provisional approach to plantar fasciitis.

Effects of insoles adapted in flip-flop sandals for persistent heel pain: a protocol for a sham-controlled randomised trial

INTRODUCTION

Persistent heel pain is a prevalent complaint affecting up to 10% of the population. Insoles adapted in flip-flop sandals are an alternative treatment for pain and function of individuals with persistent heel pain, showing improvement within 12 weeks of treatment. Most studies considered foot posture and biomechanics to prescribe insoles for persistent heel pain, but few verified the effects of a 12-week treatment on pain catastrophising. This study will investigate the effects of insoles adapted in flip-flop sandals on pain intensity, function, functional walking capacity and pain catastrophising of individuals with persistent heel pain.

METHODS AND ANALYSIS

This is a protocol for a sham-controlled randomised trial. Eighty individuals with persistent heel pain will be assessed and randomised into two intervention groups: insoles adapted in flip-flop sandals and flip-flop sandals with sham (ie, flat) insoles. Assessments will be conducted at baseline (T0), after 6 weeks (T6), 12 weeks postintervention (T12) and after a 4-week follow-up (T16). The primary outcome will be the pain intensity, and secondary outcomes will be foot function, functional walking capacity and pain catastrophising. Analysis of variance with mixed design (if normal distribution) or Friedman's test (if not normal distribution) will verify intergroup and intragroup differences. Bonferroni post hoc tests will be performed in case of significant group or time interaction. Intent-to-treat analysis will be used, and a significance level of 5% and 95% CIs will be considered.

ETHICS AND DISSEMINATION

This study was approved by the research ethics committee of the Federal University of Rio Grande do Norte (registry no. 4,018,821). Results will be disseminated to individuals, submitted to a peer-reviewed journal and disclosed in scientific meetings.

Treatment Approaches for Plantar Fasciopathy in Elite Athletes: A Scoping Review of the Literature

Background

Plantar fasciopathy is a common orthopaedic condition that affects athletes and limits their performance.

Purpose

To conduct a scoping review of the literature to summarize the evidence provided so far for the management of plantar fasciopathy in elite athletes and identify potential gaps in the current knowledge.

Study Design

Scoping review; Level of evidence, 5.

Methods

This scoping review followed the 6-stage methodological framework of Arksey and O'Malley and was registered in the Open Science Framework. PubMed, Scopus, and Web of Science were used to identify eligible articles. After charting of data, studies were pooled into 3 categories: epidemiological/diagnostic studies, outcome research focused on plantar fasciitis or partial tears, and studies on the rupture of the plantar fascia. The modified Coleman Methodology Score was used to assess the quality of included articles.

Results

Of 742 initial studies, 10 were selected (109 patients): 8 level 4 articles and 2 level 5 articles. In 4 studies (91 athletes), potential risk factors were discussed but not investigated (ie, preexistent thickening of the fascia, spike shoes, varus hindfoot/knee alignment). In 3 studies (6 athletes) focusing on plantar fasciitis, the nonsurgical treatment led to a satisfactory but poorly documented outcome. In 3 studies (12 athletes), the rupture of the fascia was treated nonoperatively with contrasting results, while surgery was performed only in 2 cases. The mean modified Coleman Methodology Score was 19 (range, 3-42), demonstrating overall poor methodology.

Conclusion

The limited number of studies and their poor quality do not allow to define the gold standard treatment of plantar fasciopathy in elite athletes. Until high-quality studies are provided, clinicians have to rely on the available literature regarding the nonprofessional or nonathletic population to make the best evidence-based decision.
