Clinic Research On Robot-assisted With Virtual Reality Technology For Upper Limb Motor Function And Activity Ability After Stroke

ObjectiveTo study the effect of robot-assisted training combined with virtual reality technology(VR)for hemiplegic upper limb motor function and activity ability with post-stroke.Further analyses Correlation Between motor function and activity ability.MethodsWe choosed 40 patients who were conformed to the inclusion criteria of post-stroke hemiplegic upper limb dysfunction.They were randomly divided into the treatment group and the control group.Every patients received the same basic treatment,including drug therapy and exercise treatment.The treatment group was treated by the robot-assisted training combined with virtual video games.And the control group was treated by conventional occupational therapy.Both groups were treated for 2 weeks,one time a day.a total of 12 times and every time for 30 minutes.Every patients were assessed before and after the training by motor function and activity ability.The assessment of motor function includes Brunnstrom atage?Fugl-Meyer score.The assessment of activity ability includes Modified Barthel index(MBI)?Motor activity log(MAL)and Upper extremity functional index(UEFI).Results1.Improvements in Brunnstrom stage of upper arm and hand?FM score of upper arm ?wrist and total score of FM were significantly higher than before in the treatment group(P < 0.05).Improvements in Brunnstrom stage of hand?FM score of upper arm?and total score of FM were significantly higher than before in the control group(P<0.05).Improvements in FM score of upper arm and total score of FM were significantly greater following the robot-assisted training combined with VR training than the conventional occupational therapy(P<0.05).2.Significant increases in MBI score?UEFI and MAL score(including Amount of use and Quality of movement)were found in both groups after the treatment(P<0.05).Improvements in AOU and QOM were significantly in the treatment group than the control group(p<0.05).3.Motor function had positive correlations with the activity ability.AOU score had low positive correlations with FM score of upper arm?wrist?hand and total score of FM.QOM and UEFI had significantly positive correlations with FM score of upper arm?hand and total score of FM.MBI had low positive correlations with FM score of hand and weak correlations with FM score of upper arm?wrist and total score of FM.4.Significant increases were found in MBI in both group after one month follow-up.Improvements in MBI were significantly in the treatment group than the control group after one month follow-up(P<0.05).Conclusion1.Both groups are benefited in upper limb motor function and activity ability of post-stroke by the intervention.2.Improvements in motor function?amount of use and quality of movement of hemiplegic upper limb and hand after stroke by robot-assisted training combined with VR were better than conventional occupational therapy.And have a certain forward effect in activity of daily life.3.Rehabilitation could improve motor function and activity ability of hemiplegic upper limb and hand after stroke.And they had significantly positive correlations with each other.
