An Evaluation of Shoulder External Rotation Braces

Purpose: The purpose of the present study was to evaluate 4 commercially available shoulder external rotation braces to determine their ability to achieve and maintain shoulder external rotation. In addition, for each brace, we collected patient-derived data on comfort level, ease of application, and ease of performing activities of daily living during brace wear. Methods: Four commercially available shoulder external rotation braces were evaluated for their ability to achieve and maintain external rotation in 12 healthy subjects. Results: Significant differences were noted between braces in their ability to achieve and maintain shoulder external rotation, as well as in their comfort ratings. Conclusions: We have shown that the commercially available shoulder external rotation braces evaluated in this study vary in (1) ability to achieve and maintain a desired position of external rotation of the shoulder, and (2) comfort ratings. Clinical Relevance: Selection of an external rotation brace should involve consideration of the device’s performance and comfort profile.
