What term describes a partial paralysis affecting a body part?

The term that describes a partial paralysis affecting a body part is "paresis." This word specifically refers to weakness or partial loss of muscle strength and function, distinguishing it from complete paralysis, which is referred to as "plegia." Paresis can occur in various parts of the body and may affect a limb or specific muscle groups, leading to difficulty in movement and control.

In contrast, paraplegia refers to the paralysis of the lower half of the body, typically affecting both legs, while quadriplegia involves paralysis of all four limbs, usually resulting from spinal cord injury or disease. Hemiplegia denotes paralysis that affects one side of the body, often as a consequence of a stroke or neurological condition, resulting in one arm and one leg being affected. The specific nature of paresis makes it a more appropriate term for partial paralysis.
