The Effect Of Somatosensory Perceptıon And Proprıoceptıon On Upper Extremıty Functıonal Skılls

In neurodevelopmental theory, sensory and motor systems mutually support the development of each other. In addition to the motor problems observed in SP; Sensory-motor impairment, which occurs with the effects of systems such as proprioception, tactile (touch), and vestibular (balance), emerges as the main problem. With the involvement of the central nervous system (CNS) in CP, the sensory systems are also affected along with the motor systems. The involvement of the sensory system is seen in 45% of these children and presents with a white matter lesion. One of the important factors affecting the activities of daily living (ADL) in children with Cerebral Palsy is the deficiencies in their functions as a result of the affected upper extremity. Deficiencies in sensory input can cause delays in learning new motor movements. This can result in disuse of the extremities and sensitivity. The somatosensory cortex, which is important for sensory integration; It is the area of the brain that is sensitive to tactile sensations from the body. It is known that the somatosensory system, which carries these tactile stimuli to the somatosensory cortex, is active from the early stage of life. Sensory and motor interactions experienced in the early stages of life are important for motor development even in the early stages. The improvement in measurable cortical responses of the tactile system; It starts from the 8th week of intrauterine and continues until the postpartum period. In the newborn period, the infant's responses to tactile and proprioceptive stimuli play an important role in the development of motor, cognitive, social and communication skills during infancy and early childhood. The aim of this study is to investigate the effects of somatosensory perception and proprioception on upper extremity functional skills in children with hemiparetic and diparetic CP.
