Walking Speed, Gait Asymmetry, and Motor Variability
… the correlation between gait asymmetry and motor variability. Ten and fifty-one healthy control participants were recruited for aim 1 and aims 2/3, respectively. Reflective markers were placed on lower-extremity bony landmarks and participants walked on an instrumented treadmill while 3D …

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 …

Neural Dynamics in the Basal Ganglia Underlying Birdsong Practice and Performance
… How neurons encode and dynamically regulate motor variability across practice and performance states remains unknown. Songbirds sing more variable songs when practicing alone and highly stereotyped songs when performing to a female, providing a powerful system to explore how neural ensembles …

Influence of gender and obesity on motor performance, neuromuscular control and endurance in older adults
… obesity-related changes in performance and motor control as well as how they will be modified by gender, specifically among older adults, are still largely unexplored. As motor variability has recently been reported to be associated with fatigue development and may have the potential to …

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 …

INTEGRATION OF INTRA-AUDITORY MODALITIES FOR THE ENHANCEMENT OF MOTOR PERFORMANCE AND COORDINATION IN A CONSTANT FORCE PRODUCTION TASK
… feedback, and how the CNS adapts or learns a motor task using auditory feedback. The specific aims of this dissertation included: 1) development of analytical tools for the quantification of motor performance and coordination in a hierarchical structure of motor variability; 2) investigation …

Behavioral Monitoring to Identify Self-Injurious Behavior among Children with Autism Spectrum Disorder
… was implemented to consider such individual variability (Chapter 4). Both linear and nonlinear measures of motor variability were assessed as potential predictors in the model. Diverse classification methods were used (as in Chapter 3), and MLR outperformed other group level classifiers …

Neural Underpinnings of Walking Under Cognitive and Sensory Load: A Mobile Brain/Body Imaging Approach
… load in particular associated with reduced motor variability. Using an Independent Component Analysis (ICA) and dipole-fitting approach, neuro-oscillatory activity was then calculated from eight source-localized clusters of Independent Components (ICs). Significant modulations in average …

Shoulder pain and cycle to cycle kinematic spatial variability during recovery phase in manual wheelchair users
… examined intra-individual kinematic spatial variability during semi-circular wheelchair propulsion as a function of shoulder pain in MWU. Data from 10 experienced adult MWU with spinal cord injury (5 with shoulder pain; 5 without shoulder pain) was analyzed in this study. Participants …

Variability of peak shoulder force during wheelchair propulsion as a function of shoulder pain
… of shoulder pain. Growing evidence shows that variability in forces applied to biological tissue is related to musculoskeletal pain. The purpose of this study was to examine the variability of forces acting on the shoulder during wheelchair propulsion as a function of shoulder pain. Twenty-nine …

Neuromuscular Fatigue and Biomechanical Alterations during High-Intensity, Constant-Load Cycling
… movement pattern adjustments so as to use motor pathways that are less fatigued in an effort to maintain task performance; motor variability is thus increased. The primary purpose of the four studies contained within this doctoral thesis was to detail the progression of exercise-induced …

Structure of force as a predictor of oral motor learning in healthy younger and older adults
… and labial force structure to learning of oral motor continuous fine force tasks using a pursuit tracking paradigm. It investigated how error and the temporal and frequency structure of force during baseline performance predicted oral motor learning in healthy younger and older adults, drawing …
