Short-duration robotic therapy in stroke patients with severe upper-limb motor impairment.

摘要: Chronic motor deficits in the upper limb (UL) are a major contributor to disability following stroke. This study investigated effect of short-duration robot-assisted therapy on impairment, as measured by clinical scales and robot- derived performance measures patients with chronic, severe UL impairments after As part larger study, 15 indi- viduals paresis (Fugl-Meyer < 15) stroke (minimum 6 mo postonset) performed 18 sessions rehabilitation that consisted goal- directed planar reaching tasks over period 3 weeks. Out- come included Fugl-Meyer Assessment, Motor Power Wolf Function Test, Stroke Impact Scale, five robot-derived reflect control (aiming error, mean speed, peak mean:peak speed ratio, movement duration). Robot- assisted training produced statistically significant improve- ments from baseline posttreatment Assessment scores quality motion (quantified reduction aiming error dura- tion an increase ratio). Our findings indicate rehabili- tation can reduce impairment improve chronic
