Moss-Magee Rehabilitation Papers

Neuromotor dysfunction after a concussion is common, but balance tests used to assess neuromotor dysfunction are typically subjective. Current objective balance tests are either cost- or space-prohibitive, or utilize a static balance protocol, which may mask neuromotor dysfunction due to the simplicity of the task. To address this gap, our team developed an Android-based smartphone app (portable and cost-effective) that uses the sensors in the device (objective) to record movement profiles during a stepping-in-place task (dynamic movement). The purpose of this study was to examine the extent to which our custom smartphone app and protocol could discriminate neuromotor behavior between …

The Clinical Value Of Oculomotor Assessments Across The Continuum Of Concussion, Dillon Richards Nov 2022

The Clinical Value Of Oculomotor Assessments Across The Continuum Of Concussion, Dillon Richards

Electronic Thesis and Dissertation Repository

Concussions are complex conditions that are difficult to manage medically. Variations in symptom presentation, intricate neurophysiological processes, and the availability of a variety of possible assessment tools may contribute to this complexity. Clinicians must use a broad approach, employing both subjective symptom assessment and objective assessments to confirm a diagnosis and/or monitor progression and recovery. Oculomotor function after concussion may be an important indicator of injury, given the interconnectedness of oculomotor function, vestibulo-ocular and visual systems, and even cognition. Oculomotor function may be assessed objectively or indirectly using patient-reported symptom checklists as part of subjective assessments. One way of objectively …

Standing Weight Perception Across Unweighted Conditions In A Lower Body Positive Pressure Treadmill, Madison Rees, Matthew Ballesteros, Danielle Toth, Erik Lind, Bryanne N. Bellovary, James F. Hokanson

Transformations: Presentation Slides

Lower body positive pressure treadmills (LBPP-TM) provide assistive body weight support to the user by forcing air into an inflatable chamber in which the user is secured. The result of this positive pressure can be experienced as a lift to the user. The degree of chamber air pressure (CAP) determines the amount of supportive lift provided with greater and lesser CAP producing more and less lift, respectively. Exercise studies consistently report lower effort perceptions with greater CAP which suggest a reduced physiological and mechanical strain on the body. What is less well known is the effect on resting perceptions of …

The Effects Of Floatation-Rest On Cortisol Levels Of Patients With Glioblastoma Grade Iv: A Conceptual Framework, Hilario Gomez Apr 2022

The Effects Of Floatation-Rest On Cortisol Levels Of Patients With Glioblastoma Grade Iv: A Conceptual Framework, Hilario Gomez

Selected Honors Theses

Glioblastoma is reported to be the most aggressive and common brain tumor in adults (Davis, 2016). To help alleviate pain in patients with glioblastoma, floatation-REST (Restricted Environmental Stimulation Technique) is proposed. Such therapy has been shown to benefit chronic tension headaches, muscle tension, and other stress-related pain conditions (Feinstein, 2018). The magnesium and sulfate components of Epsom salt combined with controlled warm water allow the muscles and joints to relax. Studies show that magnesium targets the Adrenocorticotropic Hormone (ACTH) produced by the Anterior Pituitary Gland which in turn affects cortisol hormone levels to activate the body's immune defenses and eliminate …

Neurophysiological And Psychological Characteristics Of Individuals With History Of Lateral Ankle Sprain, Katherine Bain Jan 2022

Neurophysiological And Psychological Characteristics Of Individuals With History Of Lateral Ankle Sprain, Katherine Bain

Theses and Dissertations--Rehabilitation Sciences

Lateral ankle sprain (LAS) is among the most common lower limb musculoskeletal injuries impacting both the general and sport populations. Even more problematic is that approximately 70% of individuals who sustain an LAS develop residual deficits. Of that subgroup, roughly 40% develop chronic ankle instability (CAI). Chronic ankle instability is a clinical diagnosis defined by the presence of ongoing impairments following the initial LAS which may include perceived instability, pain, mechanical instability, and episodes of giving way during physical activity. Not all who sustain multiple ankle sprains or experience residual deficits fit the clinical diagnosis criteria for CAI; yet may …
