Spinal cord injury (SCI) not only leads to motor and sensory dysfunction, but just as debilitating are secondary consequences of SCI such as bowel disorders, neuroinflammation, immune suppression, pain and psychiatric disorders. In this thesis, I explore multiple aspects of recovery after SCI in...

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...

Physical training can affect the excitability of spinal reflexes in a training-specific manner in uninjured humans. Therefore, the first part of this thesis examined the changes in the excitability of a polysynaptic and a monosynaptic reflex in an ankle plantarflexor, after contrasting forms of...

Spinal cord injury (SCI) is an extremely debilitating condition, leading to sensory and motor dysfunction below the level of the injury. Presently, there are few effective treatments for SCI. This is in part due to the immense complexity of SCI pathophysiology. Thus, combined research approaches...

Walk Score® is a proprietary walkability metric that ranks locations by proximity to destinations, with emerging health promotion applications for increasing walking as physical activity. Currently, field validations of Walk Score® have only occurred in metropolitan regions of the United States;...

Highlights: Physical inactivity linked to chronic disease can be addressed by increasing walking. Understanding walkability can support health promotion policies and interventions. Walk Score® provides a uniquely accessible and generalizable metric for walkability. Walk Score® has been validated...

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 Injury
DownloadSpring 2013
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...

Neuronal Mechanisms of Hyperexcitability in Individuals with Spasticity after Spinal Cord Injury and Individuals with Bruxism
DownloadFall 2013
Motoneuron hyperexcitability is a characteristic of several different motor disorders. We examined neuronal mechanisms of hyperexcitability in two of these disorders: spasticity after spinal cord injury (SCI) and bruxism. Involuntary muscle spasms after SCI occur as a result of uncontrolled...
