Clinical Research On The Effect Of Virtual Reality Technology Combined With Occupational Therapy Training On Upper Limb Function In Stroke Patients With Hemiplegia

1.BackgroundStroke is a disease of brain tissue damage which caused by intracranial blood circulation disorders.It can lead to many functional disorders,such as dyskinesia,sensation disorders,laloplegia and cognitive disorder.Upper limb motor dysfunction is one of the sequelae of stroke.At present,moter therapy is the main treatment for upper limb dysfunction after stroke.Although its clinical effect is clear and wide range of clinical applications,there are still the following deficiencies:l.Therapist are too much focus on the decomposition of the exercise,ignoring the integration of the movement;2.Motor training is boring,and is difficult for pateints to insisit;3.Most of assessment method are subjective,and it's difficult to quantify the therapeutic effect.Compared to traditional motor therapy,virtual reality technology compensates for the above deficiencies.It has three characteristics:immersive,interaction and imagine.It can create an interactive incentive environment for patients,stimulate the patient's sensory stimulation,and encourage patients to continue training.Tense and tedious mechanical rehabilitation training has become vivid and interesting,and then to improve the patient's ability to exercise and daily life,to help patients apply the exercise skills learned in training to better use in real life.This study hopes to use virtual reality technology combined with occupational therapy training to intervene in patients with upper limb dysfunction after stroke,and explore the clinical efficacy of combination therapy in post-stroke upper limb dysfunction.2.ObjectivesThe objectives of this experiment was to observe the effect of virtual reality therapy combined with occupational therapy on upper extremity motor function and activity of daily living in patients with stroke hemiplegia,so as to improve the clinical rehabilitation effect of such patients.3.Objects and methodsThe selected subjects were 30 patients with early stroke who were hospitalized in the Department of Rehabilitation Medicine in our hospital from September 2017 to January 2018.They were randomly divided into experimental group and control group with 15 cases each.In the experimental group,there were 11 males and 4 females,mean age was 49.73±17.73 years and an average course of disease was 95.53±44.96 days.In the control group,there were 9 males and 6 females,mean age was 52.13±18.17 years and average course of disease was 72.26±47.94 days.There was no significant difference in the basic information between the two groups(P>0.05).Evaluate the upper limbs of the two groups using the simplified Fugl-Meyer Upper Extremity Motor Function Rating Scale(FMA-UE)and the Hong Kong version of the hemiplegic upper limb function test(FTHUE-HK)and the Barthel Index(BI)before treatment and after 4 weeks of treatment.Motor function and daily living ability were used to measure the recovery of upper limb function.Two groups of patients were given conventional drugs and traditional exercise therapy.And the control group was asked to take occupational therapy for 50 minutes a day,5 times a week,and 4 weeks for one treatment period.Compare to other two groups,the experimental group were asked to take BioMaster and Flextable virtual reality therapy in addition,the training time consisted of 20 min of occupational therapy and 30 min of BioMaster and Flextable virtual reality therapy,50 minutes each day,5 times a week,a total of 4weeks of treatment.4.StatisticaI methodsSPSS24.0 statistical software was used for data processing.Independent sample t-test was used for comparison between the two groups.Paired t-test was used in the group before and after treatment.The difference was statistically significant at P<0.05.5.ResultsBefore treatment,the two groups of patients with basic information,FMA-UP,FTHUE-HK,BI is not statistically significant difference(P>0.05).After 4 weeks of treatment,the FMA-UE score and FTHUE-HK grading of the two groups were significantly higher than before treatment(P<0.05),and the experimental group was superior to the control group(P<0.05),while the Barthel was the two groups of patients.Although the index was significantly higher than before treatment(P<0.05),there was no significant difference between the two groups after treatment in the BI score group(P>0.05).6.ConclusionVirtual reality technology combined with occupational therapy training can effectively improve the upper limb motor function in stroke patients with hemiplegia,but its efficacy in improving patients with ADL is uncertain.
