Extracorporeal shock wave therapy versus corticosteroid injection for chronic plantar fasciitis: A protocol of randomized controlled trial

BACKGROUND

The outcomes of corticosteroid injection (CSI) and extracorporeal shock wave therapy (ESWT) as primary treatment of plantar fasciitis have been debated. This study was conducted to compare and evaluate the therapeutic effects of ultrasound-guided CSI versus medium frequency ESWT in the treatment of plantar fasciitis among Chinese population.

METHODS

This study was a single-center, randomized, and double-blinded trial. The study protocol was approved by local ethics committee board and subsequently registered in Research Registry. Eighty patients with unilateral plantar fasciitis were randomized to receive either ESWT (3 times once per week) (n = 40) or CSI treatment (a single 1-mL dose of betamethasone sodium plus 0.5 mL of prilocaine under ultrasound guidance by injection into the plantar fascia) (n = 40). The primary outcome measures were visual analog scale and Foot Function Index scores. Secondary outcome measures included the heel tenderness index score and plantar fascia thickness as obtained by ultrasound examination. All of the assessments were performed at baseline and 1, 3, and 6 months after treatment.

RESULTS

This is a randomized controlled trial evaluating the efficacy of CSI versus ESWT in the treatment of plantar fasciitis. This study has limited inclusion and exclusion criteria and a well-controlled intervention.

CONCLUSIONS

The results of this trial will provide more evidence on which method can better treat plantar fasciitis.

The effects of shockwave therapy on musculoskeletal conditions based on changes in imaging: a systematic review and meta-analysis with meta-regression

BACKGROUND

Shockwave therapy (SWT) is a commonly used intervention for a number of musculoskeletal conditions with varying clinical outcomes. However, the capacity of SWT to influence pathophysiological processes and the morphology of affected tissues remains unclear. The objective of the current review is to evaluate changes in imaging outcomes of musculoskeletal conditions following SWT.

METHODS

A comprehensive search of Medline, Embase, Cochrane Controlled Trials Register, CINAHL and SportDiscus was conducted from inception to October 2018. Prospective clinical trials evaluating the effectiveness of SWT based on changes in imaging outcomes were eligible for inclusion. Articles were evaluated independently for risk of bias using the Cochrane Risk of Bias list and the Methodological Index for Non-Randomized Studies. Random-effects meta-analysis and meta-regression with a priori determined covariates was conducted for each condition to determine potential predictors of SWT effects.

RESULTS

Sixty-three studies were included, with data from 27 studies available for effect size pooling. Meta-analyses and meta-regression on imaging outcomes were performed for rotator cuff calcific tendinitis (n = 11), plantar fasciitis (n = 7) and osteonecrosis of the femoral head (n = 9). There was an overall reduction in the size of measured lesion following SWT (MD 8.44 mm (95%CI -4.30, 12.57), p < 0.001) for calcium deposit diameter, (MD 0.92 mm (95%CI -0.03, 1.81), p = 0.04) for plantar fascia thickness and (MD 4.84% (95%CI -0.06, 9.75), p = 0.05) for lesion size in femoral head osteonecrosis. Meta-regression showed no influence of SWT dosage parameters, however, baseline lesion size was an independent predictor for changes in imaging outcomes.

CONCLUSIONS

SWT altered the morphology of musculoskeletal conditions, potentially reflecting changes in underlying pathophysiological processes. The parameters of SWT dosage are not significant predictors of changes in imaging outcomes. Lack of adequate reporting of imaging outcomes limited the conclusions that could be drawn from the current review. Registration number: PROSPERO CRD42018091140.

Shock-wave therapy improved outcome with plantar fasciitis: a meta-analysis of randomized controlled trials

BACKGROUND

Shock-wave therapy (SWT) has been widely applied and proven to be an effective treatment in ameliorating symptoms of plantar fasciitis (PF). Ultrasound therapy (UT) is another common treatment of PF, and several researches have documented its advantages when compared to corticosteroid injection. Despite this, few studies have focused on comparing the use of SWT and UT in the treatment of PF. The purpose of our meta-analysis is to evaluate whether SWT is better than UT in managing PF, both in terms of ameliorating pain and improving functionality.

METHODS

A systematic search of the literature was conducted to identify relevant articles that were published in Pubmed, Medline, Embase, the Cochrane Library, SpringerLink, Clinical Trials.gov and OVID from the databases' inception to October 2018. All studies comparing the efficacy of SWT and UT in terms of pain levels and functionality improvement were included. Data on the two primary outcomes were collected and analyzed using the Review Manager 5.3.

