DASH Scores After Myoelectric Arm Orthosis Use at Home in Chronic Stroke

The study objective was to retrospectively evaluate the outcomes and clinical benefits provided by the MyoPro myoelectric powered elbow-wrist-hand arm orthosis in individuals 65 and older with upper limb impairment secondary to a stroke. The Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire was administered to individuals who have chronic stroke both before and after receiving their myoelectric orthosis. A Generalized Estimating Equations model was analyzed. After using the MyoPro, 19 individuals with chronic stroke had a mean improvement in DASH score of 18.07, 95%CI=(-25.41, -10.72), adjusted for nine covariates. This large change in DASH score was statistically significant and clinically meaningful, as participants self-reported an improvement with engagement in functional tasks.

本研究旨在回顾性评估MyoPro肌电驱动式肘腕手臂矫形器为65岁及以上因中风导致的上肢功能障碍患者提供的治疗效果及临床益处。对慢性中风患者，在佩戴肌电矫形器前后均进行了上肢、肩部和手部功能障碍（DASH）问卷的评估。通过广义估计方程模型进行了分析。使用MyoPro后，19名慢性中风患者的DASH评分平均提高了18.07分，95%置信区间为（-25.41，-10.72），调整了九个协变量。这种DASH评分的显著变化不仅在统计学上具有显著性，而且在临床意义上也具有重要意义，因为参与者报告在参与功能性任务时有所改善。
