The effectiveness of conservative, non-pharmacological treatment, of plantar heel pain: A systematic review with meta-analysis

Minimally invasive surgical treatments versus non-surgical treatments or placebo for plantar fasciopathy: A systematic review

BACKGROUND

Due to advances in minimally invasive surgical treatments (MIST), this systematic review with a narrative synthesis aimed to investigate the effectiveness of MIST in improving pain compared with non-surgical treatment or placebo in patients with plantar fasciopathy (PF).

METHODS

We systematically searched relevant databases for peer-reviewed studies comparing MIST to non-surgical treatments or placebo.

RESULTS

Eight studies were included. The results demonstrated statistically significant superiority in pain reduction for percutaneous needle treatments compared to non-surgical treatments or placebo in five studies. One study compared endoscopic plantar fascia release to exercise and corticosteroid injections and found a statistically significant superiority of endoscopic plantar fascia release.

CONCLUSIONS

This systematic review found promising effects of needle treatments to reduce pain among patients with PF. Endoscopic plantar fascia release was superior to the comparator in one of three studies. High risks of bias and methodological heterogeneity limit the strength of the available evidence.

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.

Wearable Technology Applications and Methods to Assess Clinical Outcomes in Foot and Ankle Disorders: Achievements and Perspectives

Foot and ankle disorders are a very common diseases, represent a risk factor for falls in older people, and are associated with difficulty performing activities of daily living. With an increasing demand for cost-effective and high-quality clinical services, wearable technology can be strategic in extending our reach to patients with foot and ankle disorders. In recent years, wearable sensors have been increasingly utilized to assess the clinical outcomes of surgery, rehabilitation, and orthotic treatments. This article highlights recent achievements and developments in wearable sensor-based foot and ankle clinical assessment. An increasing number of studies have established the feasibility and effectiveness of wearable technology tools for foot and ankle disorders. Different methods and outcomes for feasibility studies have been introduced, such as satisfaction and efficacy in rehabilitation, surgical, and orthotic treatments. Currently, the widespread application of wearable sensors in clinical fields is hindered by a lack of robust evidence; in fact, only a few tests and analysis protocols are validated with cut-off values reported in the literature. However, nowadays, these tools are useful in quantifying clinical results before and after clinical treatments, providing useful data, also collected in real-life conditions, on the results of therapies.

Is radial extracorporeal shock wave therapy (rESWT), sham-rESWT or a standardised exercise programme in combination with advice plus customised foot orthoses more effective than advice plus customised foot orthoses alone in the treatment of plantar fasciopathy? A double-blind, randomised, sham-controlled trial

OBJECTIVES

To assess whether radial extracorporeal shock wave therapy (rESWT), sham-rESWT or a standardised exercise programme in combination with advice plus customised foot orthoses is more effective than advice plus customised foot orthoses alone in alleviating heel pain in patients with plantar fasciopathy.

METHODS

200 patients with plantar fasciopathy were included in a four-arm, parallel-group, sham-controlled, observer-blinded, partly patient-blinded trial. At baseline, before randomisation, all patients received advice plus customised foot orthoses. Patients were randomised to rESWT (n=50), sham-rESWT (n=50), exercise (n=50) or advice plus customised foot orthoses alone (n=50). Patients in the rESWT and sham-rESWT groups received three treatments. The exercise programme comprised two exercises performed three times a week for 12 weeks, including eight supervised sessions with a physiotherapist. Patients allocated to advice plus customised foot orthoses did not receive additional treatment. The primary outcome was change in heel pain during activity in the previous week per Numeric Rating Scale (0-10) from baseline to 6-month follow-up. The outcome was collected at baseline, and 3, 6 and 12 months.

RESULTS

The primary analysis showed no statistically significant between-group differences in mean change in heel pain during activity for rESWT versus advice plus customised foot orthoses (-0.02, 95% CI -1.01 to 0.96), sham-rESWT versus advice plus customised foot orthoses (0.52, 95% CI -0.49 to 1.53) and exercise versus advice plus customised foot orthoses (-0.11, 95% CI -1.11 to 0.89) at 6 months.

CONCLUSION

In patients with plantar fasciopathy, there was no additional benefit of rESWT, sham-rESWT or a standardised exercise programme over advice plus customised foot orthoses in alleviating heel pain.

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.

Dose Escalation Can Enhance the Therapeutic Potential of Radial Extracorporeal Shock-Wave Therapy in the Treatment of Plantar Fasciitis in Runners

Background and Objectives: Treatment of chronic plantar fasciitis is challenging given that there are various of available treatment options with no clear gold standard. The aim of the study was to examine the dose-escalation effect of rESWT on the biomechanical parameters of the plantar fascia and pain ailments. Materials and Methods: In the experimental group (n = 30), the intensity of the shock wave was increased every two subsequent treatment sessions. In the control group (n = 32), the treatment parameters were not changed. In both groups, six treatments were performed, with two treatment sessions a week. In order to assess the biomechanical parameters of the plantar fascia, myotonometric measurements were performed. The pain intensity was assessed using the Visual Analog Scale (VAS). Results: The tension of the plantar fascia attachment in the experimental group decreased from 27.69 ± 2.06 [Hz] before treatment to 26.29 ± 1.69 [Hz] after treatment (p = 0.009) and to 26.03 ± 2.15 [Hz] 1 month after the beginning of treatment (p = 0.003). In the control group, the frequency results did not change significantly (p > 0.05). Flexibility increased in both groups. The test results before treatment and 1 month after the beginning of the treatment showed statistical significance in the experimental group (p = 0.001) vs. (p = 0.002) in the control group. The differences were not statistically significant between groups (p > 0.05). The assessment of pain intensity carried out 1 month after the end of treatment in the experimental group amounted to 3.14 ± 2.28 points, which was statistically significantly lower compared to that in the control group, where it amounted to 5.14 ± 1.92 points. (p < 0.001). Conclusions: The use of rESWT performed with an increasing intensity of impact during subsequent treatment procedures demonstrated greater effectiveness in improving the biomechanical parameters of the plantar fascia and was also more effective in reducing the pain ailments. Our results are encouraging. The dose escalation in the treatment cycle is worth considering. To prove that this method of treatment is more effective, a randomized controlled trial should be carried out on a representative sample.

Conservative Treatment of Sever's Disease: A Systematic Review

Background: Sever's disease, or calcaneal apophysitis, stands as the most prevalent cause of heel pain in children, often linked to sports like soccer, Australian football, and basketball. While various therapies are documented in the scientific literature, the standard choice is conservative treatment. Thus, the objective of this research was to assess the effectiveness of diverse conservative methods and techniques in alleviating Sever's disease symptoms. Methods: Systematic searches were conducted in October 2023 in PubMed, Web of Science, Scopus, SportDiscus, and PEDro, using terms like Osteochondritis, Osteochondrosis, Apophysitis, Sever's disease, Calcaneus, Adolescent, Child, and Childhood. The PEDro scale gauged methodological quality, and the Cochrane Risk of Bias tool evaluated the risk of bias. Results: Eight randomized controlled studies were included, featuring commonly used treatments such as insoles, therapeutic exercises, Kinesio taping, and foot orthoses. The methodological quality was generally good, with an average PEDro score of 6.75 points. Regarding bias, four articles had low risk, three had high risk, and one had some concern. Conclusions: Conservative treatment emerges as an effective option for alleviating symptoms associated with Sever's disease.

