Extracorporeal shock wave therapy on pain and foot functions in subjects with chronic plantar fasciitis: systematic review of randomized controlled trials

Comparison of the Short-Term Effect between Iontophoresis and Radial Extracorporeal Shockwave Therapy in the Treatment of Plantar Fasciitis: A Randomized Controlled Trial

Conservative treatments for plantar fasciitis have different levels of effectiveness, so it is necessary to personalize the therapeutic modality that improves the patients' symptoms.

METHODS

A double-blinded randomized clinical trial was designed to evaluate the short-term efficacy of a physical treatment in chronic plantar fasciitis, namely iontophoresis, compared with radial shockwave therapy. Heel pain, health status using the EuroQol-5D questionnaire, and fascia thickness measured with ultrasound were evaluated. In total, 127 patients were randomly selected for group A and treated with iontophoresis therapy (lidocaine 0.4% and dexamethasone 0.5%), or for group B, in which they were treated with radial shockwave therapy (EWST). Measurements were taken at baseline and at follow-up during the 5 weeks of the study.

RESULTS

Statistically significant differences were observed to the shockwave therapy group in respect to the final fascia thickness, and the VAS scale (p = 0.001). The differences between groups A and B showed that the shockwave group follow-up after 3 weeks experienced complete pain remission (1.0 ± 0.9; 95%CI 0.8-1.2) and after the 6-week follow-up, complete pain remission of plantar fasciitis was observed for both therapies. Patients had a better perception of the use of EWST at the end of the treatment, although in both groups it was satisfactory (p = 0.001).

CONCLUSIONS

The results of this study showed a shorter-term effectiveness of shockwave treatment compared with the use of iontophoresis. However, both techniques were effective in satisfactorily reducing pain in this short period.

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

Objectives

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

Patients and methods

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

Results

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

Conclusion

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

Posterior Tibial Artery Blood Flow Velocity Is Increased in Patients with Plantar Heel Pain

Background/Objectives: This study aimed to investigate the relationship between posterior tibial artery blood flow velocity and plantar heel pain (PHP). Methods: The PHP group comprised patients diagnosed with plantar fasciitis with plantar heel pain during gait, and the control group comprised healthy participants without plantar heel pain. The peak systolic velocity of the posterior tibial artery was measured using ultrasonography; it was measured three times on each side, and the mean value was calculated. Receiver operating characteristic curve analysis was performed to calculate the peak systolic velocity cutoff value for plantar heel pain. Results: 23 patients (age 58.0 ± 16.5 years; 13 males and 10 females) and 23 healthy participants (age 51.3 ± 17.3 years; 10 males and 13 females) formed the PHP and control groups, respectively. Peak systolic velocity on the affected side was significantly greater in the PHP group (44.1 ± 13.1 cm/s) than in the control group (32.7 ± 5.9 cm/s). No significant difference was observed between the left and right sides in the PHP (7.1 ± 9.8 cm/s) and control (3.7 ± 3.0 cm/s) groups. A cutoff value of 38.2 cm/s was observed on the affected side. Conclusions: We quantified the increase in posterior tibial artery blood flow velocity in patients with plantar heel pain. Peak systolic velocity measurements can aid in quantitatively evaluating these patients. This study was registered as a clinical trial (UMIN000046875) on 1 October 2021.

Efficacy of extracorporeal shockwave therapy, compared to corticosteroid injections, on pain, plantar fascia thickness and foot function in patients with plantar fasciitis: A systematic review and meta-analysis

OBJECTIVE

To compare the efficacy of extracorporeal shock waves versus corticosteroids injections on pain, thickness of plantar fascia and foot function in patients with plantar fasciitis. Secondarily, to assess the efficacy of radial and focused extracorporeal shock waves and the most appropriated intensity (high, medium or low).

