This study was conducted to determine the effect of coordination dynamic therapy on controlling spasticity and functional abilities of the affected upper and lower limbs in spastic hemiplegic cerebral palsied children. Subjects: Thirty spastic hemiplegic children ranging in age from six to eight years represented the sample of the study. The degree of spasticity ranged from 1 to 1+ grades according to the modified Ashworth scale. They were divided randomly into two groups of equal number (A and B). The two groups received a conventional physical therapy program; in addition group B received coordination dynamic therapy. A motion analysis system was used to determine the shoulder, elbow, hip, knee and ankle joints angles during stance phase, before and after four months of treatment. Results: The collected data at the end of treatment revealed significant improvement in the measured variables of the two groups, which was higher in favor of group B. Conclusion: significant improvement observed in group B may be attributed to the effect of coordination dynamic therapy which controlled and improved neurogenesis and functional cell through improvement of motor organization and relearning of the central nervous system.