A New Minimally Invasive Procedure for Treating Plantar Heel Pain: Stromal Vascular Fraction Gel Grafting

METHODS

Fourteen patients who experienced plantar heel pain and underwent plantar heel SVF-gel grafting between January 2019 and June 2020 were included in this retrospective study. Foot pain and disability were measured at the screening visit and at the 3-, 6-, and 12-month follow-up visits. The volume of the heel fat pad was measured by magnetic resonance imaging.

RESULTS

Four of the patients had bilateral plantar heel pain, and 10 patients had unilateral plantar heel pain. All patients showed significant improvements in pain and foot function at 3 months after SVF-gel grafting compared with the baseline, with the greatest improvement at 6 months and the effect lasting 1 year or more. In addition, the thickness of the heel fat pad was significantly greater than at baseline at 3 months, and the effect lasted for 1 year or more.

CONCLUSION

Stromal vascular fraction gel grafting is a safe, minimally invasive, and effective approach to treat plantar heel pain.

Development of a foot and ankle strengthening program for the treatment of plantar heel pain: a Delphi consensus study

BACKGROUND

People with plantar heel pain (PHP) have reduced foot and ankle muscle function, strength and size, which is frequently treated by muscle strengthening exercises. However, there has been little investigation of what exercises are used and there is no sound evidence base to guide practice. This study aimed to develop a consensus-driven progressive muscle strengthening program for PHP.

METHODS

Thirty-eight experts were invited to participate in the study over three rounds. Round 1 was an open-ended questionnaire that provided the core characteristics of progressive strengthening programs designed for three different adult patient types with PHP (younger athletic, overweight middle-aged, older), which were presented as vignettes. In Round 2, experts indicated their agreement to the proposed exercises and training variables. In Round 3, experts were presented with amendments to the exercises based on responses from Round 2 and indicated their agreement to those changes. Consensus was achieved when > 70% of experts agreed.

RESULTS

Two experts were ineligible and 12 declined, leaving 24 (67%) who participated in Round 1. Eighteen (75%) completed all three rounds. From Round 1, progressive strengthening programs were developed for the three vignettes, which included 10 different exercises and three training variables (sets / repetitions, weight, and frequency). In Round 2, 68% (n = 17) of exercises and 96% (n = 72) of training variables reached consensus. In Round 3, only exercise changes were presented and 100% of exercises reached consensus.

CONCLUSIONS

This study provides three progressive strengthening programs agreed to by experts that can be used in future clinical trials to determine the effectiveness of muscle strengthening for PHP. In addition, clinicians could use the programs as part of a rehabilitation strategy with the caveat that they may change as more research is conducted.

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.

Efficacy and safety of non-pharmacological interventions for endotracheal suctioning pain in preterm infants: A systematic review

AIM

To review and analyse the evidence on the efficacy and safety of non-pharmacological interventions for preterm infants to relieve endotracheal suctioning (ES) pain.

DESIGN

A systematic review per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

METHODS

Six databases were searched with a retrieval strategy. Parallel and crossover randomized controlled trials reporting non-pharmacological interventions for relieving ES pain in preterm infants were identified from inception to 1 September 2021. The protocol was published in PROSPERO (CRD42021276058).

RESULTS

Ten studies were retrieved, including nine different non-pharmacological interventions. Seven studies reported that non-pharmacological interventions in relieving pain were more effective than conventional care during ES, and three trials reported its safety. Due to the heterogeneity of pain assessment tools, time of assessment and population, only Facilitated tucking had sufficient evidence that it is a safe and effective non-pharmacological intervention.

Effects of therapeutic interventions on pain due to plantar fasciitis: A systematic review and meta-analysis

OBJECTIVE

To determine the effects of different therapeutic interventions that have ever been evaluated in randomized controlled trials on pain due to plantar fasciitis.

METHODS

We searched different electronic databases until September 2022. Mean differences (MDs) and 95% confidence intervals (CIs) were calculated. The Grading of Recommendations Assessment, Development and Evaluation was used to evaluate the overall certainty evidence.

RESULTS

A total of 236 studies met the study criteria, including 15,401 patients. Botulinum toxin MD -2.14 (CI: -4.15, -0.14), micronized dehydrated human amnion/chorion membrane injection MD -3.31 (CI: -5.54, -1.08), dry needling MD -2.34 (CI: -4.64, -0.04), low-dye taping MD -3.60 (CI: -4.16, -3.03), low-level laser therapy MD -2.09 (CI: -2.28, -1.90), myofascial releases MD -1.79 (CI: -2.63, -0.94), platelet-rich plasma MD -2.40 (CI: -4.16, -0.63), radiofrequency MD -2.47 (CI: -4.65, -0.29), and stretching MD -1.14 (CI: -2.02, -0.26) resulted in being effective treatments for pain when compared to the control in the short term. In the medium and long term, only extracorporeal shock wave therapy MD -0.97 (CI: -1.13, -0.81)/MD -2.49 (CI: -3.17, -1.82) was effective for improving pain when compared to the control.

CONCLUSIONS

Considering the available studies, this systematic review and meta-analysis showed that different therapeutic interventions seem to be useful strategies for improving pain in patients with plantar fasciitis. In the medium and long term, only extracorporeal shock wave therapy was effective in improving pain when compared to the control.

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.

Surgical or non-surgical treatment of plantar fasciopathy (SOFT): study protocol for a randomized controlled trial

Background

Plantar fasciopathy is the most common reason for complaints of plantar heel pain and one of the most prevalent musculoskeletal conditions with a reported lifetime incidence of 10%. The condition is normally considered self-limiting with persistent symptoms that often last for several months or years. Multiple treatments are available, but no single treatment appears superior to the others. Heavy-slow resistance training and radiofrequency microtenotomy for the treatment of plantar fasciopathy have shown potentially positive effects on short- and long-term outcomes (> 3 months). However, the effect of heavy-slow resistance training compared with a radiofrequency microtenotomy treatment is currently unknown. This trial compares the efficacy of heavy-slow resistance training and radiofrequency microtenotomy treatment with supplemental standardized patient education and heel inserts in improving the Foot Health Status Questionnaire pain score after 6 months in patients with plantar fasciopathy.

Methods

In this randomized superiority trial, we will recruit 70 patients with ultrasound-confirmed plantar fasciopathy and randomly allocate them to one of two groups: (1) heavy-slow resistance training, patient education and a heel insert (n = 35), and (2) radiofrequency microtenotomy treatment, patient education and a heel insert (n = 35). All participants will be followed for 1 year, with the 6-month follow-up considered the primary endpoint. The primary outcome is the Foot Health Status Questionnaire pain domain score. Secondary outcomes include the remaining three domains of the Foot Health Status Questionnaire, a Global Perceived Effect scale, the physical activity level, and Patient Acceptable Symptom State, which is the point at which participants feel no further need for treatment.

Discussion

By comparing the two treatment options, we should be able to answer if radiofrequency microtenotomy compared with heavy-slow resistance training is superior in patients with plantar fasciopathy.

