A comparative experimental design was used. Children participating in this study were assigned into two equal groups, Thirty four children with diplegic Cerebral Palsy of both genders who have balance problems were selected to join this study with the following criteria:
1. all the children diagnosed as diplegic cerebral palsy.
2. Their age are range from 5 to 10 years old.
3. The degree of spasticity is between grade 1 or 1+ according to Modified Ashworth Scale (Charalambous ,2013).
4. They are at level I OR II on Gross Motor Function Classification System .
5. All the children were able to follow verbal command and instructions.
And Children were excluded in the presence of the following:
1. Children that suffer from epilepsy.
2. Severe visual and auditory problems.
3. Structural or fixed soft tissue deformities of Lower extremities.
4. Severe mental retardation.
5. Botox injection in the lower extremity in the past 6 months..
all the children will be assigned in one of two groups ( vestibular training group and dual task group ) the training will be continue for definite period of time , and the balance abilities for the children in each group will be assessed before and after the treatment completely ended and the result will be compared to conclude which group benefit more and have a greater balance improvement and the treatment that causes a greater improvement will be more recommended in the future physical therapy plan for treatment of diplegic cerebral palsied children.
the balance is assessed using HUMAC balance system and pediatric balance scale .
