Abstract

The purpose of this study was to analyze the effects of computer game usage time on trunk muscle thickness and pressure pain threshold. The 33 study participants were divided into Group A, which spent less than 10 hours per week playing computer games; Group B, which spent between 10 and 20 hours per week playing computer games; and Group C, which spent more than 20 hours per a week playing computer games. The thickness of the participants' upper trapezius (UT), pectoralis minor (PM), anterior scalene (AS), and middle scalene (MS) muscles as well as the pressure pain threshold of their UT, PM, AS, MS, and levator scapular (LS) were measured. The study found that the PM, AS, and MS muscle thickness in group C was significantly greater than in the other groups (p<.05), and the UT, AS, PM, and LS pressure pain threshold in group C was significantly lower than in other groups (p<.05). Therefore, those who use computers for a long period of time during the week should recognize that their computer usage may cause musculoskeletal disorders.

본 연구는 일주일 동안의 컴퓨터 사용시간이 몸통 근육 두께와 압력 통증 역치에 미치는 영향을 분석하였다. 33명의 대상자를 일주일에 컴퓨터를 10시간 이하(A 그룹), 10시간에서 20시간(B 그룹), 20시간 이상 사용하는 그룹(C 그룹)으로 나누어 위 등세모근, 작은가슴근, 앞 목갈비근, 중간 목갈비근의 근 두께와 위 등세모근, 작은가슴근, 앞 목갈비근, 중간 목갈비근, 어깨올림근의 압력 통증 역치를 측정하였다. 본 연구의 결과 C 그룹의 작은가슴근, 앞 목갈비근, 중간 목갈비근은 다른 그룹들의 근 두께에 비해 유의하게 증가되었고(p<.05) 위 등세모근, 앞 목갈비근, 작은가슴근, 어깨올림근의 압력통증역치는 다른 그룹들에 비해 유의하게 감소하였다(p<.05). 그러므로, 본 연구는 1주일 동안 컴퓨터를 장시간 사용하는 사람들은 장시간 컴퓨터 사용이 다양한 근골격계 질환의 원인이 될 수 있음을 인지하고 그에 따른 적절한 예방적 접근을 수행할 것을 권장한다.
