Approaches to optimize focused extracorporeal shockwave therapy (ESWT) based on an observational study of 363 feet with recalcitrant plantar fasciitis

Extracorporeal Shockwave Therapy for Foot and Ankle Disorders: A Systematic Review and Meta-Analysis

BACKGROUND

Extracorporeal shockwave therapy (ESWT) was first introduced into clinical practice in 1982 and has been a beneficial inclusion to the noninvasive treatment option of numerous orthopaedic pathologies. However, clinical evidence of the use of ESWT for various foot and ankle disorders has been limited with a consensus on its efficacy yet available. Therefore, the purpose of this study is to systematically review the literature, to provide a critical evaluation and meta-analysis for the use of ESWT in foot and ankle disorders.

METHODS

The PubMed and Embase databases were systematically reviewed and clinical studies that reported ESWT use for various foot and ankle disorders included.

RESULTS

A total of 24 clinical studies that included 12 randomized controlled trials and 12 case series were identified. Analysis of the evidence has indicated that ESWT can help manage plantar fasciitis, calcaneal spur, Achilles tendinopathy and Morton's neuroma. Meta-analysis of the change in pre- to post-VAS overall scores for plantar fasciitis significantly favored ESWT compared to placebo/conservative treatment with a MD -3.10 (95% CI, -4.36 to -1.83; I2 = 68%; P < 0.00001).

CONCLUSIONS

The current evidence has suggested that ESWT can provide symptomatic benefit to plantar fasciitis treatment, with minimal and unremarkable side effects. Overall, ESWT has been demonstrated to be a safe treatment option with a favorable complication profile. Further well-designed studies of ESWT for the treatment of calcaneal spurs, Achilles tendinopathy and Morton's neuroma are warranted to more soundly and safely support its current use. Future studies are suggested to investigate the optimization of ESWT treatment protocols.

Early-Application Extracorporeal Shockwave Therapy for Plantar Fasciitis in a Chiropractic Clinic: A Case Report

Objective

The purpose of this report is to describe the successful management of plantar fasciitis (PF) using only extracorporeal shockwave therapy.

Clinical Features

A 26-year-old male former athlete presented with insidious right posterior medial foot pain of 3 months' duration. He reported a past history of similar symptoms 12 years previously and was successfully treated with tape, ice, and electric stimulation. For the current episode, he attempted to manage with orthotics, motor nerve stimulation, and ice, and when that was insufficient, he sought care in our clinic. Initial history and evaluation found provocation of pain and functional limitations while wearing dress shoes, running, and playing basketball. Examination found palpatory tenderness at the medial aspect of the distal right calcaneus, and pain with right ankle dorsiflexion. Radiographs were unremarkable. Patient presentation and exam findings supported a working diagnosis of PF.

Intervention and Outcomes

Treatment was applied with a Richard Wolf WellWave low-energy shockwave therapy unit with focused dosage of 4000 shock pulsations at 10-mm depth to the site of pain. Treatment was applied 11 × over 5 weeks, after which the patient reported a complete resolution of pain and resumption of all activities.

Conclusion

Extracorporeal shockwave therapy appeared to be an effective treatment approach for the management of this patient's PF.

Current Concepts of Minimally Invasive Treatment Options for Plantar Fasciitis: a Comprehensive Review

PURPOSE OF REVIEW

Chronic foot pain constitutes a large portion of the chronic pain burden in the overall population. Plantar fasciitis is one of the most common and most easily identifiable causes of chronic foot pain. The syndrome has been estimated to cause 11 to 15% of foot pain visits, requiring professional care. Moreover, studies have suggested that 1 in 10 people will develop plantar fasciitis at some point in their life. Conservative management has been shown to be effective and considered first-line treatment. Minimally invasive treatment options are typically reserved for those who fail conservative management. With the advent of new techniques and improvements in current therapeutic options, there has been an expansion of available minimally invasive treatment options. The purpose of this review is to provide a comprehensive update on the current understanding of minimally invasive treatments of plantar fasciitis.

RECENT FINDINGS

This review shows that conservative management continues to be the first-line therapy, whereas other treatment options were those who failed conservative management using modern techniques that have shown improving effectiveness, with successful restoration of patient functionality, recovery, and satisfaction. However, a multitude of these minimally invasive treatment options are evolving.

CONCLUSION

While conservative management continues to be the mainstay of treatment for plantar fasciitis, multiple minimally invasive treatment options are emerging with potential effectiveness in reducing pain and improving the function.

Efficacy of foot orthoses for the treatment of plantar heel pain: a systematic review and meta-analysis

BACKGROUND

Plantar heel pain (PHP) is common. Foot orthoses are often applied as treatment for PHP, even though there is little evidence to support this.

OBJECTIVE

To investigate the effects of different orthoses on pain, function and self-reported recovery in patients with PHP and compare them with other conservative interventions.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

A systematic literature search was conducted in MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Web of Science, CINAHL and Google Scholar up to January 2017.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

Randomised controlled trials comparing foot orthoses with a control (defined as no intervention, sham or other type of conservative treatment) reporting on pain, function or self-reported recovery in patients with PHP.

RESULTS

Twenty studies investigating eight different types of foot orthoses were included in the review. Most studies were of high quality. Pooled data from six studies showed no difference between prefabricated orthoses and sham orthoses for pain at short term (mean difference (MD) of 0.26 (95% CI -0.09 to 0.60)). No difference was found between sham orthoses and custom orthoses for pain at short term (MD 0.22 (95% CI -0.05 to 0.50)), nor was there a difference between prefabricated orthoses and custom orthoses for pain at short term (MD 0.03 (95% CI -0.15 to 0.22)). For the majority of other interventions, no significant differences were found.

CONCLUSIONS

Foot orthoses are not superior for improving pain and function compared with sham or other conservative treatment in patients with PHP.
