Small localized exercises can be started 1 day after nail cancer surgery, and larger full neck exercises can be performed after about 1 week. The wound of thyroid cancer surgery is located in the neck, so it is necessary to start neck exercise at an early stage in order to reduce the postoperative tissue adhesion and contracture. In the early postoperative period (1 day~1 week after surgery), adhesion in the throat is easy to appear, and appropriate exercise can be started. At this time, the wound is still in the process of healing, and a larger exercise may lead to wound dehiscence and blood seepage, and local exercises such as swallowing and small lateral bending of the neck can be carried out. In the middle postoperative period (1~3 weeks after surgery), contracture of scar tissue may easily occur, resulting in stiffness and concave deformity of the neck, etc. At this time, you can carry out exercises focusing on side neck function. At this time, you can carry out neck exercises that focus on side neck function, such as larger neck bending, head turning, shoulder shrugging, neck flap pushing and other movements. In the late postoperative period (3 weeks after surgery), you can increase the magnitude and intensity on the basis of the mid-term exercise, and increase the expansion of the chest, head like the healthy side side bending and other training. Postoperative neck exercise helps wound healing and recovery of upper limb, shoulder and neck functions. It is recommended that patients start neck exercise in the early postoperative period, and consult a specialist in case of pain and activity limitation.
