What term is used for paralysis of one side of the body?

The term used for paralysis of one side of the body is hemiplegia. This condition occurs when there is damage to the brain or spinal cord affecting motor control on one side, typically resulting from a stroke, traumatic brain injury, or various neurological conditions. Hemiplegia leads to weakness or complete loss of voluntary movement on the affected side, which can significantly influence a person's mobility and daily activities.

In contrast, quadriplegia refers to paralysis affecting all four limbs, while paraplegia involves paralysis of the lower half of the body, usually affecting both legs. Diplegia means paralysis affecting symmetrical parts of the body, often seen in both legs or both arms, rather than impacting just one side. Understanding these terms is crucial for recognizing the implications of different types of paralysis in patient care and rehabilitation.
