Deterioration can occur secondary to musculoskeletal impairments.
For the most part, medical or rehabilitation treatment do not
lessen the severity of the condition, or assist a person to
improve up into a milder Gross Motor Function Classification
System level. Without rehabilitation and orthopedic management,
a person can deteriorate physically and drop down a full
Gross Motor Function Classification System level; therefore, it
is very important to refer children to rehabilitation, developmental
services, and orthopedic surgery.
