Abstract：Objective To explore the effects of intermediate frequency modulation electrical stimulation combined with conventional rehabilitation on functional recovery of bilateral active trunk flexor muscles and bilateral synergistic trunk flexor muscles in patients with hemiplegic stroke.Methods Forty hemiplegic stroke patients were treated with conventional rehabilitation(control group,n=20) or in combination with intermediate frequency modulation electrical stimulation(treatment group,n=20) for 40 days.Surface electromyogram(sEMG) was recorded to measure the maximum(MAX) and root mean square(RMS) values and bilateral active trunk flexor muscle,bilateral synergistic trunk flexor muscle MAX,RMS and the ratio of bilateral active trunk flexor muscle MAX to bilateral synergistic trunk flexor muscle MAX.Activities of daily living(ADL) were assessed by using Fugl-Meyer Balance Function Assessment Scale and Barthel Index.Results After treatment,the surface electromyography MAX and RMS vales were significantly changed(P<0.05).Furthermore,the MAX and RMS values and the ratio of bilateral active trunk flexor muscle MAX to bilateral synergistic trunk flexor muscle MAX in treatment group were obviously different from those in control group(all P<0.05).In control group,Barthel ADL index score was not significantly changed after treatment(P>0.05).However,there were obvious differences in ADL ability and Barthel ADL index score between control group and treatment group(P<0.05).Conclusion Intermediate frequency modulation electrical stimulation combined with conventional rehabilitation can improve motor function,balance capacity and ADL ability of bilateral active trunk flexor muscles and bilateral synergistic trunk flexor muscles in patients with hemiplegic stroke.
