The utilization and effects of filiform dry needling in the management of tendinopathy: a systematic review.

Tendinopathy is frequently associated with pain, soft tissue impairments and muscle performance limitations. Dry needling (DN) incorporates a fine filiform needle to penetrate the skin and underlying soft tissue in an effort to decrease pain and improve function. While injectable interventions and gauged-needle tendon fenestration for tendinopathy has been reviewed, DN for tendinopathy has yet to be synthesized. To systematically review the utilization and effects of DN for tendinopathy. Six electronic databases (PubMed, CINAHL, Scopus, SportDiscus, PEDro and the Cochrane Library) were searched from inception through August 15, 2020, using appropriate keywords and relevant synonyms. After screening 462 articles, 10 studies met inclusion criteria. Study designs included case reports, case series, and randomized clinical trials. DN was used in isolation in 3/10 studies and as part of a multimodal approach in 7/10 studies. DN was associated with improved pain, function, muscle performance and perceived improvement in each study evaluating the relevant outcome. Conflicting results were found in comparative studies evaluating DN. DN may be a useful adjunctive treatment in the conservative management of tendinopathy, although its discrete effect is unclear. Very Low-quality evidence and methodological limitations suggest further investigation is warranted. [ABSTRACT FROM AUTHOR]
