Which condition is commonly associated with hypertonicity?

• A. Cerebral palsy
• B. Down syndrome
• C. Prader-Willi syndrome
• D. Angelman syndrome

Answer: (A)

Hypertonicity means increased muscle tone, often due to disruption of upper motor neuron pathways that regulate movement. In developmental motor disorders, the most典ic example of this hypertonic pattern is cerebral palsy, which commonly presents with spasticity—a form of hypertonia affecting the limbs and trunk. This reflects the typical brain motor control disturbance in CP, leading to stiff, resistant passive movement and movement coordination challenges. Down syndrome usually shows hypotonia in infancy, with reduced muscle tone that can improve or persist unevenly over time. Prader-Willi syndrome is characterized by early hypotonia and poor trunk tone, followed by other features, rather than persistent hypertonicity. Angelman syndrome also presents with hypotonia among other neurodevelopmental signs. So, among the options, cerebral palsy is the condition most characteristically associated with hypertonicity.
