Muscle Fatigue And Motor Output Variability With Acute Stress In Healthy Young Adults And Veterans With Posttraumatic Stress Disorder, Manda Linea Keller

Dissertations (1934 -)

Acute stress can alter motor performance differently for men and women. The first aim of this dissertation addresses possible causes for the sex difference in the motor response of a low-intensity fatiguing contraction of the elbow flexor muscles to an acute stressor (difficult mental math) in young, healthy adults. Muscle fatigue increased for men and women when exposed to the stressor, but impairment was more prominent for the women. This work showed that fatigue in the central nervous system, specifically in cortical motor and premotor areas, as well as relaxation rates of the muscle (quantified with cortical stimulation) were not …

Bilateral Oscillatory Hip Movements Induce Windup Of Multijoint Lower Extremity Spastic Reflexes In Chronic Spinal Cord Injury, Tanya Onushko, Allison S. Hyngstrom, Brian D. Schmit

Physical Therapy Faculty Research and Publications

After spinal cord injury (SCI), alterations in intrinsic motoneuron properties have been shown to be partly responsible for spastic reflex behaviors in human SCI. In particular, a dysregulation of voltage-dependent depolarizing persistent inward currents (PICs) may permit sustained muscle contraction after the removal of a brief excitatory stimulus. Windup, in which the motor response increases with repeated activation, is an indicator of PICs. Although windup of homonymous stretch reflexes has been shown, multijoint muscle activity is often observed following imposed limb movements and may exhibit a similar windup phenomenon. The purpose of this study was to identify and quantify windup …

Loma Linda University Electronic Theses, Dissertations & Projects

Balance control decreases in the elderly and currently 33 to 50 percent of people over 65 years of age experience a fall each year resulting in ten thousand deaths annually. Many balance‐training programs use expensive equipment and a clinical setting for the training. The need for reliable and low cost tools is essential for fall prevention and rehabilitation of the aging population. Virtual reality gaming is emerging as a solution for this problem. The purpose of the six week study was to determine the effects of virtual reality gaming, specifically the Nintendo Wii Fit Balance Board (WBB), on dynamic balance …

Athletic Training Students' Ability To Identify Scapular Dyskinesis, Priscilla M. Dwelly

Graduate Theses and Dissertations

Scapular dyskinesis refers to abnormal movement patterns of the scapula, which have been associated with injury. Previous investigations have validated the scapular dyskinesis test as a visual assessment method using physicians, physical therapists, and certified athletic trainers. Through educational programs, athletic training students should be taught what scapular dyskinesis is and how to identify it. Therefore, the purpose of this investigation was to (a) evaluate entry-level graduate athletic training students' ability to identify scapular dyskinesis, (b) assess their reliability, and (c) determine if they were able to correctly identify the muscles involved in rehabilitating an individual with scapular dyskinesis.

The Acute Effects Of Static Stretching Of The Gastrocnemius On Limits Of Stability In Young Adults Versus Elderly Adults, Matt Bugnet, Kirk Player

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background and Purpose: Balance is an important part of everyday life for all individuals with many body systems interacting to achieve optimal balance. Proprioceptive organs aid in this interaction, while also acting as stretch receptors. Therefore, it is possible that stretching may influence the overall balance of the individual. The purpose of this study was to investigate the acute effects of stretching on dynamic balance of healthy young and elderly adults. The two groups were used to determine if stretching may discriminately affect balance at different ages.

Subjects: Thirty healthy adults between the ages of 18 and 35 …

Effects Of Environment On Children's Motor Scores, Eligibility Status, And Administration Times, Derrick Mittelstadt, Abigail Parker, Kirsten Pickett, Heather Temkin

UNLV Theses, Dissertations, Professional Papers, and Capstones

Best practices for assessing developmental skills in young children focus on naturalistic observation in everyday settings, but the effects of environment on test scores, eligibility status and administration time have not been explored. The Peabody Developmental Motor Scales-Second Edition (PDMS-2) was administered to 34 children aged 18 to 59 months in natural and pull-out settings. PDMS-2 total, gross, and fine motor quotient (TMQ, GMQ, and FMQ) scores were significantly lower in the natural environment (p’s≤.014). Based on our results, more children would qualify for services when tested in natural environments using TMQ and GMQ scores. It also took significantly longer …

Exploring The Five Phases Of Physical Therapist Professional Development Advanced By The Clinical Doctorate Degree, Salome V. Brooks

All PTHMS Faculty Publications

The American Physical Therapy Association (APTA) 2020 strategic plan mandated that the clinical doctor of physical therapy degree (DPT) will be the minimum practice standard. The APTA failed to articulate a functional practice description recognizing the varying levels of preparation. The current literature validates the existence of a stepwise pattern of professional development in similarly evolving disciplines. Applied nursing research by Benner (Benner model of professional development, 2001) identified five stages of professional development and characteristics that were useful in the discipline's advancement. The purpose of the study was to apply the structure of the Benner Model to physical therapy …
