Clinical Outcomes After Extracorporeal Shock Wave Therapy for Chronic Plantar Fasciitis in a Predominantly Active Duty Population

Comparative retrospective analysis of magnetic field therapy and extracorporeal shock wave therapy in pain management for heel spur

BACKGROUND

Heel spurs, caused by inflammation and overstretching of the plantar fascia, are a common source of heel pain. Although various conservative and invasive treatments are used, evidence on their effectiveness remains limited.

OBJECTIVE

This study aims to evaluate the effect of extracorporeal shock wave therapy (ESWT) and magnetic field application on pain levels in heel spur patients.

METHODS

The files of 80 patients diagnosed with heel spurs were accessed. Patients with missing demographic information in the files, incomplete Visual Analogue Scale (VAS) values, and patients with heel pain complaints for less than 5 months were excluded from the study. A total of 39 patients who met the study criteria were included in the study. While ESWT was applied to 21 of these patients (ESWT group), magnetic field was applied to 18 patients (MA group). All patients were given plantar fascia stretching exercises as a home program. Pain scores before and after treatment were evaluated with VAS.

RESULTS

A significant decrease was found in VAS values after the 5th session and 2 months later in both the ESWT group and the magnetic field group (p < 0.001). On the other hand, neither treatment method was found to be superior to each other (p > 0.05).

CONCLUSION

It was observed that the pain of the patients decreased in both the early and late periods in both applications.

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

Background

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

Objective

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

Methods

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

Results

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

The role of corticosteroid injections in treating plantar fasciitis: A systematic review and meta-analysis

BACKGROUND

Plantar fasciitis is a recurrent cause of heel pain and is often treated by corticosteroid infections (CSI). The current study reviewed and analysed the role of CSI with platelet rich plasma (PRP), and CSI with extracorporeal shock wave therapy (EWST) for plantar fasciitis treatment.

METHODS

PubMed, Medline, Web of Science, Embase, Cochrane, and Google Scholar databases were searched for relevant studies. Preferred Reporting in Systematic Review & Meta-Analysis (PRISMA) guidelines were used to search relevant studies published from infinity to April 2021. The risk of bias was performed using Cochrane Collaboration's tool. GRADE assessment was used for quality of evidence. Data analysis was performed with the use of R software and P < 0.05 was considered statistically significant. CSI was compared with PRP and EWST.

RESULTS

Eighteen studies comprising 1180 patients were included in this meta-analysis. When compared to PRP, CSI with lignocaine/lidocaine had significantly higher mean difference on visual analogue scale (VAS) pain scores at 3 months (0.62 [0.13; 1.12], P = 0.01) and 6 months (MD = 1.49 [0.22; 2.76], P = 0.02). At 6 months, VAS scores were higher in the CSI group than the ESWT group (MD = 0.8 [0.38; 1.22], P = 0.1). At 6 months, a significant reduction in the American Orthopaedic Foot and Ankle Score (AOFAS) was observed in the CSI group compared to PRP (MD = - 11.53 [- 16.62; - 6.43], P < 0.0001).

CONCLUSION

Patients suffering from plantar fasciitis, PRP achieved better VAS scores compared to CSI at 3 and 6-month follow-up. In addition, ESWT had better VAS score outcomes at 6 months compared to CSI. Regarding AOFAS score, PRP was more efficacious than CSI at 6 months of follow-up. Only through the development of high-quality, large-scale longitudinal studies, will the findings and conclusions of this meta-analysis be strengthened and influence our clinical practice in the treatment of plantar fasciitis.

The therapeutic effect of extracorporeal shock wave therapy combined with Kinesio Tape on plantar fasciitis

BACKGROUND

Extracorporeal shock wave therapy (ESWT) combined with Kinesio Tape (KT) for plantar fasciitis (PF) is lacking in the literature.

OBJECTIVE

This study aimed to investigate the effect of ESWT combined with KT on foot pain and function in patients with PF based on ultrashort wave therapy and stretching.

