Robot-based hand motor therapy after stroke

摘要: Robots can improve motor status after stroke with certain advantages, but there has been less emphasis to date on robotic developments for the hand. The goal of this study was determine whether a hand-wrist robot would function, and evaluate specificity therapy effects brain reorganization. Subjects chronic producing moderate right arm/hand weakness received 3 weeks that emphasized intense active movement repetition as well attention, speed, force, precision timing, included virtual reality games. initiated hand movements. If necessary, completed movements, feature available at all visits seven subjects latter half six subjects. Significant behavioural gains were found end treatment, example, in Action Research Arm Test (34 +/- 20 38 19, P< 0.0005) arm Fugl-Meyer score (45 10 52 10, P < 0.0001). Results suggest greater receiving assistance sessions compared those sessions. grasp task practiced during therapy, when performed functional MRI, showed increased sensorimotor cortex activation across period while non-practiced task, supination/pronation, did not. A robot-based improvements function stroke. Reorganization maps current task-specific, finding useful considering generalization rehabilitation therapy.
