Under the Supervision of Brooke A. Slavens, PhD

This project investigated upper extremity (UE) motion and functional outcomes before and after full-thickness supraspinatus rotator cuff (RC) repair through kinematic analyses of three Activities of Daily Living (ADL) tasks. RC repair is a standard procedure known to alleviate pain, weakness, and stiffness, with improvements of decreased pain and increased range of motion (ROM). Eight (8) subjects (63.6 ± 6.3) with a supraspinatus RC tear participated in …

Performance Impact Of Different Lower-Limb Setup Positions In The Backstroke Swimming Start, Gordon E. Barkwell

Electronic Thesis and Dissertation Repository

The performance impact of different knee extension angles in the setup position for a backstroke start was evaluated using an instrumented starting surface. Ten backstroke swimmers completed maximum-effort starts in each of two setup positions: one with the knees flexed, and one with the knees extended. The start handles and touchpad were instrumented with tri-axial force plates. Activity of major hip and knee extensors was measured using surface electromyography. Body position was recorded throughout the start using two high-speed cameras. There was no difference in time to 10 m between the two conditions, indicating there is likely no advantage in …

Neuromuscular Adaptations Following Slope Walking In Individuals Post-Stroke, Eric Akoopie, Brooke Conway Kleven, Trisha Koch

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: The excitability of the H-reflex pathway in the non-impaired nervous system can be augmented by altering the different parameters of a walking task, specifically slope. We sought to examine the adaptations in soleus H-reflex excitability and foot force control following an acute bout of upslope or downslope treadmill walking in people post-stroke compared to those who are non- impaired. Methods: We recruited 12 individuals with chronic post-stroke hemiparesis and 9 age-similar non- neurologically impaired individuals. Each subject was tested over 2 sessions separated by at least 7 days. For each session, subjects walked at a self-selected walking speed on …

The Effects Of Self-Adherent Taping On Peak Inversion Angle And Eversion Moment Upon Landing During A Maximal Vertical Jump And A Depth Drop, Christopher M. Gregoire

Cal Poly Humboldt theses and projects

Ankle injuries are the most common injury in physically active adults with roughly 15% to 30% of all physical activity injuries being ankle injuries. The purpose of this study is to evaluate the effectiveness of a self-adherent ankle taping in reducing peak ankle inversion angle and peak ankle eversion moment upon landing during a max vertical jump and depth drop compared to jumping without a prophylactic ankle stabilizer.

Twelve volunteers participated in testing procedure on two separate days. Day one consisted of orientation while day two consisted of experimental data collection. The participant’s peak inversion angle and eversion moment were …

The Effect Of Soleus Fatigue During Sidestep Cutting Maneuvers: Implications For The Acl, Michael William Ciesa

Browse all Theses and Dissertations

The soleus muscle is a monoarticular plantarflexor composed slow-twitch fatigue-resistant muscle fibers. Through its attachment to the proximal tibia, contraction of the soleus muscle in a closed kinetic chain (when the foot is planted) produces a posterior pulling force on the posterior proximal tibia. The anterior cruciate ligament (ACL) is responsible for preventing anterior displacement of the tibia relative to the femur. Through the production of a posterior pulling force on the tibia, soleus muscle contraction in a closed kinetic chain could help reduce strain on the ACL. Fatigue is a neuromuscular phenomenon that can alter biomechanical strategies during athletics …
