Clinical characteristics of impaired trunk control in children with spastic cerebral palsy

Abstract

This study aimed to identify clinical characteristics of impaired trunk control in hundred children with spastic CP (mean age 11.4 ± 2.1 years, range 8-15 years). Assessment of trunk control was performed with the Trunk Control Measurement Scale (TCMS). Trunk control was clearly impaired, indicated by a median total TCMS score of 38.5 out of 58 (66%). Median subscale scores were 18 out of 20 (90%) for the subscale static sitting balance, 16 out of 28 (57%) for the subscale selective movement control and 6 out of 10 (60%) for the subscale dynamic reaching. Total TCMS and subscale scores differed significantly between topographies and severity of motor impairment according to the Gross Motor Function Classification System (GMFCS). Children with hemiplegia obtained the highest scores, followed by children with diplegia and children with quadriplegia obtained the lowest scores. TCMS scores significantly decreased with increasing GMFCS level. In conclusion, trunk control is impaired in children with CP to a various extent, depending on the topography and severity of the motor impairment. The findings of this study also provide specific clues for treatment interventions targeting trunk control to improve their functional abilities.
