Foot Volume Change During Long Distance Running In Healthy Adults, Meghan Boni, Istvan Takacs, Rebecca Wilson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background and purpose: Healthy adults frequently engage in running as a means of cardiovascular exercise. Larger running shoes are often chosen based on common beliefs that feet swell during running, yet many continue to encounter foot injuries, such as blisters, as a result of this activity. Previous research has analyzed the changes in foot volume during short bouts of activity. However, there has been limited research on the effect of long distance running on foot volume, which is where many of these injuries are seen. The purpose of this study was to examine the effects of long distance running, defined …

A Standardized Evidence-Based Model Of Orthopaedic Physical Therapy Practice: A Quest For The Holy Grail?, Guy G. Simoneau

Physical Therapy Faculty Research and Publications

The growth of knowledge in orthopaedic physical therapy practice is on an exponential trajectory. This growth is occurring simultaneously for many aspects of evidence-based practice: diagnosis, prognosis, treatment, and harm – with increasingly more sophisticated basic science and mechanistic studies guiding and supporting the clinical research endeavors. Just how close are we to the day when we can clearly establish the accuracy of our diagnoses, regardless of the model used, and then can confidently inform our patients of the most effective treatment approach and the expected outcomes, as well as any potential harm? This knowledge is being created now, and …

The Effect Of Movement Rate And Complexity On Functional Magnetic Resonance Signal Change During Pedaling, Jay P. Mehta, Matthew D. Verber, Jon A. Wieser, Brian D. Schmit, Sheila M. Schindler-Ivens

Physical Therapy Faculty Research and Publications

We used functional magnetic resonance imaging (fMRI) to record human brain activity during slow (30 RPM), fast (60 RPM), passive (30 RPM), and variable rate pedaling. Ten healthy adults participated. After identifying regions of interest, the intensity and volume of brain activation in each region was calculated and compared across conditions (p < .05). Results showed that the primary sensory and motor cortices (S1, M1), supplementary motor area (SMA), and cerebellum (Cb) were active during pedaling. The intensity of activity in these areas increased with increasing pedaling rate and complexity. The Cb was the only brain region that showed significantly lower activity during passive as compared with active pedaling. We conclude that M1, S1, SMA, and Cb have a role in modifying continuous, bilateral, multijoint lower extremity movements. Much of this brain activity may be driven by sensory signals from the moving limbs.

The Influence Of Interlimb Differences On Anterior Cruciate Ligament Injury Risk Factors In Female Collegiate Soccer Athletes, Eric Kevin Greska

Human Movement Sciences & Special Education Theses & Dissertations

Female collegiate soccer athletes suffer anterior cruciate ligament (ACL) injuries at a rate of 0.31 per 1000 athlete-exposures, with 67% of injuries expected to be from a non-contact mechanism. As well, previous studies have demonstrated dissimilarity in non-contact ACL injuries relative to dominant and non-dominant legs; with the non-dominant leg being the involved side in 48-67% of reported incidents. The aim of this study was to examine lower extremity neuromechanics relative to leg dominance during an unanticipated sidestep cutting task, with differing states of fatigue and training.

Twenty female collegiate soccer players performed three valid trials for both the dominant …

Vision 2020 is the official vision statement of the American Physical Therapy Association (APTA). Drafted by the APTA House of Delegates in 2000, this statement contains 6 elements: autonomous physical therapist practice, direct access, Doctor of Physical Therapy and lifelong education, evidence-based practice, practitioner of choice, and professionalism. Autonomous practice has been operationally defined by the APTA primarily through its characteristics: “Physical therapists accept the responsibility to practice autonomously and collaboratively in all practice environments to provide best practice to the patient/client. Autonomous physical therapist practice is characterized by independent, self-determined, professional judgment and action.” The Section on Geriatrics has …

Push-Pull Control Of Motor Output, Michael D. Johnson, Allison Hyngstrom, Marin Manuel, C J. Heckman

Physical Therapy Faculty Research and Publications

Inhibition usually decreases input–output excitability of neurons. If, however, inhibition is coupled to excitation in a push–pull fashion, where inhibition decreases as excitation increases, neuron excitability can be increased. Although the presence of push–pull organization has been demonstrated in single cells, its functional impact on neural processing depends on its effect on the system level. We studied push–pull in the motor output stage of the feline spinal cord, a system that allows independent control of inhibitory and excitatory components. Push–pull organization was clearly present in ankle extensor motoneurons, producing increased peak-to-peak modulation of synaptic currents. The effect at the system …

Department of Physical Therapy Faculty Papers

Abstract With the advent of new interventions targeted at both acute and chronic spinal cord injury (SCI), it is critical that techniques and protocols are developed that reliably evaluate changes in upper limb impairment/function. The Graded Redefined Assessment of Strength Sensibility and Prehension (GRASSP) protocol, which includes five subtests, is a quantitative clinical upper limb impairment measure designed for use in acute and chronic cervical SCI. The objectives of this study were to: (1) establish the inter-rater and test-retest reliability, and (2) establish the construct and concurrent validity with the International Standards of Neurological Classification of Spinal Cord Injury (ISNCSCI), …

Motor Control Of Exercise That Emphasizes Speed Post-Stroke, Vicki L. Gray

Electronic Thesis and Dissertation Repository

Purpose: To investigate whether a single session of closed kinetic chain (CKC) and open kinetic chain (OKC) exercises emphasizing speed post-stroke could evoke changes in the motor control and whether these improvements would transfer to postural tasks.

