“…Impaired control of posture is the main component of the definition of CP 4 ) . The development of movement and posture may be altered by non-progressive damage to the brain and subsequent neurological impairments (spasticity, muscle weakness, co-contractions and visual impairment) 5 ) . Studies indicate that children and adults with both mild and severe forms of CP have postural impairments 6 , 7 , 8 ) .…”

[Purpose] The purpose of this study was to investigate the differences in symmetry of sitting posture between typical developmental (TD) children and hemi-cerebral palsy (CP) children. [Subjects and Methods] A school chair mounted on a force platform was used to assess the quiet-sitting pressure distribution of 10 TD and 10 CP children. [Results] The symmetry index of the TD children was significantly closer to zero than that of the CP children irrespective of the latter group’s hemiparetic side. [Conclusions] Sitting posture on school chairs of CP children was more asymmetrical than that of TD children.

“…The understanding of the effect that sensory information has on postural control in children with CP, particularly during the performance of functional activities, can better inform exercises performed during therapy , thus enhancing children's levels of functionality (Pavão, dos Santos, Oliveira, & Rocha, 2013). By receiving specific and suitable sensory cues during rehabilitation, such children can increase their postural control, functional activities, and, therefore, may improve their interaction with the environment and social involvement (Liao & Hwang, 2003;Woollacott & Shumway-Cook, 2005).…”

Impairments in sensory processing in children with cerebral palsy (CP) appear to be a cause of the postural control deficits they present and may affect function and participation in daily activities. Understanding the role of sensory processing in postural control can better inform their rehabilitation. Thus, the authors aimed to systematically review the literature concerning effects of sensory information manipulation on postural control in children with CP. A tailored search strategy in relevant databases identified 11 full-text reports that fulfilled the predefined inclusion and exclusion criteria. Sensory information affects postural control in children with CP. These children are less responsive to sensory input, and therefore are less able to perform adjustments during sensory perturbation. They exhibit less postural stability in the presence of sensory conflicts. The most commonly studied sources of sensory data are visual and somatosensory information, particularly when processed under static conditions. There are no studies addressing sensory information manipulation on postural control during the performance of functional activities. Further studies addressing manipulation of new sources of sensory cues on postural control are required.

OBJECTIVE:The purpose of this study was to compare postural control in typically developing (TD) children and children with cerebral palsy (CP) during the sit-to-stand (STS) movement and to assess the relationship between static (during static standing position) and dynamic postural control (during STS movement) in both groups. METHOD:The center of pressure (CoP) behavior of 23 TD children and 6 children with spastic hemiplegic CP (Gross Motor Function Classification System [GMFCS] I and II) was assessed during STS movement performance and during static standing conditions with the use of a force plate. The data obtained from the force plate were used to calculate CoP variables: anteroposterior (AP) and mediolateral (ML) amplitudes of CoP displacement and the area and velocity of CoP oscillation. RESULTS:According to the Mann-Whitney test, children with CP exhibited higher CoP values in all of the analyzed variables during the beginning of STS movement. Pearson's correlation verified a positive correlation between the CoP variables during both static conditions and the performance of STS movement. CONCLUSIONS:Children with spastic hemiplegic CP present major postural oscillations during the beginning of STS movement compared with typical children. Moreover, the observed relationship between postural control in static and dynamic conditions reveals the importance of body control in the static position for the performance of functional activities that put the body in motion, such as STS movement.
