[Purpose] This study investigated the effect of sleep posture on neck muscle activity. [Subjects and Methods] The study recruited 20 healthy subjects, who were positioned in three supine sleeping positions: both hands at sides, both hands on the chest, and dominant hand on the forehead. The activities of the scalene and upper trapezius muscles bilaterally were measured by surface electromyography. [Results] The upper trapezius and scalene muscle activity on the right side was significantly greater in the supine with dominant hand on the forehead position than in the other positions. [Conclusion] Sleep posture is important and prevent neck and shoulder musculoskeletal pain.
[目的] 本研究调查睡眠姿势对颈部肌肉活动的影响。[对象与方法] 该研究招募了20名健康受试者,让他们处于三种仰卧睡眠姿势:双手放在身体两侧、双手放在胸前、优势手放在前额。通过表面肌电图测量双侧斜角肌和上斜方肌的活动。[结果] 优势手放在前额的仰卧位时,右侧上斜方肌和斜角肌的活动明显大于其他姿势。[结论] 睡眠姿势很重要,可预防颈部和肩部肌肉骨骼疼痛。
