초록

본 연구의 목적은 앉은 자세에서 골반의 앞방향경사와 뒷방향경사에 따른 스마트폰의 사용이 목세움근과 위등세모근의 근활성도를 알아보고 IoT 디바이스 개발에 필요한 기초자료를 얻고자 하였다. 건강한 20-30대 성인남녀 15명을 대상으로 앉은 자세에서 골반앞방향경사와 골반뒷방향경사를 중재한 뒤 5분간 스마트폰을 사용하여 근전도 신호를 측정하고 중앙 3분의 근전도 신호를 사용하였다. 연구결과 앉은 자세에서 골반앞방향경사의 스마트폰 사용이 골반뒤방향경사와 비교하여 양측 목세움근(p<.001), 왼쪽 위등세모근(p<.001), 오른쪽 위등세모근(p<.002)의 %RVC 값이 유의하게 낮았다. 이는 골반의 앞방향경사를 통한 앉은 자세가 척추의 정상적인 만곡을 유지하여 스마트폰 사용 시 발생하게 되는 전방머리자세를 방지하여 목과 어깨 주변의 부하를 감소시켜 %RVC 값이 유의하게 낮았다고 사료되며 향후 골반경사에 중점을 둔 새로운 자세교정 IoT 디바이스들이 개발되어야할 것이다.

The purpose of this study was to investigate muscle activity of cervical erector spinae & upper trapezius while using a smartphone according to anterior pelvic tilt & posterior pelvic tilt in sitting position. & we also want to obtain basic data necessary for development of IoT devices. Fifteen healthy men & women aged 20-30 were enolled, After anterior pelvic tilt & posterior pelvic tilt in sitting position were adjusted, they used a smartphone for 5 minutes & EMG signal was measured simultaneously. We used median 3 minutes of measured EMG signal. The results of this study were as follows: In the sitting position, the use of smartphone in anterior pelvic tilt had significantly lower %RVC values in both cervical erector spinae (p <.001), left upper trapezius (p <.001) & right upper trapezius (p <.002) in comparison with posterior pelvic tilt. This means that anterior pelvic tilt make vertebrae maintain normal curvature & prevent forward head posture occurred while using a smartphone. It reduces loads around neck & shoulders, so that %RVC value is significantly lowered. In the future, new posture corrected IoT devices with an aspect of pelvic tilt should be developed.
