The Clinical Study Of Acupuncture At Quchi And Waiguan Acupoints On Upper Limbs Of Hemiplegic After Stroke On The Fluence Of H-reflex And F-wave

Objective: The aim of this study was to investigate the effect of acupuncture at “Quchi(LI11)and Waiguan(SJ5)” acupoints the affected side on H-reflex and F-wave of hemiplegic upper limbs(Brunnstrom stage ?-? and Modified Ashworth stage 1-2)in stroke patients,and to explore its mechanism of hemiplegia in spinal cord loop mechanism.Method: 48 patients who met the inclusion criteria were randomly divided into experimental group and control group,24 cases in each group.The control group received pseudo-acupuncture at “Quchi(LI11)and Waiguan(SJ5)” acupoints,while the experimental group received real acupuncture at “Quchi(LI11)and Waiguan(SJ5)” acupoints for 30 minutes each time.The excitability of motor neurons in the anterior horn of spinal cord was evaluated by Hmax/Mmax and Fmax/Mmax,and the degree of motor function was evaluated by Wolf Motor Function Test(WMFT),the spasticity of patients was assessed by Modified Ashworth Scale(MAS).Result: 1.Compared with the pseudo-acupuncture group,there were significant differences in Hmax/Mmax,Fmax/Mmax and WMFT scores after needle extraction in the acupuncture group(P < 0.05),but there was no significant difference in MAS scores(P > 0.05).2.There were significant differences in Hmax/Mmax,Fmax/Mmax and WMFT scores in the acupuncture group after needle extraction compared with those before needling(P < 0.05),but there was no significant difference in MAS scores(P > 0.05)3.There was no significant difference in Hmax/Mmax,Fmax/Mmax,WMFT,MAS scores between the pseudo-acupuncture group and the pre-acupuncture group(P > 0.05).Conclusion: 1.After needling Quchi and Waiguan acupoints in hemiplegic upper limbs,the improvement of upper limb motor function can be found by Wolf motor function test scale.2.The improvement of upper limb function in patients with hemiplegia after needling Quchi and Waiguan acupoints is not directly related to the decrease of modified Ashworth.3.The improvement of upper extremity function by acupuncture at Quchi and Waiguan acupoints on the affected side may be partly due to the regulation of spinal cord circuitry,which is manifested by the decrease of Hmax/Mmax and Fmax/Mmax.
