ABSTRACT
Cerebral Palsy [CP] is a neurodevelopmental disorder caused by non-progressive lesions in single or multiple locations in the immature brain. Lesions of motor cortex and pyramidal tracts can lead to spasticity. Inhibition of spasticity is necessary to increase extremity mobilization, prevent postural abnormalities and provide independence in daily living activities. The purpose of this study was to determine the effects of volar static splint spasticity and range of motion of upper extremity in children with Cerebral palsy in three periods of time. The design of this study was experimental and repeated measurements. Ten children with Cerebral palsy aging 4-6 years old were non-randomly selected among children referred to occupational therapy Clinic of rehabilitation Faculty of Tehran University of Medical Sciences. Children used dorsal static splint for three months [2 hours at day and 4 hours at night]. In this study, Modified Ashworth Scale was used to evaluate spasticity and a Goniometre was used to measure passive range of motion. The results of this study showed significant reduction in the upper limb spasticity after 2 months [p
