Actually…
Cerebral palsy is a group of movement disorders, and the various subtypes are spastic, ataxic, athetoid and mixed. These subtypes are often prefixed to monoplegia, diplegia, hemiplegia, triplegia and quadriplegia to describe which limbs are affected. (I myself have spastic quadriplegia)
Since spasticity is the most common type of cerebral palsy-- 70-90% of cases, it’s understandable that the spastic society would choose to name themselves that way, and I suppose it’s also understandable though regrettably so, that laymen would learn to label certain people as “spastics.” as the abnormal motor patterns involved are easily recognizable. I’m not sure that there is much value to “cerebral palsy” as a name-- the therapeutic techniques used tend to differ by subtype.