Methods: Thirty-two individuals post-stroke and 32 age- and sex- matched controls performed a single session of 50 fast squats and steps (Chapter 3). Internal perturbations (arm raise/load drop) were used to assess postural responses before exercises (Pre), immediately after exercises (Post) and 15 minutes after exercises (Retention) (Chapter 4). Eleven individuals post-stroke performed a single session of 50 fast knee and ankle OKC …

Effect Of A Single High-Fat Meal And Vitamins On The Circulatory Response To Local Heat In Koreans And Caucasians, Jongeun Yim

Loma Linda University Electronic Theses, Dissertations & Projects

Blood flow mediated by the vascular endothelium plays an important role in removing heat from the skin. Asians who have thrifty genes have impaired endothelial function (EF) due to the westernized high fat (HF) dietary lifestyle. Hypertriglyceridemia (HTG) can produce free radicals which reduces the bioavailability of the endothelium derived relaxing factor, nitric oxide (NO). EF, as measured by the blood flow response (BFR) to heat, occlusion and the free radical concentration after a single HF meal has not been studied in Korean-Asians compared to Caucasians. The purpose of this study was to evaluate baseline and postprandial EF as related …

Old adults exhibited a longer time to task failure than the young adults (23.8 ± 9.0 vs. 11.5 ± 3.9 min, …

Vitamin D And Brain Imaging In The Elderly: Should We Expect Some Lesions Specifically Related To Hypovitaminosis D?, Cédric Annweiler, Manuel Montero-Odasso, Susan W Muir, Olivier Beauchet

Physical Therapy Publications

Hypovitaminosis D is associated with cognitive decline in the elderly, but the issue of causality remains unresolved. Definitive evidence would include the visualization of brain lesions resulting from hypovitaminosis D. The aim of the present article is to determine, through a literature review, the location and nature of possible brain disorders in hypovitaminosis D. We found limited brain-imaging data, which reported ischemic infarcts and white matter hyperintensities in hypovitaminosis D, though did not provide their specific location or report any focal atrophy. Based on the finding of executive dysfunctions (i.e., mental shifting and information updating impairments) in the presence of …

A Prototype Head-Motion Monitoring System For In-Home Vestibular Rehabilitation Therapy, Pamela T. Bhatti, Susan J. Herdman, Siddarth Datta Roy, Courtney D. Hall, Ronald J. Tusa

ETSU Faculty Works

This work reports the use of a head-motion monitoring system to record patient head movements while completing in-home exercises for vestibular rehabilitation therapy. Based upon a dual-axis gyroscope (yaw and pitch, ± 500-degrees/sec maximum), angular head rotations were measured and stored via an on-board memory card. The system enabled the clinician to document exercises at home. Several measurements were recorded in one patient with unilateral vestibular hypofunction: The total time of exercise for the week (118 minutes) was documented and compared with expected weekly exercise time (140 minutes). For gaze stabilization exercises, execution time of 60 sec was expected, and …

Influence Of Foot Position On Lower Extremity Muscle Activity, Hayley J. Letvin

Physical Therapy Scholarly Projects

Being that the anterior cruciate ligament (ACL) is the most commonly torn ligament, much research has been performed regarding this matter. Females have been found to be more likely to tear their ACL. This may be due to strength, structural (anatomical), hormonal, and neuromuscular differences compared to men. Several studies have also been conducted to help improve preventative measures with using strengthening and neuromuscular training programs. Many speculations have been made about the precipitating factors of an ACL injury. The general consensus in regard to foot placement is that the foot is usually placed in pronation during an ACL tear. …

Department of Physical Therapy Faculty Papers

We sought to determine if tendon inflammatory and histopathological responses increase in aged rats compared to young rats performing a voluntary upper extremity repetitive task, and if these changes are associated with motor declines. Ninety-six female Sprague-Dawley rats were used in the rat model of upper extremity overuse: 67 aged and 29 young adult rats. After a training period of 4 weeks, task rats performed a voluntary high repetition low force (HRLF) handle-pulling task for 2 hrs/day, 3 days/wk for up to 12 weeks. Upper extremity motor function was assessed, as were inflammatory and histomorphological changes in flexor digitorum and …
