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.
