Background

Low back, pelvic, and lower extremity pain are common during and after pregnancy. Understanding differences in mechanics between pregnant and non-pregnant females is a first step toward identifying potential pathological mechanisms. The primary purpose of this study was to compare joint kinetics and muscle activation during gait between females during and after pregnancy to nulliparous females.

Methods

Twenty pregnant females completed testing on three occasions (second trimester, third trimester, and post-partum), while 20 matched, nulliparous controls were tested once. Motion capture, force data, and surface electromyography were averaged across seven trials during gait. Lower extremity kinematics, lower extremity moments …

A Fatal Rectus Sheath Hematoma After A Myasthenia Crisis Case Report, Robert G. Michaud, Lesley B. Gordon

Journal of Maine Medical Center

Introduction: Rectus sheath hematomas (RSH) generally occur due to damage to the inferior epigastric artery. They are rare causes of abdominal pain or acute blood loss anemia, but are an important diagnostic consideration because they can be cryptic and are potentially fatal.

Clinical Findings: An 85-year-old female who had been admitted to the hospital for 10 days with a myasthenia crisis was found to be abruptly hypotensive with a tender abdominal mass in the left lower quadrant subtly crossing midline. She was on prophylactic anticoagulation during her hospitalization.

Main diagnosis, therapeutics, interventions, and outcomes: The patient was initially stabilized with …

A Comparison Of Denoising Methods In Onset Determination In Medial Gastrocnemius Muscle Activations During Stance, Jian Zhang, Rahul Soangra, Thurmon Lockhart

Physical Therapy Faculty Articles and Research

One of the most basic pieces of information gained from dynamic electromyography is accurately defining muscle action and phase timing within the gait cycle. The human gait relies on selective timing and the intensity of appropriate muscle activations for stability, loading, and progression over the supporting foot during stance, and further to advance the limb in the swing phase. A common clinical practice is utilizing a low-pass filter to denoise integrated electromyogram (EMG) signals and to determine onset and cessation events using a predefined threshold. However, the accuracy of the defining period of significant muscle activations via EMG varies with …

An Investigation Of Stress-Related Factors And Injury Occurrence In Division Iii Ice Hockey Athletes 2020., Christian Kiesel

Master's Theses

Many variables can factor into a student athlete sustaining an injury, but one of the most interesting is stress. The Stress and Injury Model is excellent in explaining how exactly history of stressors, personality, and coping mechanisms play a pivotal role in the stress response. If these three factors cause a negative stress response, then that will lead to an athlete becoming more likely to become injured. This study used 40 ice hockey players from a Division III NCAA institution. Each participant completed the Inventory of College Students’ Recent Life Experiences (ICSRLE) and Pittsburgh Sleep Quality Index (PSQI) every month …

In Vitro Immune Activation By Treponema Pallidum And The Effect On Osteoclastogenesis: First Experimental Step Towards An Integration Between Osteoimmunology And Paleopathology., Emily Ann Rich

College of Arts & Sciences Senior Theses

The presence of pathogens in the human body influences the expression of pro-inflammatory cytokines by activated immune cells. These cytokines, and other factors, regulate osteoclastogenesis and osteoclast activity. Through experimental osteoimmunology, interactions between the inflammatory response and bone cell physiology may provide insight into how immune processes can be translated into the lesions or abnormalities observed in the osteological record. In this research, our objective was to determine if the cytokines produced by activated immune cells increase osteoclastogenesis and osteoclast activity. To evaluate this hypothesis, we used two main protocols, one for immune activation and one for osteoclastogenesis, that utilized …

Examining Permeability And Contractility Of Skeletal Muscle In Castrated Male Mice, Evan Scott

Health Sciences Honors Papers

A common method of treating skeletal muscle injury is temperature therapy. Temperature affects one of the initial aspects of skeletal muscle healing, the increasing of vascular permeability. Previous data accumulated from the Ursinus College Skeletal Muscle Lab suggests that vascular permeability following temperature therapy is different between the anatomically intact male and female mice. However, there have not been any studies to date that are able determine the cause of these permeability differences following temperature treatment. In addition, it is currently unclear how increased vascular permeability affects skeletal muscle healing. A possible cause for these differences is the increased presence …

A Closer Look At Muscle Breakdown: An Overview Of The Causes, Complications, And Diagnostics Of Rhabdomyolysis, Jamie Holchin

Senior Honors Theses

Rhabdomyolysis is the rapid breakdown of myocytes in skeletal muscle. This condition can be triggered by a variety of things including crush injury, drugs, prolonged exercise, and venom. Although the causes can vary, the general pathophysiology of rhabdomyolysis is similar. Increased intracellular calcium ion levels instigate the breakdown of cellular and certain organelle membranes of muscle cells. Reactive oxygen species form, ATP is depleted, and the sarcoplasmic reticulum, which regulates muscle contraction, is also damaged. Necrosis ensues, leading to toxic intracellular components spreading throughout the body. Rhabdomyolysis can then lead to several complications including acute renal injury and heart arrhythmias, …

A Comparison Of Power Variables For Two Loading Methods In Weighted Vertical Jumps 2020, Jonathan Tanguay

Master's Theses

Training exercises to develop muscular strength and power, such as the weighted jump squat, commonly utilize barbells and dumbbells to increase resistance. Strength coaches often measure improvements in peak force, peak power, and rate of force development to determine effectiveness of a training program. The purpose of this study was to determine if equipment selection (barbells vs. dumbbells) affects peak force, peak power, and/or rate of force development in weighted jump squats. Thirteen physically active, college-aged males (age: 21.6 ± 2.0 years, height: 182.8 ± 9.7 cm, body mass: 87.2 ± 9.0 kg, lean mass: 72.3 ± 8.1 kg) performed …

Comparison Of Pre- And Post-Operative Shoulder Muscle Emg Profiles In Reverse Total Shoulder Arthroplasty Patients, Emily Lau, Sreten Franovic, Noah Kuhlmann, Eric C. Makhni Md, Stephanie Muh Md

Medical Student Research Symposium

Background: Deltoid muscle function is central in reverse total shoulder arthroplasty (RTSA) function; however, there is limited information available regarding changes in deltoid activity before and after surgery. Few tests exist to evaluate specific muscle metrics pre and post operatively. Surface Electromyographic (EMG) is non-invasive and allows for observation of motions with multifaceted analysis of movement with minimal patient demand. Understanding the changes in shoulder muscle activation, namely in the deltoid, in patients pre and post-RTSA can further advance understanding of the procedure and rehabilitation efforts.

Methods: Nine individuals were recruited for this study: all patients underwent RTSA by a …

Validity Of The Body Scan Scanner® And Structure Sensor To Measure Limb Volume In Healthy Adults, Mary Insana Fisher, Michaela Claire Viola, Noah James Brueckner, Madison Elizabeth Wolfe, Rachel Lynn Kremer

Physical Therapy Faculty Publications

Purpose/Hypothesis: Secondary lymphedema is a chronic condition that can develop in approximately 30 percent of women treated for breast cancer. It is important to measure limb volume changes for early detection of lymphedema, when it is possible to reverse the swelling (stage 1). Common clinical measures carry concerns of infection control (water displacement), are time consuming (truncated cone calculation using circumferential measures), or expensive (perometry). Use of a portable 3D scanner addresses these concerns, but the validity is unknown. The purpose of this phase I study is to investigate the validity of the Body Scan Scanner to measure limb volume …
