Lower Body Joint Moments During The Golf Swing In Older Adults: Comparison To Other Activities Of Daily Living, Scott K. Lynn, Junsig Wang, Abigail C. Schmitt, C. Lowry Barnes

Health, Human Performance and Recreation Faculty Publications and Presentations

Golf participation has increased dramatically in the last several years. With this increase in participation, clinicians need better evidenced based strategies to advise those golfers with different pathologies when it is safe to return to the game. Golf teaching professionals also need to understand how to alter golf mechanics to protect injured and/or diseased joints in golfers to allow them to play pain free and avoid further injury. This study used a 3-dimensional link segment model to calculate the net joint moments on the large lower limb joints (knee and hip) during golf (lead and trail leg) and two commonly …

Quantifying Balance: Computational And Learning Frameworks For The Characterization Of Balance In Bipedal Systems, Kubra Akbas

Dissertations

In clinical practice and general healthcare settings, the lack of reliable and objective balance and stability assessment metrics hinders the tracking of patient performance progression during rehabilitation; the assessment of bipedal balance plays a crucial role in understanding stability and falls in humans and other bipeds, while providing clinicians important information regarding rehabilitation outcomes. Bipedal balance has often been examined through kinematic or kinetic quantities, such as the Zero Moment Point and Center of Pressure; however, analyzing balance specifically through the body's Center of Mass (COM) state offers a holistic and easily comprehensible view of balance and stability.

Temporal Organization Of Stride-To-Stride Variations Contradicts Predictive Models For Sensorimotor Control Of Footfalls During Walking, Madhur Mangalam, Damian G. Kelty-Stephen, Joel H. Sommerfeld, Nicholas Stergiou, Aaron Likens

Journal Articles

Walking exhibits stride-to-stride variations. Given ongoing perturbations, these variations critically support continuous adaptations between the goal-directed organism and its surroundings. Here, we report that stride-to-stride variations during self-paced overground walking show cascade-like intermittency—stride intervals become uneven because stride intervals of different sizes interact and do not simply balance each other. Moreover, even when synchronizing footfalls with visual cues with variable timing of presentation, asynchrony in the timings of the cue and footfall shows cascade-like intermittency. This evidence conflicts with theories about the sensorimotor control of walking, according to which internal predictive models correct asynchrony in the timings of the cue …

The Influence Of Concussion History And Head Acceleration On Lower Extremity Function, Warren Forbes

UNLV Theses, Dissertations, Professional Papers, and Capstones

Sport-related concussions (SRCs) play a very debilitative role in athletics with between 1.7 – 3 million SRCs occurring annually (Clay et al., 2013; Zuckerman et al., 2015). This equates to upwards of 21.5 SRCs per 1000 athletic exposures. Research pertaining to SRC has received intense focus because of the substantial financial impact on the US healthcare system as well as the negative impact that SRCs have on the quality of life of athletes. Much of the research concerning SRC has been centered around management and ensuring adequate recovery from SRC-related symptoms. The current return to play (RTP) criteria from an …

Age-Related Differences In Motor Performance, Jessica Anne Prebor

Rehabilitation Sciences Theses & Dissertations

The purpose of this work was to study the age effects on average performance and variability of movement responses in children, young adults, and older adults across multiple motor tasks. Optimal motor performance is observed in healthy young adults with declines observed at either end of the lifespan. This pattern has been represented as a U-shaped/inverted U-shaped curve. Little is known about if this pattern persists in chewing dynamics. While chewing has been found to improve aspects of attention, a cognitive function, research is limited on the relationship between chewing and other motor tasks.

A Dynamical Systems Approach To Characterizing Brain–Body Interactions During Movement: Challenges, Interpretations, And Recommendations, Derek C. Monroe, Nathaniel T. Berry, Peter C. Fino, Christopher K. Rhea

Rehabilitation Sciences Faculty Publications

Brain–body interactions (BBIs) have been the focus of intense scrutiny since the inception of the scientific method, playing a foundational role in the earliest debates over the philosophy of science. Contemporary investigations of BBIs to elucidate the neural principles of motor control have benefited from advances in neuroimaging, device engineering, and signal processing. However, these studies generally suffer from two major limitations. First, they rely on interpretations of ‘brain’ activity that are behavioral in nature, rather than neuroanatomical or biophysical. Second, they employ methodological approaches that are inconsistent with a dynamical systems approach to neuromotor control. These limitations represent a …

Evaluating The Accuracy Of Inertial Measurment Units In Detecting Gait Parameters For Lower Limb Prosthesis And Orthosis Users, Bryce Fuller

USF Tampa Graduate Theses and Dissertations

A Gait Extraction System (GES) was developed to investigate the accuracy of wearable sensors by producing gait parameters, to be compared against a gold standard motion capture system. Two inertial measurement units (IMUs) were placed in the lower limb region, specifically in the shank region of each leg. The GES uses algorithms to extract the gait cycle from raw acceleration data to produce gait parameters such as stride length, stride time, step length, step time, stance time, swing time and cadence. There were three main trials that consisted solely of a flat road, a road with small hills and a …

Novel Approach For Non-Invasive Prediction Of Body Shape And Habitus, Emma Young

Electronic Theses and Dissertations

While marker-based motion capture remains the gold standard in measuring human movement, accuracy is influenced by soft-tissue artifacts, particularly for subjects with high body mass index (BMI) where markers are not placed close to the underlying bone. Obesity influences joint loads and motion patterns, and BMI may not be sufficient to capture the distribution of a subject’s weight or to differentiate differences between subjects. Subjects in need of a joint replacement are more likely to have mobility issues or pain, which prevents exercise. Obesity also increases the likelihood of needing a total joint replacement. Accurate movement data for subjects with …

Biomechanical And Psychophysical Underpinnings Of Balance Dysfunction In Individuals With Traumatic Brain Injury, Naphtaly Ehrenberg

Dissertations

Falls are a major burden on healthcare infrastructure, especially in older adults and even more so in older individuals that are living in institutions. According to data from the Centers for Disease Control and Prevention (CDC), from 2010 to 2020, unintentional falls were the leading cause of nonfatal emergency department visits for all age groups except among individuals from 15-24 years of age, where unintentional falls ranked a very close second to being unintentionally struck by or against. Among older individuals living in the community, approximately 30-35% fall at least once in a given year, and around three times as …

Coordination Rigidity In The Gait, Posture, And Speech Of Persons With Parkinson’S Disease, Dobromir Dotov, Valérie Cochen De Cock, Valérie Driss, Benoît Brady, Simone Dalla Bella

Journal Articles

Parkinson’s disease (PD) is associated with reduced coordination abilities. These can result either in random or rigid patterns of movement. The latter, described here as coordination rigidity (CR), have been studied less often. We explored whether CR was present in gait, quiet stance, and speech—tasks involving coordination among multiple joints and muscles. Kinematic and voice recordings were used to compute measures describing the dynamics of systems with multiple degrees of freedom and nonlinear interactions. After clinical evaluation, patients with moderate stage PD were compared against matched healthy participants. In the PD group, gait dynamics was associated with decreased dynamic divergence—lower …
