摘要

OBJECTIVE: To determine the effect of a wrist orthosis on work performance, hand dexterity, and pain during task performance, 40 individuals with rheumatoid arthritis were studied using a 2 period, crossover design. METHODS: Each patient was fitted with a Futuro wrist orthosis. Dexterity was measured with and without the orthosis using the Jebsen Hand Function Test. Work performance was assessed using 2 tasks (one simulating the use of shears, the other the use of a screwdriver) on a work simulator. All tasks were performed both with and without the orthosis, with the order of orthosis versus no orthosis randomly assigned. Pain before and after performing tasks was assessed using a 10 cm horizontal visual analog scale. RESULTS: While on the screwdriver task work performance was less with the orthosis (p = 0.0002); on the shears task there was no significant difference in work performance with and without the orthosis. The average pain after performing both tasks was significantly less with the orthosis on. A 2 factor analysis of variance model with repeated measures suggested that taking into account the reduced work performance during splint wear, pain was still significantly reduced with splint wear. The average time to complete all 7 tasks on the Jebsen Hand Function Test was longer when the subjects wore the splint compared to when they did not (62.0 vs 57.6 s, respectively; p = 0.0086). CONCLUSION: The results suggest that the effect of splint wear on work performance is highly task specific, and thus the ergonomic demands of the individual's daily life must be considered if a splint is to provide maximal effectiveness.
