Hemiparesis

Hemiparesis is weakness on one side of the body. It is less severe than hemiplegia — the total paralysis of the arm, leg, and trunk on one side of the body. Thus, the patient can move the impaired side of his body, but with reduced muscular strength.

Hemiparesis can be caused by a number of medical conditions, most related to the brain or spinal cord. Some of the conditions that have hemiparesis as either an indicative symptom or as a result of the condition itself include migraine, head trauma, muscular dystrophy, stroke, brain tumors, or cerebral palsy.
