Abstract
Background: Impaired cardiac autonomic system is one of the common problems among children with cerebral palsy (CP) which may be associated with low physical tolerance. Purpose: This study was conducted to investigate the response of cardiac autonomic system to sub -maximal test and the effect of sub-maximal test on muscle fatigue in children with spasticity.Subjects: Thirty children with spastic CP (23 boys and 7 girls) participated in the present cross-sectional study. They were divided into two groups of equal number (15 in each). Children with spastic hemiplegia in group A while children with spastic diaplegia in group B. They were selected at level I and II according to Gross Motor Function Classification System (GMFCS), and the degree of spasticity ranged from 1 to 1+ according to Modified Ashworth Scale .Response of cardiac autonomic system via monitoring of heart rate (HR) and heart rate variability (HRV) was assessed by the Polar Advanced Heart Rate Monitor (RC800CX) at different time intervals pre, during and post sub-maximal test, while muscle fatigue of quadriceps and hamstring muscles was assessed by using isokinetic dynamometer pre and post sub-maximal test
