The relationship between working memory and gait performance 2013 1319 The purpose of this study was to establish how performance in cognitive (i.e., working memory) and motor (i.e., gait) tasks vary when the tasks are performed in isolation and concurrently. Sixteen collegiate students, three males and 13 females, comp...
Gait and balance characteristics after a non-cerebellar stroke 2014 975 One of the most common neurological injuries in the elderly is a stroke event, affecting nearly 800,000 adults in the U.S. alone every year. Since falls occur at a rate of 73% per year with people who are more than six months past the stroke event co...
Dosage effect on neuromuscular retention of a fractal gait pattern using a visual stimulus 2016 389 Our view of certain gait disorders has changed with the development of new interventions for gait training. Recent gait research has suggested that humans do not walk with metronomic patterns, but with fractal patterns. Fractal patterns which are a c...
Virtual obstacle crossing and the clinical implications for rehabilitation 2016 288 Fall risk is a concern for a variety of clinical populations, especially in lower-limb amputees. The risk of falling during walking is increased by an individual with pathology’s diminished ability for obstacle negotiation. Virtual obstacle crossing ...
Using feedback enhanced visual metronomes to manipulate gait dynamics 2016 275 Recent literature suggests that gait dynamics plays a role in establishing healthy, adaptive gait behavior, and that illness or injury can alter the dynamic patterns of gait (termed fractal patterns). So called “dynamical diseases” change the fractal...
Characteristics and coupling of cardiac and locomotor rhythms during treadmill walking tasks 2016 715 Studying the variability of physiological subsystems (e.g., cardiac and locomotor control systems) has been insightful in understanding how functional and dysfunctional patterns emerge within their behaviors. The coupling of these subsystems (termed ...
Postural control differences among collision, contact, and non-contact sport female athletes 2017 209 Postural control is defined as the act of maintaining balance, which is a foundational skill in nearly every sport. Postural control can be enhanced with practice or degraded following a neurological insult. Since balance tests are a standard practic...
Changes in Lower Extremity Biomechanics as a Result of Feedback in Virtual Obstacle Crossing 2018 89 The purpose of this study was to examine changes in lower extremity joint angles of the ankle, knee, and hip as a result of virtual reality obstacle crossing technology and feedback within the virtual environment. Virtual reality obstacle crossing tr...
An investigation into the relationship between locomotor dynamics and adaptability 2018 72 Over the last 40 years, a new paradigm has been posited where the variability observed in physiological systems is a consequence of the interactions occurring between the various components that affect the system. While quantifying the magnitude of v...
Effect of fatigue on postural control 2018 112 Postural control is a complex and dynamic process that is further complicated by ever changing individual characteristics and environmental factors. For example, even when attempting the simple task of standing still, the postural control system must...
