The aim of this study was to assess the correlation between perceived function (disability) and objectively measured loss of function (impairment), to understand what impairments are meaningful to patients.

We measured the perceived function with the visual analog scale, the 4-step rating scale (poor, fair, good, or excellent), and the Disabilities of the Arm, Shoulder, and Hand (DASH) score. The objective measurement of impairment included active range of motion at each joint, total active motion, grip strength, and 2-point discrimination.We also converted range of motion into 4 categories (poor, fair, good, and excellent) following guidelines from 3 different classification systems (American Society for Surgery of the Hand, Strickland-Glocovac, and revised Strickland). We used Spearman r and linear regression to assess the correlation.

Classification of angular measurement according to the tested systems does not reflect the patient’s perspective; it limits the precision of the measurement and adds little value to the measurement itself.
