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.
