A Comparative Study On The Therapeutic Effects Of Neuromuscular Electrical Stimulation And Repeated Peripheral Magnetic Stimulation On Upper Limb Spasm After Stroke

Objective:To investigate whether neuromuscular electrical stimulation(NMES)and repeated peripheral magnetic stimulation(rPMS)can improve flexor spasm of upper limbs of stroke patients under the parameters of this test,and compare the treatment effects of the two.Methods:In this trial,30 stroke patients who met the inclusion and exclusion criteria were randomly divided into a neuromuscular electrical stimulation group,a repeated peripheral magnetic stimulation group,and a blank control group using a random number table method.All three groups received conventional rehabilitation training for stroke,the NMES group received alternating stimulation of the biceps and triceps,the rPMS group received magnetic stimulation of the biceps and triceps,and the blank control group received only conventional rehabilitation training.The modified Tardieu scale(MTS),surface electromyogram(sEMG),and the F wave amplitude and latency of the median nerve of the affected upper limb were measured before and after the treatment ten times.The changes of the above-mentioned related indicators before and after treatment were compared.Results:Compared with before treatment,the rPMS group had significantly improved flexor spasm in the upper limbs after treatment compared with that before treatment,and the MTS score and the integrated electromyographic value(IEMG)of the biceps resting state were significantly reduced(P<0.01).And compared with the control group and the NMES group,the MTS score and IEMG of the biceps brachii were better than those of the other two groups,and the differences were statistically significant(P <0.01).The improvement of the MTS score between the NMES group and the control group was statistically significant(P<0.01),and the improvement of the biceps brachialis IEMG was not statistically significant(P>0.05).There were no statistically significant changes in F-wave latency and amplitude before and after treatment in the three groups.Conclusion :Compared with conventional treatment,rPMS and NMES can significantly improve flexor cramps of upper limbs in patients with stroke,and rPMS is better than NMES.
