Aging, Gait Variability, and Adaptability
… study the relationships between age, measures of gait variability, and locomotor adaptability. Measures of gait variability are used to identify maladapted locomotor behavior, motor disease, and risk of falls. The first aim was to determine the relationships between age and measures of gait …

Gait variability in persons with multiple sclerosis
… thesis contains three investigations examining gait variability in people with multiple sclerosis (MS), which is a neurological disease that can result in significant walking impairment. Gait variability, i.e. fluctuations in the mechanics and kinematics of steps during walking, has been …

Gait Variability for Predicting Individual Performance in Military-Relevant Tasks
… patterns is captured by the construct of motor variability (MV). MV is being used increasingly to describe movement quality and function among clinical populations and elderly individuals. However, current evidence presents conflicting views on whether increased MV offers benefits or is a …

Effect of Textured Insoles on Gait Variability During Continous Overground Walking in Older Adult Fallers and Non-Fallers
… in older adults. There is a need amongst gait clinicians and researchers to develop better methods to analyze fall risk. In addition to the calculation of mean spatiotemporal gait parameters, gait variability and the fractal scaling index (FSI) have been suggested to be sensitive markers …

Detecting Transient Changes in Gait Using Fractal Scaling of Gait Variability in Conjunction with Gaussian Continuous Wavelet Transform
… More recently, investigators have focused on gait complexity and the structure of spatiotemporal variations during walking and running. This study evaluated the use of time-series analyses to determine gait parameters during running. Subjects were college-age female soccer players. …

The Effect of Knee Osteoarthritis on the Variability and Fractal Dynamics of Human Gait
… adult population, and has a greater influence on gait compared to the effects of aging alone. Spatiotemporal parameters can be used to quantify age-related changes in gait, however gait variability (i.e., the magnitude of stride-to-stride fluctuations with respect to time) and the fractal-scaling …

Adaptability of Human Gait: Exploring Red Noise Auditory Stimuli and Gait Fluctuation Patterns
Using dynamical systems approaches to examine gait, it has been found that variability structure is important for understanding gait, and that stimuli can influence gait variability. The present study was performed to test for an adaptability limit and to analyze stepping strategies used for …

Monitoring Gait Complexity in the Wild
Human steady-state gait exhibits subtle stride-to-stride fluctuations that produce complex patterns, termed gait complexity, which provide information about the quality of gait control and adaptive capacity of the walker. Our knowledge of gait complexity is premised on studies estimating nonlinear …

The Influence of the Initiation of a Graded Exercise Protocol on Dynamic Postural Stability Following a Concussion
… deteriorates with moderate intensity exercise. Gait variability, defined as the fluctuation in gait characteristic between steps, is a sensitive measure of postural stability in populations with higher level gait disorders. Objective: The purpose of this study was to examine the influence of a …

Influence of Vibratory Plantar Stimulation on Cortical Motor Planning and Spatiotemporal Step Parameters
… input for anticipatory postural adjustments and gait initiation. Although previous literature suggests that plantar vibratory stimulation can improve balance and reduce gait variability, its influence on cortical motor planning remains unclear. This study examined whether augmenting plantar …

The use of inertial measurement units for the determination of gait spatio-temporal parameters
… could be used to obtain accurate and objective gait parameters within typical developed adults (TDA) and Parkinson’s disease (PD). The thesis comprised four studies, the first establishing the validity of the IMU method when measuring the vertical centre of mass (CoM) acceleration, velocity and …

The validity of an accelerometer-based activity monitoring system and the consistency of locomotive activity of community-living older adults
… frequency (cycles/second) to identify overground gait and pedaling. These studies evaluate the validity of this system in a real-life environment and then investigate people's locomotive behavior across weekdays of the same week. METHODS: Wearing the monitoring system developed at BU on their …

Applications of Motor Variability for Assessing Repetitive Occupational Tasks
… variations exist in human movement, called motor variability (MV). Current evidence suggests that MV can be beneficial, and that there is an inverse association between MV and risk of injury. To better understand how the CNS manipulates MV to reduce injury risks, we investigated the effects of …

Assessing the Effects of Exoskeleton Use on Balance and Postural Stability
… on level walking, BSE use caused an increase in gait step width and gait variability, and decrease in the margin of stability. BSE use with high supportive torque led to adapted gait patterns in early-stance phase. Hip range of motion and peak hip flexion velocity also decreased, and participants …
