Unilateral paralysis is a medical condition that occurs when one side of the body is paralyzed due to damage to the nerve or muscles. There are various terms that can be used to describe this condition, including hemiplegia, hemiparesis, and monoplegia. Hemiplegia refers to complete paralysis of one side of the body, including the arm, leg, and face. Hemiparesis, on the other hand, is partial paralysis or weakness on one side of the body. Monoplegia refers to the paralysis of a single limb, such as an arm or a leg. Whatever the terminology used, unilateral paralysis can be a challenging condition to manage, requiring specialized care and support.
