The Effect Of Extensible And Non-Extensible Lumbar Belts On Trunk Postural Balance In Subjects With Low Back Pain And Healthy Controls, Ali Shahvarpour, Richard Preuss, Christian Larivière

Études primaires

Background

Previous findings suggest that wearing a lumbar belt may benefit some patients with low back pain; however, the mechanisms of action are not yet fully understood.

Research question

The effect of wearing two flexible (extensible and non-extensible) lumbar belts on trunk postural control was investigated during an unstable sitting task.

Methods

Healthy subjects and subjects with LBP sat on a wobbling chair, with and without the lumbar belts. Chair rotation was measured in the sagittal and frontal planes, and 10 linear and nonlinear measures of balance were computed to assess the quantity (3 measures) and quality (7 measures) of …

Predictors And Health Outcomes Of Treatment-Resistant Depression Among Adults With Chronic Non-Cancer Pain Conditions And Major Depressive Disorder, Drishti Shah

Graduate Theses, Dissertations, and Problem Reports (ETD)

Understanding major depressive disorder (MDD) as a comorbidity in patients with chronic non-cancer pain conditions (CNPC) is of importance because of the high prevalence and well documented bi-directional relationship between MDD and pain. Furthermore, presence of CNPC among adults with MDD often reduces benefits of antidepressant therapy, thereby increasing the possibility of treatment resistance. Treatment-resistant depression (TRD) commonly defined as insufficient response to multiple antidepressant trials, often worsens depression and pain symptoms and can amplify the clinical and economic burden among adults with CNPC and MDD. Additionally, long-term opioid therapy (LTOT) may be prescribed at a higher rate to adults …

Comparison Of Osteoporosis Knowledge, Beliefs, Attitudes, And Behavior Among College Students Of Various Racial/Ethnic Groups, Lauri Deruiter-Willems

Faculty Research and Creative Activity

Osteoporosis is known as a pediatric disease with geriatric consequences. The need forbone health, awareness of controllable risk factors and prevention of osteoporosis begins duringone’s youth (Campbell, 2012; Cannada, 2016; Evenson & Sanders, 2016; Edmonds, Turner, &Usdan, 2012; Ford et al., 2011; Gammage et al., 2009; Gammage et al., 2012). Currently, mosthealth information and health campaigns focus on older adults. To promote measurableimprovements in reducing the number of cases of osteoporosis, the focus for change needs tostart as early as teenage and young adult age. In addition to the general population trends, ratesspecifically associated with the nonwhite U.S. population are …

Better Bone Health: Health Community Clinic, Naijah Hughes, Dakota Turnage, Kintara Williams, Christopher Fangna

DC Health and Academic Prep Program (DC HAPP)

Osteoporosis affects the quality of life, the ability to work, and basic activities of daily living. Osteoporosis is a disease marked by reduced bone strength leading to an increase in fractures. Every day, our body breaks down old bone and puts new bone in its place. As we get older, our bones break down more bone than they put back. If you do not take the steps to keep your bones healthy, you may lose too much bone and osteoporosis may develop. Men and women are both affected by osteoporosis. In the United States, an estimated 5.3 million people aged …

The Effects Of An 8-Week Stabilization Exercise Program On Lumbar Multifidus Muscle Thickness And Activation As Measured With Ultrasound Imaging In Patients With Low Back Pain: An Exploratory Study, Christian Larivière, Dany H. Gagnon, Sharon M. Henry, Richard Preuss, Jean-Pierre Dumas

Études primaires

Background

Lumbar stabilization exercise programs (LSEP) produce positive effects on clinical outcomes, but the underlying mechanisms remain relatively unexplored. Psychological and neuromuscular mechanisms can be involved, such as a better activation of the lumbar multifidus, which represents one possibility.

Objectives

To determine the following: (1) the effect of an LSEP on lumbar multifidus muscle thickness and activation, as measured with rehabilitative ultrasound imaging (RUSI), in patients with low back pain (LBP); (2) the correlation between RUSI measures and any change in clinical outcomes following the LSEP; and (3) the reliability of RUSI measures in control subjects over 8 weeks.

Trunk Postural Adjustments: Medium-Term Reliability And Correlation With Changes Of Clinical Outcomes Following An 8-Week Lumbar Stabilization Exercise Program, Jean-Alexandre Boucher, Richard Preuss, Sharon M. Henry, Marilee Nugent, Christian Larivière

Études primaires

Background

Low back pain (LBP) has been previously associated with delayed anticipatory postural adjustments (APAs) determined by trunk muscle activation. Lumbar stabilization exercise programs (LSEP) for patients with LBP may restore the trunk neuromuscular control of the lumbar spine, and normalize APAs. This exploratory study aimed at testing the reliability of EMG and kinematics-based postural adjustment measures over an 8-week interval, assessing their sensitivity to LBP status and treatment and examining their relationship with clinical outcomes.

