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肌电驱动肘腕手上肢矫形器（MyoPro myoelectric powered elbow-wrist-hand arm orthosis）在65岁及以上继发脑卒中所致上肢功能障碍患者中的应用结局与临床获益。研究对慢性脑卒中患者在佩戴该肌电矫形器前后均施行了上肢、肩与手功能障碍问卷（Disabilities of the Arm, Shoulder and Hand, 简称DASH）评估，并采用广义估计方程模型（Generalized Estimating Equations model）开展统计分析。结果显示，19名慢性脑卒中患者在使用MyoPro后，DASH评分平均改善18.07分，95%置信区间(95%CI)为(-25.41, -10.72)，该分析校正了9项协变量。DASH评分的这一显著变化兼具统计学意义与临床价值，受试者自述其参与功能性任务的能力得到了改善。