METHODS

A total of 91 patients with PF were randomly divided into the ESWT group (ETG, n= 23), KT group (KTG, n= 23), combined treatment group (CTG, n= 22) and control group (CG, n= 23). Herein, changes in visual analysis scale (VAS) score, plantar fascia thickness (PFT) and American Orthopaedic Foot and Ankle Society (AOFAS) score were examined.

RESULTS

The groups were compared after 4 weeks and the results showed that the VAS scores of ETG, KTG and CTG were significantly smaller than that of CG (P< 0.05). In addition, the VAS score of CTG was significantly smaller than that of KTG (P< 0.001). Meanwhile, the AOFAS scores of ETG and CTG were significantly greater than that of CG (P< 0.001). Moreover, the AOFAS score of CTG was significantly greater than those of ETG and KTG (P< 0.01). Comparisons within groups were also conducted at weeks 0 and 4 and the results showed that the VAS scores of ETG, KTG and CTG significantly decreased (P< 0.001); the PFT of ETG and CTG significantly decreased (P< 0.05); and the AOFAS score of ETG, KTG and CTG significantly increased (P< 0.001).

CONCLUSION

Based on ultrashort wave therapy and stretching, ESWT and KT therapy could improve the foot pain and function of patients with PF, and the combined modality therapy is more effective. ESWT and combined treatment has a positive effect on patients' PFT. However, single KT treatment has a limited effect on PFT.

Radial Extracorporeal Shockwave Therapy (rESWT) is not superior to "minimal-dose" rESWT for patients with chronic plantar fasciopathy; a double-blinded randomised controlled trial

BACKGROUND

Investigating outcomes following radial-extra-corporeal-shockwave-therapy (rESWT) in patients with chronic plantar fasciopathy METHODS: This double-blinded RCT in a single NHS Sports medicine clinic recruited 117 patients with chronic plantar fasciopathy randomised equally to either 3 sessions of rESWT or "minimal-dose" respectively. Mean age 51.7 ± 9.6 years, 66 % female, symptom duration: 32.6 ± 30.8 months.

RESULTS

"Average pain" improved by 50 % at 6-months, (>1/3 at interim time-points). Statistically significant within-group improvements were identified in pain, local function, and "ability" PROMs in both groups. Fewer benefits in activity levels or mood. No between-group differences were seen at the interim or final time-points.

CONCLUSION

3 sessions of "recommended-dose" rESWT is non-superior to "minimal-dose" rESWT in patients with chronic plantar fasciopathy. rESWT may be ineffective in the treatment of patients with chronic plantar fasciopathy, "minimal-dose" rESWT may be sufficient for a therapeutic effect, or a greater number of treatment sessions may be required for benefit.

Myofascial points treatment with focused extracorporeal shock wave therapy (f-ESWT) for plantar fasciitis: an open label randomized clinical trial

BACKGROUND

Plantar fasciitis (PF) is a common cause of heel pain. Among the several conservative treatment options, extracorporeal shock wave therapy (ESWT) is considered the standard treatment. However, recent studies suggest that PF may be sustained by a myofascial impairment proximal to the pain area with a biomechanical disequilibrium of the entire limb and pelvis.

AIM

By combining the concepts of fascial manipulation and ESWT, the purpose of this study was to evaluate the effectiveness of the ESWT on myofascial points in a sample of subjects with PF.

DESIGN

Open label randomized controlled clinical trial.

SETTING

Outpatient clinic.

POPULATION

Patients with PF were randomly assigned to an experimental treatment group (EG), treated with focused ESWT on myofascial points, and a control group (CG), treated with the focused ESWT traditional approach on the medial calcaneal tubercle.

METHODS

Every patient underwent a 3-session program and follow-up after 1 and 4 months. Outcome measures included the Foot and Ankle Outcome Score (FAOS) and the Italian Foot Functional Index (17-iFFI).

RESULTS

Thirty patients were enrolled in the study. Four patients of the CG dropped out the study, therefore twenty-six patients were included in the final analysis. Improvement in 17-iFFI and FAOS scores was observed in both groups starting from the third treatment and confirmed at the 1-month and 4-month follow-ups, with earlier improvement in the score values observed in the EG.

