Grant, Alon Friedman, Ronel Veksler, Michael G. Molloy, James F. Meaney, Niall Pender, David Camarillo, Colin P. Doherty, Matthew Campbell

Articles

Whereas the diagnosis of moderate and severe traumatic brain injury (TBI) is readily visible on current medical imaging paradigms (magnetic resonance imaging [MRI] and computed tomography [CT] scanning), a far greater challenge is associated with the diagnosis and subsequent management of mild TBI (mTBI), especially concussion which, by definition, is characterized by a normal CT. To investigate whether the integrity of the blood-brain barrier (BBB) is altered in a high-risk population for concussions, we studied professional mixed martial arts (MMA) fighters and adolescent rugby players. Additionally, we performed the linear regression between the BBB disruption defined by increased gadolinium contrast …

Hip Labral Injury Worsens After Platelet Rich Plasma Injections: A Case Report, Brennan M. Wright, Carmen Wong

Graduate Medical Education (GME) Resident and Fellow Research Day Posters

Case Description

A 47-year-old active male presented with 2.5 years of right hip pain suggestive of labral pathology. Ice, heat, celecoxib, ibuprofen, diclofenac gel, and physical therapy provided minimal relief. A diagnostic intra-articular bupivacaine injection resolved the pain. A subsequent MR arthrogram revealed a non-displaced tear of the right anterior superior acetabular labrum.

In pursuit of conservative treatment, the patient agreed to a series of 3 right hip intra-articular PRP (platelet rich plasma) injections. When he presented for the second injection, he reported his pain had decreased by 20% and he was tolerating light running. Due to improvement in symptoms, …

Efficacy Of Pain Scales In Athletic Populations And Paired With Aglometric Measurements, Elisabeth Anne Ohrnberger

Online Theses and Dissertations

Objective: Pain is the most common symptom and reason for why affected individuals seek out medical attention for injuries. The most common pain scales are: the numerical rating scale (NRS), 5-point verbal rating scale (VRS-5), and visual analog scale (VAS) but there is no gold standard established to measure unidimensional pain intensity. Algometry is an objective technique to measure pain pressure threshold and tolerances. However, there is little research on which scale is best suited to assess pain intensity in different demographics; including athletic populations and other types of groups; as well as, whether subjective pain scale measurements can be …

Body Composition Assessment Results And Predicting Injury Patterns In Collegiate Musicians, Ellen Reinhold

Online Theses and Dissertations

Objective: It is known that a higher body mass index (BMI) is associated with increased risk of injury, but it is unknown whether there is an association between increased risk of injury and body composition. Currently the data comes from competitive sports, with little data in performing arts, specifically marching band. The primary aim of this study was to determine if body composition assessments can predict musculoskeletal injury (MSI) occurrence in marching band participants. Methods: Body composition was measured using a duel X-ray absorptiometry (DXA) scan at the beginning of both the fall 2018 and 2019 seasons. Data on injuries …

Caffeine Ingestion Enhances Repetition Velocity In Resistance Exercise: A Randomized, Crossover, Double-Blind Study Involving Control And Placebo Conditions, Jozo Grgic, Sandro Venier, Brad J. Schoenfeld, Pavle Mikulic

Publications and Research

We aimed to examine the effects of placebo and caffeine compared to a control condition on mean velocity in the bench press exercise. Twenty-five resistance-trained men participated in this randomized, crossover, double-blind study. The participants performed the bench press with loads of 50%, 75%, and 90% of one-repetition maximum (1RM), after no supplementation (i.e., control), and after ingesting caffeine (6 mg/kg), and placebo (6 mg/kg of dextrose). At 50% 1RM, there was a significant effect of caffeine on mean velocity compared to control (effect size [ES] = 0.29; p = 0.003), but not when compared to placebo (ES = 0.09; …

Association Between Eccentric Knee Flexor Strength And Hamstring Injury Risk In 185 Elite Gaelic Football Players, Mark Roe, Eamonn Delahunt, Malachy Mchugh, Conor Gissane, Shane Malone, Kieran Collins, Catherine Blake

Articles

Hamstring strains are the most common time-loss injury in elite Gaelic football affecting over 20% of players per season. Thus, there is a need to identify factors contributing to the onset of hamstring injuries in order to inform injury risk management strategies. The current study investigated whether eccentric knee flexor strength and between-limb imbalances were associated with increased risk of sustaining a timeloss hamstring injury in elite Gaelic football players. A total of 185 elite male players (26.9 ± 2.7 years, 86.4 ± 6.2 kg, 183.4 ± 5.6) were prospectively followed for 12 weeks from the day of testing. Injury …

Clinical And Neurophysiological Effects Of Dry Needling On Individuals With Chronic Ankle Instability, Jennifer Mullins

Theses and Dissertations--Rehabilitation Sciences

Ankle sprains are generally considered innocuous injuries; however, as many as 74% of patients will develop chronic symptoms. 1-3 Chronic ankle instability (CAI) is defined by a history of ankle sprain accompanied by ongoing bouts of giving way, residual ankle sprain symptoms, and a decrease in patient-perceived function. As understanding of sensorimotor deficits in individuals with CAI have advanced, treatment strategies have evolved to include a robust focus on balance training to mitigate dynamic and static postural control impairments exhibited in individuals with CAI. A problem arises as these improvements have not been conclusively linked to a decrease in CAI. …

Anterior Cruciate Ligament Injury-Induced Alterations In Inflammation And Muscle Physiology, Emily R. Hunt

Theses and Dissertations--Rehabilitation Sciences

Long term weakness and atrophy of the quadriceps muscle are a direct result of anterior cruciate ligament (ACL) injuries and persist for up to 10 years post injury. Muscle atrophy ensues regardless of ligamentous reconstruction surgery, indicating that muscle atrophy following injury is a function of the ligament rupture and not reconstruction surgery. Elucidating the mechanisms underlying quadriceps atrophy following ACL rupture is crucial for developing interventions to restore proper quadriceps size and mitigate weakness thereby allowing for improved patient function. In addition to understanding the specific mechanisms that contribute to quadriceps atrophy following ACL rupture, the timing of atrophic …

Oral Contraceptives As Possible Acl Injury Prevention Method, Haley Schweizer

Capstone Showcase

ABSTRACT

Introduction: Anterior Cruciate Ligament (ACL) injuries are an upsetting setback for many athletes that require a long and costly recovery process. The injury rates are four times greater in women than men. Preventative measures that help to prevent ACL injuries are limited to stretching and strengthening. Therefore, this review aims to investigate if oral contraceptive [I] usage provides a possible new avenue for prevention of ACL injury [O] in young female athletes (ages 18-30) [P] compared to those that do not take oral contraceptives [C].

Methods: A literature review was performed though PubMed, Google Scholar, SCOPUS Database, and ClinicalKey …

The Use Of Yank-Time Signal As An Alternative To Identify Kinematic Events And Define Phases In Human Countermovement Jumping, Sofyan Sahrom, Jodie C. Wilkie, Kazunori Nosaka, Anthony J. Blazevich

Research outputs 2014 to 2021

Detailed examinations of both the movement and muscle activation patterns used by animals and humans to complete complex tasks are difficult to obtain in many environments. Therefore, the ability to infer movement and muscle activation patterns after capture of a single set of easily obtained data is highly sought after. One possible solution to this problem is to capture force-time data through the use of appropriate transducers, then interrogate the signal's derivative, the yank-time signal, which amplifies, and thus highlights, temporal force-time changes. Because the countermovement vertical jump (CMJ) is a complex movement that has been well studied in humans, …
