A prospective randomized study comparing a forearm strap brace versus a wrist splint for the treatment of lateral epicondylitis

Background: The outcome is unknown for 2 common bracing treatments utilized for patients with lateral epicondylitis. The purpose of this study was to compare the clinical outcomes of a wrist splint with that of a counterforce forearm strap for the management of acute lateral epicondylitis. Materials and methods: Forty-two patients (44 elbows) received either a wrist extension splint (Group I-24 elbows) or a counterforce forearm strap (Group II-20 elbows). Measures on the Mayo Elbow Performance (MEP) and American Shoulder and Elbow Society (ASES) Elbow Assessment Form were collected prior to treatment and at 6 weeks. A total score was derived, utilizing the ASES Elbow Assessment, as was a score utilizing the standard scoring system for the MEP. Results: Group I's score derived from the ASES form improved 16 points and Group II's score improved 13 points. Group I's score on the MEP improved 13 points and Group II's score improved 12 points. There was no significant difference measured between the Groups with the ASES (P=.60) nor MEP (P=.63) scores. However, within the ASES derived score, pain relief was significantly better with the extension splint group (P=.027). No other variables were statistically significantly different. Discussion: Significant pain relief with the wrist extension splint may be due to improved immobilization of the wrist extensor muscles in a resting position. Conclusion: The wrist extension splint allows a greater degree of pain relief than does the forearm strap brace for patients with lateral epicondylitis.
