Effectiveness of extracorporeal shockwave therapy in treatment of upper and lower limb tendinopathies: A systematic review and meta-analysis

BackgroundTendinopathy is caused by repetitive motion, excessive stress on the tendon, overstretch, and motion past the critical angle of rotation or translation. There are various treatment options available for tendinitis, including those affecting both the upper and lower limbs and those of calcific and non-calcific types. Hypothesis/purposeFew reviews have analyzed the efficacy of Extracorporeal Shockwave Therapy (ESWT) in treating upper and lower limb tendinopathies while considering calcific and non-calcific-type tendinitis. This paper provides a review and meta-analysis on Randomized Controlled Trials (RCTs), which compared results from a group undergoing ESWT treatment to another group under different treatments. Study designSystematic review and meta-analysis. MethodsA systematic search was conducted on PubMed, Web of Science, Embase, the Cochrane Central Register of Control Trials (CENTRAL), and Physiotherapy Evidence Database (PEDro) databases for articles published up to January 2022. The reference lists of identified articles were further scanned. Twenty-two studies were included in the meta-analysis. ResultsMeta-analysis showed no difference in pain reduction in ESWT when compared with a comparison group at 4 (p = 0.26) and 12 weeks (p = 0.33). There were no differences in DASH scores at 12 months between the two groups (p = 0.32). ConclusionExtracorporeal Shockwave Therapy (ESWT) is effective when used to treat lower limb and calcific tendinitis. It does not yield any better results than other treatment options in managing upper limb tendinopathies and non-calcific tendinopathies.
