A Literature Review Of Pain Control In Osteoarthritis Patients Using Blood Flow Restriction Training, John Gericke, Dakota Pastore, Tyler Pigott

Rowan-Virtua Research Day

Background: Osteoarthritis (OA) is a degenerative disease that mainly affects articular cartilage of joints. OA most commonly affects the knees and causes pain and reduces quality of life in older adults. Blood flow restriction (BFR) occludes arterial and venous flow during exercise using a blood pressure cuff placed on the proximal lower limb. This creates an intramuscular hypoxic environment which promotes muscle hypertrophy. High load training can cause pain and inflammation in knee OA patients due to increased stress. BFR can allow patients with knee OA to use lower loads to achieve beneficial effects of rehabilitation.

Methods: Data was ascertained …

Assessment Of Forensic And Clinical Criteria Of Orbital Blowout Fractures For Use In Bioarchaeological Analysis, Dylan E. Ornot

Honors Undergraduate Theses

Orbital blowout fractures are a particular facial fracture occurring within the inner eye orbits of the face caused by blunt force trauma to the eyeball or the lower orbital rim. This fracture is common in modern clinical contexts due to physical assaults, but examining this fracture in skeletal material can also provide insights into the patterns of interpersonal violence within the fields of bioarchaeology and forensic anthropology. Issues with analyzing this fracture in skeletal material arise due to the clinical assessment practices of blowout fractures, where medical practitioners are highly focused on the soft tissue presentations of the fracture in …

Botulinum Toxin Type A Injections For Refractory Abdominal Dystonia: A Case Report, William J. Naber Ii, Jodi M. Wilhelm, Kurt A. Kuhlman, Gabriel Howard

Graduate Medical Education Research Journal

Background: A 58-year-old male with chronic bilateral treatment resistant abdominal spasms secondary complications of ascites/ alcoholic cirrhosis. Spasms would occur 4-5 times/day, lasting minutes to hours despite a 2-year course of therapeutic and pharmacological interventions. Due to treatment refraction, 6 uniformly spaced botulinum toxin type A (BTX-A) injections were placed per side, using electromyography for audible intramuscular syringe placement confirmation, while visual confirmation was made via ultrasound. During the initial trial, 6 evenly spaced injections were performed bilaterally, uniformly distributing 80U/side. Injections began bilaterally just medial to the junction of the inferior rib cage border/ anterior axillary line and progressed …

Magnetic Resonance Imaging-Derived Microvascular Perfusion Modeling To Assess Peripheral Artery Disease, Olga A. Gimnich, Tatiana Belousova, Christina M. Short, Addison A. Taylor, Vijay Nambi, Joel D. Morrisett, Christie M. Ballantyne, Jean Bismuth, Dipan J. Shah, Gerd Brunner

School of Medicine Faculty Publications

BACKGROUND: Computational fluid dynamics has shown good agreement with contrast-enhanced magnetic resonance imaging measurements in cardiovascular disease applications. We have developed a biomechanical model of microvascular perfusion using contrast-enhanced magnetic resonance imaging signal intensities derived from skeletal calf muscles to study peripheral artery disease (PAD). METHODS AND RESULTS: The computational microvascular model was used to study skeletal calf muscle perfusion in 56 in-dividuals (36 patients with PAD, 20 matched controls). The recruited participants underwent contrast-enhanced magnetic resonance imaging and ankle-brachial index testing at rest and after 6-minute treadmill walking. We have determined associations of microvascular model parameters including the transfer …

The Chapman Bone Algorithm: A Diagnostic Alternative For The Evaluation Of Osteoporosis, Elise Levesque, Anton Ketterer, Wajiha Memon, Cameron James, Noah Barrett, Cyril Rakovski, Frank Frisch

Mathematics, Physics, and Computer Science Faculty Articles and Research

Osteoporosis is the most common metabolic bone disease and goes largely undiagnosed throughout the world, due to the inaccessibility of DXA machines. Multivariate analyses of serum bone turnover markers were evaluated in 226 Orange County, California, residents with the intent to determine if serum osteocalcin and serum pyridinoline cross-links could be used to detect the onset of osteoporosis as effectively as a DXA scan. Descriptive analyses of the demographic and lab characteristics of the participants were performed through frequency, means and standard deviation estimations. We implemented logistic regression modeling to find the best classification algorithm for osteoporosis. All calculations and …

Use Of An Optical Scanning Device To Monitor The Progress Of Noninvasive Treatments For Chest Wall Deformity: A Pilot Study, Robert E. Kelly Jr., Robert J. Obermeyer, Ann Kuhn, Frazier W. Frantz, Mohammad F. Obeid, Nahom Kidane, Frederic D. Mckenzie

Computational Modeling & Simulation Engineering Faculty Publications

Background: The nonsurgical treatment of chest wall deformity by a vacuum bell or external brace is gradual, with correction taking place over months. Monitoring the progress of nonsurgical treatment of chest wall deformity has relied on the ancient methods of measuring the depth of the excavatum and the protrusion of the carinatum. Patients, who are often adolescent, may become discouraged and abandon treatment. Methods: Optical scanning was utilized before and after the intervention to assess the effectiveness of treatment. The device measured the change in chest shape at each visit. In this pilot study, patients were included if they were …

Segmental Musculoskeletal Examinations Using Dual-Energy X-Ray Absorptiometry (Dxa): Positioning And Analysis Considerations, Nicolas H. Hart, Sophia Nimphius, Tania Spiteri, Jodie L. Cochrane, Robert U. Newton

Research outputs 2014 to 2021

Musculoskeletal examinations provide informative and valuable quantitative insight into muscle and bone health. DXA is one mainstream tool used to accurately and reliably determine body composition components and bone mass characteristics in-vivo. Presently, whole body scan models separate the body into axial and appendicular regions, however there is a need for localised appendicular segmentation models to further examine regions of interest within the upper and lower extremities. Similarly, in-consistencies pertaining to patient positioning exist in the litera-ture which influence measurement precision and analysis out-comes highlighting a need for standardised procedure. This paper provides standardised and reproducible: 1) positioning and analysis …

Mechanical Ankle Instability: Relationship With Active Joint Position Sense, Kristin K. Barnett

EWU Masters Thesis Collection

"Current research defines chronic ankle instability (CAl) as the combination of mechanical ankle instability (MAl) and functional ankle instability (FAI). Previous research has found individuals with CAl and FAI to have deficits in proprioception, more specifically joint position sense (JPS). The purpose of this study was to examine the relationship between MAl and active JPS. Twelve participants (5 male, 7 female) were selected for this study based upon their subjective ankle instability as assessed by a score on the Cumberland Ankle Instability Tool (CAIT) and objective ankle instability as assessed by measurements taken using a portable ankle arthrometer. Eligible participant's …
