CP describes a group of permanent disorders of the development of movement and posture, causing activity limitation. The motor disorders of cerebral palsy are often accompanied by disturbances of sensation, perception, cognition, communication, and behavior, by epilepsy, and by secondary musculoskeletal problems.
In a child with cerebral palsy, the damage tends to be in the area of the brain that controls muscle tone and movement of the arms and legs. Therefore, the brain is unable to influence the amount of muscle flexibility. The muscle command dominates the spinal cord and, as a result, the muscle is too stiff or spastic.
SDR is a neurosurgical procedure that involves selectively sectioning (cutting) of some of the sensory (dorsal) nerve fibers that come from the muscles and enter the spinal cord.
