摘要/Abstract

摘要： 目的通过采用本体感觉神经肌肉刺激技术（PNF）对慢性颈痛患者进行治疗,观察患者颈部肌肉力量是否得到增强,以及颈椎的Cobb角是否得到改善。方法将符合纳入标准的30例慢性颈痛患者纳入研究对象（PNF组）。研究对象接受为期4周的PNF技术治疗,对比治疗前（基线）和治疗4周后颈部最大等长收缩肌力（MIS）,并比较治疗前后Cobb角。结果共30例患者完成研究。治疗后颈椎Cobb角明显改善,治疗4周后对比基线Cobb角差异具有统计学意义（t=4.925,P<0.001）。颈椎屈曲和伸展的力量经过4周治疗后都得到明显的改善,颈椎伸展的MIS从（15.8±2.5）lbs增加到（19.3±3.1）lbs,比较基线差异具有统计学意义（t=5.685,P<0.001）。颈椎屈曲的MIS从13.9（10.3,15.6）lbs增加到17.8（15.3,18.8）lbs,治疗4周后对比基线差异具有统计学意义（Z=-4.783,P<0.001）。结论 PNF技术能有效增强颈部肌肉力量,可有效增大颈椎Cobb角,可能为颈椎变直的慢性颈痛患者的治疗带来积极的影响。

Abstract: Objective To observe whether the strength of the neck muscles and the Cobb angle of the cervical vertebra are improved by proprioceptive neuromuscular facilitation（PNF）in the treatment of patients with chronic neck pain. Methods Thirty patients with chronic neck pain who met the inclusion criteria were included in the study group（PNF group）. They were treated with PNF for four weeks,maximal isometric strength（MIS）and Cobb angle in the neck were compared at before（baseline）and four weeks after treatment. Results A total of 30 participants completed the study. The Cobb angle of cervical spine was significantly improved after treatment,and the Cobb angle before treatment was significantly different from that after four weeks of treatment（t=4. 925,P<0. 001）. The strength of cervical flexion and extension improved significantly after four weeks of treatment,and the MIS of cervical extension increased from（15. 8±2. 5）lbs to（19. 3±3. 1）lbs,which was statistically significant compared to baseline（t=5. 685,P<0. 001）. Cervical flexion MIS increased from 13. 9（10. 3,15. 6）lbs to 17. 8（15. 3,18. 8）lbs,and the difference was statistically significant compared to baseline after four weeks of treatment（Z=-4. 783,P<0. 001）. Conclusions PNF can effectively enhance the strength of neck muscles,and can effectively increase the Cobb angle of cervical spine,which may have a positive impact on the treatment of chronic neck pain patients with cervical straightening.
