The clinical manifestations of children with spastic cerebral palsy mainly include: 1, lack of activity in the lower limbs, especially alternating movements; 2, in the strengthening of the detrusor reflex, so that the muscles feel obvious resistance when moving suddenly and passively, followed by muscle relaxation to a certain degree, and the increase of the spastic state when stretching the muscles will cause excessive muscle contraction spasms, and the tendon reflexes of the muscles are hyperactive, and myoclonus may appear, suggesting a response to the detrusor reflex Strengthened; 3, from the posture, whether in the supine or prone position, both lower limbs have inward, internal rotation; foot is pointed foot, inversion or valgus, for this reason the infant prone less stable, sitting position because of the leg inward internal rotation, can not be separated, flexion, free activity stretching difficult to do lower limb extension and full flexion, joint, so to the front of the leg extension, sitting position difficult; 4, for both lower limbs hyperreflexia, ankle clonus positive, upper limbs The symptoms of hyperreflexia spasticity are also present. The lower limbs are pointed foot deformity, generally have a tendency to inversion, in the anti-gravity muscle strength, such as thigh quadriceps muscle strength is weakened, the three-dimensional position can be turned out, appear flat foot; knee is generally flexion, when the resistance muscle strength is strong, the standing position can appear hyperextension, recoil, and other deformities.
