Reliability of isometric wrist extension torque using the LIDO WorkSET for late follow-up of postoperative wrist patients.
The objectives of this study were to determine interobserver, intraobserver, and overall reliability of isometric wrist extension torque using the LIDO WorkSET and then to estimate the minimal level of detectable change using the standard error of measurement. A generalizability study was conducted on 18 postoperative patients. Primary outcome was mean torque of three trials. Variance components were used to calculate generalizability coefficients for intraobserver (G = 0.96), interobserver (G = 0.94), and overall reliability (G = 0.92). When the same therapist is evaluating a patient on different days, a change of more than 16 inch-lb is needed to be 90% confident that true change has occurred. A greater value for change (23 inch-lb) is required when different therapists evaluate a patient on different days. The LIDO WorkSET measures wrist torque in a reproducible manner in an applied setting. The testing protocol is sensitive to differences in wrist torque between individuals and tolerated in the late postoperative period.