RESULTS

Five studies were included in the current meta-analysis. A significant difference in VAS score (MD = - 13.14, Cl - 14.07 to - 12.75 P < 0.00001, I² = 100%) was noted between the SWT group and the UT group. No significant difference was seen in the AOFAS (MD = 3.19, Cl - 1.72 to 8.10 P = 0.20, I² = 100%); FFI or PFPS score was not found significant difference either (SMD = - 1.17, Cl - 4.45 to 2.10 P = 0.48, I² = 96%).

CONCLUSIONS

The results from this meta-analysis highlight the effectiveness of both SWT and UT in the treatment of PF. Although inter-group differences were not significant, the VAS score was better improved in the SWT group, suggesting that SWT may be a superior alternative for the treatment of PF.

Elastosonographic evaluation after extracorporeal shockwave treatment in plantar fasciopathy

AIM

To assess the ultrasound features in patients with plantar fasciopathy before and after extracorporeal shock waves therapy (ESWT), using conventional grey-scale imaging and both strain (SE) and shear wave (SWE) elastosonographic evaluation.

MATERIAL AND METHOD

Consecutive patients of both sexes attending our outpatient's clinic, with diagnosis of unilateral plantar fasciopathy, were enrolled. Patients were treated with 3 sessions of ESWT once a week, and underwent clinical and ultrasound evaluation at baseline and at one and three months after treatment. Roles and Maudsley score (RM), visual analog scale (VAS) and 17-Italian Foot Function Index (FFI), were used to assess pain and functional improvement.

RESULTS

Twenty patients (11 female and 9 male) were enrolled in the study. Contralateral asymptomatic healthy plantar fascia was used as a control. At baseline, SWE velocity (SWEv) showed statistically significant difference between affected 3.8 (1.5; 5.1) m/s and healthy side 4.7 (4.07; 7.04) m/s, (p=0.006); no significant difference was found for strain ratio values (p=0.656). SWEv post hoc test results showed a significant difference from baseline 3.8 (1.5-5.1) m/s and three month 5.23 (4.55-6.74) m/s follow up visit (p=0.003). Significant statistical negative correlation was found between the SWEv and VAS (p=0.001) and positive correlation between the SWEv and FFI (p=0.012).

CONCLUSION

SWE was effective in assessing plantar fascia elasticity and its alteration in fasciopathy. Furthermore, on the basis of the correlation with pain and functional scales, this technique appears to be a useful additional technique to conventional ultrasound for monitoring the efficacy of treatment.

Plantar Fasciitis

Plantar fasciitis is a common problem that one in 10 people will experience in their lifetime. Plantar fasciopathy is an appropriate descriptor because the condition is not inflammatory. Risk factors include limited ankle dorsiflexion, increased body mass index, and standing for prolonged periods of time. Plantar fasciitis is common in runners but can also affect sedentary people. With proper treatment, 80% of patients with plantar fasciitis improve within 12 months. Plantar fasciitis is predominantly a clinical diagnosis. Symptoms are stabbing, nonradiating pain first thing in the morning in the proximal medioplantar surface of the foot; the pain becomes worse at the end of the day. Physical examination findings are often limited to tenderness to palpation of the proximal plantar fascial insertion at the anteromedial calcaneus. Ultrasonography is a reasonable and inexpensive diagnostic tool for patients with pain that persists beyond three months despite treatment. Treatment should start with stretching of the plantar fascia, ice massage, and nonsteroidal anti-inflammatory drugs. Many standard treatments such as night splints and orthoses have not shown benefit over placebo. Recalcitrant plantar fasciitis can be treated with injections, extracorporeal shock wave therapy, or surgical procedures, although evidence is lacking. Endoscopic fasciotomy may be required in patients who continue to have pain that limits activity and function despite exhausting nonoperative treatment options.

The effects of hip strengthening exercises in a patient with plantar fasciitis: A case report

RATIONALE

Plantar fasciitis is a common cause of foot pain presenting with morning stiffness and plantar area pain. This case study is to optimize the management in patient with plantar fasciitis accompanied by apparent high-arch foot.

PATIENT CONCERNS

A 55-year-old women presented with plantar fasciitis accompanied by apparent high-arch foot. The pain presents for the heel and pelvic areas with long-distance walking.

DIAGNOSES

She was diagnosed with plantar fasciitis accompanied by apparent high-arch foot for physical examination and plain radiographs. In muscle performance and dynamic postural stability tests, indicated the muscle weakness and postural instability.

INTERVENTIONS

The patient was treated with manual therapy such as joint and soft tissue mobilization interventions including plantar fascia and gastrocnemius stretching, but the heel and pelvic pain were aggravated during long-distance walking. After hip strengthening exercises, the heel and pelvic pain significantly improved.

OUTCOMES

The 3-month follow-up revealed that the heel and pelvic pain did not occur in the long-distance walking, and there was no pain and discomfort at one year follow-up.