Efficacy of low-level laser therapy in patients with lower extremity tendinopathy or plantar fasciitis: systematic review and meta-analysis of randomised controlled trials

OBJECTIVES

We investigated the effectiveness of low-level laser therapy (LLLT) in lower extremity tendinopathy and plantar fasciitis on patient-reported pain and disability.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

Eligible articles in any language were identified through PubMed, Embase and Physiotherapy Evidence Database (PEDro) on the 20 August 2020, references, citations and experts.

ELIGIBILITY CRITERIA FOR SELECTION OF STUDIES

Only randomised controlled trials involving participants with lower extremity tendinopathy or plantar fasciitis treated with LLLT were included.

DATA EXTRACTION AND SYNTHESIS

Random effects meta-analyses with dose subgroups based on the World Association for Laser Therapy treatment recommendations were conducted. Risk of bias was assessed with the PEDro scale.

RESULTS

LLLT was compared with placebo (10 trials), other interventions (5 trials) and as an add-on intervention (3 trials). The study quality was moderate to high.Overall, pain was significantly reduced by LLLT at completed therapy (13.15 mm Visual Analogue Scale (VAS; 95% CI 7.82 to 18.48)) and 4-12 weeks later (12.56 mm VAS (95% CI 5.69 to 19.42)). Overall, disability was significantly reduced by LLLT at completed therapy (Standardised Mean Difference (SMD)=0.39 (95% CI 0.09 to 0.7) and 4-9 weeks later (SMD=0.32 (95% CI 0.05 to 0.59)). Compared with placebo control, the recommended doses significantly reduced pain at completed therapy (14.98 mm VAS (95% CI 3.74 to 26.22)) and 4-8 weeks later (14.00 mm VAS (95% CI 2.81 to 25.19)). The recommended doses significantly reduced pain as an add-on to exercise therapy versus exercise therapy alone at completed therapy (18.15 mm VAS (95% CI 10.55 to 25.76)) and 4-9 weeks later (15.90 mm VAS (95% CI 2.3 to 29.51)). No adverse events were reported.

CONCLUSION

LLLT significantly reduces pain and disability in lower extremity tendinopathy and plantar fasciitis in the short and medium term. Long-term data were not available. Some uncertainty about the effect size remains due to wide CIs and lack of large trials.

Effectiveness of Dry Needling of Myofascial Trigger Points in the Triceps Surae Muscles: Systematic Review

This study aims to analyze the effects of Dry Needling (DN) for the release of myofascial trigger points (MTrPs) in the triceps surae muscles (TSM). A systematic review was performed up to February 2022 in PubMed, PEDro, Scopus, CENTRAL, and Web of Science. Selection criteria were studies involving subjects older than 18 years presenting MTrPs in the TSM, without any concomitant acute or chronic musculoskeletal conditions; DN interventions applied to the MTrPs of the TSM; and results on pain, range of motion (ROM), muscle strength, muscle stiffness, and functional outcomes. The PEDro scale was used to assess the methodological quality of the studies, and the Risk of Bias Tool 2.0 to assess risk of bias. A total of 12 studies were included in the systematic review, involving 426 participants. These results suggest that DN of MTrPs in TSM could have a positive impact on muscle stiffness and functional outcomes. There are inconclusive findings on musculoskeletal pain, ROM, and muscle strength. Significant results were obtained in favor of the control groups on pressure pain thresholds. Despite the benefits obtained on muscle stiffness and functional performance, the evidence for the use of DN of MTrPs in the TSM remains inconclusive.

Effect of low-level laser therapy on pain and disability in patients with plantar fasciitis: A systematic review and meta-analysis

OBJECTIVE

We performed a systematic review to investigate the effects of low-level laser therapy (LLLT) on pain and disability in patients with plantar fasciitis (PF).

METHODS

We searched Pubmed, PEDro database, Scielo, and Cochrane Central for randomized controlled trials that evaluated the effects of LLLT for patients with PF. The methodological aspects of the studies included were scored using the PEDro scale. Three comparisons were made: LLLT compared with placebo, LLLT combined with conventional rehabilitation (CR) compared with CR and LLLT compared with extracorporeal shock wave therapy.

RESULTS

Fourteen studies (817 patients) met the study criteria. Compared to the placebo group, LLLT improved pain (MD, -2.3; 95% CI: 2.6 to -2, I² = 0%; 4 studies, N = 234: moderate-quality evidence) in the short term (0-6 weeks). No significant difference in short-term disability was found for participants in the LLLT group compared to the placebo group. Compared to the CR group, LLLT combined with CR improved pain (MD, -2.0; 95% CI: 2.9 to -1.1, I² = 0%; 2 studies, N = 90: moderate-quality evidence) in the short term (0-6 weeks). Compared to extracorporeal shock wave therapy, LLLT did not significantly reduce pain intensity in the short term (MD, 0.5; 95% CI: 2.0 to 2.9, I² = 96%; 4 studies, N = 175: low-quality evidence).

CONCLUSIONS

LLLT may improve pain in the short term and can be considered as a component of care of patients with PF. However, this superiority disappeared compared to extracorporeal shock wave therapy.

Effects of custom-made insoles on foot pressure redistribution, gait parameters, and pain in calcaneal apophysitis-a pretest and posttest study

BACKGROUND

Calcaneal apophysitis is a self-limiting disorder that often affects adolescents with a high level of activity and leads to increased pain severity, impairments in gait parameters, and poor health-related quality of life.

OBJECTIVE

To investigate the combination of custom-made insoles and exercise on foot pressure distribution, spatial-temporal gait parameters, and pain intensity in patients with calcaneal apophysitis.

STUDY DESIGN

A one-group pretest-posttest design.

METHODS

Forty patients, aged between 8 and 15 years, diagnosed with calcaneal apophysitis, were included in this study. Patients were asked to use the custom-made insoles and to perform a home exercise program for 3 days a week. The duration of treatment was 4 weeks. The pain severity was evaluated with the Visual Analog Scale. The spatial-temporal gait parameters and foot pressure distribution were assessed with the Zebris FDM-THM-S treadmill system before and after the treatment.

RESULTS

At posttreatment assessment, there were significant changes in step length, stance phase percentage, swing phase percentage, and gait speed (P < 0.05), except step width and cadence (P > 0.05). Moreover, significant differences were found in forefoot, midfoot, and rearfoot pressure distribution (P < 0.05). There was also a significant decrease in pain intensity during activity compared to the pretreatment (P < 0.05).

CONCLUSION

Our study results suggest that the combination of the custom-made insoles and exercise program created improvements in spatial-temporal gait parameters and foot pressure distribution by reducing the pain severity.

A Systematic Review of Systematic Reviews on the Epidemiology, Evaluation, and Treatment of Plantar Fasciitis

The number of systematic review and meta-analyses on plantar fasciitis is expanding. The purpose of this review was to provide a comprehensive summary of reviews on the topic pertaining to plantar fasciitis, identify any conflicting and inconsistent results, and propose future research direction. A qualitative review of all systematic reviews and meta-analyses related to plantar fasciitis up to February 2021 was performed using PubMed, Embase, Web of Science, and the Cochrane Database. A total of 1052 articles were initially identified and 96 met the inclusion criteria. Included articles were summarized and divided into the following topics: epidemiology, diagnosis, and treatment. While the majority of reviews had high level of heterogeneity and included a small number of studies, there was general consensus on certain topics, such as BMI as a risk factor for plantar fasciitis and extracorporeal shockwave therapy as an effective mode of therapy. A qualitative summary of systematic reviews and meta-analyses published on plantar fasciitis provides a single source of updated information for clinicians. Evidence on topics such as the epidemiology, exercise therapy, or cost-effectiveness of treatment options for plantar fasciitis are lacking and warrant future research.

