To assess the effectiveness of a functional splint for trapeziometacarpal osteoarthritis.
Forty patients with a diagnosis of painful trapezio-metacarpal osteoarthritis of the dominant hand were randomized into 2 groups. The study group received the splint at baseline and used it during activities of daily living for 180 days and the control group used the splint only during the evaluations for the first 90 days and during activities of daily living for the following 90 days. Pain, strength, hand function and dexterity (with and without splint) were measured by a blinded assessor at baseline, 45, 90 and 180 days.
The groups were homogenous at baseline for all outcomes evaluated. Pain without the splint was significantly different between groups over time; the study group experienced a decrease in pain beginning with the first evaluation (45 days), whereas the control group achieved a lower pain score only at the end of the study, after having used the splint for 90 days. No significant differences between groups were found for the other parameters.
Splint use during activities of daily living for patients with trapeziometacarpal osteoarthritis reduces pain, but does not alter function, grip strength, pinch strength or dexterity.
评估功能性夹板治疗腕掌关节骨关节炎的疗效。
40 名被诊断为手部优势侧疼痛性腕掌关节骨关节炎的患者随机分为 2 组。研究组在基线时佩戴夹板，并在 180 天的日常生活活动中使用它，对照组仅在第 90 天的评估和随后的 90 天的日常生活活动中使用夹板。由盲法评估者在基线、45 天、90 天和 180 天时测量疼痛、力量、手部功能和灵巧度（有无夹板）。
两组在所有评估的结局上基线时均具有同质性。不使用夹板时的疼痛在组间随时间有显著差异；研究组从第一次评估（45 天）开始疼痛就有下降，而对照组仅在研究结束时，即使用夹板 90 天后才达到较低的疼痛评分。其他参数在组间没有发现显著差异。
对于腕掌关节骨关节炎患者，在日常生活活动中使用夹板可减轻疼痛，但不能改变功能、握力、捏力或灵巧度。
