Breaking Barriers And Building Confidence: Interprofessional Education's Impact On Allied Health Students' Competence And Self-Efficacy In Addressing Exercise Accessibility For People With Disabilities, Elizabeth A. Starns, Rebecca Wehler, Lindsay A. Church, Stephanie Kubiak

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

Purpose: The researchers’ objective was to evaluate the effectiveness of an interprofessional educational (IPE) program on student learning while addressing exercise accessibility barriers experienced by people living with disabilities (PLWD), including allied health professionals’ lack of practical experience, knowledge, and perceived competence and comfort working with PLWD in a fitness setting. Method: A qualitative explanatory single case study approach utilizing individual interviews was used. The individual interviews that explored how a collaboration between allied health students influenced learning, perceived comfort, and perceived competence working with PLWD were audio-recorded, transcribed verbatim and thematically analyzed. Results: Four major themes emerged: collaboration, comfort, …

Acute Ingestion Of Dark Chocolate Fails To Affect Running Economy In Recreational Female Runners, Bianca J. De Lucia, Beau Kjerulf Greer, Christopher B. Taber

Topics in Exercise Science and Kinesiology

Topics in Exercise Science and Kinesiology Volume 5: Issue 1, Article 1, 2024. Ingestion of dark chocolate (DC), a dietary source high in flavanols, may increase nitric oxide bioavailability. Elevating blood nitric oxide concentrations may augment metabolic efficiency by reducing the amount of oxygen or energy needed to perform a given task. Utilizing a crossover design, the purpose of this study was to investigate the effect of acute ingestion of DC on running economy (RE). Nineteen recreationally trained females (age: 20±1 years) volunteered for this investigation, with 16 completing all procedures (n = 16). Two-hours before RE assessment, participants consumed …

Human System Composite Performance Measures: General Systems Performance Theory Insights, Lawrence Disalvi

Bioengineering Dissertations - Archive

Composite Performance Measures (CPMs) of human performance are widely employed in applications that range from mundane to life-changing, yet they are frequently presented without explanation or reference to theoretical underpinnings. The conceptual soundness of a widely used CPM approach, based on additive combination of constituent components, has been called into question by Kondraske. He argues the relevance of General Systems Performance Theory (GSPT) and performance capacity envelope concepts when applied to multidimensional CPM measures.

To obtain evidence-based answers to assertions regarding CPM types and rationale employed in medical and non-medical contexts, a Systematic Descriptive Review was conducted. Separately, the GSPT-based …

Ingestion of dark chocolate (DC), a dietary source high in flavanols, may increase nitric oxide bioavailability. Elevating blood nitric oxide concentrations may augment metabolic efficiency by reducing the amount of oxygen or energy needed to perform a given task. Utilizing a crossover design, the purpose of this study was to investigate the effect of acute ingestion of DC on running economy (RE). Nineteen recreationally trained females (age: 20±1 years) volunteered for this investigation, with 16 completing all procedures (n = 16). Two-hours before RE assessment, participants consumed either 42.5 g of DC or an isocaloric amount of white chocolate (WC) …

Mimicking An Asymmetrically Walking Visual Cue Alters Gait Symmetry In Healthy Adults, Krista G. Clark, Louisa D. Raisbeck, Scott E. Ross, Christopher K. Rhea

Rehabilitation Sciences Faculty Publications

Gait asymmetries are a common problem in clinical populations, such as those with a history of stroke or Parkinson’s disease. The use of a split-belt treadmill is one way to enhance gait symmetry but relies on specialty (and typically expensive) equipment. Alternatively, visual cues have been shown as a method to alter gait mechanics, but their utility in altering gait symmetry has been relatively understudied. Before deploying this method to clinical populations, a proof-of-concept study is needed to explore using visual cues to alter gait symmetry in healthy adults. Therefore, the purpose of this study was to examine the extent …

Using A Reverse Visually Guided Reaching Task To Distinguish Between Healthy Aging And Early Alzheimer’S Disease, Brandon Woolman

Dissertations, Master's Theses and Master's Reports

Changes in motor behavior may function as a proxy for cognitive decline. While Alzheimer's disease (AD) is associated with impairments in learning and memory, recent studies suggest that subtle changes in motor task performance may reflect early cognitive changes. For example, the visuomotor rotation task that manipulates visual feedback about hand position during reaching movements, can be used to examine cognitive changes in aging populations. The current study used the reverse visually guided reaching task (rVGR) which rotates visual feedback of participant’s hand position 180⁰ relative to the actual hand position. We sought to expand on previous literature by recruiting …

Developing A Methodology For Evaluating Postural Control And Functional Ability In Children With Cerebral Palsy, Abigail Schoppa

Honors College Theses

Background: Cerebral Palsy (CP) is a non-progressive group of disorders that interferes with postural control and gross motor function (GMF). The purpose of this study was to develop a methodology to evaluate and link postural control and functional ability by identifying the best measures to use.

Methods: For this study, children between the ages of 12 and 22 who have CP and a Gross Motor Function Classification System level I to III were recruited. They performed a series of gross motor tests from the BOT-2 while standing on a force plate to record their center of pressure (COP) movement. Several …

Modulation Of Persistent Inward Currents With Changes In Posture And Cutaneous Sensory Input, Ryan William Weller

Theses and Dissertations (Comprehensive)

Spinal motor neuron (MN) persistent inward currents (PIC) increase and sustain the MN output. PIC is amplified by descending monoamines and reduced by afferent inhibition. There is strong coupling between plantar cutaneous sensory input and lower limb MNs. Given that monoaminergic drive is altered with postures and motor tasks, our purpose was to assess posture-dependent plantar cutaneous sensory modulation of tibialis anterior (TA) MNs. We hypothesize that: 1) a supine position will suppress PIC, 2) removing the load from the bottom of the heel will inflate PIC, and 3) cutaneous stimulation of the plantar aspect of the heel will reduce …
