To explore the feasibility and assess the effect of a prefabricated soft thumb-base orthosis on pain, hand strength, and activity performance in persons with osteoarthritis of the CMC joint.
In this randomized controlled trial, 29 patients received hand exercises only (control group) and 30 patients received hand exercises and an orthosis (orthosis group). The primary outcome was pain, while secondary outcomes included grip and pinch strength, and self-reported symptoms and activity performance. Outcome assessments, and measures of grip strength and pain with and without orthosis in the orthosis group, were made after two months.
55 participants (mean age 70.5 years) completed all assessments. There were no significant differences between the groups in primary or secondary outcomes after two months. However, in the orthosis group, pain was significantly less when wearing the orthosis than when not wearing it. Participants reported that the orthosis felt uncomfortable during activities involving water and one-third wanted more support of the CMC joint.
A soft prefabricated orthosis seems to have an immediate pain-relieving effect during use, but no effects in terms of less hand pain, or improved strength or activity performance when not worn.
探讨预制软质拇指基部矫形器对第一掌指关节骨关节炎患者疼痛、手部力量和活动表现的可行性及效果评估。
在这项随机对照试验中，29名患者仅接受手部锻炼（对照组），30名患者接受手部锻炼并佩戴矫形器（矫形器组）。主要结局指标为疼痛，次要结局指标包括握力和捏力，以及自我报告的症状和活动表现。两个月后进行结局评估，以及矫形器组佩戴和不佩戴矫形器时的握力和疼痛测量。
55名参与者（平均年龄70.5岁）完成了所有评估。两个月后，两组在主要或次要结局指标上无显著差异。然而，在矫形器组中，佩戴矫形器时的疼痛明显低于不佩戴时。参与者报告称，在涉及水的活动中，矫形器感觉不舒服，三分之一的人希望第一掌指关节得到更多支撑。
预制软质矫形器在使用过程中似乎有即时缓解疼痛的效果，但在不佩戴时，对手部疼痛减轻、力量增强或活动表现改善方面没有效果。
