VT=voluntary tracking (accuracy in following tracking the target signal); CMI=calf modulation index (coactivation during active movement) ;TAMI=tibialis anterior modulation index (the ability to activate the anterior tibial muscles during ankle dorsiflexion); TQ=torque (peak resistance measured during passive ankle dorsiflexion); SI=stretch index (response of the calf muscles to passive stretching). Significant values are shown in bold.