LESSONS

To optimize the management in patient with plantar fasciitis accompanied by apparent high-arch deformity, clinicians should try to identify the hip abductor muscles weakness, and therapists should consider incorporating hip strengthening exercises.

Electroacupuncture versus manual acupuncture in the treatment of plantar heel pain syndrome: study protocol for an upcoming randomised controlled trial

INTRODUCTION

Plantar heel pain syndrome(PHPS) is a common cause of heel pain. It may worsen a patient's quality of life, and potentially lead to knee, hip or lower back problems. Previous studies have shown that electroacupuncture (EA) and manual acupuncture (MA) are effective treatments for relieving pain in patients with PHPS. However, little evidence supports the use of one intervention over the other.

METHODS AND ANALYSIS

A total of 92 patients diagnosed with PHPS will be recruited and randomly assigned to an EA group or an MA group at a ratio of 1:1. Patients in both groups will receive a 30 min acupuncture treatment (three times per week) for a total of 12 sessions over 4 weeks. The primary outcome will be the proportion of patients with at least 50% reduction from baseline in the worst pain intensity measured by visual analogue scale (0-100, higher scores signify worse pain) at first steps in the morning after 4-week treatment. The secondary outcomes will include change in worst pain intensity at first steps in the morning, change in mean pain intensity at first steps in the morning, change in worst pain intensity during the day, change in mean pain intensity during the day, change in the pressure pain threshold, change in ankle-dorsiflexion range of motion, change in Foot and Ankle Ability Measure total score and subscale scores, patients' global improvement assessment, patients' expectations for acupuncture and safety evaluation. We will perform all statistical analysis following the intention-to-treat principle.

ETHICS AND DISSEMINATION

The study has been approved by our ethics review board (Protocol Approval No. 2018-010-KY). The study findings will be disseminated through presentation at a high-impact medical journal, with online access. We also to plan to present it in select conferences and scientific meetings.

[Short-Term Outcomes of Endoscopic Treatment of Inferior Calcar Calcanei in Patients with Plantar Fasciitis]

PURPOSE OF THE STUDY The prospective study evaluates the short-term outcomes of endoscopic treatment of calcar calcanei in patients who underwent unsuccessfully more than 6 months of conservative therapy. MATERIAL AND METHODS Our study included 34 patients with refractory plantar fasciitis, in whom endoscopic treatment of inferior calcar calcanei with partial plantar fasciotomy was performed in the period from 01. 01. 2009 to 31. 07. 2015. The assessed parameters were the following: level of function, pain relief and patient satisfaction on the FAAM (Foot and Ankle Ability Measure) score and VAS (Visual Analog Scale) score with the minimum follow-up of 1 year. RESULTS A marked increase in the FAAM score from 39.2 preoperatively to 94.0 one year after the surgery and also a major pain relief on the VAS score from the initial 8 to the median 0 were observed. In total, 79.4% of patients were symptom-free one year after the surgery. The recurrence of calcar calcanei or ossification was seen on the radiograph taken one year after the surgery in 8 patients (23.5 %). DISCUSSION In our opinion, the most important outcome of our study is the considerable reduction in pain postoperatively (the median VAS score declined from 8 to 0 one year after the surgery) and concurrently a notable increase in the FAAM score (from 39.2 preoperatively to 94.0 one year after the surgery). Similar results of endoscopic partial fasciotomy were achieved also by some other authors. Therefore, this method can be considered validated. It has also been proven that the correlation between the calcar calcanei recurrence, or a higher BMI and recurrence of symptoms postoperatively is insignificant. CONCLUSIONS The endoscopic treatment of inferior calcar calcanei and plantar fasciotomy with denervation of fascial attachment is a fast, minimally invasive and safe method which brings very satisfactory results in the treatment of refractory plantar fasciitis. It is evidenced by subjective patient satisfaction, great function improvement, considerable pain relief after the surgery together with a minimum incidence of complications.

Clinical effects of extracorporeal shock-wave therapy and ultrasound-guided local corticosteroid injections for plantar fasciitis in adults: A meta-analysis of randomized controlled trials

BACKGROUND

The argument on whether extracorporeal shock-wave therapy (ESWT) and corticosteroid injections (CSIs) exert an equivalent pain control or which is the better treatment for plantar fasciitis (PF) in adults remains to be resolved. It is important and necessary to conduct a meta-analysis to make a relatively more credible and overall assessment about which treatment method performs better pain control in treatment of PF in adults.

METHODS

From the inception to July 2018, the Embase, PubMed, Web of Science, and Cochrane Library electronic databases were searched for all relevant studies. Only randomized controlled trials (RCTs) focusing on comparing ESWT and CSI therapies in PF cases in adults were included. The primary outcome measure was visual analog scale (VAS) reduction, whereas the secondary outcomes included treatment success rate, recurrence rate, function scores, and adverse events.

