Which factors can limit range of motion in individuals with cerebral palsy?

• A. ROM is never limited in CP.
• B. Nutritional status solely.
• C. Contractures, hypertonicity or spasticity, and shortened musculature due to postural deficits.
• D. Only joint age.

Answer: (C)

In cerebral palsy, range of motion is most often limited by soft-tissue and neural factors that alter how joints move. Contractures are a key contributor—permanent shortening of muscle-tendon units and surrounding tissues that lock a joint into a shortened position, reducing passive and active movement. Hypertonicity or spasticity adds resistance to movement from the nervous system, so the limb stops moving before it would with normal tone. Shortened musculature due to sustained abnormal postures and imbalances also narrows how far a joint can move because muscles become habitually tight and pull joints into fixed positions. Nutritional status and simply getting older do not directly cause ROM limitations in CP; ROM changes are driven by these tissue and tone-related factors and the patterns of postural use that develop over time.
