All articles concerning cerebral palsy-based spasticity mobility impairments, except for the article on spastic diplegia, redirect here. Spasticity of these types is not to be confused with paralytic disabilities similarly affecting varying specific limbs and that tend to carry similar names.

Spastic quadriplegia, sometimes called spastic tetraplegia, is the version of spastic diplegia that affects all four limbs (arms and legs) rather than just the legs. It is defined by spasticity, rather than the paralysis that defines quadriplegia. As with all forms of spasticity, spastic quadriplegia, while affecting all four limbs more or less equally, can still contain within an individual specific case, parts of the body that are more spastic than others, such as one arm being tighter than another arm, and so forth. Spastic triplegia, meanwhile, involves three limbs (such as one arm and two legs, or one leg and two arms, etc.); spastic hemiplegia affects one or another entire side of the body (left or right); and spastic monoplegia involves a single limb.

For more on why spasticity behaves this way and is so different from person to person, see the main article on muscle spasticity.
