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.