CONCLUSIONS

Treatment of the myofascial points with ESWT in subjects suffering from plantar fasciitis could be an effective treatment option. It fosters the hypothesis that a global biomechanical re-equilibrium of the body would be necessary to completely solve the pathology.

CLINICAL REHABILITATION IMPACT

ESWT on myofascial points could provide an interesting alternative with better outcomes in terms of time needed for recovery compared to traditional ESWT for the conservative management of PF.

Effects of shock wave therapy in patients with carpal tunnel syndrome: a systematic review and meta-analysis

PURPOSE

To determine whether shock wave therapy could improve symptoms and hand function in patients with carpal tunnel syndrome.

MATERIALS AND METHODS

Medline, Embase, Physiotherapy Evidence Database, the Cochrane Central Register of Controlled Trials, OpenGrey, CNKI, VIP, Wang Fang databases, and China Biological Medicine were searched, from inception to December 2019.

RESULTS

Ten trials involving 433 patients (501 wrists) were included in this systematic review. The shock wave therapy was observed to have a significant effect on pain relief (MD: -0.60, 95% CI: -1.16 to -0.05, p = 0.03), syndrome alleviation (MD: -2.26, 95% CI: -3.24 to -1.27, p < 0.00001) and functional recovery (MD: -1.25 95% CI: -2.08 to -0.43, p = 0.003) among the carpal tunnel syndrome patients. As revealed by the subgroup analysis, radial shock wave therapy made a significant difference in pain relief, syndrome alleviation, and functional recovery (p < 0.05). Focused shock wave had no significant effect on pain relief, syndrome alleviation, and functional recovery (p > 0.05).

CONCLUSION

Shock wave therapy could be conductive to improve syndrome and hand function for carpal tunnel syndrome patients.Implications for rehabilitationShock wave therapy is beneficial for alleviating syndrome and improving hand function of carpal tunnel syndrome patients.Radial shock wave therapy seems superior to focused shock wave therapy on syndrome alleviation and functional recovery of hand in carpal tunnel syndrome patients.

Efficacy of Unfocused Medium-Intensity Extracorporeal Shock Wave Therapy (MI-ESWT) for Plantar Fasciitis

Extracorporeal shock wave therapy (ESWT) is a promising treatment for plantar fasciitis (PF), however, treatment results have varied due to inconsistencies among types of shock wave treatment and devices used. This retrospective chart review includes patients who underwent ESWT using the OrthoGold 100™ shock wave device (MTS, Konstanz, Germany) for PF between January, 2013 and September, 2018. There were 108 patients (119 heels) identified, with a mean age of 51.7 ± 16.5 (Range 21-83) years. Patients were treated weekly for 3 weeks, with 2000 impulses per session at an energy flux density between 0.10 and 0.17 mJ/mm². Mean follow-up duration was 11.5 ± 9.7 (Range 3-51) months. Mean pre-ESWT pain visual assessment scale improved from 6.7 ± 1.7 to 2.6 ± 2.7 (p < .001). The Foot and Ankle Outcome Score subscales: pain, function of daily living, function of sports and recreational activities and quality of life domains improved from 53.7 ± 14.9 to 75.7 ± 16.7 (p < .001), from 38 ± 15.2 to 71.8 ± 23 (p < .001), from 55.8 ± 16.4 to 71.4 ± 18 (p < .001), from 42.4 ± 21.5 to 59.4 ± 20.3 (p < .001) and from 44.9 ± 16.4 to 69 ± 23.9 (p < .001), respectively. Eighty-eight (81.5%) patients were satisfied with the procedure at final follow-up. Treatment of PF with unfocused shock waves was well tolerated and led to significant pain reduction, functional improvement, and patient satisfaction.

