Efficacy of a forearm band in addition to exercises compared with exercises alone for lateral epicondylitis: A...

A forearm band is frequently used for lateral epicondylitis worldwide. However, evidence regarding its efficacy has been insufficient. The objective of this prospective, randomized, controlled trial was to analyze the effects of a forearm band for treatment of lateral epicondylitis at 1, 3, 6, and 12 months.

Patients with lateral epicondylitis were randomly allocated into a band (n = 55) or non-band (n = 55) group. Patients in the band group were instructed to wear a forearm band for more than 6 h daily for at least 6 months. Patients in both groups were instructed to perform wrist extensor stretching exercises for 30 s, 3 times daily, for 6 months. Hand10, pain, and satisfaction scores, and proportions of positive physical examinations, including tenderness assessment, Thomsen test, and middle finger extension test, were evaluated at 1, 3, 6, and 12 months after enrollment.

There were no significant differences between the band and non-band groups with regard to Hand10, pain, or satisfaction scores at 1, 3, 6, and 12 months. Likewise, there was no significant difference in proportions of positive physical examinations between groups at 1, 3, 6, and 12 months.

The results of the current study suggest that a forearm band may have no more than a placebo effect, and do not support the use of a forearm band based on its effectiveness.
