An investigation of the effect of the lower extremity sensation on gait in children with cerebral palsy

Abstract

Background: Sensory disorders frequently accompany the motor disorders in children with cerebral palsy (CP). Research question: Do children with CP have sensory disturbances in their lower extremities? If there are sensory impairments, do these impairments affect gait? Methods: In total, 45 children (18 females, 27 males) in an age range between 5 and 18 years were included in the study: 15 typically developing children, 15 unilaterally affected children with cerebral palsy, and 15 bilaterally affected children with cerebral palsy. They could walk independently at the levels of I or II according to the gross motor function classification. After the demographic data of the children were recorded, their tactile sense, vibration sense, two-point discrimination, and proprioception were evaluated, and the Edinburgh Visual Gait Score (EVGS) was used for gait assessment. Results: Failures were discovered in lower extremity tactile (p = 0.001), two-point discrimination (p = 0.001), and proprioceptive senses of the children with CP (p = 0.001), and the loss of tactile sense was found to be related to gait disorders (p = 0.02, r = 0.41). Significance: There were deficiencies in the lower extremity senses, and deficiencies in the tactile sense negatively affected gait. Performing sensory assessments, which are considered to be fundamental for gait training in the rehabilitation of children with CP, and providing support for the lacking parameters in the intervention programs may create positive effects on gait.
