Low level laser therapy can be effective for tendinitis: a meta-analysis.
Bjordal J M.
A literature search identified 77 randomized clinical trials with LLLT, of which 18 included tendinitis. Three trials were excluded for lack of placebo control, of which one was comparative, another lacked patients with tendinitis in the treatment group, while the last unwittingly gave the placebo group active treatment. Four trials used too high power density or dose, and three did not expose the skin directly overlying the injured tendon. The remaining eight trials were included in a statistical pooling, where the mean effect of LLLT over placebo in tendinitis was calculated to 29.5% (19.5-39.0). LLLT with optimal treatment procedure/parameters can be effective in the treatment of tendinitis.
