The effects of hand splinting in patients with early stage thumb carpometacarpal joint osteoarthritis: a randomized, controlled study.Turk J Med Sci. 2020 Jun 15 [Online ahead of print]TJ
The evidence for the effectiveness of splinting in the thumb carpometacarpal osteoarthritis is limited. We aimed to evaluate the effects of the pre-fabricated carpometacarpal metacarpophalangeal immobilization splint on pain, hand function, and hand strength in patients with early stage thumb carpometacarpal osteoarthritis.
MATERIALS AND METHODS
Sixty-three hands with stage 1 or 2 thumb carpometacarpal osteoarthritis were enrolled in the study. The non-splint group received an oral information about how to accommodate daily activities. In addition, the splint group was given a pre-fabricated carpometacarpal metacarpophalangeal immobilization splint for 6 weeks. Pain was evaluated using the Australian/Canadian Osteoarthritis Hand Index (AUSCAN). Hand functions were evaluated using the AUSCAN and the Quick Disabilities of Arm, Shoulder and Hand (Q-DASH) questionnaire. Grip and pinch strengths were measured using a hydraulic dynamometer and a hydraulic pinch gauge.
The AUSCAN pain, stiffness, function, total scores and the Q-DASH scores were significantly decreased in the splint group compared to the non-splint group. Significant increments in grip and pinch strengths were detected in the splint group compared to the non-splint group.
The pre-fabricated carpometacarpal metacarpophalangeal immobilization splint is effective in improving pain, hand function, and hand strength in the patients with thumb carpometacarpal osteoarthritis.
