Error signals driving locomotor adaptation: cutaneous feedback from the foot is used to adapt movement during perturbed walking

摘要

Key points class="unordered" style="list-style-type:disc" id="tjp7343-list-0001">Sensory input from peripheral receptors are important for the regulation of walking patterns.Cutaneous input mediates muscle responses to deal with immediate external perturbations.In this study we focused on the role of cutaneous feedback in locomotor adaptation that takes place over minutes of training.We show that interfering with cutaneous feedback reduced adaptation to ankle perturbations during walking.These results help us understand the neural mechanisms underlying walking adaptation, and have clinical implications for treating walking impairments after neurological injuries.
