Objective To study the effects of the rehabilitation robot-assisted task-oriented training on the hand function in patients after stroke. Methods From June, 2015 to September, 2016, 35 inpatients suffering from stroke were randomly allocated to control group (n=17) and trial group (n=18). Based on the routine rehabilitation, the trial group accepted robot-assisted task-oriented training, while the control group accepted therapist-assisted task-oriented training, for two weeks. They were measured the active range of motion (AROM) of fingers, assessed with fingers motor of Fugl-Meyer Assessment (FMA) and modified Barthel Index (MBI) invovled with hands before and after train-ing. Results The inpatients dropped three in the control group, two in the trial group. AROM of extension and flexion of all the fingers, the AROM of extension and total of three fingers of thumb, index and middle, and the total AROM of each finger improved in the trial group af-ter training (t>2.937, P<0.05), while the AROM of extension and flexion of all the fingers, AROM of extension, flexion and total of the fin-gers of thumb, index and middle, total AROM of the fingers of thumb, index and little improved in the control group after training (t>2.528, P<0.05);the AROM of extension and total of the fingers of thumb, index and middle, and the total AROM of fingers of thumb and index im-proved more in the trial group than in the control group (t>2.535, P<0.05). The scores of mass flexion, mass extension, opposition, cylinder grip, spherical grip and total score of FMA improved in the trial group after training (Z>2.000, P<0.05), while the scores of mass extension, opposition and the total score of FMA improved in the control group after training (Z>2.000, P<0.05). There was no significant difference between the two groups on the items and total scores after training (P>0.05). The scores of feeding, dressing, toilet transfers, bathing, groom-ing of MBI and the total score of them improved in the trial group after training (Z>2.041, P<0.05), while the total score of MBI improved in the control group after training (Z=-2.527, P<0.05). There was no significant difference between the two groups in the items and total scores after training (P>0.05). Conclusion The rehabilitation robot-assisted task-oriented training can improve AROM of hemiplegic fingers and grip function.
