Spastic cerebral palsy is one of the types of cerebral palsy and the most common type, accounting for approximately 80% of the total number of patients with cerebral palsy. Spastic cerebral palsy is extremely common as a type of cerebral palsy, and the treatment for this type of patient clinically insists on surgery + rehabilitation. The surgical treatment refers to FSPR surgery to relieve the spasticity of the patient. The main purpose of FSPR surgery is to adjust the muscle tone of the patient in a comprehensive manner, so that the muscle tone of the spastic muscles is as close to normal as possible. Intraoperative monitoring is performed through multi-conductor electrophysiological technology to determine the proportion of spinal nerve posterior roots to be removed, making the scope and proportion of sensory nerve removal more scientific and objective, creating opportunities and providing possibilities for functional improvement and correction of abnormalities in patients with spastic cerebral palsy and patients with mixed cerebral palsy whose main symptom expression is spasticity! FSPR surgery has strict clinical indications, such as the patient is constant and the muscle strength is above grade 3, and the patient has certain motor function of trunk and limbs. In addition, for patients with spastic cerebral palsy, some preoperative preparations are needed before surgery. The rehabilitation training method can be referred to the following steps: passive and active lower limb joint activities can be performed 3 days after surgery, and passive movements are applied to the lower limb extensor and flexor muscle groups to promote functional rehabilitation. Hip flexion, extension, separating the two thighs and straightening the two knees. 3 weeks later, the patient’s sitting balance ability and trunk adjustment ability can be trained. Four to six weeks after surgery, the patient can be trained to stand on the ground with assistance or against the wall, keeping the upper body flat, the hip and knee joints straight, the legs slightly apart, and the feet flat on the ground. On the basis of standing, support the patient to do striding training, or use rehabilitation equipment such as walkers, single crutches, double crutches, etc. to train striding. Use balance boards, up and down hills, sponge mats and stairs for walking training, so that the patient can constantly adjust the posture and position of the trunk and limbs to exercise the balance of gravity. Using the knee rocking chair, patients can strengthen the knee flexion, knee extension, plantarflexion and dorsiflexion training to further strengthen the semitendinosus, semimembranosus, biceps femoris, quadriceps and triceps calf and tibialis anterior muscles. FSPR surgery only effectively relieves limb spasticity, and postoperative training is an important guarantee to improve the efficacy of surgery and restore potential functions. The treatment plan for cerebral palsy patients who implemented rehabilitation training before and after surgery to achieve satisfactory results was to follow the training-surgery-retraining model, with preoperative functional training followed by FSPR surgery. The rehabilitation treatment for cerebral palsy patients must be done in close cooperation and collaboration among medical care, patients and family members.