DATA SOURCES

PubMed, SCOPUS, CINAHL and PEDro, until April 2024, according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

REVIEW METHODS

Randomized controlled trials comparing the efficacy of extracorporeal shock waves versus corticosteroids injections on pain intensity and sensitivity, thickness of plantar fascia and foot function in patients with plantar fasciitis. Methodological quality and risk of bias were assessed using PEDro Scale and Cochrane Risk of Bias Tool. Pooled effect was calculated using the standardized mean difference (SMD) and its 95% confidence interval (95%CI).

RESULTS

Sixteen studies involving 1121 patients, showing a mean of 6 points in PEDro scale, were included. At three months, extracorporeal shock waves were better than corticosteroids injections in reducing pain (SMD -0.6; 95%CI -1.1 to -0.11) and thickness of the plantar fascia (SMD -0.4; 95%CI -0.8 to -0.01) and increasing foot function (SMD 0.27; 95%CI 0.12-0.44). At six months, extracorporeal shock waves are more effective in reducing pain (SMD -0.81; 95%CI -1.6 to -0.06) and increasing foot function (SMD 0.67; 95%CI 0.45-0.89). Local pain and slight erythema were the most frequent adverse events.

CONCLUSIONS

Extracorporeal shock waves are a safe therapy, presenting more efficacy than corticosteroids injections in improving pain, thickness of plantar fascia and foot function at mid-term.

Efficacy of pharmacological and non-pharmacological therapies on pain intensity and disability for plantar fasciitis: a systematic review and meta-analysis

OBJECTIVE

To investigate the effects of pharmacological and non-pharmacological therapies on pain intensity and disability for plantar fasciitis.

DESIGN

Systematic review of randomised controlled trials (RCTs).

DATA SOURCES

AMED, MEDLINE, PEDro, Cochrane, SPORTDiscus, CINAHL, EMBASE and PsycINFO without language or date restrictions up to 3 February 2023.

ELIGIBILITY CRITERIA

RCTs that evaluated the efficacy of any pharmacological and non-pharmacological therapies compared with control (placebo, sham, waiting list or no intervention) on pain intensity and disability in people with plantar fasciitis. Two reviewers independently screened eligible trials, extracted data, assessed the methodological quality of included trials and assessed the certainty of the evidence using the Grading of Recommendations, Assessment, Development and Evaluations framework. Mean differences (MDs) with 95% CIs were reported.

RESULTS

Seventeen different therapies investigated in 28 trials were included in the quantitative analysis. For non-pharmacological therapies, moderate certainty evidence showed short-term effects of customised orthoses on pain intensity when compared with control (MD of -12.0 points (95% CI -17.1 to -7.0) on a 0-100 scale). Low certainty evidence showed short-term effects of taping on pain intensity (-21.3 (95% CI -38.6 to -4.0)). Long-term effects and effects on disability are still uncertain. For pharmacological therapies, low to very low quality evidence from few trials with small samples was inconclusive and supports that high-quality trials are needed.

CONCLUSIONS

Moderate-quality and low-quality evidence demonstrates customised orthoses and taping, respectively, reduce pain intensity in the short term in patients with plantar fasciitis.

Impact of Plantar Fasciitis on Foot-Specific and Generic Health-Related Quality of Life in King Khalid University Hospital, Saudi Arabia

Objectives The objective is to assess the extent of foot-specific and generic health-related quality of life (HRQoL) impairment among individuals diagnosed with plantar fasciitis (PF) at King Khalid University, Saudi Arabia, and to determine the influence of various sociodemographic and clinical factors. Methods In this cross-sectional study, we administered an online survey from March to June 2023 to patients with PF at King Khalid University Hospital. This questionnaire covered sociodemographic, and clinical characteristics, and included the translated Foot Health Status Questionnaire (FHSQ). Further, patient data were obtained from hospital records between 2016 and 2023 using the E-SIHI system. Results We recruited 209 patients for the study. Lower FHSQ scores were found in unemployed and low-income participants indicating a worse quality of life (QoL) in the Foot Pain domain, while those aged over 40 years and with low income showed greater impairment in the General Foot Health domain. No single factor influenced the Foot Function or Footwear domains. Worse General Health and Physical Activity scores were associated with low-education and low-income participants and those who did not exercise. Women exhibited a lower QoL than men in all domains except for General Health. Conclusion The QoL of Saudi women with PF was similar to that of women in other countries. However, the patients in the present study reported poorer footwear scores but better General Health scores. Therefore, focusing more on proper footwear-related treatments may help improve the QoL of patients with PF.