Efficacy of Individualized Homeopathic Medicines in Plantar Fasciitis: Double-blind, Randomized, Placebo-Controlled Clinical Trial

INTRODUCTION

 Plantar fasciitis (PF) is a chronic degenerative condition causing marked thickening and fibrosis of the plantar fascia, and collagen necrosis, chondroid metaplasia and calcification. There is little convincing evidence in support of various approaches, including homeopathy, for treating PF. This study was undertaken to examine the efficacy of individualized homeopathic medicines (IHMs) compared with placebo in the treatment of PF.

METHODS

 A double-blind, randomized, placebo-controlled trial was conducted at the outpatient departments of Mahesh Bhattacharyya Homoeopathic Medical College and Hospital, West Bengal, India. Patients were randomized to receive either IHMs or identical-looking placebo in the mutual context of conservative non-medicinal management. The Foot Function Index (FFI) questionnaire, as an outcome measure, was administered at baseline, and every month, up to 3 months. Group differences (unpaired t-tests) and effect sizes (Cohen's d) were calculated on an intention-to-treat sample. The sample was analyzed statistically after adjusting for baseline differences.

RESULTS

 The target sample size was 128; however, only 75 could be enrolled (IHMs: 37; Placebo: 38). Attrition rate was 9.3% (IHMs: 4, Placebo: 3). Differences between groups in total FFI% score favored IHMs against placebo at all the time points, with large effect sizes: month 1 (mean difference, -10.0; 95% confidence interval [CI], -15.7 to -4.2; p = 0.001; d = 0.8); month 2 (mean difference, -14.3; 95% CI, -20.4 to -8.2; p <0.001; d = 1.1); and month 3 (mean difference, -23.3; 95% CI, -30.5 to -16.2; p <0.001; d = 1.5). Similar significant results were also observed on three FFI sub-scales (pain%, disability%, and activity limitation%). Natrum muriaticum (n = 14; 18.7%) and Rhus toxicodendron and Ruta graveolens (n = 11 each; 14.7%) were the most frequently prescribed medicines. No harms, serious adverse events, or intercurrent illnesses were recorded in either of the groups.

CONCLUSION

 IHMs acted significantly better than placebo in the treatment of PF; however, the trial being underpowered, the results should be interpreted as preliminary only. Independent replications are warranted.

Is Dry Needling Effective for the Management of Plantar Heel Pain or Plantar Fasciitis? An Updated Systematic Review and Meta-Analysis

OBJECTIVE

Dry needling is commonly used for the management of plantar fasciitis. This meta-analysis evaluated the effects of dry needling over trigger points associated with plantar heel pain on pain intensity and related disability or function.

METHODS

Electronic databases were searched for randomized controlled trials in which at least one group received dry needling, not acupuncture, for trigger points associated with plantar heel pain and in which outcomes were collected on pain intensity and related disability. The risk of bias was assessed with the Cochrane Risk of Bias tool, methodological quality was assessed with the Physiotherapy Evidence Database (PEDro) score, and the level of evidence is reported according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. Between-groups mean differences (MD) and standardized mean differences (SMD) were calculated.

RESULTS

The search identified 297 publications, with six trials eligible for inclusion. The meta-analysis found low-quality evidence that trigger point dry needling reduces pain intensity in the short term (MD -1.70 points, 95% confidence interval [CI] -2.80 to -0.60; SMD -1.28, 95% CI -2.11 to -0.44) and moderate-quality evidence that it improves pain intensity (MD -1.77 points, 95% CI -2.44 to -1.11; SMD -1.45, 95% CI -2.19 to -0.70) and related disability (SMD -1.75, 95% CI -2.22 to -1.28) in the long term, as compared with a comparison group. The risk of bias of the trials was generally low, but the heterogeneity of the results downgraded the level of evidence.

DISCUSSION

Moderate- to low-quality evidence suggests a positive effect of trigger point dry needling for improving pain intensity and pain-related disability in the short term and long term, respectively, in patients with plantar heel pain of musculoskeletal origin. The present results should be considered with caution because of the small number of trials.

Intra-arterial Infusion of Temporary Embolic Material in a Patient with Plantar Fasciitis: A Case Report

This case report concerns a 51-year-old woman with a 6-month history of severe right heel pain diagnosed as plantar fasciitis (PF) treated with intra-arterial infusion of imipenem/cilastatin (IPM/CS) through a 24G indwelling needle directly inserted into the posterior tibial artery (PTA). Angiography of the indwelling needle immediately before the infusion of IPM/CS demonstrated an increased number of abnormal vessels at the calcaneal attachment of the plantar fascia. Two procedures were planned: The first procedure was performed, and the second was performed 1 month after the first. A week after the first treatment, her pain gradually decreased. Three months after the first treatment, she no longer had difficulties with activities of daily living. Intra-arterial infusion of IPM/CS directly through an indwelling needle into the PTA represents a minimally invasive embolic treatment option for PF.

Cross-Cultural Adaptation and Validation of the Pain Scale for Plantar Fasciitis to Spanish

The aim of this study was the validation and transcultural adaptation of the Pain Scale for Plantar Fasciitis to Spanish, following the steps defined by "Guidelines for the process of cross-cultural adaptation of self-report measures." A cross-sectional study was driven in 153 patients with unilateral plantar fasciitis diagnosis. Statistical analysis measured the internal consistency, the test-retest reliability, the construct validity with the Spanish version of Foot and Function Index, and a factorial analysis. The questionnaire Pain Scale for Plantar Fasciitis was also given to a group of 10 people who received a physiotherapy treatment based on manual therapy, therapeutic exercise, and health education, which aim was to determine the questionnaire's sensitivity to changes. The questionnaire showed high internal consistency and test-retest reliability (Cronbach's α = 0.99, intraclass correlation coefficient = 0.98 [0.97-0.98]), good convergent validity with a moderate correlation with the Foot and Function Index (rho = 0.677, p < .0001) and no floor or ceiling effects were detected. The factorial analysis revealed that the first 3 factors showed 42.47% of variance, finding only 1 latent feature. Statistically significant differences were found in those patients who received physiotherapy treatment after 1 month, revealing that the questionnaire was sensitive to changes in the symptoms of subjects with plantar fasciitis. The Spanish version of Pain Scale for Plantar Fasciitis has proved to be a valid, reliable, and change-sensitive tool for patients with plantar fasciitis.

The analgesic efficacy of extracorporeal shock wave combined with percutaneous vertebroplasty in the treatment of osteoporotic thoracolumbar compression fractures in postmenopausal women

BACKGROUND

To explore the analgesic efficacy of extracorporeal shock wave (ESW) combined with percutaneous vertebroplasty (PVP) after reduction in overextension position in the treatment of osteoporotic thoracolumbar compression fractures in postmenopausal women.

METHODS

The data of postmenopausal women with osteoporotic thoracolumbar compression fracture admitted in our department from January 2017 to October 2019 were analyzed retrospectively. They were divided into groups of unipedicular percutaneous kyphoplasty (U-PKP n = 21), bipedicular PKP (B-PKP n = 20), and ESW combined with PVP after reduction in overextension position (EP-PVP n = 18). The improvement of pain and vertebral height in three groups was compared.

