“…Unlike adults, children have preserved plantar flexion strength and distal range of movement. A previous study from our laboratory with CMT children found correlation between balance and joint/ muscle deficits[ 58 , 59 ] It is possible that children have increased confidence ellipse area and velocity at the expense of residual triceps surae activity, something that could be investigated by correlating clinical, kinematic and electromyographic data in future studies. Healthy adults control stance by increasing the muscular activity of the triceps surae, when under sensory deprivation on the soles of the feet[ 60 ] which could be correlated to children, at the early stages of neuropathic diseases.…”

Charcot Marie Tooth disease (CMT) has negative functional impact on postural control of children; however, it has not been widely studied. Stabilometry can provide insights about postural control and guide preventive interventions in immature perceptual and musculoskeletal systems as those seen in children with CMT. This cross-sectional study aimed to identify and interpret stabilometric variables that reflect the postural control of children with CMT. 53 subjects (age 6–17) were assigned to one of the two groups: CMT (15 males and 14 females with CMT) or Control (13 males and 11 females healthy). Quiet standing was tested in different conditions: with open and closed eyes on regular surface (open-regular, closed-regular) and foam surface (open-foam, closed-foam) using a force platform. The minimum of 2 and maximum of 3 trials of 30 seconds for each test condition provided the classical stabilometric variables and Romberg Quotient (RQv). CMT group showed increase of confidence ellipse area, mean velocity, mediolateral and anteroposterior velocities associated with decreased mean body oscillation frequency, as the complexity of tasks increased. CMT postural deficit was identified by greater and faster sway associated with these lower frequencies, when compared to Control.