Comparison of Effectiveness of Density and Number of Sessions of Extracorporeal Shock Wave Therapy in Plantar Fasciitis Patients: A Double-Blind, Randomized-Controlled Study

This study aimed to investigate the effect of density and number of sessions extracorporeal shock wave therapy (ESWT) on pain, fatigue, disability, physical function, and quality of life in patients with plantar fasciitis (PF). Between September 2019 and December 2019, a total of 94 patients with the diagnosis of PF were included in the study. All patients were randomly divided into 3 groups. Group 1 (n = 33) received a total of 7 sessions of high-energy flux density (H-ESWT) (0.26 mJ/mm² ) , group 2 (n = 31) received a total of 3 sessions of H-ESWT (0.26 mJ/mm²), group 3 (n = 30) received total of 7 sessions of low-energy flux density (<0.08 mJ/mm²) with 3 days interval. At baseline and 1 month after the treatment, the Visual Analog Scale (VAS), Short Form-36, Foot Function Index (FFI), Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue Scale, and Six-Minute Walking Test (6MWT) scores were compared among the groups. Of the patients, 69 were females and 25 were males with a mean age of 45.0 ± 8.43 (range, 25-67) years. There were no statistically significant differences in the age, sex, demographic characteristics, and baseline VAS, FFI, 6MWT, and FACIT scores between the groups (p > .05). However, there was a statistically significant decrease in the VAS, FACIT, and FFI scores in all groups after treatment compared to baseline, although only the 6MWT, and Short Form-36 subscale scores were statistically significantly higher (p < .05). There was also a statistically significant difference in the scale scores in Group 1 versus Group 2 and in Group 2 versus Group 3. Our study results suggest that H-ESWT for high number of sessions is more effective than LESWT for low number of sessions on pain, quality of life, physical function, fatigue, and disability in patients with PF.

Platelet-Rich Plasma Versus Corticosteroids in the Treatment of Chronic Plantar Fasciitis: A Systematic Review and Meta-analysis of Prospective Comparative Studies

Plantar fasciitis is a common cause of heel pain, which often results in a significant limitation of daily activity. The objective of this review was to compare platelet-rich plasma injection (PRP) and corticosteroids injection in the treatment of chronic plantar fasciitis. MEDLINE, PubMed, Web of Science, EMBASE, and the Cochrane library of clinical trials were searched in March 2019. Inclusion criteria were prospective comparative studies reporting functional scores or pain score with a minimum follow-up of 1 month. We excluded studies with patients younger than 18 years and patients with a history of surgical intervention, infection, or rheumatological disease. First author, publication year, sample size, type of intervention, outcome measures, and follow-up period were recorded. The American Orthopaedic Foot & Ankle Society score was significantly better in the PRP group at 6 months' follow-up, with a lower visual analogue scale at 6- and 12-month intervals. The Foot and Ankle Disability Index and Roles-Maudsley score were similar in the 2 treatments at 3 and 6 months. PRP injection in the treatment of chronic plantar fasciitis is considered safe, with a favorable functional outcome and pain control at intermediate and long-term follow-up in comparison to corticosteroid injection.

Comparison Between Extracorporeal Shock Wave Therapy and Local Corticosteroid Injection for Plantar Fasciitis

BACKGROUND

Extracorporeal shock wave therapy (ESWT) is a nonsurgical treatment for plantar fasciitis (PF) that has had satisfactory clinical outcomes. However, local corticosteroid injection (LCI) is often regarded as first-line treatment of PF, but there have been few studies comparing the 2 methods. Therefore, we compared the effect of ESWT and LCI on patients with PF.

METHODS

This was a block randomized controlled study comparing 49 patients treated with ESWT and 47 patients treated with LCI from January 2017 to December 2018 who were followed for 6 months. We evaluated the clinical outcomes in the 2 groups, including average pain, first-step pain, plantar fascia thickness, and Foot Function Index, Chinese version of the PF patients.

RESULTS

All patients had pain relief and function improvement after treatment, whereas the LCI group did not maintain significant clinical improvement at the 3-month follow-up. The patients in the ESWT group had a significantly better clinical outcome with better duration of improvement than the LCI group.

CONCLUSION

For PF patients, both ESWT and LCI resulted in clinical improvement but EWST provided longer relief than LCI.

