Walking is a locomotor task that integrates information from all over the nervous system. The lumbosacral spinal cord houses neural networks that contribute to locomotion. These networks dominate locomotor activity during development and may provide suitable targets for restoring function after...
The overall goal of this dissertation was to develop a novel rehabilitative intervention to improve walking after incomplete spinal cord injury (iSCI). It is widely known that arm movement modulates leg activity and improves the efficiency of gait. However, gait-specific rehabilitation...
Inhibitory feedback from sensory pathways is important for controlling movement. In this thesis we characterize a long-latency inhibitory spinal pathway to ankle flexors that is activated by low-threshold, homonymous afferents. In non-injured participants, this pathway was activated by both...
A pilot study investigating arm and leg FES-assisted cycling as an intervention for improving ambulation after Incomplete Spinal Cord InjuryDownload
People with incomplete spinal cord injury (iSCI) have the potential for recovering walking through plasticity-induced changes in the remaining neural circuitry. Current rehabilitation for walking attempts to induce such changes by providing relevant sensory inputs and motor commands through...
In this thesis the participation of tactile feedback from the hands in the control of balance was investigated. In Chapter 2, I characterized arm and leg reactions to unexpected perturbations delivered through the arms during walking. Perturbations applied at the hands resulted in early latency...
Middle-Aged and Older Adult Walking and Hiking Groups of Cochrane, Alberta: How Outdoor Group Exercise Influences Perceptions of Health, Healing, and DiseaseDownload
Middle-aged and older adult walking and hiking groups of Cochrane had unique perceptions of health and healing due to their activities, the equipment they used, the environments they explored, and the relationships they developed. Past anthropological research has focused on aging, ethnomedicine,...
Walking adaptation, training and assessment in young children and individuals with incomplete spinal cord injuryDownload
This thesis includes four projects that examine motor learning and assess novel approaches for the training and evaluation of walking. In Project 1 we study motor adaptation in children aged 8-36 months using a split-belt treadmill. Split-belt walking, in which one leg moves faster than the...
Functional electrical stimulation (FES) is a rehabilitative technology that can be used to improve walking in individuals with mobility impairments due to neurologic injury or disease. Feedback is essential for efficient FES-assisted walking. The overall goal of my project was to investigate...
Maintaining balance is controlled by two different processes: feedforward and feedback control. Feed-forward control is used prior to performing voluntary movements whereas feedback control is used to correct for unexpected perturbations. Studies suggested that age-related changes in postural...
