Diplegia

Diplegia, when used singularly, refers to paralysis affecting symmetrical parts of the body. It can involve any body area, such as both sides of the face, both arms, or both legs. It is different from hemiplegia which refers to spasticity restricted to one side of the body, paraplegia which refers to paralysis restricted to the legs and hip, and quadriplegia which requires the involvement of all four limbs but not necessarily symmetrical.
