Purpose: This study aimed to prove that surface electromyography(SEMG) can be used to identify the degree of symptoms of diseases in the upper extremities; it also aimed to confirm various potential therapeutic effects through an inquiry into the value measured by the SEMG on certain acupuncture points in the upper extremities.
Methods: Fifty healthy people received instructions for the method of exercise: wrist flexion, extension and hand grasping. Disposable electrodes were attached to acupuncture points of Susamni(LI10), Naegwan(PC6), Oegwan(TE5) and below Sohae(HT3) two cun on both sides in flexion, extension and grasping to measure the SEMG values. The research results were analyzed using SPSS statistics Ver. 22.0(IBM, USA).
Results: The average value was highest on Naegwan(PC6) in grasping, and the average SEMG value was higher in the order of grasping, extension and flexion. The asymmetry index of each point was Susamni(LI10) 16.26±13.59 %, Oegwan(TE5) 20.38±15.59 %, below Sohae(HT3) two cun 20.89±16.77 %, Naegwan(PC6) 22.49±14.91 % in wrist extension, Susamni(LI10) 25.99±21.44 %, Oegwan(TE5) 21.15±15.94 %, below Sohae(HT3) two cun 19.62±15.46 %, Naegwan(PC6) 19.93±16.85 % in wrist flexion, Susamni(LI10) 16.60±12.21 %, Oegwan(TE5) 10.94±8.29 %, below Sohae(HT3) two cun 15.20±12.60 %, Naegwan(PC6) 11.68±7.77 % in grasping.
Conclusions: In this study, to identify the degree of symptoms of diseases in the upper extremities and confirm therapeutic effects, it is necessary to analyze the calculated percentage and compare the SEMG measurement of special points with those of other points, and with the asymmetry index.
