姿势矫正是治疗慢性颈肩痛的有效康复技术，旨在通过采取中立姿势来减轻周围肌肉的负荷。本研究的目的是评估实时高密度表面肌电图 (HDsEMG) 生物反馈对于打字期间姿势矫正的有效性。 20 名健康参与者通过两种形式的姿势反馈执行打字任务：(1) 口头姿势指导和 (2) 口头姿势指导加上 HDsEMG 生物反馈。该界面使用放置在斜方肌上的两个 HDsEMG 阵列的活动，旨在将斜方肌活动向下移动。两个阵列的重心用于量化斜方肌活动的空间分布。从上肢反射标记获取的平面角度量化了颈肩胛姿势。在生物反馈条件下，与单独的口头姿势训练相比，斜方肌活动位置下移了 12.74 ± 3.73 mm，肩胛骨内收多了 2.58 ± 1.18°，凹陷多了 0.23 ± 0.24°。结果表明，实时 HDsEMG 生物反馈干预在实现姿势矫正方面具有短期有效性，并且与单独的口头姿势指导相比，可能更有效地产生斜方肌活动的劣势转变。
Postural correction is an effective rehabilitation technique used to treat chronic neck and shoulder pain, and is aimed toward reducing the load on the surrounding muscles by adopting a neutral posture. The objective of this investigation was to evaluate the effectiveness of real-time high-density surface EMG (HDsEMG) biofeedback for postural correction during typing. Twenty healthy participants performed a typing task with two forms of postural feedback: (1) verbal postural coaching and (2) verbal postural coaching plus HDsEMG biofeedback. The interface used activity from two HDsEMG arrays placed over the trapezius designed to shift trapezius muscle activity inferiorly. The center of gravity across both arrays was used to quantify the spatial distribution of trapezius activity. Planar angles taken from upper extremity reflective markers quantified cervicoscapular posture. During the biofeedback condition, trapezius muscle activity was located 12.74 ± 3.73 mm more inferior, the scapula was 2.58 ± 1.18° more adducted and 0.23 ± 0.24° more depressed in comparison to verbal postural coaching alone. The results demonstrate the short-term effectiveness of a real-time HDsEMG biofeedback intervention to achieve postural correction, and may be more effective at creating an inferior shift in trapezius muscle activity in comparison to verbal postural coaching alone.