RESULTS

Nine RCTs involving 658 cases were included in this meta-analysis. In the present study, meta-analysis showed that high-intensity ESWT had superior pain relief and success rates relative to the CSI group within 3 months, but the ESWT with low intensity was slightly inferior to CSI for efficacy within 3 months. In addition, patients with CSI may tend to increase the need for the analgesic and more adverse events may be associated with the ESWT. However, the ESWT and CSI present similar recurrent rate and functional outcomes.

CONCLUSION

Our analysis showed that the pain relief and success rates were related to energy intensity levels, with the high-intensity ESWT had the highest probability of being the best treatment within 3 months, followed by CSI, and low-intensity ESWT. More high-quality RCTs with long-term follow-up time are needed to further compare the differences of CSI and ESWT for adults with PF.

Electrical dry needling as an adjunct to exercise, manual therapy and ultrasound for plantar fasciitis: A multi-center randomized clinical trial

Study Design

Randomized, single-blinded, multi-center, parallel-group trial.

Objectives

To compare the effects of adding electrical dry needling into a program of manual therapy, exercise and ultrasound on pain, function and related-disability in individuals with plantar fasciitis (PF).

Background

The isolated application of electrical dry needling, manual therapy, exercise, and ultrasound has been found to be effective for PF. However, no previous study has investigated the combined effect of these interventions in this population.

Methods

One hundred and eleven participants (n = 111) with plantar fasciitis were randomized to receive electrical dry needling, manual therapy, exercise and ultrasound (n = 58) or manual therapy, exercise and ultrasound (n = 53). The primary outcome was first-step pain in the morning as measured by the Numeric Pain Rating Scale (NPRS). Secondary outcomes included resting foot pain (NPRS), pain during activity (NPRS), the Lower Extremity Functional Scale (LEFS), the Foot Functional Index (FFI), medication intake, and the Global Rating of Change (GROC). The treatment period was 4 weeks with follow-up assessments at 1 week, 4 weeks, and 3 months after the first treatment session. Both groups received 6 sessions of impairment-based manual therapy directed to the lower limb, self-stretching of the plantar fascia and the Achilles tendon, strengthening exercises for the intrinsic muscles of the foot, and therapeutic ultrasound. In addition, the dry needling group also received 6 sessions of electrical dry needling using a standardized 8-point protocol for 20 minutes. The primary aim was examined with a 2-way mixed-model analysis of covariance (ANCOVA) with treatment group as the between-subjects variable and time as the within-subjects variable after adjusting for baseline outcomes.

Results

The 2X4 ANCOVA revealed that individuals with PF who received electrical dry needling, manual therapy, exercise and ultrasound experienced significantly greater improvements in first-step morning pain (F = 22.021; P<0.001), resting foot pain (F = 23.931; P<0.001), pain during activity (F = 7.629; P = 0.007), LEFS (F = 13.081; P<0.001), FFI Pain Subscale (F = 13.547; P<0.001), FFI Disability Subscale (F = 8.746; P = 0.004), and FFI Total Score (F = 10.65; P<0.001) than those who received manual therapy, exercise and ultrasound at 3 months. No differences in FFI Activity Limitation Subscale (F = 2.687; P = 0.104) were observed. Significantly (X² = 9.512; P = 0.023) more patients in the electrical dry needling group completely stopped taking medication for their pain compared to the manual therapy, exercise and ultrasound group at 3 months. Based on the cutoff score of ≥+5 on the GROC, significantly (X² = 45.582; P<0.001) more patients within the electrical dry needling group (n = 45, 78%) achieved a successful outcome compared to the manual therapy, exercise and ultrasound group (n = 11, 21%). Effect sizes ranged from medium to large (0.53<SMD<0.85) at 3 months in favor of the electrical dry needling group.

Conclusion

The inclusion of electrical dry needling into a program of manual therapy, exercise and ultrasound was more effective for improving pain, function and related-disability than the application of manual therapy, exercise and ultrasound alone in individuals with PF at mid-term (3 months).

Comparative effectiveness of extracorporeal shock wave, ultrasound, low-level laser therapy, noninvasive interactive neurostimulation, and pulsed radiofrequency treatment for treating plantar fasciitis: A systematic review and network meta-analysis

BACKGROUND

Plantar fasciitis is one of the most common causes of adult heel pain. The aim of this study is to comprehensively compare the effectiveness of various therapies for plantar fasciitis using network meta-analysis.

METHODS

Studies were comprehensively searched on Embase, MEDLINE via PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), and the Physiotherapy Evidence Database (PEDro) up to December 4, 2017. Randomized controlled trials that used extracorporeal shock wave therapy, ultrasound, ultrasound-guided pulsed radiofrequency treatment (UG-PRF), intracorporeal pneumatic shock therapy (IPST), low-level laser therapy (LLLT), and noninvasive interactive neurostimulation (NIN) for the treatment of plantar fasciitis were included. The primary outcome is change in pain relief. Risk of bias was assessed using the Cochrane risk of bias tool. Quality assessment was performed using the GRADE system.

