Extracorporeal shockwave therapy in the management of plantar fasciitis: A randomized controlled trial

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

OBJECTIVES

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

METHODS

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

RESULTS

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

CONCLUSION

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

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

Background

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

Method

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

Results

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

Conclusion

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

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.

Similar Benefits Seen After Radial Extracorporeal Shockwave Therapy or Autologous Blood Injection in Patients With Chronic Plantar Fasciitis-A Retrospective Cohort Study

OBJECTIVE

To compare the outcomes for patients with chronic plantar fasciitis after extracorporeal shockwave therapy (ESWT) or autologous blood injection (ABI).

DESIGN

Cohort study-retrospective analysis of prospectively collected data.

SETTING

Hospital-based Sports Medicine Outpatient Clinic.

PATIENTS

One hundred two consecutive patients with chronic plantar fasciitis, treated with either radial-ESWT (rESWT) (n = 54) or ABI (n = 48), with minimum 3-month follow-up and 96% (98/102) having 6-month follow-up. Mean age 49.5 years and mean duration of symptoms 37.5 months before treatment.

INTERVENTIONS

Patients received either 3 sessions of radial ESWT (one session per week for 3 weeks), or a single ultrasound-guided dry needling and ABI (3 mL whole autologous blood). All patients received standardized after-care, including progressive structured home exercise program of flexibility, strengthening, and proprioception exercises.

MAIN OUTCOME MEASURES

0 to 10 numerical rating scale (NRS) for self-reported "average pain" and "average stiffness" values. Secondary outcome measures included assessments of local foot function [including Manchester-Oxford Foot Questionnaire (MOXFQ), revised-Foot Function Index] as well as markers of mental health functioning (HAD), global health (EQ-5D-5L), and physical activity (International Physical Activity Questionnaire).

RESULTS

This study demonstrated statistically significant improvements in self-reported measures of pain and local foot function after either procedure at 6 weeks, 3 months, and 6 months, but no statistically significant differences were seen between groups at any time-period studied. At 6 months, the average pain using a 0 to 10 NRS was improved from 6.8 ± 1.8 to 4.0 ± 2.7 (P < 0.001) after ESWT and from 7.1 ± 1.6 to 3.8 ± 2.7 (P < 0.001) after ABI. At 6 months, significant improvements were seen following either group using a number of different validated patient-rated outcome measures assessing local foot pain and function, eg, the total score for MOXFQ improved from 56.1 ± 12.8 to 42.5 ± 16.6 (P < 0.001) after ESWT and from 58.8 ± 13.2 to 44.2 ± 19.2 (P < 0.001) after ABI. However, measures of physical activity or wider aspects of patient functioning did not consistently improve from baseline values to follow-up periods.

CONCLUSIONS

Patients with chronic plantar fasciitis improved to statistically significant extent after either rESWT or ABI procedures, with no significant differences seen between groups. The lack of randomization in this pragmatic study is noted, which may have influenced the outcome seen. Potentially larger and more robust studies are required to investigate this treatment comparison further.

Effectiveness of Gastrocnemius-Soleus Stretching Program as a Therapeutic Treatment of Plantar Fasciitis

Introduction: Plantar fasciitis is a painful ailment that causes frustration to both the patient and physician. Stretching exercises targeting the plantar fascia are an excellent therapy option for plantar fasciitis.

Objective: To compare the outcome of a gastrocnemius-soleus stretching program versus tendo Achilles stretching exercises for the management of chronic plantar fasciitis.

Methods: Patients aged 30-70 years of either gender with chronic plantar fasciitis were included and randomly divided into two groups. In group A, the gastrocnemius-soleus stretching program was applied, whereas in group B, the tendo Achilles stretching exercises were adopted. The pain score was determined at baseline and after eight weeks, and the change in pain score was calculated. All information was noted in the proforma and then entered and analyzed in the Statistical Package for the Social Sciences (SPSS) software version 21 (International Business Machines (IBM), New York, United States). An independent-samples t-test was conducted to compare the mean change in pain score in both groups. A P value of <0.05 was considered significant.

Results: The mean age of the patients in the gastrocnemius-soleus stretching group was 48.70 ± 9.80 years, whereas that in the tendo Achilles stretching exercises group was 48.63 ± 8.43 years. Group A included 16 (53.3%) men and 14 (46.7%) women, whereas in group B, there were 15 (50%) men and 15 (50%) women. The mean change in pain score in group A was 2.57 ± 1.01, whereas that in group B was 1.77 ± 0.57. The difference in both groups was significant (P < 0.05).

Conclusion: Gastrocnemius-soleus stretching exercises are more effective for reducing the symptoms of plantar fasciitis in the adult population.

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
