Fall 2013
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...

Development of Surrogate Spinal Cords for the Evaluation of Electrode Arrays Used in Intraspinal Implants
DownloadSpring 2012
A surrogate spinal cord was developed to test the mechanical stability of electrode arrays for intraspinal implants. The mechanical and surface properties of candidate materials were tested. The elastic modulus was characterized using dynamic mechanical analysis. Forces required to indent the...

Walking adaptation, training and assessment in young children and individuals with incomplete spinal cord injury
DownloadFall 2010
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...

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...

Brainstem derived serotonin (5-HT) normally facilitates spinal motoneuron excitability and inhibits sensory afferent transmission and associated spinal reflexes. Because the 5-HT innervation of the spinal cord is almost exclusively derived from brainstem neurons, spinal cord injury leads to an...

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...

External sensors for the feedback control of functional electrical stimulation assisted walking
DownloadFall 2010
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...

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....

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...
