Abstract

The purpose of this study was to investigate the optimal position among three manual muscle tested positions for upper trapezius in which to obtain an isolated upper trapezius EMG signal for the normalization of upper trapezius muscle EMG activity. A total of 28 healthy adult men participated in the experiment. The UT (upper trapezius) and LS (levator scapulae) muscle activities were measured using the TeleMyo 2400T and analyzed using MyoResearch software. The muscle activity of the US and LS was measured by performing three manual muscle test positions for the upper trapezius. The UT/LS ratio during the S-MVIC was 80.25 and was significantly higher than that during the T-MVIC (76.50; p = 0.011) and the C-MVIC (60.95; p < 0.001). And, the UT/LS ratio during the T-MVIC and was significantly higher than that during the C-MVIC (p < 0.001). Based on the results of present study, we suggest a switch from T-MVIC to S-MVIC for the independent normalization reliability of upper trapezius EMG activity. The UT muscle strength or normalization test using S-MVIC will be able to measure muscle strength or activity of UT compared to previous measurement methods.

본 연구의 목적은 상부 승모근 근활성도에 대한 정규화를 하는 동안, 어떠한 도수 근력 검사 자세가 상부 승모근의 선택적 활성화에 최적화된 자세인지를 알아보고자 하였다. 28명의 성인 남.녀가 본 연구에 참여하였다. 상부 승모근과 견갑거근의 근활성도를 측정하기 위해 근전도를 이용하였다. 세 가지 도수근력 검사 자세에서 견갑거근에 대한 상부 승모근의 활성비를 측정하였다. 다른 측정 자세와 비교하여 S-MVIC 자세에서 유의하게 높은 상부 승모근/견갑거근 근활성비(S-MVIC: 80.25, T-MVIC: 76.50, C-MVIC: 60.95)를 보였다. 그리고 C-MVIC와 비교하여 T-MVIC가 유의하게 높은 상부 승모근/견갑거근 근활성비를 보였다. 실험 결과를 토대로 기존의 T-MVIC 검사 자세에서 S-MVIC로 상부 승모근 근전도 정규화 검사 자세를 바꾸는 것이 상부 승모근의 선택적 근활성도 수집의 정규화 신뢰도를 높이는데 도움이 될 것이다. 이전 측정방법과 비교하여 S-MVIC를 이용한 상부 승모근 근력 또는 근활성도 측정방법은 상부 승모근의 근력 또는 근활성도의 독립적 측정이 가능하다.
