The purpose of this study was to assess the effects of a low-load training program for the deep cervical flexors (DCFs) on pain, disability, and pressure pain threshold (PPT) over cervical myofascial trigger points (MTrPs) in patients with chronic neck pain.
Thirty patients with chronic idiopathic neck pain participated in a 6-week program of specific training for the DCF, which consisted of active craniocervical flexion performed twice per day (10-20 minutes) for the duration of the trial. Perceived pain and disability (Neck Disability Index, 0-50) and PPT over MTrPs of the upper trapezius, levator scapulae, and splenius capitis muscles were measured at the beginning and end of the training period.
After completion of training, there was a significant reduction in Neck Disability Index values (before, 18.2 ± 12.1; after, 13.5 ± 10.6; P < .01). However, no significant changes in PPT were observed over the MTrPs.
Patients performing DCF training for 6 weeks demonstrated reductions in pain and disability but did not show changes in pressure pain sensitivity over MTrPs in the splenius capitis, levator scapulae, or upper trapezius muscles.
本研究旨在评估一项针对颈深屈肌（DCF）的低负荷训练计划对慢性颈部疼痛患者颈部肌筋膜触发点（MTrP）处的疼痛、功能障碍及压痛阈值（PPT）的影响。
30例慢性特发性颈部疼痛患者参加了为期6周的DCF专项训练计划，该计划包括在试验期间每天进行两次主动颅颈屈曲训练（每次10 - 20分钟）。在训练期开始和结束时测量患者的疼痛感知、功能障碍（颈部功能障碍指数，0 - 50）以及上斜方肌、肩胛提肌和头夹肌MTrP处的PPT。
训练结束后，颈部功能障碍指数值显著降低（训练前，18.2±12.1；训练后，13.5±10.6；P <.01）。然而，MTrP处的PPT未观察到显著变化。
进行6周DCF训练的患者疼痛和功能障碍减轻，但头夹肌、肩胛提肌或上斜方肌MTrP处的压痛敏感性未发生变化。
