Randomized Controlled Trial Comparative StudyPhysical therapy, corticosteroid injection, and extracorporeal shock wave treatment in lateral epicondylitis. Clinical and ultrasonographical comparison.
The aim of this study was to compare--clinically and ultrasonographically--the therapeutic effects of physical therapy modalities (hot pack, ultrasound therapy, and friction massage), local corticosteroid injection, and extracorporeal shock wave treatment (ESWT) in lateral epicondylitis (LE). Fifty-nine elbows of 59 patients with LE were randomized into three treatment groups receiving either physical therapy, a single corticosteroid injection, or ESWT. Visual analogue scale (VAS) was used to assess pain intensity, Jamar hydraulic dynamometer for grip strength, finger dynamometer for pinch strength (before treatment, on the first, third, and sixth months of treatment). ⋯ We imply that physical therapy modalities, corticosteroid injection, and ESWT have favorable effects on pain and grip strength in the early period of LE treatment. The increase in grip strength lasts longer with ESWT. On the other hand, ultrasonographic findings do not change in the first six months of these treatment methods.
