What is defined as paralysis of one half of the body?

• A. Hemiplegia
• B. Dysphasia
• C. Pronator drift
• D. Vertigo

Answer: (A)

Hemiplegia refers specifically to paralysis on one side of the body, often resulting from a neurological condition such as a stroke or traumatic brain injury. This condition affects mobility and coordination, making it challenging for individuals to move limbs or perform daily activities on the side of the body that is paralyzed.

Dysphasia pertains to difficulty in speaking or understanding language, which is not related to paralysis. Pronator drift is a clinical test used to assess motor function and strength in the arms but does not denote paralysis. Vertigo is the sensation of spinning or dizziness, often associated with inner ear issues, and does not describe a paralysis condition. Therefore, the definition of hemiplegia aligns perfectly with the description of paralysis affecting one half of the body.