A global approach for plantar fasciitis with extracorporeal shockwaves treatment

Extracorporeal Shockwaves Treatment is considered an effective therapeutic option for plantar fasciitis, but the standard application in the medial insertion of the plantar fascia on the calcaneus has provided ambiguous evidences. In this case, a 63-year man with plantar fasciitis was treated in a 3-session program and Foot and Ankle Outcome Scale and Foot Functional Index questionnaires were chosen for the clinical outcome evaluation. The therapy was focused on the active trigger or myofascial points of the leg, thigh and pelvis in order to return the correct equilibrium of the myofascial system of the whole limb. The patient has already reported an improvement after the second session (FAOS: 76 vs 33, FFI: 85%) which was confirmed in the third one and in the 1-month follow up (FAOS: 79, FFI: 6%) Results suggest that plantar fasciitis may be due to proximal rigidity or tension of the fascia and a global approach using ESWT may have a similar or better outcome respect to the standard application.

Does radial extracorporeal shockwave therapy impair hearing function in patients with plantar fasciitis?

Background:

Radial extracorporeal shock wave therapy (r-ESWT) is commonly used for the treatment of chronic plantar fasciitis. Previously in the urology literature, some studies reported hearing impairment after extracorporeal shock wave lithotripsy. However, there is no study that evaluates the possible side effects of r-ESWT on the hearing function of patients. The aim of this study was to investigate the effects of r-ESWT on the pure tone audiometry of the patients on whom r-ESWT was applied for chronic plantar fasciitis.

Material and Methods:

Patients with the diagnosis of plantar fasciitis who were treated with r-ESWT were included in this prospective case-control study. Before and after the r-ESWT application, all patients were consulted to our otolaryngology department for pure tone audiometric examination to detect any hearing impairment before and after the treatment. A control group was also constructed that consisted of patients who were admitted to our department for any complaint.

Results:

A total of 67 patients participated in the study. Radial ESWT group consisted of 47 patients (39 female, 8 male) with the mean age of 44.1 years. The control group consisted of 20 patients (12 female, 8 male) with the mean age of 36.9 years. We observed a 20-dB threshold shift at 8000Hz in 1 patient who had no clinical symptom. This patient had no threshold shift at the 1-month control audiometric measurement.

Conclusion:

According to the results acquired from this study, we can consider that r-ESWT treatment in patients with chronic plantar fasciitis has no markedly detrimental effect on the hearing function.

Use of artificial neural networks to identify the predictive factors of extracorporeal shock wave therapy treating patients with chronic plantar fasciitis

The purpose of our study is to identify the predictive factors for a minimum clinically successful therapy after extracorporeal shock wave therapy for chronic plantar fasciitis. The demographic and clinical characteristics were evaluated. The artificial neural networks model was used to choose the significant variables and model the effect of achieving the minimum clinically successful therapy at 6-months’ follow-up. The multilayer perceptron model was selected. Higher VAS (Visual Analogue Score) when taking first steps in the morning, presence of plantar fascia spur, shorter duration of symptom had statistical significance in increasing the odd. The artificial neural networks model shows that the sensitivity of predictive factors was 84.3%, 87.9% and 61.4% for VAS, spurs and duration of symptom, respectively. The specificity 35.7%, 37.4% and 22.3% for VAS, spurs and duration of symptom, respectively. The positive predictive value was 69%, 72% and 57% for VAS, spurs and duration of symptom, respectively. The negative predictive value was 82%, 84% and 59%, for VAS, spurs and duration of symptom respectively. The area under the curve was 0.738, 0.882 and 0.520 for VAS, spurs and duration of symptom, respectively. The predictive model showed a good fitting of with an overall accuracy of 92.5%. Higher VAS symptomatized by short-duration, severer pain or plantar fascia spur are important prognostic factors for the efficacy of extracorporeal shock wave therapy. The artificial neural networks predictive model is reasonable and accurate model can help the decision-making for the application of extracorporeal shock wave therapy.
