Gait and balance characteristics after a non-cerebellar stroke 2014 1197 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...
Virtual obstacle crossing and the clinical implications for rehabilitation 2016 527 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 412 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...
The relationship between working memory and gait performance 2013 1552 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...
Characteristics and coupling of cardiac and locomotor rhythms during treadmill walking tasks 2016 1014 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 ...
Effect of fatigue on postural control 2018 610 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...
Training functional mobility using a dynamic virtual reality obstacle course 2020 100 Falling poses a significant risk of injury for older adults, thus decreasing quality of life. Major risk factors for falling include decrements in gait and balance, and adverse patient-reported health and well-being. Virtual Reality (VR) can be a cos...
Dosage effect on neuromuscular retention of a fractal gait pattern using a visual stimulus 2016 603 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...
Changes in Lower Extremity Biomechanics as a Result of Feedback in Virtual Obstacle Crossing 2018 208 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...
Postural control differences among collision, contact, and non-contact sport female athletes 2017 380 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...
An investigation into the relationship between locomotor dynamics and adaptability 2018 276 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...
Implementing OPTIMAL Theory in lower extremity tasks to reduce risk of injury 2021 12 Anterior cruciate ligament (ACL) injury affects roughly 150,000 people each year, and the majority of those affected are women and girls. Major risk factors for sustaining an ACL injury are condensed into the following categories: (1) anatomical/stru...
Long-term retention of patient-reported outcomes after a 12-week attentional focus balance training program 2021 9 Older adults are at a higher risk of falls due to physiological and psychological factors associated with natural aging. Relative to balance, a recent meta-analysis showed that an external focus of attention results in enhanced learning of balance ta...
