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 …

Evaluation Of The Effectiveness Of A Pain Neuroscience Education Curriculum For Patients Who Experience Chronic Musculoskeletal Pain With Concurrent Opioid Dependence, Nicole D. Windsor

Theses and Dissertations--Rehabilitation Sciences

Background: Chronic musculoskeletal pain (CMP) is estimated to affect over 100 million adults annually and is targeted as an instigator of opioid dependence (OpD). Opioid medications are often the first response for patients suffering from CMP, but over 10 million people annually admit to misusing opioids. With the opioid epidemic, the healthcare system now has a population of patients who experience CMP with concurrent OpD. This persistent problem creates a perfect storm of fear of movement, low self-efficacy, and physical dysfunction. A critical component to chronic pain management is understanding how patients view their pain experience. Education may be one …

The Influence Of Physical Health, Emotional Health, And Socioeconomic Factors On The Musculoskeletal Pain Experience In Patients Attending A Pro Bono Physical Therapy Clinic, Garrett Naze

Theses and Dissertations--Rehabilitation Sciences

Non-communicable, chronic diseases are highly prevalent in the United States, reducing the quality of life for those affected and contributing to the majority of the nation’s healthcare expenditure. These conditions include, among others, cardiovascular disease, diabetes, and musculoskeletal disease. Musculoskeletal disease is particularly of interest for the field of physical therapy as the vast majority of patients seeking care in the outpatient setting present with musculoskeletal pain complaints, resulting in limitations in function, participation, and quality of life for the patient.

The factors influencing health outcomes are diverse and include a person’s physical environment, social and economic factors, access to …

Clinical And Neurophysiological Effects Of Dry Needling On Individuals With Chronic Ankle Instability, Jennifer Mullins

Theses and Dissertations--Rehabilitation Sciences

Ankle sprains are generally considered innocuous injuries; however, as many as 74% of patients will develop chronic symptoms. 1-3 Chronic ankle instability (CAI) is defined by a history of ankle sprain accompanied by ongoing bouts of giving way, residual ankle sprain symptoms, and a decrease in patient-perceived function. As understanding of sensorimotor deficits in individuals with CAI have advanced, treatment strategies have evolved to include a robust focus on balance training to mitigate dynamic and static postural control impairments exhibited in individuals with CAI. A problem arises as these improvements have not been conclusively linked to a decrease in CAI. …

Influences Of Functional And Psychological Factors On Biomechanics Following An Anterior Cruciate Ligament (Acl) Reconstruction, Chelsey Roe

Theses and Dissertations--Rehabilitation Sciences

Objective: The aims of this research were to identify gaps in the literature related to return to sport (RTS) test batteries following primary anterior cruciate ligament reconstruction (ACLR) (Aim 1) and define recovery in athletes from 4-9 months after ACLR across three domains: 1) psychological recovery and biomechanics (Aim 2), 2) rehabilitation quantity and biomechanics (Aim 3), and 3) functional performance and biomechanics (Aim 4). Ultimately, the results of this research would quantify recovery following ACLR in athletes with a desire to RTS and identify objective criteria throughout rehabilitation prior to RTS.

Participants: Twenty-two post-ACLR athletes 17 females, 8 males, …

Clinical Measurements Of The Posterior Shoulder Endurance Test (Pset), Neil A. Evans

Theses and Dissertations--Rehabilitation Sciences

Of the intrinsic factors responsible for non-traumatic shoulder pain, muscular endurance is often not measured by rehabilitation professionals due to the lack of available shoulder endurance measures. Measurement properties of the PSET have not been adequately assessed in previous studies. The purpose of this dissertation was to develop the clinical measurement properties of the Posterior Shoulder Endurance Test (PSET) so that it might be used as a clinical measure of shoulder muscular endurance.

Electromyography (EMG) offers the ability to identify which muscles in the posterior shoulder girdle are fatiguing during the PSET. Surface EMG of upper trapezius (UT), middle trapezius …

A Brain-Computer Interface For Closed-Loop Sensory Stimulation During Motor Training In Patients With Tetraplegia, Sarah Helen Thomas

Theses and Dissertations--Biomedical Engineering

Normal movement execution requires proper coupling of motor and sensory activation. An increasing body of literature supports the idea that incorporation of sensory stimulation into motor rehabilitation practices increases its effectiveness. Paired associative stimulation (PAS) studies, in which afferent and efferent pathways are activated in tandem, have brought attention to the importance of well-timed stimulation rather than non-associative (i.e., open-loop) activation. In patients with tetraplegia resulting from spinal cord injury (SCI), varying degrees of upper limb function may remain and could be harnessed for rehabilitation. Incorporating associative sensory stimulation coupled with self-paced motor training would be a means for supplementing …

