Zusammenfassung:	Abstract Iwamuro BT, Cruz EG, Connelly LL, Fischer HC, Kamper DG. Effect of a gravity-compensating orthosis on reaching after stroke: evaluation of the Therapy Assistant WREX. Objective To evaluate the effectiveness of an upper-extremity orthosis to improve the reaching workspace of stroke survivors. Design Within-subjects repeated-measures design evaluating reaching with and without the Therapy Assistant Wilmington Robotic Exoskeleton (WREX). Setting Laboratory. Participants Stroke survivors (N=10) with chronic upper-extremity hemiparesis. Interventions Not applicable. Main Outcome Measures Arm movement kinematics (Optotrak Certus motion detection system), muscle activity for biceps, triceps, anterior deltoid, and brachioradialis muscles (bipolar surface electromyography). Results Significant improvements of reaching distance occurred for all subjects across all targets ( P
