Recently, radial shock wave has been shown to be effective in the treatment of chronic musculoskeletal pain, including calcific tendinitis, epicondylitis, and plantar fasciitis. The energy and pressure produced by radial shock wave is focused on the treated musculoskeletal tissue. The mechanism of action has been hypothesized that the energy could result in analgesic effect and stimulation of angiogenesis and healing response and then relief of the symptoms. The effectiveness of radial shock wave on treatment of myofascial pain was reported by Jeon and colleagues in 2012.
