Kinematics and postural muscular activity during continuous oscillating platform movement in children and adolescents with cerebral palsy

Appropriate use of postural control strategies is required to stabilize balance and prevent falls. Typically, when faced with a small perturbation, balance is maintained through modulation of joint torques about the ankle. If a postural disturbance is larger, the center of mass must be kept within the confines of the base of support using larger movements about the hip. A large enough perturbation may require a step to avoid falling [1]. Having knowledge or previous experience of an upcoming perturbation, allows preparation for the postural disturbance by using anticipatory postural mechanisms [2 –4].
