The STABILITY study followed these patients up to two years postoperative, and a long-term follow-up protocol was initiated afterwards. Eighty-two patients from this center were seen at three, five and seven years postoperative as part of a long-term follow-up. Our primary outcome was a composite outcome of instability and graft failure. Secondary outcomes included patient-reported outcome measures …

The Clinical Value Of Oculomotor Assessments Across The Continuum Of Concussion, Dillon Richards

Electronic Thesis and Dissertation Repository

Concussions are complex conditions that are difficult to manage medically. Variations in symptom presentation, intricate neurophysiological processes, and the availability of a variety of possible assessment tools may contribute to this complexity. Clinicians must use a broad approach, employing both subjective symptom assessment and objective assessments to confirm a diagnosis and/or monitor progression and recovery. Oculomotor function after concussion may be an important indicator of injury, given the interconnectedness of oculomotor function, vestibulo-ocular and visual systems, and even cognition. Oculomotor function may be assessed objectively or indirectly using patient-reported symptom checklists as part of subjective assessments. One way of objectively …

Neurophysiological And Psychological Characteristics Of Individuals With History Of Lateral Ankle Sprain, Katherine Bain

Theses and Dissertations--Rehabilitation Sciences

Lateral ankle sprain (LAS) is among the most common lower limb musculoskeletal injuries impacting both the general and sport populations. Even more problematic is that approximately 70% of individuals who sustain an LAS develop residual deficits. Of that subgroup, roughly 40% develop chronic ankle instability (CAI). Chronic ankle instability is a clinical diagnosis defined by the presence of ongoing impairments following the initial LAS which may include perceived instability, pain, mechanical instability, and episodes of giving way during physical activity. Not all who sustain multiple ankle sprains or experience residual deficits fit the clinical diagnosis criteria for CAI; yet may …

Femoroacetabular Impingement Syndrome: Evaluating Postoperative Rehabilitation Progress And Return To Sport Readiness, Trevor A. Day

Electronic Thesis and Dissertation Repository

Femoroacetabular impingement syndrome (FAIS) is a common cause of non-arthritic hip pain and reduced physical activity in active young adults. It is defined as a motion-related disorder of the hip with a triad of symptoms, clinical signs, and imaging findings that represents symptomatic premature contact between the proximal femur and the acetabulum. There are two anatomical morphologies that can cause FAIS, cam, and pincer, and is a challenging clinical pathology. Patients typically undergo hip arthroscopy to repair damage to the joint and recess the bone causing the impingement. These procedures can result in positive outcomes for the patient, like reduced …

Williams Honors College, Honors Research Projects

In the world of exercise prescription there are two major protocols that are used to test an individual’s aerobic capacity at a submaximal intensity using a stationary bicycle. These protocols require participants to exercise at a constant work rate until a specified hear rate is reached. Data can then be analyzed to determine the participant’s aerobic capacity. The objective of this literature review is to look at these two tests – the Åstrand-Rhyming cycle ergometer test (ARCET) and the YMCA cycle ergometer test – and determine if one is better than the other for different populations and which one an …

Perceptions Of Ncaa Division I Baseball Pitchers On Treatment Modalities For Pitching Arm Health, Thomas Williams

Graduate Theses

Throwing athletes of all sports have similarities, even if the sport itself is very different. Throwing an object creates a great amount of stress on the body, particularly at the shoulder and the elbow. A baseball pitcher should train and compete in all three planes of movement-sagittal, frontal and transverse. Training for throwing athletes has two main goals: to increase throwing power and to reduce throwing injuries. Analyzing training habits of a throwing athlete includes an understanding of the modalities they perform in order to prevent potential injuries from occurring. Baseball pitchers are extremely susceptible to throwing injuries, and must …

Constraining Kinematics During Single-Leg Squats And Step-Ups Can Reduce Quadratus Lumborum Activation And Facilitate Gluteal Activation, Shaylyn Kowalchuk

Electronic Thesis and Dissertation Repository

Increased quadratus lumborum activation and decreased gluteal activation may lead to lateral pelvic drop and increased hip adduction and internal rotation during single-leg exercises. These activation patterns and motions are associated with low back pain or lower extremity injuries. The purpose of this study was to evaluate if mechanically restricting hip adduction and internal rotation of the femur affected muscle activation. Twenty female track and field athletes performed single-leg squats and step-ups, and the quadratus lumborum, gluteus medius and maximus muscles activations were measured with surface electromyography. This study tested the hypothesis that mechanically restricted exercises would decrease quadratus lumborum …

Injured Athletes' Preferences Regarding Source Of Emotional Support, Kristin Kutz

Honors Projects

Athletes often experience emotional distress as a result of an injury. Feelings of loss, decreased self-esteem, frustration, and anger are not uncommon. Athletic trainers (ATs) who work with injured athletes are focused on helping the progression of athletes' physical healing, but their role in helping athletes emotionally and psychologically is often unclear. There are twelve Athletic Training Education Competencies that the National Athletic Training Association requires to be taught to undergraduate AT students, one of them being psychosocial intervention and referral. However, little research has been done to define the exact role of ATs in this area, as well as …

The Effect Of Stretching And Strengthening On Patellofemoral Pain Syndrome, Heather Hollinger
