Abstract
ABSTRACT
Introduction
Rheumatoid arthritis (RA) causes structural damage that causes joint deformity including metacarpophalangeal (MCP) joint ulnar drift (UD), thus hindering the pinch strength and the functional ability of the hand. Orthosis or splints are designed to maintain the hand’s function, improve joint alignment, restore biomechanical balance, and reduce tissue stress. Limited studies have been done on the effects of dynamic splint on pinch strength and functional ability. Therefore, the purpose of this study was to evaluate and quantify the effects of dynamic MCP splint in treatment of ulnar deviation of RA on pinch strength and functional ability in women.
Methods
Twenty women with RA were recruited and completed a 4-week intervention period with dynamic MCP splint. Pinch strength and functional ability score were measured at baseline and after 4 weeks.
Results
The results showed a significant improvement in pinch strength (mean ± SD, 11.68 ± 2.14 to 13.53 ± 2.14; P = 0.000) and functional ability score (mean ± SD, 22.70 ± 9.12 to 19.70 ± 8.14; P = 0.000).
Conclusion
The results of this study show that the dynamic MCP splint had a positive impact on rheumatoid hands that align the joints in their functional position. The dynamic MCP splint improved the mechanical stability of the hand, thus reducing pain and stress on joints, which in turn improves the pinch strength and functional ability of rheumatoid hand.
Clinical Relevance
To increase patient acceptance and use of the splint, the splint designed and used in this study was compact and only covered the affected areas and joints of the hand. Because there was no involvement of the wrist joint and the fingertips were free, the splint was lightweight and allowed the patient to perform activity while wearing it.
