* Etiologies could not be determined in all patients in the studies listed in section a and in some patients more than one category of etiology was given. In some studies there were no data provided as to a specific etiology.
SQ = spastic quadriplegic; M = mixed; SD = spastic diplegic; NA = not available; D = dyskinetic.
