A California study has found just 7 percent of cerebral palsy patients living independently or semi-independently, federal health authorities said.

A check of 11,050 adult cerebral palsy patients in California in 1988 found 24 percent living in state-run centers, 38 percent in group quarters for four to 50, 32 percent with parents or guardians and 7 percent at least somewhat on their own.Findings were reported by the Centers for Disease Control. While the findings may not be statistically representative of California or the United States, the study indicates areas for improvement, the CDC said.

"Placement of persons with substantial disabilities into less restrictive environments is an important goal" to encourage developmental growth and social skills, the CDC said.
