What is hemiparesis?

Explanation:
Hemiparesis is weakness on one side of the body. This occurs when motor pathways in the brain or brainstem are damaged, such as after a stroke, and the weakness is typically on the opposite side of the body due to the crossing of many motor fibers. It is not a complete loss of movement—that would be paralysis (hemiplegia). It’s also not sensory loss, like numbness on one side, nor is it a bilateral tremor. In exam terms, you’d look for reduced voluntary strength on one side, often with corresponding motor findings, while sensory deficits or bilateral tremor point to different patterns of impairment.
