The Effects Of Sensory-driven Hand Robot Training On Finger Function Recovery In Stroke Patients

Objective:By observing the clinical effect of sensory-driven hand function robot training on the finger function of stroke patients,we provide the basis for the clinical application and promotion of hand function robots.Methods:A total of 43 patients with post-stroke hand dysfunction who were hospitalized in the Department of Rehabilitation Medicine of the First Hospital of Jilin University from September 2021 to March 2022 and met the inclusion criteria were collected.They were randomly divided 22 cases in the experimental group and 21 cases in the control group（including 2 cases drop-out in the experimental group and 1 case drop-out in the control group）.Finally,40 cases were completed,among which are 20 cases in the experimental group and 20 cases in the control group.Both groups received 40 min conventional rehabilitation training.Based on this,the control group received 20 min hand function training assisted by therapists,and the experimental group received 20 min sensory-driven hand function robot training,once a day,5 days a week,and totally 4 weeks.Scales such as optimized Fugl-Meyer and Lindmark Assessment（FLA）,Modified Ashworth Scale（MAS）,grip strength,Range of Motion（ROM）,Fugl-Meyer Motor Function Assessment（FMA）hand motor part,Wolf Motor Function Test（WMFT）,and Barthel Index（BI）were adopted to evaluate all patients before and after treatment to observe the recovery of hand function.Result:Before treatment,in FLA,MAS,grip strength,ROM,FMA（part of hand motor）,WMFT and BI score,the difference was not statistically significant（P>0.05）,indicating comparability.Intra-group comparison: after treatment,FLA,grip strength,AROM,FMA（hand motor part）,WMFT and BI score of patients in the experimental group had statistically significant differences（P<0.05）,and the score after treatment was significantly higher than that before treatment,while there was no significant difference in MAS before and after treatment（P>0.05）.Compared with pre-treatment,the control group had statistically significant differences after treatment in FLA,grip strength,AROM,FMA（part of hand motor）,WMFT and BI score（P<0.05）,but there was no significant difference in MAS before and after treatment（P>0.05）.Comparison between the two groups: after treatment,FLA,grip strength,AROM,FMA（part of hand motor）,WMFT,BI score in the treatment group were better than those in the control group,the differences were statistically significant（P<0.05）.In the sub-item analysis of AROM,the treatment group was significantly better than the control group in the total AROM of thumb,middle and ring fingers,the total of AROM in flexion of five fingers and the AROM of five fingers.The differences were statistically significant（P<0.05）.In the sub-item analysis of FMA（part of hand motor）,the treatment group was better than the control group in opposition,cylindrical grasping and spherical grasping,and the differences were statistically significant（P<0.05）.Conclusion:Sensory-driven hand function robot training can effectively promote the recovery of hand sensory function in stroke patients;Sensory-driven hand function robot training can significantly improve the strength of the affected-side finger muscles in stroke patients,and promote the recovery of finger motion range.In the thumb,middle and ring fingers especially,the effect is better than the control group.Sensory-driven hand function robot training can effectively improve the motor function of upper limbs and fingers of patients.Compared with conventional function rehabilitation training,it is more effective in opposition,cylindrical grasping and spherical grasping.In terms of improving the activities of daily living of stroke patients with hemiplegia,sensory-driven hand functional robot training has more obvious effects than hand functional training.
