What is a common symptom of spastic CP?

Spastic cerebral palsy (CP) is characterized by increased muscle tone and stiffness, which leads to rigid, stiff, abrupt, and jerky movements. This occurs due to damage to the parts of the brain that control voluntary movement, particularly the motor cortex. Individuals with spastic CP often experience difficulty in controlling their muscles, resulting in movements that are not fluid and may appear awkward or uncoordinated. The rigidity and stiffness in their muscles can greatly impact their ability to perform tasks and can affect posture, movement patterns, and overall mobility. This symptom is a defining characteristic of spastic CP, distinguishing it from other types of cerebral palsy, which may present with different movement issues.

The other options describe symptoms that are not typically associated with spastic CP; for example, visual perception difficulties, seizures, and hearing impairments can occur in various conditions but are not hallmark signs of spastic cerebral palsy specifically.