RESULTS

Postoperative compression rate and Cobb angle of vertebral fractures in the three groups were all lower than those before surgery, and the differences between pre-operation and post-operation were statistically significant (P < 0.05). The visual analog scale (VAS) and Oswestry dysfunction index (ODI) scores of the three groups decreased significantly after the operation (P < 0.05). The ODI scores of the EP-PVP group in the third months after the operation were significantly improved compared with the other two groups, and the difference was statistically significant (P < 0.05).

CONCLUSIONS

In our small-sample study, all three treatment schemes can treat osteoporotic compression fracture of thoracolumbar vertebrae in postmenopausal women, relieve pain, and improve quality of life. ESW combined with PVP after reduction in overextension position could achieve a good vertebral reduction rate and improve kyphosis, and may reduce the application of analgesic drugs.

Comparison of effects of low-level laser therapy and extracorporeal shock wave therapy in calcaneal spur treatment: A prospective, randomized, clinical study

Objectives

In this study, we aimed to evaluate and compare the efficacy of low-level laser therapy (LLLT) and extracorporeal shock wave therapy (ESWT) in the treatment of calcaneal spurs.

Patients and methods

A total of 62 patients (14 males, 48 females; mean age: 47.6±11.7 years; range, 18 to 70 years) who were diagnosed with calcaneal spurs based on clinical examination and plain radiography between April 2019 and September 2019 were included in this study. A total of 15 sessions of plantar fascia gastroc-soleus stretching exercises and cold pack treatments were given to both groups. The LLLT (904 nm wavelength, 3,000 Hz, 8 J/cm2 dose to the painful heel area and insertion of the plantar fascia on the medial calcaneal area, five points for a total of 5 min for three weeks) was applied to the first group (n=31), whereas ESWT (10 Hz, 2,000 shock waves with a 2.5 bar pressure into the areas of the painful heel, insertion of the plantar fascia on the medial calcaneal area) was applied the second group (n=31). All patients were evaluated using the Visual Analog Scale (VAS) and Foot Function Index (FFI) before and after treatment.

Results

In both groups, the median VAS and FFI scores after treatment showed a significant improvement, compared to pre-treatment scores (p=0.001). There was no significant difference between the groups in terms of the median post-treatment VAS scores (p>0.05). In the ESWT group, the median FFI pain and total scores after treatment were significantly lower than in the LLLT group (p=0.033). The change in the median FFI pain and total scores were significantly higher in the ESWT group (p=0.046).

Conclusion

Both treatment modalities are effective and not superior to each other in terms of disability and activity limitation reduction, although a greater improvement in the FFI pain and total scores can be achieved with the ESWT. Based on these findings, we recommend both non-invasive treatment methods to be used in the treatment of calcaneal spurs in the clinical practice.

Effects of adjuvant low-dye Kinesio taping, adjuvant sham taping, or extracorporeal shockwave therapy alone in plantar fasciitis: A randomised double-blind controlled trial

AIM

Extracorporeal shockwave therapy (ESWT) is known as one of the most effective treatment methods in plantar fasciitis (PF). Low-dye taping, which is the most preferred method of banding treatments, provides an analgesic effect by correcting biomechanics. It was aimed to compare the efficacy of adjuvant low-dye kinesio-taping (KT), sham-taping, or ESWT alone in PF.

METHODS

In this double-blind, sham-controlled study, 45 patients with PF were randomised into Group 3 (Group 1: ESWT plus low-dye KT, n = 15; Group 2: ESWT plus Sham-taping, n = 15; and Group 3: ESWT only, n = 15) five-session ESWT were administrated. KT was performed and changed every 1-week for the ESWT sessions in Groups 1 and 2. The main outcome measures were the visual analogue scale (VAS) change, the heel tenderness index (HTI), foot function index (FFI). The patients were evaluated at the beginning and end of the treatment and at the 4-week follow-up.

RESULTS

The demographic characteristics and baseline outcomes between groups were similar (P > .05). No significant difference was found between Groups 1 and 2, Groups 1 and 3 and Groups 2 and 3 with respect to VAS, HTI changes during the 4-week follow-up. VAS and HTI changes were observed in all three groups, there were no differences between groups. Repeated-measures ANOVA showed a significant interaction between the time and the groups in FFI-total (F_3.919  = 2.607; P = .043). For the FFI total, there was only a significant difference in favour of Group 1 when compared with Group 2 (P = .027).

CONCLUSIONS

Although low-dye KT in addition to ESWT was more effective on foot function improvement than additive sham-taping and ESWT alone, it did not provide a significant benefit on pain and heel tenderness because of PF.

CLINICAL TRIAL REGISTRATION NUMBER

The study was registered at the U.S. National Institutes of Health (ClinicalTrials.gov) (NCT03904966).

Determinants of Self-reported Health Outcomes in Adrenal Insufficiency: A Multisite Survey Study

CONTEXT

Current evidence on determinants of adverse health outcomes in patients with adrenal insufficiency (AI) is scarce, especially in regards to AI subtypes.

OBJECTIVE

To determine predictors of adverse outcomes in different subtypes of AI.

DESIGN AND SETTING

Cross-sectional survey study at 2 tertiary centers.

PARTICIPANTS

A total of 696 patients with AI: primary AI (PAI, 42%), secondary AI (SAI, 32%), and glucocorticoid-induced AI (GIAI, 26%).

INTERVENTION

Patient-centered questionnaire.

MAIN OUTCOME MEASURES

Patients' knowledge, self-management of AI, self-perceived health, and adverse outcomes.

RESULTS

The incidence rate of adrenal crisis was 24/100 patient-years with 44% experiencing at least 1 adrenal crisis since diagnosis (59% in PAI vs 31% in SAI vs 37% in GIAI, P < .0001). All patients described high degrees of discomfort with self-management and receiving prompt treatment. Patients with PAI were most likely to develop adrenal crises (adjusted OR 2.8, 95% CI 1.9-4.0) despite reporting better self-perceived health (adjusted OR 3.3, 95% CI 2.1-5.3), understanding of their diagnosis (89% vs 74-81% in other subtypes, P = .002), higher comfort with self-management (62% vs 52-61% in other sub types, P = .005), and higher likelihood to receive prompt treatment for adrenal crises in the emergency department (42% vs 19-30% in other subtypes, P < .0001).

CONCLUSIONS

Patients with AI reported high degrees of discomfort with self-management and treatment delays when presenting with adrenal crises. Despite better self-perceived health and understanding of diagnosis, patients with PAI experienced the highest frequency of adrenal crises. A multidimensional educational effort is needed for patients and providers to improve the outcomes of all subtypes of AI.

