Abstract: ob＜x＞jective To explore the effect of gargle exercise on the recovery of neck function in patients with thyroid cancer after operation. Methods from August 2018 to August 2019, 116 patients with postoperative thyroid cancer were randomly divided into observation group and control group, 53 cases each. The control group was given routine neck exercise, and the observation group was given gargle exercise on the basis of the control group. The compliance, neck activity and the incidence of cicatricial contracture were compared between the two groups. Results the compliance of the observation group was better than that of the control group after one week’s intervention (P < 0.05). After one week of intervention, the activity of the neck in the observation group was higher than that in the control group (P < 0.05). The incidence of cicatricial contracture in the observation group was lower than that in the control group after one month intervention (P < 0.05). Conclusion gargle exercise can effectively improve the compliance of exercise, improve the activity of neck and reduce the incidence of cicatricial contracture.
