The Role of Perturbed Auditory Information for Self-motion in Gait

As people walk and interact with objects such as when opening a door, their movements make sounds. It is possible that these sounds are also used as feedback to stabilize and adapt movement. There is some evidence for such a connection between the auditory and motor systems in activities of daily living, yet the empirical work is insufficient because the role of the auditory system in movement is a relatively neglected topic. The objective of this study is to address this gap. The study will also evaluate the potential for improvements in movement stability and variability by restricting or augmenting the auditory feedback from the participants' footstep sounds.
