Background: Lateral epicondylitis is one of the most common causes of elbow pain. It is generally observed in people between the ages of 40 and 50 years, and the dominant extremity is more frequently affected. Various noninvasive methods are frequently used; however, studies investigating the effectiveness of the orthoses are limited and with controversial outcomes. Objective: To investigate the effectiveness of a hand-wrist resting orthosis and an epicondylitis bandage in lateral epicondylitis. Study design: Randomized controlled trial. Methods: In total, 82 patients diagnosed with unilateral lateral epicondylitis were enrolled into the study. Hand-wrist resting orthosis was applied to 45 patients and epicondylitis bandage was applied to 41 patients. Patients were evaluated before treatment and at 6 weeks after treatment with a Visual Analogue Scale; Disabilities of the Arm, Shoulder, and Hand questionnaire; the Short Form 36; and a determination of hand grasping force. Results: Both groups were similar in terms of age, body mass index, gender, frequency of lateral epicondylitis on the dominant side, dominant extremity, and duration of complaints (p > 0.05). A statistically significant recovery was detected in both groups between the pre-therapy values and the values at the sixth week in terms of Visual Analogue Scale scores; Disabilities of the Arm, Shoulder, and Hand questionnarie scores; hand grasping forces; and the Short Form 36 mental and physical component scores (p < 0.05). However, there were no significant differences detected between the two therapy methods before the therapy and at the sixth week of treatment in all parameter values (p > 0.05). Conclusion: Our results suggest that both epicondylitis bandage and hand-wrist resting orthosis are effective treatment options for lateral epicondylitis–induced pain, functional status, muscle strength, and quality of life. Furthermore, neither treatment option was superior to the other. Large, randomized studies are necessary for more clear statements. Clinical relevance: Epicondylitis bandage and hand-wrist resting orthosis are equally effective treatment options for lateral epicondylitis–induced pain, functional status, muscle strength, and quality of life.
