研究设计.横截面研究。本研究比较了10例慢性颈痛患者和10例对照组在颅颈屈曲试验中深、浅颈屈肌的活动和颅颈屈曲运动范围。患有慢性颈痛的个体在颅颈屈曲测试中表现出降低的表现，并且这种动作的训练在颈部投诉的管理中是有效的。虽然该测试被假设为反映颈深屈肌的功能障碍，但尚未进行测试。深颈屈肌肌电图活动记录与自定义电极插入通过鼻子和固定的后粘膜的口咽部的吸力。将表面电极放置在颈浅肌（胸锁乳突肌和前斜角肌）上。测量仰卧位时5个递增水平的颅颈屈曲肌电均方根振幅和颅颈屈曲活动范围。颈深屈肌的肌电振幅与对照组和颈痛组的颅颈屈试验的递增阶段之间存在较强的线性关系（P = 0.002）。颈痛组颈深屈肌肌电活动幅度低于对照组，且在高增量任务中差异有统计学意义（P < 0.05）。颈痛组的胸锁乳突肌和前斜角肌肌电活动有明显增加的趋势，但不显著。这些数据证实，降低性能的颅颈屈试验与功能障碍的颈深屈肌，并支持该测试的有效性，颈部疼痛的患者。
Study Design. Cross-sectional study.Objective. The present study compared activity of deep and superficial cervical flexor muscles and craniocervical flexion range of motion during a test of craniocervical flexion between 10 patients with chronic neck pain and 10 controls.Summary of Background Data. Individuals with chronic neck pain exhibit reduced performance on a test of craniocervical flexion, and training of this maneuver is effective in management of neck complaints. Although this test is hypothesized to reflect dysfunction of the deep cervical flexor muscles, this has not been tested.Methods. Deep cervical flexor electromyographic activity was recorded with custom electrodes inserted via the nose and fixed by suction to the posterior mucosa of the oropharynx. Surface electrodes were placed over the superficial neck muscles ( sternocleidomastoid and anterior scalene). Root mean square electromyographic amplitude and craniocervical flexion range of motion was measured during five incremental levels of craniocervical flexion in supine.Results. There was a strong linear relation between the electromyographic amplitude of the deep cervical flexor muscles and the incremental stages of the craniocervical flexion test for control and individuals with neck pain ( P = 0.002). However, the amplitude of deep cervical flexor electromyographic activity was less for the group with neck pain than controls, and this difference was significant for the higher increments of the task ( P < 0.05). Although not significant, there was a strong trend for greater sternocleidomastoid and anterior scalene electromyographic activity for the group with neck pain.Conclusions. These data confirm that reduced performance of the craniocervical flexion test is associated with dysfunction of the deep cervical flexor muscles and support the validity of this test for patients with neck pain.
