Acceleration Profiles Of Adolescent Soccer Players Across A Season, Jake A. Melaro

Doctoral Dissertations

The injury risk inherent to soccer can be affected by external training loads and intrinsic factors. These intrinsic factors (sex, mass, strength, coordination, etc.) in young athletes can be rapidly altered the near their peak height velocity (PHV) during puberty, modifying their movement complexity and, potentially, their injury risk. While quantification of movement complexity through multiscale entropy analysis have been used in past biomechanical investigations, no studies have incorporated this analysis on tibial accelerometry signals collected in these maturing athletes. The purpose of this study is to collect tibial acceleration data from youth soccer athletes during several discrete drills and …

Translational Models For Advancement Of Regenerative Medicine And Tissue Engineering, Kristin Marie Bowers

Doctoral Dissertations

At the root of each regenerative medicine or tissue engineering breakthrough is a simple goal, to improve quality of healing, thus improving a patient’s quality of life. Each tissue presents its own complexities and limitations to healing, whether it is the scarring nature of tendon healing or the mechanical complexity driving bone regeneration. Preclinical, translational models aim to reflect these complexities and limitations, allowing for effective development and refinement of tissue engineered therapeutics for human use. The following body of work explores several of these translational models, both utilizing them for tissue regenerative therapy development and evaluating the benefits and …

Influence Of Patient Satisfaction Of Total Knee Replacement Patients On Stair Negotiation And Walking Biomechanics, Strength, And Balance, Kevin Alan Valenzuela

Doctoral Dissertations

Total knee replacement (TKR) patients have shown alterations in lower extremity biomechanics during level ground walking and stair negotiation, strength levels, and balance abilities, however, it is unknown how dissatisfied TKR patients compare to satisfied TKR patients in these activities. Study One examined the lower extremity biomechanics of dissatisfied and satisfied TKR patients during level ground walking. Study Two investigated knee biomechanics during stair ascent and descent activities. Study Three compared isokinetic strength, balance abilities, deep knee flexion abilities, and functional abilities of the dissatisfied patients to the satisfied patients. Study Four performed a logistic regression as a means of …

Effects Of Lateral Shoe Wedges And Toe-In Foot Progression Angles On The Biomechanics Of Knee Osteoarthritis During Stationary Cycling, Jacob Kale Gardner

Doctoral Dissertations

Exercise is important for individuals with knee osteoarthritis (OA) but certain activities can be painful and discourage participation. Cycling is commonly prescribed for OA but practically no previous literature exists. Due to their altered knee kinematics, OA patients may be at greater risk of OA progression or other knee injuries during cycling. The purpose of Study One was to investigate the effects of lateral wedges on knee joint biomechanics and pain in patients with medial compartment knee OA. The purpose of Study Two was to investigate the effects of toe-in foot progression angles on the same variables. Thirteen OA subjects …

The Effect Of Technique Instruction On Biomechanical Risk Factors Associated With Acl Injury Risk In Female Recreational Athletes, Jeremiah Jackson Tate

Doctoral Dissertations

Background: Epidemiological studies have demonstrated higher ACL injury rates in female athletes when compared to males involved in the same sport. A recent meta-analysis of ACL injury prevention programs found that technique training was a common component of programs that were successful in reducing ACL injury.

Purpose: The primary purpose was to determine the immediate and long-term effects of technique training aimed at minimizing medial knee displacement during jump-landings in female recreational athletes. The secondary purpose was to determine if any transfer of skill occurred as a result of our technique training.

Study Design: Controlled laboratory study.

Methods: A total …
