Tactile and pain disorders in children with cerebral palsy

  In addition to auditory and visual impairments, children with cerebral palsy also have other sensory impairments, although the incidence of these impairments is much lower than the first two.  About 10% of children with cerebral palsy may have loss of tactile sensation and loss of physical sensation. In postnatal acquired spastic unilateral palsy, the incidence of tactile loss is almost one times higher than in congenital spastic unilateral palsy. Specific manifestations: Inability to distinguish various objects or the shape of objects by hand touch only.  Most of the patients have dull joint sensation, and a few of them even have no sensation at all. Tendon reflexes are hyperactive; abdominal wall reflexes are weak, and in a few patients, they are not elicited. Spastic cerebral palsy has obvious deep sensory impairment, while superficial sensation is basically normal.  Among the studies on sensory disorders in children with cerebral palsy, more attention has been paid to auditory and visual disorders, which have a high prevalence, while tactile disorders have a prevalence of 10%, but special studies on them are still lacking or even unattended. Other senses, such as smell and proprioception, have not yet been studied. This shows that the research field of children with cerebral palsy is very broad, and there is still a lot of unexplored virgin land that needs to be researched.
