Effect of tight clothes on cervical and thoracic spine muscles during shoulder abduction.
[Purpose] The purpose of this study was investigated the effect of tight clothes on cervical and thoracic spine muscles activities during shoulder abduction. [Subjects and Methods] The subjects of this study were 10 healthy males. The subjects performed two shoulder abduction trials for each of two jacket-wearing conditions. The right upper, middle, and lower trapezius and serratus anterior muscles activities were measured using a surface electromyography system during right shoulder abduction. [Results] The upper and middle trapezius muscle activities during shoulder abduction were significantly increased under the tight-jacket conditions compared with the general-jacket conditions. The lower trapezius and serratus anterior muscle activities were significantly decreased under the tight-jacket conditions compared with the general-jacket conditions. [Conclusion] The results of this study suggest that normal scapular movements did not occur sufficiently when wearing a tight jacket.
