Which condition is commonly associated with hypertonicity that involves a brain injury?

• A. Brain Injury
• B. Cerebral palsy
• C. Spina Bifida
• D. Down syndrome

Answer: (A)

Hypertonicity arises when the brain’s upper motor neuron pathways lose normal inhibitory control, so muscle resistance to movement increases after brain injury. Because this item focuses on a condition that directly involves a brain injury and is commonly linked to increased tone, the direct brain injury itself is the best match among the options. Cerebral palsy can feature hypertonicity since it stems from early brain insults, but the stem emphasizes the brain injury as the defining factor, making brain injury the most fitting choice. Spina bifida and Down syndrome typically present with hypotonia or mixed tone rather than a primary, prominent hypertonic pattern, so they fit less with the classic hypertonia picture.
