| Home | Cerebral palsy may be classified either by the type of movement problem (spastic, athetiod, or hypotonic) or by the body parts involved (legs only, one arm and one leg, or all four limbs). Motor ability and coordination vary greatly from one child to another, and there are very few statements that hold true for all children with cerebral palsy Spasticity refers to the inability of a muscle to relax, while athetosis refers to an inability to control the movement of a muscle. Infants who at first are hypotonic, or very floppy, may latter develop spasticity. Hemiplegia is cerebral palsy that involves one arm and one leg on the same side of the body, whereas diplegia primarily involves both legs. Quadroplegia refers to a pattern involving all four extremities as well as trunk and neck muscles. Generally a child with quadroplegia does not walk independantly. Another frequently used classification is ataxia, which refers to balance and coordination problems. Although almost all children with cerebral palsy can be classified as having hemiplegia, diplegia, or quadroplegia, there are significant overlaps that have led to the use of additional terms, some of which are confusing. Occasionally you'll encounter terms like paraplegia, double hemiplegia, triplegia, and pentaplegia; these classifications are also based on the parts of the body involved. By type of movement: Spastic -- rigid Athetoid -- no muscle control Hypotonic -- floppy Ataxic -- balance and coordination problems Mixed By involved body parts Hemiplegia -- one arm and one leg on the same side of the body Diplegia -- predominantly both legs (arms also involved) Quadroplegia -- all four extremities Other terms used to define specific problems of involvement or muscle function include dystonia, tremor, ballismus, and rigidity. The words severe, moderate and mild are also often used in combination with both type of movement and involved body parts classification terms (severe spastic diplegia, for example), but these qualifying words do not have any specific meaning. They are subjective words, and their meaning varies depending upon the person who is using them. This site designed & maintained by D Angel's Web Design & Graphics.
