Adaptation of Stepping Responses During Perturbed Walking in Neurologically Impaired Subject

Abstract

This work investigates adaptation of stepping responses when neurologically impaired subject is subjected to repeated perturbations while walking. Balance assessment robot in combination with treadmill (BAR-TM) and Optitrack camera were used to deliver well repeated perturbations and to track foot placement respectively. Results show that when neurologically impaired subject is repeatedly subjected to identical perturbations we may expect adaptation period at the beginning of session when gait parameters change before they settle. We could speculate that in order to evoke repeatable postural responses during balance training patients should be subjected to limited number of exercises that would allow them to surpass adaptation period and focus on repeating the movement after it stabilizes.