RESULTS

Nineteen trials with 1676 patients with plantar fasciitis plantar fasciitis were included. In the pair-wise meta-analysis, radial extracorporeal shock wave therapy (RSW), LLLT, and IPST showed a significant pooled reduction in the visual analogue scale (VAS) compared with placebo at 0 to 6 weeks [mean difference (MD) = 6.60, 95% confidence interval (CI): (6.04, -7.16); MD = 2.34, 95% CI: (1.60, 3.08); MD = 2.24, 95% CI: (1.44, 3.04), respectively]. Compared with placebo, UG-PRF [MD = 2.31, 95% CI: (1.26, 3.36)] and high-intensity focused extracorporeal shock wave (H-FSW) [MD = 0.82, 95% CI: (0.20, 1.45)] showed superior pain-relieving effects at 2 to 4 months; UG-PRF [MD = 1.11, 95% CI: (0.07, 2.15)] and IPST [MD = 4.92, 95% CI: (4.11, 5.73)] showed superior effects at 6 to 12 months. In the network meta-analysis, only RSW induced significant pain reduction compared with placebo at 0 to 6 weeks [MD = 3.67, 95% CI: (0.31, 6.9)]. No significant differences were found for the 2 to 4-month and 6 to 12-month periods because of the wide 95% CIs.

CONCLUSIONS

We recommend treating plantar fasciitis with RSW. The commonly used ultrasound and focused extracorporeal shock wave (FSW) therapies can be considered as alternative treatment candidates. IPST, NIN, and LLLT may potentially be better alternatives, although their superiority should be confirmed by additional comprehensive evidence.PROSPERO registration number: PROSPERO (CRD42015017353).

Common Foot Problems: Over-the-Counter Treatments and Home Care

Most foot disorders do not require podiatry referral or complex interventions. After the clinical diagnosis is made, these conditions can typically be managed with over-the-counter (OTC) and home remedies, with guidance from the primary care physician. Stretching and strengthening exercises, along with the use of heel cups, resolve most plantar fasciitis cases and are at least as effective as nonsteroidal anti-inflammatory drugs or steroid injections. Hallux rigidus is best managed with a hard-soled shoe or rigid insert that relieves pain by restricting motion across the metatarsophalangeal joint. Hallux valgus responds to use of wide toe box shoes, and surgery is not clearly beneficial beyond one year. Plantar warts can be treated effectively at home with OTC salicylic acid and cryotherapy topical agents, which have equal effectiveness to liquid nitrogen. In patients with corns and calluses, OTC topical salicylic acid has short-term benefits, and pads and inserts that more evenly redistribute contact forces have long-term benefits. Inserts are commonly recommended to redistribute forefoot pressure and relieve pain. Several OTC preparations are available for the treatment of tinea pedis, with topical allylamines being the most effective. Although OTC topical treatments have been widely used for onychomycosis, they have poor long-term cure rates compared with prescription oral medications.

Effects of platelet-rich plasma in the treatment of plantar fasciitis: A meta-analysis of randomized controlled trials

BACKGROUND

Plantar fasciitis is a common cause of heel pain, which often results in significant morbidity. There have been several treatment options that are used for plantar fasciitis, including nonsteroidal anti-inflammatory drugs, orthoses, physical therapy, and steroid injections.

OBJECTIVES

The aim of this meta-analysis was to compare the effects of platelet-rich plasma (PRP) and other treatments in patients with plantar fasciitis.

SEARCH METHODS

Medline, Web of Science, and Embase were systematically searched to identify relevant trials.

SELECTION CRITERIA

Randomized controlled trials (RCTs) that compared the effects of PRP and other treatments on plantar fasciitis were included.

DATA COLLECTION AND ANALYSIS

The main outcomes included changes from baseline in visual analog scale (VAS) score, American Orthopaedic Foot and Ankle Society Score (AOFAS), and Roles-Maudsley score (RMS). Results were expressed as weight mean difference (WMD) with 95% confidence interval (95% CI). The meta-analysis was performed using a fixed-effects or random-effects model according to heterogeneity.

MAIN RESULTS

Ten RCTs involving a total of 445 patients with plantar fasciitis were included. Among these studies, 9 compared PRP with steroid, and 1 compared PRP with whole blood.Four studies were categorized as being at low risk of bias, and the remaining 6 as being at unclear risk of bias.Pooled estimates suggested that PRP had greater changes in VAS and AOFAS scores than other treatments. However, it had no benefit effect in the RMS.Subgroup analysis for VAS and AOFAS showed that PRP had superior effect than other treatments at 12 months, but not at the 1, 3, 6 months.Subgroup analysis based on treatment regimens demonstrated that PRP was more effective than steroid in the change from baseline in AOFAS, but not in VAS and RMS scores.

