Cerebral Palsy (CP) is a major cause of motor disability in children. Among these CP children, approximately one third have hemiparetic cerebral palsy. Hemiparetic cerebral palsy is more impairment of one side of the body as a result of non-progressive disturbances in premature brain.To determine the effects of implementing a practice period of modified constraint induced movement therapy in a virtual environment on hand function in chidren with hemiparetic cerebral palsy.

To determine the effects of implementing a practice period of modified constraint induced movement therapy in a virtual environment on hand function in chidren with hemiparetic cerebral palsy.The term Modified constraint-induced movement therapy is a form of rehabilitation therapy that limits the less paretic side, and through repeated and concentrated training improve the upper limb function of the paretic side. Motor imagery is a cognitive process in which a subject imagines that he or she performs a movement without actually performing the movement and without even tensing the muscles. Modified Constraint induced movement therapy can be utilized in both the lower and upper extremities with the motor imagery technique for psychological or occupational therapy and in affecting which one is better for speedy recovery.

Inclusion Criteria:

• Age 6 to 14 years were included.
• Diagnosed of hemiparetic cerebral palsy and typically developing controls.
• Both gender is included i-e, male and female.
• Children included having motor impairments of upper limb.
• All children had normal or corrected vision and the ability to discriminate between right and left.

Exclusion Criteria:

• History of neurosensory and neuropsychiatric impairments.
• Presence of contractures in the affected upper limb.
• Surgery in the previous six months.
• Uncontrolled epilepsy

Participants will get separate treatment protocols and possible efforts will be put to mask the both groups about their treatment.
