hemiparesis

Full Definition

Partial weakness or reduced strength affecting one side of the body, including the arm, leg, and sometimes facial muscles. Hemiparesis is less severe than hemiplegia and allows for some voluntary movement, though with reduced power and coordination. This condition commonly results from stroke, brain injury, or other neurological conditions affecting the motor pathways.

Usage

Usage note: Indicates weakness, not complete paralysis. Often graded on 0-5 scale.
