Cortical Oscillations During A Lateral Balance Perturbation While Walking, Joseph Lee
Cortical Oscillations During A Lateral Balance Perturbation While Walking, Joseph Lee
Dissertations (1934 -)
The role of sensory systems in the cortical control of dynamic balance was examined using electroencephalography (EEG) recordings during balance perturbations while walking. Specifically, we examined the impact of sensory deficits on cortical oscillations using vibratory stimuli to suppress sensory feedback and by comparing cortical oscillations during balance perturbations while walking in people with sensory deficits associated with cervical myelopathy and neurologically intact controls. Balance during walking provides a rich framework for investigating cortical control using EEG during a functionally relevant task. While this approach is promising, substantial technical challenges remain in recording and processing EEG in the noisy, artifact …
Dynamic Balance Control During Treadmill Walking In Chronic Stroke Survivors, Eric Richard Walker
Dynamic Balance Control During Treadmill Walking In Chronic Stroke Survivors, Eric Richard Walker
Dissertations (1934 -)
Maintaining dynamic balance is an important component of walking function that is likely impaired in chronic stroke survivors, evidenced by an increased prevalence of falls. Dynamic balance control requires maintaining the center of mass (COM) within the base of support during movement. During walking, dynamic balance control is achieved largely by modifying foot placement to adjust the base of support. However, chronic stroke survivors have difficulty with both precision control of foot placement, as well as reduced control of COM movement. The objective of this dissertation was to characterize dynamic balance control strategies during walking in chronic stroke survivors. Additionally, …
Mechanisms Of Sensorimotor Impairment In Multiple Sclerosis, Matthew Cheeming Chua
Mechanisms Of Sensorimotor Impairment In Multiple Sclerosis, Matthew Cheeming Chua
Dissertations (1934 -)
Sensorimotor impairments in people with multiple sclerosis (MS) might alter coordination and balance strategy during functional movements. People with MS often have symptoms such as weakness and discoordination in the lower limbs, resulting in poor walking and balance function. This decrease in function can result in falls, decreased community activity, unemployment, and reduced quality of life. As MS is a progressive disease resulting in a range of dysfunction, the amount of lower limb impairment can cause changes to walking and balance strategies to maintain functional performance. The overall objective of this dissertation was to quantify the impairment at the hip …