Changes In Muscle Size, Quality And Power Are Related To Physical Function In Patients With Critical Illness, Kirby Mayer

Theses and Dissertations--Rehabilitation Sciences

Patients admitted to intensive care unit (ICU) are known to develop significant impairments in physical function. Patients with critical illness suffer up to 30% reductions in muscle size within the first ten days of admission to the ICU. Muscle strength testing, Medical Research Council-sum score, is current gold-standard to diagnosis ICU-acquired weakness and predicts risk of mortality and long-term physical function. Muscle power different from muscle strength in that it accounts for velocity of movement, is potentially a better independent predictor of function that has not been studied in this population. In addition, we hypothesize that muscle size and quality …

Design And Analysis Of A 3d-Printed, Thermoplastic Elastomer (Tpe) Spring Element For Use In Corrective Hand Orthotics, Kevin Thomas Richardson

Theses and Dissertations--Mechanical Engineering

This thesis proposes an algorithm that determine the geometry of 3D-printed, custom-designed spring element bands made of thermoplastic elastomer (TPE) for use in a wearable orthotic device to aid in the physical therapy of a human hand exhibiting spasticity after stroke. Each finger of the hand is modeled as a mechanical system consisting of a triple-rod pendulum with nonlinear stiffness at each joint and forces applied at the attachment point of each flexor muscle. The system is assumed quasi-static, which leads to a torque balance between the flexor tendons in the hand, joint stiffness and the design force applied to …

Muscle Synergy During A Single Leg Standing Test In Ambulatory Children With Cerebral Palsy, Brennan L. Smith

Theses and Dissertations--Kinesiology and Health Promotion

INTRODUCTION: Cerebral Palsy (CP) is a sensorimotor disorder characterized by dysfunctional motor coordination, balance problems, and loss of selective motor control. Motor coordination exhibited as co-contraction, has been subjectively quantified using gait analysis, but recent studies have begun to objectively analyze the amount of co-contraction by collecting electromyography (EMG) data. Center of pressure excursion (COPE) measurements collected during a single leg standing test (SLST) have shown to be more valid measurements of balance in populations with motor disabilities than a SLST alone. A recent study has correlated increased COPE velocity with a lower fall risk as determined by reported fall …

Longitudinal Adaptations In Muscle Strength, Functional Performance, Gait Biomechanics, And Patient-Reported Function After Unilateral Total Knee Arthroplasty, Paul W. Kline

Theses and Dissertations--Rehabilitation Sciences

Objective: The aims of this research were to identify gaps in the literature related to impairments after total knee arthroplasty (TKA) (Aim 1) and define recovery between 3 and 6 months after TKA across four domains: 1) hip and knee muscle performance, 2) functional performance, 3) patient-reported function, and 4) biomechanics of walking and stair descent (Aim 2). Additionally, this project sought to explore the relationships between each domain (Aim 3) and establish predictive models to allow clinicians to use clinical measures to predict future gait biomechanics in patients after TKA (Aim 4). Ultimately, the results of this research would …

A Comparison Of Upper Extremity Function Between Female Breast Cancer Survivors And Healthy Controls: Typical Self- Report Of Function, Motion, Strength And Muscular Endurance, Mary Insana Fisher

Theses and Dissertations--Rehabilitation Sciences

Many women who have experienced breast cancer (BC) report continued impairments in upper extremity (UE) function beyond the time required for normal healing after surgical treatment. Most research supporting this has not made comparisons between survivors of breast cancer (BCS) to a sample of healthy women. This lack of comparison to a healthy cohort prevents an understanding of whether continued deficits in UE function are due to normal aging or the BC treatment.

The purpose of this research was to compare quality of life (QOL) and UE function among long term breast cancer survivors and similar aged women without cancer. …

Effect Of Lower Body Positive Pressure On Cardiovascular Response At Various Degrees Of Head Up Tilt, Vladimir Ilyich Kostas

Theses and Dissertations--Kinesiology and Health Promotion

Various models of simulated weightlessness and resulting cardiovascular effects have been researched in the last 50 years of space exploration. Examples of such models are the Alter-G (Alt-G) treadmill used for body unweighting and head-up-tilt (HUT) model each providing similar cardiovascular effects, but differing in their stimulation of vestibular centers . Advantages of using the Alt-G include: use of lower body positive pressure (LBPP) to simulate hypogravity, it acts as a countermeasure to alleviate negative cardiovascular effects of standing and provides a constant vestibular stimulus. In addition, the Alt-G shorts themselves may be providing a certain degree of LBPP, acting …
