This clinical trial aims to Compare the effectiveness of lower limb CIMT and the Strength Training of the Non-Hemiplegic lower limb on motor performance in hemiplegic children with CP.

Participants will:

diagnosed with hemiplegic cerebral palsy treated with CIMT or Strength training (cross-education) for a non-hemiplegic limb for 8 weeks.

Method:

32 children with hemiplegic CP will be equally and randomly allocated to two groups (group A and B). group A will receive lower limb CIMT for the non- hemiplegic limb using whole leg orthosis and Group B will receive strengthen training for the non-hemiplegic lower limb. Both groups will receive routine physical therapy for the hemiplegic lower limb. Both groups will receive 60 minutes training session for 3 sessions per week for 8 consecutive weeks. Assessment will be at baseline then at the end of trial.
