The aim of this study was to investigate effects of elastic wrist orthoses on pain, grip strength, and function. Twenty-two women with seropositive rheumatoid arthritis (mean age, 53 years) registered their pain on a visual analogue scale both with and without orthosis on the wrist of the dominant hand in three standardized activities of daily living (ADL) situations. Grip force at onset of pain was measured on an electronic instrument (Grippit) with three different grips. Pain was decreased by 39%, 42%, and 52% when using an orthosis in the three ADL situations. Anecdotally, the women noted that the splints provided support and decreased pain both in home, at work, and during leisure activities. Orthoses improved grip force at onset of pain by 26%, 22%, and 29%. All subjects showed reduced strength (20%-25%) when compared to grip strength in a group of women without rheumatoid arthritis.
本研究的目的是调查弹性手腕矫形器对疼痛、握力和功能的影响。22名血清阳性类风湿性关节炎女性（平均年龄53岁），在三种标准化日常生活活动（ADL）情况下，分别在佩戴和不佩戴矫形器时，用视觉模拟量表记录优势手手腕的疼痛情况。在疼痛开始时，使用电子仪器（Grippit）通过三种不同握法测量握力。在三种ADL情况下使用矫形器时，疼痛分别减轻了39%、42%和52%。据这些女性称，夹板在家庭、工作和休闲活动中都提供了支撑并减轻了疼痛。矫形器使疼痛开始时的握力分别提高了26%、22%和29%。与一组无类风湿性关节炎的女性的握力相比，所有受试者的力量均降低了（20%-25%）。
