颈脊柱推拿对减轻慢性颈痛患者肘屈肌抑制机制研究

A research about decreasing hi elbow flexor inhibition after cervical spine manipulation in patients with chronic neck pain

目的:通过对16例慢性颈痛患者进行研究,测量颈痛患者行颈脊柱推拿前后功能量和主观疼痛改变情况。方法:颈脊柱推拿选定C5-7水平,用插入颤搐方法和肌电描记法评定肘屈肌在最大范围内随意收缩时二头肌激活作用。颈活动度和压痛阈用关节角度计和痛觉计进行测量。结果:治疗前,患者表现典型的二头肌抑制,颈部活动侧面受限,压痛敏感性增高。颈脊柱推拿后,二头肌抑制明显下降并伴随二头肌肌力增强,颈部活动度和压痛阈显著提高。结论:脊柱推拿术可以提高肌肉功能、颈部活动度和疼痛敏感性。

AIM: This study measured functional capacity and subjective pain in 16 patients with chronic neck pain before and after manipulation of the cervical spine. METHODS: Manipulation of the cervical spine was applied at the level of C5-7, Biceps activation during a maximal voluntary elbow flexor contraction was assessed using the interpolated twitch technique and elec-tromyography. Cervical range of motion and pressure pain thresholds were measured using a goniometer and an algometer. RESULTS: Patients showed significant inhibition in their biceps muscles. Cervical range of motion was restricted laterally, and increased pressure pain sensitivity was evident After cervical spine manipulation, a significant reduction in biceps inhibition and an increase in biceps force occurred. Cervical range of motion and pressure pain thresholds increased significantly. CONCLUSION: Spinal manipulation can improve muscle function, cervical range of motion and pain sensitivity.
