Effect of locomotor training and functional electrical stimulation on postural function in children with severe cerebral palsy

详细

Cerebral palsy (CP) considerably impairs the ability to maintain upright stance. The effects of locomotor training and functional electrical stimulation (FES) on postural control were determined in 27 children aged 6–12 years with severe CP. The severity level of the clinical manifestations of CP was classified as 3 according to the Gross Motor Function Classification System (GMFCS). All patients participated in 15 30-min mechanical therapy sessions using robot-assisted passive stepping. In 12 out of 27 children, the locomotion therapy was accompanied by FES. Stabilometry and plantography tests were performed in 23 healthy age-matched children. Postural control in children with CP differed from the stabilograms of healthy children in a forward shift of the center of pressure (COP) projection; higher values of the COP trajectory area and length, the mean amplitude of the COP oscillations, and the absence of COP response to the eyes closed condition. After treatment, the posturographic characteristics tended to normalize in relation to the values obtained in neurologically intact children. The improvement was observed in 43% of children without FES and in 75% of children in the group with FES. Analysis of plantograms revealed normalization of footprints in children who received FES. Thus, it was demonstrated that FES combined with locomotor training resulted in the improvement in vertical posture control in children with severe CP.
