Abstract
OBJECTIVE
To assess the short-term effects of multimodal occupational therapy on pain and hand function in patients referred for surgical consultation due to carpometacarpal joint (CMC1) osteoarthritis (OA).
METHODS
In this randomized controlled trial, CMC1 OA patients referred for surgical consultation at three rheumatology departments were randomized to 3 months multimodal occupational therapy (including patient education, hand exercises, orthoses, and assistive devices) or usual treatment (OA information). Pain was measured on a numeric rating scale from 0-10 (0, no pain). Function included grip and pinch strength (Newtons), range-of-motion [palmar and CMC1 abduction (°); flexion deficit in digits 2-5 (mm)], and self-reported Measure of Activity Performance of the Hand (MAP-Hand; range: 1-4; 1, no activity limitation) and QuickDASH (range: 0-100; 0, no disability). Between-group difference was assessed with follow-up values as dependent variables and group as an independent variable, adjusted for baseline values and time to follow-up.
RESULTS
Among 180 patients (mean age 63 (SD 8) years; 81% women), 170 completed the short-term follow-up assessment (3-4 months after baseline). Compared to usual treatment, occupational therapy yielded significantly improved pain at rest (-1.4 [-0.7, -2.0], P < 0.001), pain following grip strength (-1.1 [-0.5, -1.7], P = 0.001), grip strength (23.4 [7.5, 39.3], P = 0.004), MAP-Hand (-0.18 [-0.09, -0.28], P = 0.001), and QuickDASH (-8.1 [-4.6, -11.5], P < 0.001).
CONCLUSION
The multimodal occupational therapy intervention had significant short-term effects on pain, grip strength, and hand function in patients with CMC1 OA.
