Effect and Electrophysiological Characteristics of Acupuncture Combined with RFE in Treatment of Upper Limb Dysfunction after Stroke
Objective To observe the effect of acupuncture combined with repetitive facilitative exercise(RFE)on upper limb dysfunction after stroke and its influence on electrophysiological characteristics.Method A total of 135 patients with upper limb dysfunction after stroke admitted to the Department of Encephalopathy from January 2022 to December 2022 were selected as re-search objects and divided into acupuncture group,RFE group and combined group by random number table method,with 45 ca-ses in each group.All groups were given the conventional drug therapy and rehabilitation training.Besides,the acupuncture group was given the acupuncture therapy on the basis of the conventional treatment,the RFE group was given RFE method on the basis of the conventional treatment,and the combined group was given acupuncture combined with RFE method on the basis of the conventional treatment,once a day,5 consecutive days a week with 2 days off,for a total of 8 weeks.Before and after 4 and 8 weeks of treatment,the upper limb motor function(Fugl-Meyer Assessment,FMA),upper limb muscle tone(Modified Ashworth Scale,MAS),hand motor function(Wolf motor function test,WMFT)and ability of perform activities of daily living(MBI)were compared between the three groups.The maximum contractile electromyography(EMG)limit values of biceps,triceps and exten-sor wrist dorsum were compared among the three groups and measured by biofeedback therapy instrument.Result After 4 and 8 weeks of treatment,the simplified FMA score,WMFT score and MBI score were significantly different among the three groups by overall comparison(P＜0.05),and they were significantly improved after treatment compared with those before treatment(P＜0.05),while the scores of the combined group were significantly higher than those of the acupuncture group and RFE group(P＜0.05).The modified MAS scores of the three groups were also significantly different by overall comparison(P＜0.05),and they were significantly lower after treatment than those before treatment(P＜0.05),while the scores of the combined group were sig-nificantly lower than those of the acupuncture group and RFE group(P＜0.05).After 4 and 8 weeks of treatment,there were sig-nificant differences in the EMG limits for maximum contractions of biceps,triceps and extensor carpi dorsi among the three groups by overall comparison(P＜0.05),and the above EMG limits of the three groups were significantly higher than those before treat-ment(P＜0.05),while the EMG limits of the combined group were significantly higher than those of the acupuncture group and RFE group(P＜0.05).Conclusion Acupuncture combined with RFE in the treatment of upper limbs dysfunction after stroke can effectively improve the EMG limit value during maximum contraction of the main muscle groups of the upper limbs and hands,im-prove the contraction ability of the muscles of the upper limbs and hands,and thus significantly improve the movement function of the upper limbs and hands,reduce the muscle tension of the upper limbs,and improve the ability of the activities of daily living of the patients.
