| Stroke has the characteristics of high morbidity,mortality,disability and recurrence rate.After stroke,70 %-80 % of patients with different levels of lower limb motor dysfunction,seriously affect the daily life of patients,to their families and society with a great burden.With the development of rehabilitation technology,mirror treatment joined with electromyography biofeedback treatment has received more and more attention in recent years.In addition,mirror treatment joined with electromyography biofeedback treatment has been proved to promote the recovery of upper limb function in stroke patients.With the development of rehabilitation technology,mirror treatment joined with electromyography biofeedback treatment has received more and more attention in recent years.Objective:To investigate the effect of mirror treatment joined with electromyograph-y biofeedback treatment on functional recovery of lower extremities in stroke patients with hemiplegia.Methods:1 Using random number table method,90 cases of stroke hemiplegia were divided into routine group,myoelectric group and combined group,30 cases in each group.2 Routine rehabilitation patients were given conventional rehabilitation therapy according to their own limb dysfunction,supplemented with pseudo-electro-biofeedback therapy and false-mirror treatment;EMG patients were supplemented with EMG biofeedback treatment and false-mirror on the basis of conventional rehabilitation therapy.Treatment;Patients in the combined group were supplemented with mirror treatment joined with electromyography biofeedback treatmenton the basis of conventional rehabilit-ation therapy.Before treatment and after 4 weeks of treatment,Fugl-Meyer motor function(FMA)lower extremities,Brunnstrom stage(lower extremities and foot),functional walking scale(FAC),and ankle dorsal extension activity were examined.The functional balance of lower extremities in each group was evaluated by the BES and the Barthel Index(MBI).Results:Brunnstrom's graded score: After 4 weeks of treatment,the routine group increased from 1.90±0.90 to 2.20±1.30,the myoelectric group increased from 1.83±1.03 to 3.23±0.94,and the combined group increased from 1.87±1.09 to 4.47± 0.63 points.FAC graded score: After 4 weeks of treatment,the routine group increased from 0.53±0.63 to 1.70±0.88,the myoelectric group increased from 0.63±0.81 to 2.20±0.79,and the combined group increased from 0.83±0.79 to 4.23± 0.82 points.Dorsal extensor muscle related muscle EMG score: After 4 weeks of treatment,the conventional group increased from the initial 27.53 ± 3.07?V to 30.67 ± 2.43?V,EMG increased from the initial 28.40 ± 3.42?V to 50.97 ± 6.39?V,combined The group increased from the initial 28.93 ± 1.51?V to 69.80 ± 4.90?V.FMA lower limb score: After 4 weeks of treatment,the routine group increased from the initial 14.17 ± 3.60 points to 20.30 ± 4.05 points,the EMG increased from the initial 10.70 ± 3.46 points to 17.17 ± 3.30 points,the combined group from the initial 11.37 ± 3.54 points to 18.93 ± 3.13 points.Ankle dorsiflexion active joint mobility: After 4 weeks of treatment,the conventional group increased from the initial 4.33 ± 1.84 ° to 9.63 ± 1.97 °,the EMG increased from the initial 5.07 ± 1.41 ° to 13.27 ± 1.98 °,and the combined group consisted of The initial 5.10 ± 1.21 ° increased to 15.37 ± 2.14 °.Berg balance score: 4 weeks after treatment,the conventional group increased from the initial 14.00 ± 11.46 points to 23.17 ± 12.94 points,the EMG increased from the initial 10.13 ± 13.30 points to 29.80 ± 10.89 points,the combined group from the initial 16.27 ± 12.20 Points increased to 37.43 ± 12.39 points.Modified Barthel index assessment: After 4 weeks of treatment,the conventional group increased from the initial 35.50 ± 13.79 points to 45.33 ± 12.79 points,the EMG increased from the initial 44.00 ± 19.76 points to 55.50 ± 18.35 points,the combined group from the initial 46.30 ± 23.11 points to 65.67 ± 17.40 points.There was no significant difference in the FMA scores of the lower extremities,ipsilateral iliac joint dorsiflexion,BBS,MBI score,FAC classification,hemiplegic lower limb Brunnstrom stage,and muscle strength associated with the dorsalis ulnaris muscle group in the three groups before treatment(P>0.05);After treatment,it was found that the above three indicators were significantly improved in the three groups of patients(P<0.05);Further comparisons found that after treatment,FMA scores of the lower extremities,ipsilateral ankle joint extension activity,BBS,MBI The scores,FAC classification,hemiplegic lower limb Brunnstrom stage,and myoelectric scores of the dorsalis ulnaris muscle were all significantly better than the conventional group.The differences between the two groups were statistically significant(P<0.05).The above-mentioned indexes of the combined group were also significantly better than the conventional group.Outstanding differen-ce can be identified between the conventional group and the myoelectric group(P<0.05).Conclusion:The results of this study show that mirror-image therapy combined with electromyographic biofeedback therapy is more effective than conventional rehabilitation therapy or electromyographic biofeedback therapy in the recovery of lower extremity function in patients with hemiplegia,the method is safe and effective. |
