Background

The purpose of this study was to evaluate the effect of low-frequency self-administered vibration therapy into myofascial trigger points in the upper trapezius and levator scapulae on patients with chronic non-specific neck pain.

Methods

Twenty-eight patients with chronic non-specific neck pain were randomly assigned into a vibration group, receiving 10 self-applied sessions of vibration therapy in the upper trapezius and levator scapulae trigger points; or a control group, receiving no intervention. Self-reported neck pain and disability (Neck Disability Index) and pressure pain threshold were assessed at baseline and after the first, fifth and 10th treatment sessions.

Findings

Significant differences were found in the vibration group when compared to the control group after the treatment period: the vibration group reached lower Neck Disability Index scores (F = 4.74, P = .033, η² = 0.07) and greater pressure pain threshold values (F = 7.56, P = .01, η² = 0.10) than the control group. The vibration group reported a significant reduction in Neck Disability Index scores (χ2 = 19,35, P = .00, Kendall's W = 0.28) and an increase in pressure pain threshold (χ2 = 87,10, P = .00, Kendall's W = 0.73) between the assessment times over the course of the treatment. The mean increase in pressure pain threshold in the vibration group after the 10 sessions was 8.54 N/cm2, while the mean reduction in Neck Disability Index scores was 4.53 points.

Interpretation

Vibration therapy may be an effective intervention for reducing self-reported neck pain and disability and pressure pain sensitivity in patients with chronic non-specific neck pain. This tool could be recommended for people with non-specific neck pain.

振动疗法对颈部肌筋膜触发点的影响：一项随机对照试验研究。

背景

这项研究的目的是评估低频自我管理振动疗法对斜方肌和肩提肌肌筋膜触发点对慢性非特异性颈痛患者的影响。

方法

将28例慢性非特异性颈痛患者随机分为一个振动组，在斜方肌上提肌和肩trigger骨肩trigger肌触发点接受10次自我应用的振动疗法。或对照组，没有任何干预。在基线以及第一次，第五次和第十次治疗之后评估自我报告的颈部疼痛和残疾（颈部残疾指数）和压力疼痛阈值。

发现

显著差异振动组中发现相比于在治疗期后的对照组时：振动组达到下颈部残疾指数评分（F = 4.74，P  = 0.033，η ²  = 0.07）和更大的压力疼痛阈值（ F = 7.56，P  = 0.01，η ²  = 0.10）低于对照组。振动组报告颈部残疾指数得分显着降低（χ2= 19,35，P  = .00，肯德尔W = 0.28）和压力痛阈值增加（χ2= 87,10，P 在整个治疗过程中的评估时间之间= .00，肯德尔W = 0.73）。在10个疗程后，振动组的压力疼痛阈值平均增加了8.54 N / cm2，而颈部残疾指数得分的平均减少了4.53点。

解释

振动疗法可能是一种有效的干预措施，可减轻慢性非特异性颈部疼痛患者的自我报告的颈部疼痛，残疾和压力疼痛敏感性。可以将这种工具推荐给非特定性颈部疼痛的人。