AUTHORS' CONCLUSION

PRP was as effective as other treatments in reducing pain and improving function in patients with plantar fasciitis. Subgroup analysis indicated that PRP had better effect than steroid in AOFAS Score and its effect was durable in a long term. However, considering the potential limitations in this study, more large-scale RCTs are needed to confirm the current findings.

Custom foot orthoses improve first-step pain in individuals with unilateral plantar fasciopathy: a pragmatic randomised controlled trial

BACKGROUND

Foot orthoses are routinely used to treat plantar fasciopathy in clinical practice. However, minimal evidence exists as to the effect of both truly custom designed foot orthoses, as well as that of the shoe the foot orthoses are placed into. This study investigated the effect of wearing custom foot orthoses and new athletic footwear on first-step pain, average 24-h pain and plantar fascia thickness in people with unilateral plantar fasciopathy over 12 weeks.

METHODS

A parallel, three-arm randomised controlled trial with blinding of participants and assessors. 60 participants diagnosed with unilateral plantar fasciopathy were randomised to either custom foot orthoses and new shoes (orthoses group), a sham insole with a new shoes (shoe group) or a sham insole placed in the participant's regular shoes (control group). Primary outcome was first-step pain. Secondary outcomes were average 24-h pain and plantar fascia thickness measured on ultrasound. Outcomes were assessed at baseline, 4 week and 12 week trial time-points.

RESULTS

At 4 weeks, the orthoses group reported less first-step pain (p = 0.002) compared to the control group. At 12 weeks, the orthoses group reported less first-step pain compared to both the shoe (p = < 0.001) and sham (p = 0.01) groups. Both the orthoses (p = < 0.001) and shoe (p = 0.006) groups reported less average 24-h pain compared to the control group at 4 and 12 weeks. The orthoses group demonstrated reduced plantar fascia thickness on ultrasound compared to both the shoe (p = 0.032) and control groups (p = 0.011).

CONCLUSIONS

Custom foot orthoses in new shoes improve first-step pain and reduce plantar fascia thickness over a period of 12 weeks compared to new shoes alone or a sham intervention.

Application of High Energy Extracorporeal Shockwave Therapy on Musculoskeletal Conditions in US Military Medical Facilities

Outcomes of extracorporeal shockwave therapy (ESWT) vary due to the heterogeneity of application protocols and patient characteristics. United States military medical facilities offer a unique environment to study the effects of ESWT due to the large use, consistent protocol, and ability to care for young active individuals. A retrospective review was conducted from November 2008 to March 2015 to assess types of musculoskeletal conditions treated by ESWT in US military medical treatment facilities, the demographics of patients treated with ESWT (age and gender), the trend throughout the time in question, and the protocols implemented. A literature review was performed to compare the use in US military facilities to reported data. In this study we report how US military medical facilities are using ESWT to treat musculoskeletal conditions and outcomes reported in literature. The purpose of our research is to raise awareness of this treatment modality and areas for further research within the US military medical facilities.

Comparison of Plantar Fasciitis Injected With Platelet-Rich Plasma vs Corticosteroids

BACKGROUND

Plantar fasciitis is one of the most common causes of heel pain. This prospective study compared the efficacy of local injection of corticosteroids vs platelet-rich plasma (PRP) in the treatment of plantar fasciitis.

METHODS

Patients were randomly allocated into 2 groups of 40 each (group A and group B). Patients were treated with local corticosteroid injection in group A and autologous PRP injection in group B. Clinical assessment was done prior to the injection and at 1 month, 3 months, and 6 months following the injection, which included visual analog pain scale, subjective rating using the modified Roles and Maudsley score, functional outcome score by the Foot and Ankle Outcome Instrument (FAI) core scale, and the American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot scale. Radiological assessment was done by measuring the thickness of the plantar fascia using ultrasonography. The mean age, sex, and body mass index of both groups were comparable.

RESULTS

Postinjection, there was significant improvement of visual analog score, modified Roles and Maudsley score, FAI core scale, AOFAS ankle-hindfoot score, and plantar fascia thickness in both the groups. However, with the numbers available, no significant difference in improvement could be detected between the above-mentioned variables in the 2 groups.

CONCLUSION

We found that the treatment of plantar fasciitis with steroid or PRP injection was equally effective.

Minimally invasive non-surgical management of plantar fasciitis: A systematic review

BACKGROUND

Minimally invasive non-surgical techniques have been widely used worldwide to treat musculoskeletal injuries. Of these techniques, injectable pharmaceutical agents are the most commonly employed treatments, with corticosteroids being the most widely used drugs. The aim of this article is to review current scientific evidence as well as the effectiveness of minimally invasive non-surgical techniques, either alone or combined, for the treatment of plantar fasciitis.

