Plegia refers to a loss of motor function in a specific part of the body, often due to damage to the nervous system. It can affect various areas, leading to conditions such as hemiplegia, which impacts one side of the body, or quadriplegia, which affects all four limbs. The severity and location of the damage determine the extent of the paralysis. The term is commonly used in medical contexts to describe the effects of strokes, spinal cord injuries, or neurological disorders. Rehabilitation and therapy are often essential for recovery, helping individuals regain movement and improve their quality of life.
