Effects Of Virtual Reality Rehabilitation On Balance Ability In Patients With Pusher Syndrome After Stroke

Background and ObjectivePusher Syndrome(PS)is a serious posture control disorder that occurs during the recovery of brain injury.It manifests itself as a patient leaning towards the affected side in a variety of postures,including sitting,standing,and resisting corrections that shift body weight toward the body's midline or to a non-paralyzed side.5%to 63%of stroke patients exhibit pusher syndrome.Pusher syndrome severely affects the patient's ability to balance.Virtual Reality(VR)is a computer-generated artificial environment that gives people the feeling of being immersive.At present,virtual reality technology has been successfully integrated into many aspects such as medicine,psychology and rehabilitation,and has been proven to play a positive role in the treatment of disorders of balance caused by various neurological diseases.The purpose of this study was to observe the effect of rehabilitation training based on virtual reality technology on the degree of tilt,trunk control ability,balance function and depression status in stroke patients with pusher syndrome.MethodsStroke patients with pusher syndrome treated in the Department of Rehabilitation Medicine of the First Affiliated Hospital of Zhengzhou University from June 2017 to June 2019 were collected.After screening according to the inclusion and exclusion criteria,36 patients were enrolled.The patients were randomly divided into the control group and the experimental group using a sealed envelope method,with 18 persons in each group.The control group received routine balance training,while the experimental group received balance training of virtual reality,for 4 weeks.They were assessed with Burke Lateropulsion Scale,Berg Balance Scale,Sheikh's Scale of Trunk Control and Hamilton Depression Scale before and after training.ResultsAfter the intervention,the scores of the Burke Lateropulsion Scale,Berg balance scale,Sheikh's Scale of Trunk Control,and Hamilton depression scale improved in both groups after training(P<0.05).There were no significant differences in the scores of the Burke Lateropulsion Scale,Berg balance scale,Sheikh's Scale of Trunk Control,and Hamilton depression scale between the two groups before treatment(P>0.05).After 4 weeks of intervention,patients in the experimental group had better scores of Burke Lateropulsion Scale and Berg balance scale than in the control group(P<0.05).The score of Sheikh's Scale of Trunk Control and Hamilton Depression Scale of the experimental group was significantly better than the control group.(P<0.001).There was no significant difference in BLS scores between the left and right brain injury patients before and after intervention between the two groups(P>0.05).ConclusionCompared with the traditional balance training,rehabilitation training based on virtual reality technology can more effectively improve the degree of tilt,trunk control ability and balance function of stroke patients with pusher syndrome.And the patient's depression improved significantly.
