Introduction: In Cerebral Palsy the areas of the brain affected are those associated with the motor systems, which when damaged, impair control of movement. The difficulties of a child with Cerebral palsy are caused with either damage to or faulty development of the motor areas of the brain that disrupts the brain’s ability to control movement and posture producing poor coordination, poor balance, or abnormal movement patterns. Over the decades, studies related to intermanual transfer have been performed in normal subject. The main objective of this study is “to find out the effect of strengthening of unaffected upper extremity on motor performance of affected upper extremity in spastic hemiplegic cerebral palsy”. Methodology: 20 spastic hemiplegic CP subjects aged 515 years, IQ > 60 were taken and divided in two groups. Control group was given Conventional exercises for affected upper extremity and experimental group was given strengthening and coordination training to unaffected upper extremity while affected limb received the same treatment as control group. Intervention was given for three days a week for 3 weeks.The subjects were assessed using Purdue Pegboard test and Abilhand assessment tool before and after the intervention. Results: The experimental group showed significant effect on purdue pregboard task and abilhand tool after the training. Discussion: Intermanual transfer of training does exist in patients with spastic hemiplegic CP leading to improvement in motor performance.