Methods

Muscle activation of 10 trunk muscles, using surface electromyography (EMG), and lumbar angular kinematics were recorded during a rapid arm-raising/lowering task. Patients with …

Trunk Musculoskeletal Response In Maximum Voluntary Exertions: A Combined Measurement-Modeling Investigation, F. Ghezelbash, Z. El Ouaaid, A. Shirazi-Adl, A. Plamondon, N. Arjmand

Études primaires

Maximum voluntary exertion (MVE) tasks quantify trunk strength and maximal muscle electromyography (EMG) activities with both clinical and biomechanical implications. The aims here are to evaluate the performance of an existing trunk musculoskeletal model, estimate maximum muscle stresses and spinal forces, and explore likely differences between males and females in maximum voluntary exertions. We, therefore, measured trunk strength and EMG activities of 19 healthy right-handed subjects (9 females and 10 males) in flexion, extension, lateral and axial directions. MVEs for all subjects were then simulated in a subject-specific trunk musculoskeletal model, and estimated muscle activities were compared with EMGs. Analysis …

Obesity And Obesity Shape Markedly Influence Spine Biomechanics: A Subject-Specific Risk Assessment Model, Farshid Ghezelbash, Aboulfazl Shirazi-Adl, André Plamondon, Navid Arjmand, Mohammad Parnianpour

Études primaires

Underlying mechanisms of obesity-related back pain remain unexplored. Thus, we aim to determine the effect of obesity and its shapes on the spinal loads and the associated risks of injury. Obesity shapes were initially constructed by principal component analysis based on datasets on 5852 obese individuals. Spinal loads, cycles to vertebral failure and trunk stability margin were estimated in a subject-specific trunk model taking account of personalized musculature, passive ligamentous spine, obesity shapes, segmental weights, spine kinematics and bone mineral density. Three obesity shapes (mean and extreme abdominal circumferences) at three body weights (BWs) of 86, 98 and 109 kg …

Calcium Phosphate As A Key Material For Socially Responsible Tissue Engineering, Vuk Uskoković, Victoria M. Wu

Pharmacy Faculty Articles and Research

Socially responsible technologies are designed while taking into consideration the socioeconomic, geopolitical and environmental limitations of regions in which they will be implemented. In the medical context, this involves making therapeutic platforms more accessible and affordable to patients in poor regions of the world wherein a given disease is endemic. This often necessitates going against the reigning trend of making therapeutic nanoparticles ever more structurally complex and expensive. However, studies aimed at simplifying materials and formulations while maintaining the functionality and therapeutic response of their more complex counterparts seldom provoke a significant interest in the scientific community. In this review …

The Effect Of Chronic Sleep Deprivation On Tumor Necrosis Factor Alpha And Bone Health In Peri-Menopausal Rats, Megan Robertson, Derek Booth, Erin Wainwright, Cody Arbuckle, Frank Frisch

Student Scholar Symposium Abstracts and Posters

Post-menopausal osteoporosis is a common syndrome in the United States. The cessation of estrogen signaling coupled with the production of pro-inflammatory cytokines from sleep deprivation leads to an even greater risk of post-menopausal osteoporosis by creating an imbalance between osteoblasts and osteoclasts. With estrogen no longer present to regulate the concentration of osteoclasts and pro-inflammatory cytokines increasing production of osteoclasts, bone is degraded at a faster rate than it is formed. One of the most common treatments for osteoporosis is Zolendronate (a nitrogenous bisphosphonate), which decreases the number of osteoclasts in bone. This preliminary study looked at the effects on …

The Effect Of Patient Reminders On Osteoporosis Screenings, Billie-Ann Black

Evidence-Based Practice Project Reports

Osteoporosis is characterized by reduction of bone mass and compromised bone strength, resulting in an increased fracture risk. Since a reduction of bone mass has been shown to be predictive of future fracture risk, prevention strategies target screening those patients at risk for decreased bone mass by using bone mineral density (BMD) dual energy x-ray absorptiometry (DXA) scans. Current national guidelines recommend that all women 65 years and older undergo BMD testing using central DXA every two years. Despite these recommendations, women age 65 years and older still do not participate in this screening. Greater rates of osteoporosis screening could …

Job Accommodation In The Automobile Industry : Addressing The Problem Of Lateral Epicondylitis, Thanigaivel Ashwin Raj

Theses and Dissertations (ETD)

Cumulative trauma disorders are musculoskeletal problems such as carpal tunnel syndrome, rotator cuff tendinitis, and epicondylitis which can affect assembly line workers. The injuries are thought to result from repetitive motions performed under excessive loads in anomalous postures. The project aimed to design, build, install, and evaluate worksite accommodation at the Saturn plant for a worker with right lateral epicondylitis. The goal was to make her fully functional in her original team which required addressing the injurious aspects of the task that caused or aggravated her injury.

A process of observation, interview, and analysis identified “the door mount” operation on …
