目的：本研究的目的是调查与手动高速度，低振幅（HVLA）脊柱操作系统地应用于上，下颈椎和上胸椎在队列轻度neck disability.Methods：这项研究是一个描述性的观察性调查，与所有参与者接受相同的干预措施相关的肌电图反应的程度。19名轻度颈部残疾的参与者接受了6次颈椎和上胸椎手动HVLA操作。双极表面肌电图电极对被用来测量16个颈部，背部和四肢出口肌肉双边的反应。结果：与颈部和胸部操作相关的肌电图反应发生在中位数的16个（范围：1-14）记录的肌肉4。颈椎手法与颈部肌肉的肌电反应率最高相关，而上胸椎手法后背部肌肉的反应率最高。颈椎手法与颈椎肌肉肌电图反应率最高相关（胸锁乳突肌和颈夹肌），而背部肌肉的反应上胸椎手法组（上、中背阔肌、背阔肌和胸最长肌）的肌电活动最高。这一结果表明，与脊柱操作相关的肌电图肌肉反应主要发生在局部（靠近目标节段），而不是远端。（J Manipulative Physiol Ther 2022;45;33-44）
Objectives: The purpose of this study was to investigate the extent of electromyographic responses associated with manual high-velocity, low-amplitude (HVLA) spinal manipulation systematically applied to the upper and lower cervical and upper thoracic spines in a cohort with mild neck disability.Methods: The study was a descriptive observational investigation, with all participants receiving the same interventions. Nineteen participants with mild neck disability received 6 manual HVLA manipulations to the cervical and upper thoracic spine. Bipolar surface electromyography electrode pairs were used to measure responses of 16 neck, back, and limb outlet muscles bilaterally. The number of electromyographic responses was then calculated.Results: Electromyographic responses associated with cervical and thoracic manipulation occurred in a median of 4 of the 16 (range: 1-14) recorded muscles. Cervical spinal manipulation was associated with the highest rates of electromyographic responses in neck muscles, whereas responses in back muscles were highest after upper thoracic manipulation.Conclusion: Cervical spinal manipulation was associated with the highest rate of electromyographic responses in muscles of the cervical spine (sternocleidomastoid and splenius cervicis), whereas responses in back muscles (upper and middle trapezius, latissimus dorsi, and longissimus thoracis) were highest after upper thoracic manipulations. This result suggests that electromyographic muscular responses associated with spinal manipulation primarily occur locally (close to the target segment) rather than distally.
