There are many types of cerebral palsy because of the different factors that trigger it. Spastic cerebral palsy is one of the more common types. The lesion of spastic cerebral palsy is in the cone ito, and the injury to the cone system is the main cause. In the following, we will ask experts to analyze the characteristics of spastic cerebral palsy: 1. Due to the hyperactive detrusor reflex, the symptoms of spastic cerebral palsy are manifested clinically as hyperactive tendon reflex, hyperactive Achilles tendon reflex, ankle clonus, etc. When the joint is passively extended, there is a folding knife-like sensation, which is called the folding knife sign. 2, manifested in the muscle group, due to the tension reflex hyperactivity, causing persistent muscle tension in a hyperactive state, posture, abnormal movement, joint deformation, contracture. A variety of factors can affect the degree of muscle tension, such as the intensity of the stimulus, the excitability of the child, etc. If the muscle tension is increased, the muscles around the impaired area, such as the scapula and hip joint, contract strongly and simultaneously, and a typical fixed posture can occur. Weakening of a certain group of muscles may occur due to the opposite neuroinhibitory barrier that antagonizes the muscle spasm. Understanding the characteristics of spastic cerebral palsy can be very useful in its later treatment. Children with spastic cerebral palsy have a small range of motion and are often confined to the center of the body. Often, children with this type of cerebral palsy have a strong fear and sense of restlessness, fear of falling, and fear of sudden stimulation by high sounds. Due to the parents’ and the child’s own condition, the child has very little exposure to the outside world and a small range of motion, so it is difficult for the child to adapt to physical, mental and environmental changes.
