Adaptation and vision change the relationship between muscle activity of the lower limbs and body movement during human balance perturbations.
OBJECTIVE: Investigate the relationship between changes in lower limb EMG root mean square (RMS) activity and changes in body movement during perturbed standing. Specifically, linear movement variance, torque variance and body posture were correlated against tibialis anterior and gastrocnemius RMS EMG activity during perturbed standing by vibration of the calf muscles. METHODS: Eighteen healthy pa