Autoregulated heavy slow resistance training combined with radial shockwave therapy for plantar heel pain: Protocol for a mixed-methods pilot randomised controlled trial

BACKGROUND

Plantar heel pain (PHP) is considered a tendinopathy and it affects up to 10% of the population. Both heavy slow resistance training (HSRT) and extracorporeal shockwave therapy (ESWT) have shown effectiveness for treating PHP in isolation. However, more comprehensive exercise protocols and progression methods are needed due to poor long-term outcomes, and better standardisation of ESWT protocols are required. Autoregulation of resistance training involves self-selecting exercise dosage based on individual factors. Although autoregulation has proven effective for strength gains in athletes, it has not been investigated in tendinopathy. Recent studies recommend that PHP should not be treated by one treatment intervention in isolation. However, there is a dearth of research investigating the feasibility and effectiveness of combined treatment interventions for PHP. Currently, no studies have investigated autoregulated HSRT combined with ESWT, despite their individual efficacy. The optimal treatment protocol for PHP is unknown, and there is a need to ascertain whether the addition of ESWT to autoregulated HSRT leads to better outcomes compared to either alone.

METHODS

A three-arm randomised controlled trial (RCT) comparing these groups would be the ideal way to investigate this question, with a pilot RCT testing trial procedures and process evaluation required prior to a definitive RCT. Patients expectations, feasibility and acceptability of combined ESWT and exercise for PHP also remain unknown. Therefore, the addition of qualitative interviews in a mixed-methods pilot RCT would help ascertain acceptability and help explain the intervention outcomes.

Long-term effect and prognostic factors of a low-dose radiotherapy of painful plantar calcaneal spurs : A retrospective unicenter study

PURPOSE

To estimate the long-term effect of low-dose radiotherapy of painful plantar calcaneal spurs, and to verify possible prognostic factors.

PATIENTS AND METHODS

In this retrospective unicenter study, electronic patient files of patients with painful plantar calcaneal spurs treated with low-dose radiotherapy between July 2009 and February 2020 were reviewed. The low-dose radiotherapy consisted of a total dose of 3.0 Gy given with a fraction dose of 0.5 Gy three times a week. The pain reduction was estimated using a patient questionnaire with a visual analogue scale. Kaplan-Meier statistics and Cox regression analysis were used for the statistical analysis.

RESULTS

Altogether, 864 heels of 666 patients were reviewed. The probability of an insufficient pain control 10 years after low-dose radiotherapy was 45.9% (95% confidence interval 39.4-52.4%) in the subset of patients with a minimum follow-up of 3 months (582 heels of 467 patients). Patients with an unsatisfactory pain reduction 3 months after low-dose radiotherapy were offered a re-irradiation. Forty percent of the patients who received a re-irradiation developed good pain reduction. Occurrence of an initial aggravation of pain during or within 3 months after low-dose radiotherapy (p = 0.005), and treatment of bilateral painful plantar calcaneal spurs (p = 0.008) were identified as significant unfavorable prognostic factors on univariate analysis. On multivariate analysis, the initial aggravation of pain remained as independent significant prognostic factor (p = 0.01). No clear radiation toxicity was observed.

CONCLUSIONS

Low-dose radiotherapy is a safe and effective treatment option for patients with painful plantar calcaneal spurs. An initial aggravation of pain during or within 3 months after radiotherapy was identified as unfavorable prognostic factor for the treatment outcome. Re-irradiation of patients with an unsatisfactory pain reduction after low-dose radiotherapy is effective and should be offered to patients.

Evaluation of Efficacy of Low-Level Laser Therapy

Introduction: Given the inconsistencies in the literature regarding laser performance in non-surgical treatments, this study investigated the available literature to determine the advantages and disadvantages of low-power lasers in treating non-surgical complications and diseases. Methods: Authentic information from articles was extracted and evaluated to assess low-power laser performance for non-surgical treatments. A systematic search of studies on low-level laser therapy (LLLT) for non-surgical treatments was conducted mainly in PubMed and google scholar articles. Results: Four categories of diseases, including brain-related diseases, skin-related diseases, cancers, and bone-related disorders, which were treated by LLLT were identified and introduced. The various types of LLLT regarding the studied diseases were discussed. Conclusion: Positive aspects of LLLT versus a few disadvantages of its application imply more investigation to find better and efficient new methods.

The Effects of Inhalation Aromatherapy on Postoperative Abdominal Pain: A Three-Arm Randomized Controlled Clinical Trial

PURPOSE

This study compares the effects of inhalation aromatherapy using essential oils of sweet orange and damask rose on postoperative abdominal pain.

DESIGN

A randomized three-arm controlled trial.

METHODS

In this randomized double-blinded, and parallel-group controlled trial, a total of 120 patients who underwent open abdominal surgeries were enrolled using a sequential sampling method. Participants were then randomly assigned to three groups of sweet orange, damask rose, and placebo (distilled water) using the permuted block randomization. When the patients regained full consciousness, a clean gauze impregnated with four drops of either distilled water or essential oils of sweet orange or damask rose were attached to the collar of the patients, and they were asked to inhale the aroma through normal breathing for 30 minutes. Abdominal pain severity was recorded using the visual analog scale at four time points including before the intervention (baseline) and 4, 8, and 12 hours after the intervention.

FINDINGS

Pain reduction after sweet orange inhalation was significantly greater than placebo (at 8 and 12 hours after the intervention) and damask rose (at 12 hours after the intervention). The differences in the mean score of pain severity between all before-and-after observations were statistically significant in the three groups, except in the placebo group between the baseline score of pain severity and the pain severity score at 4 hours after the intervention.

CONCLUSIONS

Inhalation aromatherapy using sweet orange seems to be more effective than the damask rose in reducing pain severity after open abdominal surgeries.

Effectiveness of combined shockwave therapy and plantar fascia stretching interventions in treating plantar heel pain: a systematic review and meta-analysis protocol

OBJECTIVE

The objective of this review is to synthesize the best available evidence on the effectiveness of interventions that have used a combination of extracorporeal shockwave therapy and plantar fascia-specific stretching to treat plantar heel pain compared to any other non-surgical intervention.

INTRODUCTION

Recent evidence suggests combining shockwave therapy and plantar fascia stretching may be more effective than other treatments for plantar heel pain. However, no systematic reviews have been conducted on the topic and optimal treatment protocols and clinical recommendations are lacking.

INCLUSION CRITERIA

Randomized controlled trials assessing the effectiveness of combined shockwave therapy and plantar stretching for plantar heel pain in adults will be included.

METHODS

The authors will search a wide range of sources to identify both published and unpublished studies via EBSCOhost, including, but not limited to MEDLINE, SPORTDiscus, CINAHL, Cochrane Central Register of Controlled Trials (CENTRAL), and Allied and Complementary Medicine Database (AMED). Studies published in a language other than English will only be considered if a translation is available. The JBI systematic review methodology will be followed when conducting the review. Data synthesis will be conducted using meta-analysis or narrative synthesis, where appropriate.

Taping for conditions of the musculoskeletal system: an evidence map review

Background

Taping is a common treatment modality used by many rehabilitation providers. Several types of tapes and taping methods are used in the treatment of musculoskeletal dysfunction and pain.

Purpose

To summarize and map the evidence related to taping methods used for various joints and conditions of the musculoskeletal system, and to provide clinicians and researchers with a user-friendly reference with organized evidence tables.

Data sources

The PEDro, CINAHL, Cochrane Database of Systematic Reviews, Cochrane Central Register for Controlled Trials, PubMed, and PROSPERO databases were searched from inception through October 31, 2019.

Study selection

Eligible studies were selected by two independent reviewers and included either systematic reviews (SRs) or randomized controlled trials (RCTs) and included a musculoskeletal complaint using a clinical outcome measure.

