To investigate the effect of 3 commercial wrist orthoses on finger dexterity and hand function of patients with rheumatoid arthritis (RA).
Forty-two patients with definite RA participated in the cross-over study comparing 3 styles of commercial wrist orthoses. Finger dexterity and hand function of the dominant hand were assessed while splinted and unsplinted, at the initial session and after 1 week of intermittent orthosis use. Finger dexterity was assessed using two subtests from the Purdue Pegboard Test (Purdue) and hand function was assessed using the Jebsen-Taylor Hand Function Test (Jebsen-Taylor).
Both finger dexterity and hand function were reduced by splinting; men and women were affected similarly. There was no difference in finger dexterity or hand function afforded by the 3 orthoses. Results on both the Purdue and Jebsen-Taylor tests showed a significant learning effect across time.
The 3 commercial wrist orthoses studied reduce dexterity similarly and significantly. When commercial wrist orthoses are to be used during tasks that require maximum dexterity, this reduction should be weighed against the known benefits of splinting.
探讨3种市售腕关节矫形器对类风湿关节炎（RA）患者手指灵活性和手部功能的影响。
42例确诊为RA的患者参与了一项交叉研究，比较3种市售腕关节矫形器。在初次就诊时以及间歇性使用矫形器1周后，分别评估戴矫形器和不戴矫形器时优势手的手指灵活性和手部功能。手指灵活性采用普渡钉板试验（Purdue）的两个子测试进行评估，手部功能采用杰布森 - 泰勒手部功能测试（Jebsen - Taylor）进行评估。
佩戴矫形器会降低手指灵活性和手部功能；男性和女性受影响程度相似。3种矫形器在手指灵活性或手部功能方面没有差异。普渡试验和杰布森 - 泰勒试验的结果均显示，随着时间推移存在显著的学习效应。
所研究的3种市售腕关节矫形器对手指灵活性的降低程度相似且显著。当在需要最大灵活性的任务中使用市售腕关节矫形器时，应将这种灵活性降低与已知的矫形器益处相权衡。
