Effectiveness of Constraint-induced Movement Therapy on Hand Function in Cerebral Palsy Children: A Narrative Review

A neurodevelopmental disease known as Cerebral Palsy (CP) first manifests in infancy and affects a variety of developing abilities, including motor control, coordination, tactile perception, cognition, and attention. The most prevalent type, accounting for 60%-70% of cases, is spastic CP. Ataxic CP accounts for 10%-15%, athetoid CP for 10%-15%, and mixed CP for 10%. Children diagnosed with hemiplegia exhibit firmness and muscle weakness due to unilateral involvement of both upper and lower limbs on the opposite side of the brain lesion. These variables may manifest upper limb motor deficits, such as restricted grasp, reach, and manipulation. These disabilities result in functional restrictions during daily activities and may cause the affected extremity to be underutilised. Hand impairment in hemiplegic CP occurs from damage to the motor cortex and corticospinal pathways, which are in charge of fine motor control of the fingers and hand. In terms of enhancing fine motor abilities and improving functional results, it has been demonstrated that Constraint-induced Movement Therapy (CIMT) is useful for individuals with CP. CIMT involves teaching a child to use their affected hand by using a constraint on the unaffected hand and repetitive extensive implementation of movements with the affected hand. The aim of the present review was to find out how CIMT affected the hand functionality in children with CP.
