Hemiplegia is paralysis, meaning a reduction or total cessation of body motion, which affects one of its sides. It can impact uniformly across the side of the body, face, upper limb, or lower limb in which case it is called proportional hemiplegia, or one or more of these parts. Right hemiplegia refers to a paralysis of the right side of the body and is a symptom of an attack on the left side of the brain. In general, the left hemisphere of the brain is the dominant hemisphere. In cases of injury to the dominant hemisphere, some other clinical signs may be present in relation to the specific functions of this part of the brain. These signs include aphasia, speech disorders, and apraxia, disorders of the execution of movements.
