Knowledge on the spinal kinematics and muscle activation of the cervical and thoracic spine during functional task would add to our understanding of the performance and interplay of these spinal regions during dynamic condition. The purpose of this study was to examine the influence of chronic neck pain on the three-dimensional kinematics and muscle recruitment pattern of the cervical and thoracic spine during an overhead reaching task involving a light weight transfer by the upper limb. Synchronized measurements of the three-dimensional spinal kinematics and electromyographic activities of cervical and thoracic spine were acquired in thirty individuals with chronic neck pain and thirty age- and gender-matched asymptomatic controls. Neck pain group showed a significantly decreased cervical velocity and acceleration while performing the task. They also displayed with a predominantly prolonged coactivation of cervical and thoracic muscles throughout the task cycle. The current findings highlighted the importance to examine differential kinematic variables of the spine which are associated with changes in the muscle recruitment in people with chronic neck pain. The results also provide an insight to the appropriate clinical intervention to promote the recovery of the functional disability commonly reported in patients with neck pain disorders.
在进行功能任务时，了解颈椎和胸椎的脊柱运动学和肌肉激活情况，可以帮助我们更好地理解这些脊柱区域在动态条件下的表现和相互作用。本研究的目的是探讨慢性颈痛对上肢进行轻负荷转移的过顶伸展任务中颈椎和胸椎三维运动学和肌肉募集模式的影响。通过同步测量 30 名慢性颈痛患者和 30 名年龄和性别匹配的无症状对照者的三维脊柱运动学和颈胸段脊柱肌电活动。在执行任务时，颈痛组的颈椎速度和加速度明显降低。他们还表现出颈椎和胸椎肌肉在整个任务周期中主要是延长的共同激活。目前的研究结果强调了检查与慢性颈痛患者肌肉募集变化相关的脊柱运动学差异变量的重要性。研究结果还为促进颈痛患者常见的功能障碍恢复的适当临床干预提供了深入了解。