METHODS

This systematic review was conducted from April 2016 until March 2017, in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement and was registered with PROSPERO. Randomized controlled trials (RCTs) of adult patients diagnosed with plantar fasciitis were included as well as intervention studies, with a minimal sample size of 20 subjects per study (10 per group). Assessment of study eligibility was developed by three reviewers independently in an unblinded standardized manner. The physiotherapy evidence database (PEDro) scale was used to analyse the methodological quality of studies.

RESULTS

Twenty-nine full-text articles on minimally invasive techniques were reviewed. These articles focused on corticosteroid injections, platelet-rich plasma, Botox, dextrose injections, as well as comparative studies with dry needling vs sham needling.

CONCLUSION

The treatment of plantar fasciitis has dramatically improved in the past decade with minimally invasive techniques becoming increasingly available. Research findings have shown that the long term effects of minimally invasive (non-surgical) treatments such as shock wave therapy, botulinum toxin type-A injections, platelet-rich plasma injections and intratissue percutaneous electrolysis dry needling show similar and sometimes better results when compared to only corticosteroid injections. The latter have been the mainstay of treatment for many years despite their associated side effects both locally and systemically. To date, there is no definitive treatment guideline for plantar fasciitis, however the findings of this literature review may help inform practitioners and clinicians who use invasive methods for the treatment of plantar fasciitis regarding the levels of evidence for the different treatment modalities available.

Ultrasonography and clinical outcome comparison of extracorporeal shock wave therapy and corticosteroid injections for chronic plantar fasciitis: A randomized controlled trial

OBJECTIVES

Extracorporeal shockwave therapy (ESWT) and corticosteroid injection (CSI) are treatment options for plantar fasciitis. Their clinical outcome comparison remains a debate. Also, the thickness changes of the plantar fascia on objective evaluation under the medium energy ESWT and CSI therapy are elusive.

METHODS

A total of 97 patients with chronic plantar fasciitis were enrolled in the randomized prospective trial. Forty-seven patients received extracorporeal shock wave therapy (ESWT), and fifty patients received corticosteroid injection (CSI). The thickness of the plantar fascia was evaluated respectively before ESWT and CSI, and at the 4th and 12th week after ESWT and CSI by ultrasonography. Pain level and clinical outcomes were recorded using visual analogue scale (VAS) and 100-points scoring systems. Correlation analysis was performed between the thickness change and clinical outcome.

RESULTS

Under ultrasonography, we observed more increase of plantar fascia thickness of ESWT group than CSI group at 4th week (p=0.048). VAS of plantar fasciitis patients receiving ESWT was lower than those who received corticosteroid injection (0.001 and p⟨0.001, at 4th and 12th week). On the assessment of 100-points scoring systems, the pain level of patients with ESWT was lower than those with CSI at the 12th week (p⟨0.001). On the other hand, the increase of plantar fascia thickness at 4th week was positively correlated with the decrease of VAS score at 12th week follow-up (R=0.302, P=0.039).

CONCLUSIONS

At 4th week after treatment, the thickness of plantar fascia increased. Then it decreased gradually, but not to the baseline at 12th week. On the pain level outcome at 12th week, extracorporeal shockwave therapy (ESWT) was more efficient than corticosteroid injection (CSI) on chronic plantar fasciitis. The more change of plantar fascia after ESWT, the more efficient on clinical outcome.

[Prognostic analysis of plantar fasciitis treated by pneumatic ballistic extracorporeal shock wave versus ultrasound guided intervention]

OBJECTIVE

To compare the medium- and long-term effect of pneumatic ballistic extracorporeal shock wave versus ultrasound-guided hormone injection in the treatment of plantar fasciitis.

METHODS

The clinical data were collected from patients with plantar fasciitis admitted to PLA General Hospital pain department from September, 2015 to February, 2017. The patients were randomly divided into ultrasound-guided drug injection group and shock wave group. The therapeutic parameters including the numerical rating scale (NRS) scores in the first step pain in the morning, American Orthopedic Foot and Ankle Society (AOFAS) Ankle Hindfoot Scale, and thickness of the plantar fascia were monitored before and at 1 week, 1 month, 3 months, and 6 months after the treatment. The recurrence rate, effectiveness, and patient satisfaction were compared between the two groups at 6 months after the treatment.

