Background: children with cerebral palsy are at risk for decreased mobility and health complications, and exercise may combat some of these negative changes. Objective: To investigate the effect of balance training versus reciprocal electrical stimulation on motor control of knee joint controlling in spastic diplegic cerebral palsied children Methods: Thirty children were enrolled in this study and randomly assigned into two groups of equal number. Group A include 15 spastic diplegic cerebral palsied children who received a course of balance training program that include static and dynamic postural stability training- for thirty minutes plus traditional physiotherapy program- Group B include 15 spastic diplegic cerebral palsied children who received reciprocal electrical stimulation above knee joint flexors and extensors muscles for thirty minutes in addition to the same traditional physiotherapy program in group (A) three days per week for three moths, Standard plastic goniometr was used to detect and follow knee extension from the point of flexion deformity, flexibility tests was used to detect hamstring, gastrocnemius and gracillis muscles flexibility in addition 10 tape measurement was used alternatively to measure distance between the heel to buttock at the point of extension limitation. These measure means were taken before initial treatment and after 12 weeks of treatment. Results: Revealed statistically significant improvement in the measuring variables of both groups when comparing their pre and post treatment mean values. Significant differences in the measured variables were also obtained in favor of the group (A) when compared with that of group (B). Conclusion: The use of balance exercise program are superior to reciprocal electrical stimulation for all measurement that include knee mobility and hamstring and gastronomies flexibility.
