초록

Purpose The usage of a smartphone in the life have been increased because of the convenience of a smartphone. In addition, the usage of a smartphone is increased in the restroom. The use of smartphone in the toilets have affected on large intestine such as constipation and hemorrhoids. However, little is known about musculoskeletal system. Therefore, the Purpose of this study was to examine the effect of using smarphone in the restroom on muscle activity of cervical erector spineae, upper trapezius, and lumbar erector spinae in the able bodied people. Methods 28 healthy subjects were recruited for this study. Electromyographic signals of both cervical erector spinae, upper trapezius and lumbar erector spinae were acquired during sitting on the general chair and toilet with using a smartphone. Paired t test was used for determination of differences in the muscle activation between general chair and toilet. The significant level of the p value was set at 0.05. Results In cervical erector spinae and upper trapezius, no significant difference was observed between the general chair and toilet (p>.05). In contrast, regarding lumbar erector spinae, using a smartphone on the toilet showed significant difference compared to on the general chair (p<.05). Conclusion We found that the sitting on the toilet during using a smartphone showed higher muscle activation of lumbar erector spinae than the sitting on the general chair. Therefore, using a smartphone on the toilet could affect the musculoskeletal of the lower back.
