This thesis discusses the pathophysiological mechanisms underlying neuromotor impairments in people with spastic cerebral palsy (CP). Ninety percent of people with CP have spastic CP and 60% have bilateral motor impairments. The first two chapters introduce CP and review the mechanisms known to...

Middle-Aged and Older Adult Walking and Hiking Groups of Cochrane, Alberta: How Outdoor Group Exercise Influences Perceptions of Health, Healing, and Disease
DownloadFall 2011
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,...

MODELING INCOMPLETE CERVICAL SPINAL CORD INJURY IN RATS TO EXPLORE MECHANISMS OF REHABILITATIVE TRAINING
DownloadFall 2013
Although limited functional recovery is observed following spinal cord injury (SCI), the most successful approach to promote recovery to date has been rehabilitative training. However, the effects of training are not stunning. With a thorough understanding of the intracellular mechanisms involved...

Motor unit recruitment by intraspinal microstimulation and long-term neuromuscular adaptations
DownloadFall 2009
Spinal cord injury is a devastating neurological disorder partially characterized by a loss of motor function below the lesion. The dramatic loss of activity results in muscle atrophy and slow-to-fast transformation of contractile elements, producing smaller, weaker and more fatiguable muscles....

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...

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...

Peripheral and central contributions to evoked contractions during neuromuscular electrical stimulation
DownloadFall 2013
The present thesis examined two general questions regarding neuromuscular electrical stimulation (NMES): 1) How can the delivery of NMES be optimised to enhance synaptic motor unit recruitment via reflex pathways (central pathways) and 2) Can motor unit recruitment through central pathways...

This thesis explores strategies to promote neuronal plasticity in a rat model of cervical spinal cord injury (SCI) in an effort to achieve improved recovery of skilled forelimb use. I focused on investigating how motor pathways disrupted by an SCI may connect to spared, lesion-bridging relay...

Rehabilitative reaching training and plasticity following spinal cord injury in the adult rat
DownloadSpring 2011
Injury to the cervical spinal cord is a devastating event that results in a transient to permanent loss of sensory and motor functions following injury. Moderate recovery has been reported to occur in individuals and in animal models after spinal cord injury (SCI). One approach to promote...

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...
