Exploring An Instrumented Balance Assessment In Athletes With Acute Mild Traumatic Brain Injury Compared To Healthy Athletes And Non-Athletes, Bryana Popa

University Honors Theses

Balance deficits are common following mild Traumatic Brain Injury (mTBI) and can persist beyond the standard recovery period. Advances in wearable technologies, such as inertial measurement units (IMUs), have increased utilization of instrumented balance assessments. There are limited studies providing normative ranges for the Balance Error Scoring System (mBESS) to characterize abnormalities in people with mTBI. This thesis provides balance ranges for athletes with acute mTBI and normative control populations completing the mBESS. Testing occurred at the university athletic facility or the Balance Disorders Laboratory at Oregon Health & Science University (OHSU) and the Veterans Affairs Portland Health Care System …

The Effects Of Strength And Conditioning On Functional Movement Screen™ Scores In Secondary School Basketball., Rollin Ross Dexter, Christopher P. Renggli, James May, Lindsay Larkins

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

Purpose: Injury prevention and mitigation are among the primary responsibilities of Athletic Trainers. Research has indicated that basketball players at the secondary-school level suffer up to 2.1 time loss injuries (TLI) per 1,000 athletic exposures (AE). It has been suggested that Functional Movement Screen (FMS™) composite and individual task scores may help determine injury risk. Researchers have suggested that a variety of strength and conditioning strategies may positively alter both composite and individual FMS™ task scores and reduce movement asymmetry. Methods: During a retrospective analysis of the records of all junior varsity and varsity basketball players at one secondary school …

Effective Treatment Of An Apparent Lateral Ankle Sprain Using A Regional Interdependent Approach With Positional Release Therapy And Mulligan Concept, Joshua K. Underwood

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, …

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; …

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 …