Data extraction

Data was extracted by two investigators independently. Risk of bias and quality were assessed using A MeaSurement Tool to Assess systematic Reviews (AMSTAR) for SRs or the Physiotherapy Evidence Database (PEDro) scale for RCTs. The protocol was registered with PROSPERO (CRD42019122857).

Data synthesis

Twenty-five musculoskeletal conditions were summarized from forty-one SRs and 127 RCTs. There were 6 SRs and 49 RCTs for spinal conditions. Kinesio tape was the most common type of tape considered. Four evidence tables representing the synthesized SRs and RCTs were produced and organized by body region per condition.

Limitations

Inclusion of only English language studies. Also, the heterogeneous nature of the included studies prevented a meta-analysis.

Conclusions

There is mixed quality evidence of effectiveness for the different types of taping methods for different body regions and conditions. All of the SRs and RCTs found during our search of the taping literature have been organized into a series of appendices. A synthesis of the results have been placed in evidence tables that may serve as a useful guide to clinicians and researchers.

Endoscopic Plantar Fascia Release versus Cryosurgery for the Treatment of Chronic Plantar Fasciitis: A Prospective Randomized Study

BACKGROUND

In a prospective randomized study, we compared two different surgical techniques used in plantar fasciitis surgery.

METHODS

Forty-eight patients diagnosed as having plantar fasciitis and treated for at least 6 months with no response to conservative modalities were included in this study. The patients were randomly assigned to receive endoscopic plantar fascia release (EPFR) or cryosurgery (CS). Patients were evaluated using the American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale (AOFAS-AHS) as a primary outcome measurement at baseline and 3 weeks and 3, 6, and 12 months after surgery. At the final follow-up visit, the Roles-Maudsley score was used to determine patient satisfaction.

RESULTS

Five patients did not complete the 1-year follow-up examination (one in the EPFR group and four in the CS group). Thus, the study group included 43 patients. Although both groups showed significant improvement at the final evaluation, the patients in the EPFR group had significantly better AOFAS-AHS scores at 3 months. The success rate (Roles-Maudsley scores of excellent and good) in the EPFR group at 12 months was 87% and in the CS group was 65%.

CONCLUSIONS

Both EPFR and CS were associated with statistically significant improvements at 1-year follow-up. At 3-month follow-up, EPFR was associated with better results and a higher patient satisfaction rate compared with CS.

Association between trigger points in hamstring, posterior leg, foot muscles and plantar fasciopathy: A cross- sectional study

BACKROUND

Plantar Fasciopathy (PF) is soreness or irritability experienced underneath infero-medial aspect of the heel. It is a multifactorial disorder where myofascial involvement also seems to be associated with it, in which, muscles of posterior thigh, leg and foot muscles are affected. Trigger points in these muscles may interfere with biomechanics and normal functioning of the lower limb.

OBJECTIVE

To find an association between trigger points of the posterior thigh, leg and foot muscles and plantar fasciopathy.

STUDY DESIGN

A cross sectional study.

METHODS

100 patients with plantar fasciopathy who fulfilled inclusion criteria were included in this study. They were examined for trigger points by manual palpation in posterior thigh, leg and foot muscles. Totally 15 muscles were examined on both affected and unaffected side.

RESULTS

Results showed that myofascial trigger points were more prevalent in medial gastrocnemius (98%, Chi-square: 110.07, p < 0.05, Phi-0.74), quadratus plantae (83%, Chi-square:126.96, p < 0.05, Phi- 0.79), soleus (69%, Chi-square: 28.88, p < 0.05, Phi-0.38), tibialis posterior (46%, Chi-square 41.98 p<0.05%, Phi-0.50), abductor hallucis (42%, Chi-square: 43.61 p<0.05% Phi-0.46), flexor halluces longus (41%, Chisquare: 39.25, p < 0.05, Phi-0.44) than other muscles on the affected side. Whereas, on the unaffected side, trigger points were more prevalent among peroneus longus (50%, Chi-square: 26.14, p < 0.05, Phi-0.36) followed by medial gastrocnemius (26%, Chisquare: 110.07, p < 0.05, Phi-0.74).

CONCLUSION

Plantar fasciopathy is strongly associated with trigger points of medial gastrocnemius, quadratus plantae followed by soleus, tibialis posterior, abductor hallucis and flexor hallucis longus.

The effect of high-intensity versus low-level laser therapy in the management of plantar fasciitis: randomized participant blind controlled trial

Objectives:

To evaluate and compare the efficacy of high-intensity laser therapy (HILT) and low-level laser therapy (LLLT) for plantar fasciitis.

Design:

A participant blind randomized controlled trial with parallel group design and an active comparator with follow-up at four weeks.

Settings:

Outpatient, University hospital.

Subjects:

Unilateral plantar fasciitis participants (n = 102) were randomly assigned into two groups. Recruitment period was from January 2017 to April 2019.

Interventions:

Interventions included eight sessions of laser therapy over three weeks and single session of patient education. The HILT group (n = 51) received HILT and the LLLT group (n = 51) received LLLT.

Main measures:

Primary outcomes: visual analogue scale; secondary outcomes: pressure algometry, sonography of plantar fascia thickness (time frame: baseline to three-week and four-week follow-up) and numeric rating scale (0%–100%) for opinion of participants on effect of treatment (time frame: three weeks). Data presented: mean (SD) or n (%).

Results:

There was no statistically significant difference between the groups according to visual analogue scale (pain in general reduction in three weeks: 2.57(3.45) vs. 2.88(3.28) cm), pressure algometry (pain threshold difference between healthy and affected heel reduction in three weeks: 1.80(6.39) vs. 1.77(2.85) kg) and sonography measurements (plantar fascia thickness difference between healthy and affected heel reduction in three weeks: 0.19(0.56) vs. 0.30(0.57) mm). There was a statistically significant difference between the groups in participants’ opinion in favor to HILT group (efficacy of treatment better than 50%: 26(51%) vs. 37(73%)).

Conclusion:

No statistically significant difference between groups was observed.

Foot exercise plus education versus wait and see for the treatment of plantar heel pain (FEET trial): a protocol for a feasibility study

Background

Plantar heel pain (PHP) is present in a wide range of individuals and creates significant burden to quality of life and participation in physical activity. The high recurrence rates and persistence of PHP suggests current management options may not address all potentially modifiable factors associated with the condition. Reports of intrinsic foot muscle (IFM) atrophy in individuals with PHP, together with biomechanical evidence of their important contribution to optimal foot function, suggests that an intervention focused on IFM training may be beneficial in managing PHP. We will test the feasibility of a prospective, assessor-blinded, parallel-group, randomised clinical trial that compares foot exercise plus education to brief advice in individuals with PHP.

Methods

Twenty participants with PHP will be randomly allocated to one of two groups for a 12-week intervention period: (i) foot exercise plus education, or (ii) brief advice. The foot exercise plus education group will attend eight sessions with a physiotherapist and receive detailed education on self-management strategies as well as a progressive exercise program for the IFMs. The brief advice group will attend one session with a physiotherapist and receive brief information about self-management strategies and reassurance. Outcome measures will be obtained at baseline and the primary end-point of 12 weeks. Primary outcomes will be the feasibility of conducting a full-scale randomised clinical trial (RCT), and the credibility and acceptability of the foot exercise plus education intervention. Secondary outcomes will explore treatment effects, which will consist of pain, physical function, physical activity level, pain self-efficacy, perceived treatment effect, magnetic resonance and ultrasound image measurement of IFM morphology, ultrasound imaging measurement of plantar fascia thickness, IFM motor performance, foot posture, foot mobility, ankle dorsiflexion range of motion, toe flexor and plantar flexor strength/endurance.

