hemiplegia
Pronunciation: hem-i-PLEE-jee-uh
Complete paralysis of one side of the body, typically following stroke or brain injury.
Full Definition
Hemiplegia is complete paralysis affecting one side of the body, usually involving the arm, leg, and sometimes the face on the same side. This condition most commonly results from stroke affecting the contralateral motor cortex or corticospinal tract, but can also occur due to traumatic brain injury, brain tumors, or infections. The paralysis is typically accompanied by increased muscle tone (spasticity) and hyperreflexia due to upper motor neuron damage. Hemiplegia differs from hemiparesis, which refers to weakness rather than complete paralysis on one side of the body.
Usage
Usage note: Distinguish from hemiparesis (weakness) and specify the affected side in documentation.
