The activity of the trapezius muscle is reportedly higher than that of other neck accessory muscles under a condition of increased inspiratory pressure in the standing position. The present study aimed to compare the activity of the trapezius muscle with those of the scalene and sternocleidomastoid muscles under a condition of increased inspiratory pressure in the supine position. This study included 40 subjects, and the muscle activity was measured using surface electromyography. Regarding the results, there was a significant difference in the muscle activity between the trapezius muscle and the scalene and sternocleidomastoid muscles (p = 0.003) in both men and women. Post-hoc analysis showed significant differences between trapezius and the other muscles. Moreover, there was no difference between the scalene and sternocleidomastoid muscles (p = 0.596). The increase in the change in electromyography activity of the muscle is greater in the trapezius muscle than in other muscles when the level of inspiratory pressure increases in the supine position.
在站立位增加吸气压力的情况下，斜方肌的活动据称高于其他颈部辅助肌肉。本研究旨在比较仰卧位增加吸气压力时斜方肌与颈长肌和胸锁乳突肌的活动。本研究包括 40 名受试者，使用表面肌电图测量肌肉活动。结果显示，男性和女性斜方肌与颈长肌和胸锁乳突肌之间的肌肉活动存在显著差异（p=0.003）。事后分析显示，斜方肌与其他肌肉之间存在显著差异。此外，颈长肌和胸锁乳突肌之间没有差异（p=0.596）。当仰卧位吸气压力增加时，斜方肌的肌电图活动变化增加幅度大于其他肌肉。
