Abstract

Objective The objectives of this study were to compare thumb combined abduction/index finger extension (hand opening) strength between subjects with carpometacarpal (CMC) osteoarthritis (OA) and normal controls and to assess the reproducibility of hand opening strength and abduction range of motion (ROM) measurements in patients with thumb CMC OA to establish the cutoff values scores for minimal detectable change. Methods Seventy-seven subjects, 96% female (age, 77 ± 7 years), participated in the study. The CMC OA group consisted of 39 patients (mean ± SD, 81 ± 7) and 38 healthy subjects (mean ± SD, 78 ± 6). Mixed models analysis of variance was conducted to determine the differences between groups. Results The post hoc testing revealed statistically significant differences in pain pressure threshold, opening strength, and ROM measurements within the CMC OA group as compared with the healthy group (all, P .05), except in case of opening strength (P 2 for pain pressure threshold, 0.12 to 0.13 lb for opening force, and 1.24 to 1.46 for abduction ROM measurement.
