Abstract

Objective

The aim of the present study was to assess the immediate effects of a single session of cervical spine manipulation on cervical movement patterns, disability, and the patient's perceived improvement in people with nonspecific neck pain.

Methods

A single-blinded, randomized, sham-controlled trial was carried out at a biomechanics institute. Fifty participants diagnosed with acute and chronic nonspecific neck pain (minimum duration of the symptoms being 1 month) were randomized to an experimental group (EG, n = 25) or a sham-control group (CG, n = 25, 23 of whom completed the study). EG received a single cervical spine manipulation session; CG received a single placebo intervention. Both groups received manipulation or sham from the same physiotherapist. Main outcome measures were neck kinematics (ie, range of motion and movement harmony) during cyclic movements, self-reported neck disability, and impression of change assessed before and 5 minutes after treatment.

Results

The EG showed no significant improvements (P > .05) in any of the studied biomechanical variables, except for right-side bending and left rotation, in which we found a range of motion significant mean difference of 1.97° and 1.95°, respectively (P < .05). The CG showed enhanced harmonic motion during flexion (P < .05). Both groups showed a significant decrease in self-reported neck disability after treatment (P < .05), and EG participants perceived a significantly larger improvement after manipulation compared with the CG (P < .05).

Conclusions

A single session of cervical manipulation provided by a physiotherapist had no impact on cervical motion during cyclic movements, but rather induced self-reported perceived improvement in neck disability and impression of change after treatment in people with nonspecific neck pain.

单次颈椎推拿对非特异性颈痛患者颈椎运动模式的直接影响:一项随机对照试验
目的:本研究的目的是评估单次颈椎推拿对非特异性颈痛患者颈椎运动模式、残疾和患者感知改善的直接影响。方法在某生物力学研究所进行单盲、随机、假对照试验。50名被诊断为急性和慢性非特异性颈部疼痛的参与者(症状持续时间最短为1个月)被随机分为实验组(n = 25)或假对照组(CG, n = 25,其中23人完成了研究)。EG接受单次颈椎推拿;CG接受单一安慰剂干预。两组均接受同一理疗师的手法治疗或假治疗。主要结果测量是循环运动期间的颈部运动学(即运动范围和运动和谐),自我报告的颈部残疾,以及治疗前和治疗后5分钟评估的变化印象。结果EG无明显改善(P >.05)在任何研究的生物力学变量中,除了右侧弯曲和左侧旋转,我们发现运动范围的平均差异分别为1.97°和1.95°(P <. 05)。CG在屈曲过程中谐波运动增强(P <. 05)。两组患者治疗后自我报告的颈部残疾均显著减少(P <.05),与CG相比,EG参与者在操作后感知到更大的改善(P <. 05)。结论物理治疗师提供的单次颈椎推拿对循环运动中的颈椎运动没有影响,但会诱导非特异性颈部疼痛患者自我报告的颈部残疾改善和治疗后的改变印象。
