Does An Acl Autograft, Allograft Or Synthetic Graft Lead To Improved Long Term Knee Stability?, Parker Lanoue

Theses and Graduate Projects

Current literature surrounding anterior cruciate ligament (ACL) reconstruction outlines four primary classes of grafts used to replace the existing ACL. These classes include bone-patellar tendon-bone (BPTB) autografts, hamstring tendon (HT) autographs, allografts and synthetic grafts. Research has been conducted on each of these primary ACL reconstruction strategies and through this research we are looking to answer the question on which of these classes of ACL grafts in turn leads to the most improved long-term knee stability. In addition to analyzing these classes of grafts we will also inspect options along the non-surgical route to ACL repair, a more conservative approach, …

The Effects Of Generalized Stress And Anxiety On Clinical Athletic Training Students: A Qualitative Study, Morgan E. Dumont

Masters Theses, 2020-current

Stress and anxiety are present and acknowledged on our society as seven out of 10 United States adults deal with moderate stress or anxiety on a daily basis (Beiter et al., 2015). Sport research has primarily focused on student-athletes, how they struggle, and the resources that can be provided to help this population cope and manage their stress. However, there is lack of research about stress and anxiety among those individuals who provide the care to student-athletes, specifically the athletic training students within their clinical assignments. Athletic training students lead similar schedules to student-athletes by devoting time to prepare for …

Balance Of Adults With Chronic Ankle Instability Following A 6-Week Core Stability Program, Natalie Dickol

Theses and Dissertations

Ankle injuries are one of the most common injuries in the athletic population because of the anatomy of the ankle in conjunction with dynamic activity. During injury, mechanoreceptors are damaged, effecting neuromuscular control. Lack of neuromuscular control puts patients at risk for re-injury. Chronic ankle instability (CAI) has been defined as a condition associated with recurrent sprains and persistent symptoms, including feelings of "giving way," loss of function and limited movement and continuous ankle pain. Patients with CAI are commonly shown to have functional deficits in postural control, such as overcompensating on the uninvolved limb or unable to maintain proper …

Background and Purpose of the Study: Sport-related concussions are a major public health issue, particularly so in the setting of sports. Sports dominate American culture and with millions of athletes of all ages participating in these sports these athletes predispose themselves to the risks of sport-related concussions. High-school athletes are of particular interest because of the heightened risks of long-term consequences and of particular note second impact syndrome, which is a catastrophic injury primarily reported in the adolescent aged athlete. Appropriate concussion assessment and management is necessary for reducing the possibility of these long- term effects of concussions. Properly trained …

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. …

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 …

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 …

Relationship Between One Repetition Maximum Parallel Squat And Jump Squat Peak Power, Corey Klitzke

Masters Theses

Jump squats are a simple exercise that can be used to train lower body power. Unlike many other methods of power training, jump squats do not require any specialized equipment (platforms, bumper plates, etc.). Jump squats can be used when other forms of power training are not available or are not allowed. In order to most efficiently train power, the intensity must balance force and velocity. The purpose of this study was to find the intensity that yields the peak power output of a jump squat. 12 participants (9 males, 3 female) participated in the study. Each participant completed a …

Bilateral And Unilateral Resistance Training And Athletic Performance, Brendyn B. Appleby

Theses: Doctorates and Masters

Specificity is a key programming principle for optimal transfer of physiological adaptation of training to improved athletic performance. In resistance training, it has long been identified that the closer the mechanical specificity between the training exercise and outcome performance, the greater the transfer of improved capacity. Bilateral resistance exercises are predominately prescribed for the development of maximum strength and are well demonstrated to enhance athletic performance. However, unilateral exercises appear to demonstrate greater specificity to movements such as running and change of direction as these movements are predominantly single leg actions. Nonetheless, the unstable nature and comparatively lower magnitude of …

The Feasibility Of Gathering Patient-Reported Outcome Measures On Individuals With Acute Ankle Sprains In A Busy Clinic Environment, Ryan Reeson

Electronic Thesis and Dissertation Repository

Ankle sprains are the most common sports injury and can lead to long-term deficits. Patient-reported outcome measures (PROMs) may assist clinicians in evaluating the recovery trajectory of patients with ankle sprains. However, before a large-scale study can be performed, it is necessary to determine whether it is feasible to collect PROMs in a busy clinic environment. This study had a narrow recruitment window but the consent rate was 100%. Ten patients at Fowler Kennedy Sport Medicine Clinic were followed for up to six visits. Three PROMs that characterized lower extremity function were measured. The measurement completion rate decreased from 100% …

Seasonal Changes In Sleep, Rpe, And Scoring Percentage In Division One Collegiate Female Basketball Players, Lindsay Perrin, Dr. Stephen Rossi

Honors College Theses

Basketball season occurs over several months and involves heavy traveling, training, competing, and scholarly duties. These demands do not allow much time for rest and recovery. A lack in the quantity and quality of sleep can reduce the ability to manage stress and reduce recovery from training and competition. This can affect the health and well-being of the athlete and their success on the court. In college, sleep schedules may change from high school by staying up later and sleeping in more. College students typically sleep between six and seven hours a night which is less than the recommended nine …
