Abstract：Objective To investigate the effect of multi-angle resistance training combined with cervical traction on cervical physiolog-ical curvature,Neck Dysfunction Index(NDI)score,Visual Analogue Scale(VAS)score,active range of motion of the cervical spine,and electromyography parameters of cervical muscle surface in patients with cervical spondylosis.Methods A total of 130 patients with cervical spondylosis admitted to Taihe Hospital from January 2021 to December 2022 were randomly allocated to the control group and study group,with 65 cases in each group.The patients in the control group received cervical traction,and the pa-tients in the study group cervical muscle multi-angle resistance training combined with cervical traction.The clinical efficacy,cervical physiological curvature,NDI score,VAS score,and cervical muscle surface electromyography results before and after treatment were compared between the two groups.Results The overall response rate of the study group was significantly higher than that of the control group[92.31％(60/65)vs.80.00％(52/65),X2=4.127;P=0.042].Before treatment,the difference in the physi-ological curvature of the cervical vertebra between the two groups was not statistically significant(P＞0.05);after treatment,the physiological curvature of the cervical vertebra in the two groups was significantly increased,and the study group was significantly higher than the control group(P＜0.05).Before treatment,no significant difference was observed in NDI and VAS scores between the two groups(P＞0.05);after treatment,NDI and VAS scores in the two groups were significantly reduced,and the study group was significantly lower than the control group(P＜0.05).Before treatment,no significant difference was detected in the range of motion of flexion,extension,flexion on both sides,and rotation on both sides between the two groups(P＞0.05);after treatment,the range of motion of flexion,extension,flexion on both sides,and rotation on both sides in the two groups was signifi-cantly greater than that before treatment,and the study group was significantly greater than the control group(P＜0.05).Before treatment,no significant difference was found in electromyographic amplitude and median frequency between the two groups(P＞0.05);after treatment,electromyographic amplitude in both groups was significantly reduced and the study group was significantly lower than the control group;median frequency was significantly increased and the study group was significantly higher than the con-trol group(P＜0.05).Conclusion Multi-angle resistance training combined with cervical traction can effectively reduce the pain and potentiate the physiological curvature of cervical vertebra and neck function in the treatment of cervical spondylosis.These ad-vantages hold promise for a wider clinical application.
