Which term describes the feature of altered muscle tone associated with spasticity in cerebral palsy?

The correct term that describes the altered muscle tone associated with spasticity in cerebral palsy is hypertonia. Hypertonia refers to an increased level of muscle tone, resulting in stiff and tight muscles that can hinder movement. In individuals with cerebral palsy, spasticity is a common characteristic where certain muscle groups are excessively contracted while others may not be, leading to difficulties in mobility and coordination.

This phenomenon can indeed restrict the range of motion and cause discomfort or pain, making it a prominent feature in the physical presentation of cerebral palsy. Hypertonia can significantly impact a person's ability to engage in daily activities and may require therapeutic interventions to manage the symptoms effectively.