Discussion

To reduce the burden of PHP on individuals and society, there is a need to establish effective treatments that are feasible and accepted by patients and health professionals. This trial will be the first to evaluate the feasibility of conducting a full-scale RCT, as well as the credibility, acceptability, and treatment effects, of education and foot exercise for PHP. The findings of this study will inform the development of a full-scale RCT.

Trial registration

The trial protocol was prospectively registered with the Australia and New Zealand Clinical Trial Registry (ACTRN12619000987167) on 11th July 2019.

[Comparison between extracorporeal shockwave therapy and radial pressure wave therapy in plantar fasciitis]

OBJECTIVE

Plantar fasciitis is a common cause of heel pain. The aetiology of this condition remains unclear. Patients typically have pain upon palpation of the medial plantar calcaneal region. Extracorporeal shockwave therapy has shown favourable outcomes in various studies. The aim of this study was to compare the effect of focused extracorporeal shockwave therapy with radial pressure wave therapy.

PATIENTS AND METHODS

Seventy-nine non-randomised patients diagnosed with plantar fasciitis were included between January 2017 and June 2018. Patients from the Arnau de Vilanova Hospital in Valencia were treated with focused extracorporeal shockwave therapy, and patients from Llíria Hospital with radial pressure wave therapy. Measured outcome variables were: visual analog scale; ultrasonographic measurement of plantar fascia thickness; self-reported foot-specific pain and disability using the Foot Function Index; self-reported health-related quality of life using the Euroqol-5D; self-reported pain and limitations of activity using the Roles & Maudsley Scale.

RESULTS

At inclusion, the 2groups showed no significant differences in demographic or clinical characteristics. Three months after treatment completion, both groups showed improvement in all outcome variables, without statistically significant differences between the 2groups. No adverse effects or complications were observed.

CONCLUSIONS

Both extracorporeal shockwave therapy and radial pressure wave therapy are effective treatments for plantar fasciitis.

Effects of insoles adapted in flip-flop sandals in people with plantar fasciopathy: a randomized, double-blind clinical, controlled study

OBJECTIVE

To evaluate the effects of insoles adapted into flip-flop sandals on pain and function in individuals with plantar fasciopathy (PF).

DESIGN

Randomized, double-blind controlled study.

SETTING

Physiotherapy clinic of the Faculty of Health Sciences of Trairi, Federal University of Rio Grande do Norte, Santa Cruz, Brazil.

SUBJECTS

Sixty-six patients of both genders with PF were randomized into two groups: sandal insole group (SI; n = 34), which received a pair of custom flip-flop sandals with insoles covered with smooth synthetic leather; and plain sandal group (PS; n = 32), which received an identical pair of flip-flop sandals, but without the insoles.

INTERVENTIONS

Patients were instructed to wear the flip-flops for 12 weeks for at least 4 hours/day.

MAIN MEASURES

Pain (visual analogue scale-VAS) in the morning and at the end of the day were considered primary outcomes. Function (Foot Function Index-FFI and Foot and Ankle Ability Measure-FAAM) and functional capacity (6-minute walk test-6MWT) were considered secondary outcomes. The outcomes were evaluated at baseline and immediately after the intervention by a blind assessor.

RESULTS

Between-group differences were observed in terms of morning pain (mean difference (MD) = -1.82 cm; 95% confidence interval (CI) = -3.3 to -0.3; P = 0.016) and function (MD = -0.10; 95% CI = -0.19 to -0.01; P = 0.023) after the interventions with the SI group showing superior improvements in comparison to the PS group.

CONCLUSION

The use of insoles adapted in flip-flop sandals for 12 weeks was effective at improving pain and function in individuals with PF.

Effectiveness of Mechanical Treatment for Plantar Fasciitis: A Systematic Review

CONTEXT

Plantar fasciitis is one of the most common foot injuries. Several mechanical treatment options, including shoe inserts, ankle-foot orthoses, tape, and shoes are used to relieve the symptoms of plantar fasciitis.

OBJECTIVES

To investigate the effectiveness of mechanical treatment in the management of plantar fasciitis.

EVIDENCE ACQUISITION

The review was reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement. A systematic search was performed in PubMed, CINAHL, Embase, and Cochrane up to March 8, 2018. Two independent reviewers screened eligible articles and assessed risk of bias using the Cochrane Collaboration's risk of bias tool.

EVIDENCE SYNTHESIS

A total of 43 articles were included in the study, evaluating 2837 patients. Comparisons were made between no treatment and treatment with insoles, tape, ankle-foot orthoses including night splints and shoes. Tape, ankle-foot orthoses, and shoes were also compared with insoles. Follow-up ranged from 3 to 5 days to 12 months. Cointerventions were present in 26 studies.

CONCLUSIONS

Mechanical treatment can be beneficial in relieving symptoms related to plantar fasciitis. Contoured full-length insoles are more effective in relieving symptoms related to plantar fasciitis than heel cups. Combining night splints or rocker shoes with insoles enhances improvement in pain relief and function compared with rocker shoes, night splints, or insoles alone. Taping is an effective short-term treatment. Future studies should aim to improve methodological quality using blinding, allocation concealment, avoid cointerventions, and use biomechanical measures of treatment effects.

Use of 3D-Printed Heel Support Insoles Based on Arch Lift Improves Foot Pressure Distribution in Healthy People

Background

3D-printed insoles are widely used. This study was conducted to test a customized three-dimensional (3D)-printed heel support insole based on arch lift and to investigate whether the pressure distribution on the sole was improved while maintaining foot function.

Material/Methods

The design was based on a 3D plantar contour scanning modeling technique. Thirty healthy male participants walked along a 10-m track under 3 self-controlled interventions. A customized 3D-printed heel support insole based on arch lift was inserted into the socks for the experimental condition A. For condition B, a customized 3D-printed heel-supporting insole was inserted into the socks, and a standardized pre-made heel-supporting insole was inserted into the socks as a control (condition C). We used the Footscan^® pressure plate to measure the plantar parameters in the forefoot contact and foot flange phases in each condition.

Results

Compared with condition B and the control condition, the peak pressure under the heel was significantly lower in condition A (P<0.05), and the peak pressure in the midfoot region was not significantly increased (P>0.05).

Conclusions

The biomechanical properties of the customized 3D-printed heel support are better than those of the traditional heel support insole, especially when there is a need for an additional increase in heel height. Patients do not decrease midfoot motion function while using this customized insole.

[Differential diagnosis of heel pain]

"Heel pain" describes a very common reason for foot orthopedic consultation and the further differential diagnostic investigation is crucial for the choice of correct treatment. In the treatment of frequent underlying diseases, such as plantar fasciitis or insertional tendinopathy of the Achilles tendon, a variety of modern strategies are available. Rarer diseases, such as tumors or nerve entrapment syndromes must be delineated and correctly classified. This article provides the current state of the diagnostics and treatment of the most common entities of heel pathologies.