RESULTS

Thirty-nine patients were enrolled in shock wave group and 38 patients in ultrasound group. The NRS scores in the first step pain in the morning were lowered after treatment in both groups (P<0.05), and the scores were significantly lower in ultrasound group than in shock wave group at 1 week and 1 month (P<0.01), but significantly higher in ultrasound group than in shock wave group at 3 and 6 months after treatment (P<0.05). The AOFAS functional scores were increased in both groups (P<0.05) at 6 months after treatment, was significantly lower in ultrasound group than in shock wave group than group B (90.44∓13.27 vs 75.76∓21.40; P<0.05). The effective rates in shock wave group and ultrasound group were 92.31% and 76.32%, respectively (P<0.05). Recurrence was found in 1 patient (2.56%) in shock wave group and in 8 (21.05%) in ultrasound group (P<0.05). The patient satisfaction scores were significantly higher in shock wave group than in ultrasound group (8.13∓2.67 vs 6.63∓3.75, P=0.048).

CONCLUSION

Pneumatic ballistic extracorporeal shock achieves better medium- and long-term outcomes than ultrasound-guided hormone injection in the treatment of plantar fasciitis.

Foot and Ankle Conditions: Plantar Fasciitis

Plantar fasciitis is the most common cause of heel pain in adults. It involves painful symptoms occurring along the plantar fascia with or without the presence of a bony heel spur. Heel pain that occurs on standing after a prolonged non-weight-bearing period is a prominent symptom of plantar fasciitis. On physical examination, palpation along the medial plantar calcaneal region reproduces the painful symptoms. Routine imaging studies usually are not necessary but can be used to rule out pathologies or confirm chronic or recalcitrant plantar fasciitis. The presence of a heel spur on x-ray is not thought to be an underlying cause of symptoms and indicates the condition has been present for at least 6 to 12 months. Conservative therapies such as rest, ice massage, nonsteroidal anti-inflammatory drugs, specific plantar fascia stretching exercises, and orthoses are the preferred initial treatments. Injection therapies using a corticosteroid or platelet-rich plasma typically provide short-term relief. If conservative treatment is ineffective, extracorporeal shock wave therapy and surgery may be considered.

The influence of dosing on effect size of exercise therapy for musculoskeletal foot and ankle disorders: a systematic review

OBJECTIVE

The purpose of this review was to identify doses of exercise therapy associated with greater treatment effect sizes in individuals with common musculoskeletal disorders of the foot and ankle, namely, achilles tendinopathy, ankle sprains and plantar heel pain.

METHODS

AMED, EMBASE and MEDLINE were searched from 2005 to August 2017 for randomized controlled trials related to exercise for these three diagnoses. The Physiotherapy Evidence Database scale was used for methodological quality assessment. Exercise dosing variables and outcome measures related to pain and function were extracted from the studies, and standardized mean differences were calculated for the exercise groups.

RESULTS

Fourteen studies met the final inclusion. A majority of the studies showed large effects and two small trends were identified. Patients with plantar heel pain may benefit more from a daily home exercise program than two supervised visits per week (SMD=3.82), but this recommendation is based on weak evidence. In achilles tendinopathy, a relationship was also seen when sets and repetitions of eccentric exercise were performed as tolerated (SMD=1.08 for function, -1.29 for pain).

CONCLUSIONS

Session duration, frequency, total number of visits, and overall length of care may all be dosing variables with limited value for determining effective exercise prescription. However, the limited number of studies prevents any definitive conclusions. Further investigation is warranted to improve our understanding of the influence exercise dosing has on treatment effect sizes. Future randomized controlled trials comparing specific exercise dose variables should be conducted to clarify the impact of these variables.

Multidimensional impact of low-Dye taping on low-load hopping in individuals with and without plantar fasciitis

OBJECTIVES

Evaluate the acute effect of low-Dye, placebo and no tape on motor behaviour in individuals with plantar fasciitis (PF).

DESIGN

Prospective, experimental.

SETTING

Motion analysis laboratory.

PARTICIPANTS

Ten participants with PF and ten matched controls.

MAIN OUTCOME MEASURES

Hopping behaviour (lower-limb stiffness and ankle angle at peak loading) were evaluated during low-load sleigh hopping, during three taping conditions. Stiffness and ankle angle were determined using three-dimensional motion analysis. Pain during submaximal loading was assessed with a numeric pain rating scale.

RESULTS

The lower-limb stiffness response to therapeutic taping was modulated by the presence of PF (interaction, F = 4.48, p = 0.018). Matched controls demonstrated a significant increase in stiffness post application of low-Dye taping (p = 0.001), stiffness was unchanged in the PF group. In the PF group, low-Dye taping decreased hopping pain in comparison to placebo (p = 0.037) and no-tape (p = 0.024). There was no difference in ankle angle at peak loading between the groups or across taping conditions.

CONCLUSIONS

Low-Dye taping reduces nociceptive inputs more than placebo in the presence of PF pain. Low-Dye tape alters stiffness in the control group but not the PF group. The motor behavioural outputs such as stiffness, during low-load hopping is modulated by both pathology and therapeutic taping.
