Abstract：Objective To explore the effect of exoskeleton rehabilitation robot combined with virtual reality treadmill training on the rehabilitation effect of limb motor dysfunction in patients with brain injury.Methods Totally 96 patients with brain injury admitted to Beijing Rehabilitation Hospital,Capital Medical University from March 2021 to March 2023 were selected as the study subjects by the convenience sampling method.They were divided into control group and observation group by the random number table method,with 48 cases in each group.The control group received routine rehabilitation intervention,while the observation group received exoskeleton rehabilitation robot combined with virtual reality treadmill training on the basis of the control group,both groups were intervened for one month.The joint range of motion,functional gait assessment(FGA)score,walking status,6 min walking test(6MWT)distance,Fugl-Meyer motor function assessment(FMA)score,Berg balance scale(BBS)score,and modified Barthel index(MBI)score were compared before and after the intervention in two groups.Results One month after intervention,the range of motion of shoulder joint abduction,hip joint abduction,and knee joint flexion in the two groups were all greater than those before intervention,and those in the observation group were greater than those in the control group(all P＜0.05);the observation group had higher gait speed and frequency than the control group,and shorter walking cycles,swing phase duration,and support phase duration than the control group(all P＜0.05);the 6MWT distance,FMA score,and BBS score of the two groups were longer/higher than those before intervention,and those in the observation group were longer/higher than those in the control group[(161±13)m vs(148±11)m,(72±4)vs(66±5),(41±5)vs(35± 5)](t=5.187,6.709,6.281,all P＜0.001).After 2 weeks and 1 month of intervention,the MBI scores of both groups were higher than those before intervention,and the observation group were higher than the control group[(69±3)vs(64±4),(81±3)vs(76±4)](t=5.827,7.811,both P＜0.001).Conclusion In the rehabilitation of limb motor dysfunction in patients with brain injury,exoskeleton rehabilitation robot combined with virtual reality treadmill training can improve the patients'limb mobility and the independent living ability,improve the movement posture,and promote the recovery of movement ability and walking ability.