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.

Application of extracorporeal shock wave therapy in nervous system diseases: A review

Neurological disorders are one of the leading causes of morbidity and mortality worldwide, and their therapeutic options remain limited. Recent animal and clinical studies have shown the potential of extracorporeal shock wave therapy (ESWT) as an innovative, safe, and cost-effective option to treat neurological disorders. Moreover, the cellular and molecular mechanism of ESWT has been proposed to better understand the regeneration and repairment of neurological disorders by ESWT. In this review, we discuss the principles of ESWT, the animal and clinical studies involving the use of ESWT to treat central and peripheral nervous system diseases, and the proposed cellular and molecular mechanism of ESWT. We also discuss the challenges encountered when applying ESWT to the human brain and spinal cord and the new potential applications of ESWT in treating neurological disorders.

Biological response of extracorporeal shock wave therapy to tendinopathy in vivo (review)

Tendinopathy is a degenerative disease of the tendons caused by prolonged overstretching or overuse of the tendons. It accounts for a large proportion of musculoskeletal disorders which can occur in all age groups. The management of tendinopathy is typically conservative. In clinical practice, when other conservative treatments fail, extracorporeal shock wave therapy (ESWT) is normally used as an efficient alternative to surgical management. Several basic studies have shown that ESWT with lower energy flux densities can produce some biological responses in vivo to tendinopathy and may accelerate the initiation of the healing process in injured tendons. ESWT has a positive impact on the interactive chain of biological response, enhancing the signaling pathways of angiogenesis through mechanical conduction, and promoting cell proliferation and collagen formation. Finally, it helps tissue regeneration by controlling inflammation. The purpose of this review is to summarize the biological responses generated by ESWT in tendinopathy through a comprehensive review of the published literature. Although ESWT has been used clinically for the treatment of tendinopathies for nearly decades, less is known about the experimental studies of its biological effects on tendon tissue. Further studies on the biological response of ESWT for tendon injuries in vivo are needed in the future in order to provide better management to patients.

Molecular Mechanisms Underlying the Pain-Relieving Effects of Extracorporeal Shock Wave Therapy: A Focus on Fascia Nociceptors

In recent years, extracorporeal shock wave therapy (ESWT) has received increasing attention for its potential beneficial effects on various bone and soft-tissue pathologies, yielding promising outcomes for pain relief and functional recovery. In fact, ESWT has emerged as an alternative, non-invasive, and safe treatment for the management of numerous musculoskeletal disorders, including myofascial pain syndrome (MPS). In particular, MPS is a common chronic painful condition, accounting for the largest proportion of patients affected by musculoskeletal problems. Remarkably, sensory innervation and nociceptors of the fascial system are emerging to play a pivotal role as pain generators in MPS. At the same time, increasing evidence demonstrates that application of ESWT results in selective loss of sensory unmyelinated nerve fibers, thereby inducing long-lasting analgesia. The findings discussed in the present review are supposed to add novel viewpoints that may further enrich our knowledge on the complex interactions occurring between disorders of the deep fascia including changes in innervation, sensitization of fascial nociceptors, the pathophysiology of chronic musculoskeletal pain of MPS, and EWST-induced analgesia. Moreover, gaining mechanistic insights into the molecular mechanisms of pain-alleviating effects of ESWT may broaden the fields of shock waves clinical practice far beyond the musculoskeletal system or its original application for lithotripsy.
