| ObjectiveIn order to clarify the correlation between limb function and F wave in stroke patients with hemiplegia,the change rules of limb emg F wave in rehabilitation treatment were studied.so as to provide an important basis for the evaluation of early stroke rehabilitation treatment effect and prognosis.Methods50 patients with hemiplegia after stroke diagnosed by clinical symptoms and imaging examination were selected from the Department of neurorehabilitation of Zhengzhou second people’s Hospital from May 2017 to may 2018,and 50 healthy volunteers were selected as the control group for the detection of limb electromyography F wave parameters.Fugl Meyer scale(FMA)and Ashworth spasm scale(Ashworth)were used Before and after treatment,the motor function recovery of the affected side of the patients in the observation group was evaluated,and the correlation between the recovery of motor function of the affected side and F wave of EMG was compared and analyzed.Results1.Before rehabilitation treatment,the F wave amplitude and M wave amplitude of the affected side of the observation group were lower than those of the healthy side and the control group,and the difference was statistically significant(P<0.05);the threshold of the median nerve F wave of the affected upper limb of the observation group was higher.The difference between the healthy side and the control group was statistically significant(P<0.05),and the difference between the Fmean/M of the affected side and the healthy side and the control group was not statistically significant(P>0.05).2.Measured after 4 weeks of treatment,the F wave parameters of the affected side of the observation group were improved,but the M wave amplitude was still lower than that of the healthy side and the control group.The difference was statistically significant(P<0.05).The F wave amplitude,M wave amplitude,and Fmea/M value were higher than before treatment,the difference was statistically significant(P<0.05),and the F wave threshold after treatment was significantly lower than before treatment,the difference was statistically significant(P<0.05)).3.Measured after rehabilitation treatment,the MAS score and FMA score of the affected side of the observation group were significantly improved,compared with before treatment,the difference was statistically significant(P<0.05).4.Correlation analysis of the limb myoelectric F wave parameters and MAS and FMA scores of the patients in the observation group before and after rehabilitation treatment showed that the F wave amplitude,threshold and Fmean/M and MAS scores were correlated before rehabilitation treatment(r was 0.272,respectively),-0.645,0.441,P<0.05),and there is a correlation between each parameter and MAS score after treatment(r is 0.281,-0.576,0.439,P<0.05),where MAS score is related to F wave amplitude and Fmean/M It is positively correlated and negatively correlated with F wave threshold;F wave amplitude,threshold,Fmean/M and FMA scores are correlated before rehabilitation(r are 0.315,-0.702,0.483,P<0.05),and each parameter after treatment There is also correlation with FMA score(r is 0.296,-0.584,0.451,P<0.05).FMA score is positively correlated with F wave amplitude and Fmean/M,and negatively correlated with F wave threshold.Conclusion1.After rehabilitation treatment,the motor function of the affected limb of stroke hemiplegic patients has been significantly improved;2.The F wave amplitude of the hemiplegic limb after the early rehabilitationtreatment of stroke is significantly higher than before the treatment,while the threshold is lowered,indicating that the excitability of the motor nerve of the anterior spinal cord on the hemiplegic side is increased;3.There is a correlation between MAS and FMA scores and F waves,which play an important role in the evaluation of the rehabilitation effect of stroke hemiplegia. |
