The relationship between working memory and gait performance 2013 1613 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 1351 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 655 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 590 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 ...
Postural control differences among collision, contact, and non-contact sport female athletes 2017 444 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 342 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...
Training functional mobility using a dynamic virtual reality obstacle course 2020 179 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...
Implementing OPTIMAL Theory in lower extremity tasks to reduce risk of injury 2021 76 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 64 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...
Investigating the gap between evidence and practice in the use of virtual reality for physical rehabilitation – is VR just a fancy toy? 2021 44 Physical rehabilitation aims to address functional deficits, restore healthy movement patterns, and optimize independence following dysfunction caused by aging, injury, or disease. Virtual reality (VR) has been shown to be a promising tool to create ...
Using feedback enhanced visual metronomes to manipulate gait dynamics 2016 488 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 1102 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 ...
Changes in Lower Extremity Biomechanics as a Result of Feedback in Virtual Obstacle Crossing 2018 260 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...
Effect of fatigue on postural control 2018 684 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...
Examining changes in dynamic balance in older adults after balance training with attentional focus cues 2022 13 Functional balance in humans can be characterized as maintaining the center of mass (COM) within the base of support (BOS). When the COM moves outside the BOS, a fall can occur if there is not an immediate reaction to modify the BOS. The ability to d...
