Which of the following is listed under hypertonicity as a cerebrovascular event?

• A. CVA (Cerebrovascular Accident)
• B. Cerebral palsy
• C. Spinal cord injury
• D. Brain tumors

Answer: (A)

Hypertonicity often follows an upper motor neuron disruption. A cerebrovascular event, such as a stroke, damages brain areas that normally regulate muscle tone, leading to increased tone (spasticity) on the affected side. Among the options, the cerebrovascular accident is the one that represents a vascular event involving the brain, matching the scenario described.

Cerebral palsy is a developmental motor disorder with increased tone but is not an acute cerebrovascular event. Spinal cord injury is trauma to the spinal cord, not a brain vascular event. Brain tumors are growths in the brain, not vascular events.
