Acuity card testing of spastic children: preliminary results.

Acuity card testing of spastic children showed a high success rate. Agreement between repeated tests for children with mild motor handicaps was within the limits reported for non-handicapped children. Although more of the children with severe motor handicaps had greater test-retest variabilities, the majority of results from this group also showed an acceptable agreement. The high success rate and good test-retest agreement indicate that acuity cards can be very useful for testing children with cerebral palsy, who often have reduced acuity.
