A new evaluative measure of motor and sensory function was developed for children with epilepsy aged six to 16 years. The bases for the measure were theories of normal motor development and motor control, and the conceptual framework was the World Health Organization's International Classification of Impairments, Disabilities, and Handicaps. The assessment protocol has 59 items, including gross motor function, gait, balance, coordination, strength, range of motion, velocity, fine motor function, sensation, perception, and performance on neurological tests. The quality and level of sensorimotor function were scored. Classification of handicap was included in the test. Intrarater and interrater reliability were evaluated and found to be good (rs≥ 0.9). The test was administered to 274 children, and evidence of good content validity, criterion-based/ concurrent validity, construct validity, and responsiveness to change was found. The test was found to be a useful measure of motor and sensory function in this heterogeneous population of children with epilepsy involved in an epilepsy surgery program.
