背景和目的不良的坐姿与颈部疼痛症状的发生和持续存在有关。本研究有 2 个目的：(1) 比较慢性颈部疼痛受试者和对照受试者在分心任务期间颈椎和胸部姿势的变化，以及 (2) 比较 2 种不同颈部锻炼方案对颈部疼痛患者在这项任务期间保持直立颈椎和胸部姿势的能力的影响。受试者 58 名患有慢性、非严重颈部疼痛的受试者和 10 名对照受试者参与了这项研究。在 10 分钟的计算机任务中，每 2 分钟测量一次直立姿势。基线测量后，患有颈部疼痛的受试者被随机分为两个为期 6 周的运动干预组之一：一组接受颅颈屈肌训练，另一组接受颈屈肌耐力训练。干预后的主要结果是计算机任务期间颈椎和胸部姿势角度的变化。结果颈部疼痛的受试者在任务持续时间内表现出颈椎角度的变化（平均值 = 4.4 度；95% 置信区间 [CI] = 3.3-5.4），与更前倾的头部姿势一致。对照组受试者在任务持续时间内颈椎角度的变化没有观察到显着差异（平均值 = 2.2 度；95% CI = 1.0-3.4）。干预后，颅颈屈肌训练组在计算机任务期间表现出颈椎角度的变化显着减少。讨论和结论这项研究表明，患有慢性颈部疼痛的人在分心时保持直立姿势的能力下降。在进行旨在训练颅颈屈肌的锻炼计划后，患有颈部疼痛的受试者在长时间坐着时保持中立颈椎姿势的能力有所提高。
Background and PurposePoor sitting posture has been implicated in the development and perpetuation of neck pain symptoms. This study had 2 purposes: (1) to compare change in cervical and thoracic posture during a distracting task between subjects with chronic neck pain and control subjects and (2) to compare the effects of 2 different neck exercise regimens on the ability of people with neck pain to maintain an upright cervical and thoracic posture during this task.SubjectsFifty-eight subjects with chronic, nonsevere neck pain and 10 control subjects participated in the study.MethodChange in cervical and thoracic posture from an upright posture was measured every 2 minutes during a 10-minute computer task. Following baseline measurements, the subjects with neck pain were randomized into one of two 6-week exercise intervention groups: a group that received training of the craniocervical flexor muscles or a group that received endurance-strength training of the cervical flexor muscles. The primary outcomes following intervention were changes in the angle of cervical and thoracic posture during the computer task.ResultsSubjects with neck pain demonstrated a change in cervical angle across the duration of the task (mean=4.4 degrees; 95% confidence interval [CI]=3.3-5.4), consistent with a more forward head posture. No significant difference was observed for the change in cervical angle across the duration of the task for the control group subjects (mean=2.2 degrees; 95% CI=1.0-3.4). Following intervention, the craniocervical flexor training group demonstrated a significant reduction in the change of cervical angle across the duration of the computer task.Discussion and ConclusionThis study showed that people with chronic neck pain demonstrate a reduced ability to maintain an upright posture when distracted. Following intervention with an exercise program targeted at training the craniocervical flexor muscles, subjects with neck pain demonstrated an improved ability to maintain a neutral cervical posture during prolonged sitting.
