An evaluation of shoulder external rotation braces.

Abstract

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. Four commercially available shoulder external rotation braces were evaluated for their ability to achieve and maintain external rotation in 12 healthy subjects. Significant differences were noted between braces in their ability to achieve and maintain shoulder external rotation, as well as in their comfort ratings. 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. Selection of an external rotation brace should involve consideration of the device's performance and comfort profile.
