This study aimed to employ advanced biomechanical gait analysis to evaluate the impact of AFO intervention on gait performance among patients with PAD. Patients with claudication had hip, knee, and ankle joint kinetics and kinematics assessed using a cross-over intervention design. Participants walked over the force platforms with and without AFOs while kinematic data …

In Football Players With Scaphoid Fractures, How Does Surgical Intervention Compare To A Conservative Intervention For The Outcomes Of Repair? A Critically Appraised Topic, Kaitlin Brun, Meggan Bartok, Caitlin Craig, Ally Smith

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

CLINICAL SCENARIO

Scaphoid injuries are common in high impact or high collision sports with 11% of all hand injuries and 60%-70% of all carpal injuries being attributed to the scaphoid bone. Athletes at the highest risk include males ages 20-24 years of age and those who participate in football, basketball, or ice hockey. Fracture of the scaphoid are often misdiagnosed which increase the chance of a nonunion fracture. Currently most scaphoid fractures are treated either conservatively or with surgical interventions. The increasing knowledge of this injury leads us to question the best treatment options for future football athletes.

Post-Activation Potentiation Following Maximal Effort, Multi-Joint, Isokinetic Eccentric Contractions, Tom Dickey

All Graduate Reports and Creative Projects, Fall 2023 to Present

Post-activation potentiation (PAP) is a phenomenon that can enhance muscle performance following maximal or near-maximal muscle contractions. While the effects of concentric and isometric conditioning contractions on PAP have been studied, less is known about the influence of eccentric muscle actions. This study investigated the effects of a multi-joint eccentric overload (EOL) protocol on PAP expressed through countermovement jump (CMJ) height and isokinetic peak force (PF) outcome measures. Twenty-eight recreationally trained participants (18-30 years) completed three visits in a randomized, counterbalanced design. Following familiarization, participants performed either an EOL protocol involving 2 sets of 6 maximal isokinetic eccentric contractions or …

Sex Differences In Tibial Compression During Load Carriage Running On Challenging Surfaces, Eric Brian Francis

Boise State University Theses and Dissertations

Introduction: Tibial stress fracture is a common and destructive musculoskeletal issue for military, particularly female, personnel. Common military tasks, such as walking and running with body borne load, reportedly lead to lower limb biomechanics that elevate tibial stress fracture risk. Yet, it is unknown if similar increases are evident when running with heavy load – particularly over varied terrain personnel commonly navigate during military exercises. Purpose: This study sought to quantify vertical ground reaction force (GRF) and tibial compression while participants ran with body borne load over challenging surfaces, and determined whether they differed between sexes. Hypothesis: Participants will exhibit …

The biomechanical impacts of infants spending time at an incline is an understudied area, and almost 12,000 emergency room visits occur each year due to injuries involving commercial infant products. Therefore, the overall objective of this study was to understand how an infant’s …

The Effect Of Gentle Yoga On Average Daily Step Count, Francesca D'Agrosa

Graduate Theses and Dissertations

While walking is a widely accessible form of exercise that is highly effective at increasing overall wellness (Kadir et al., 2019; Zhao et al., 2015) and is a recommended form of physical activity for overweight and obese individuals, studies still indicate low step counts and levels of physical activity in people with obesity (Shultz et al., 2011). Sedentary overweight individuals may avoid walking for several reasons, including physiological and/or biomechanical factors that make walking more difficult. This study attempted to explore and address these avoidant behaviors by employing a single-case ABAB reversal design to implement bi-weekly gentle yoga sessions over …

A Comparison Of Spinal Reflex Function And Morphological Adaptations Of The Achilles Tendon Between Individuals Chronically Post-Stroke And Healthy Controls, Migi Contreras, Mira Seekins, Johanna Mendez, Trevor Diez

UNLV Theses, Dissertations, Professional Papers, and Capstones

Purpose/Hypothesis: The hallmark gait deviation in individuals with post-stroke hemiparesis is slow walking speed. Reduction in gait speed after stroke is influenced by decreased propulsive forces, which may likely be related to impaired spinal circuit function and spasticity of the paretic plantarflexors. Chronic muscle tone maladaptations in paretic ankle plantarflexors can result in altered Achilles tendon (AT) morphology, therefore leading to altered mechanical properties, force transmission capabilities and subsequent insufficient propulsive forces during walking. The purpose of this study is to characterize the chronic maladaptations in both the spinal Ia afferent loop excitability and AT morphology after stroke lesions in …

Effects Of Balance Training On Spinal Reflexive Excitability Modulation, Corticospinal Excitability, And Balance Performance In Individuals With Chronic Ankle Instability, Sunghoon Chung

Rehabilitation Sciences Theses & Dissertations

Chronic ankle instability (CAI) is a neurophysiologic deficit resulting in diverse sensorimotor impairments. Following acute ankle sprains, pain, mechanical instability, and joint deafferentation reduce sensory input to the central nervous system (CNS). In response, the CNS sends altered motor signals to lower extremity muscles. These CNS changes contribute to various neuromuscular impairments in CAI patients, the most common of which is reduced balance performance. Specifically, CAI patients struggle to modulate spinal reflex excitability of the soleus muscle when progressing from simpler to more complex balance tasks. This overreliance on spinal reflexes results in inconsistent activation of the ankle stabilizing muscle. …

Building upon existing research in motor learning and sensorimotor control, this thesis explores how the performance of a real-world task (playing a simple musical piece on the violin) is impacted by the spatial re-arrangement of the violin’s strings, and how performance recovers with practice (relearning). I recorded audio performances and bow kinematics as violinists with a wide range of prior skills played a familiar 2-octave G-Major arpeggio 50 times. Some subjects played all 50 arpeggios on a violin with the standard string arrangement (the control violin). Another set of subjects played the middle 30 arpeggios with a “similar” violin with …

Reliability Of Popliteal Artery Flow-Mediated Dilation In The Seated Position, Taskina Akhter

Rehabilitation Sciences Theses & Dissertations

Flow-mediated dilation (FMD) is a noninvasive measurement of endothelial function, which is a useful prognostic tool for cardiovascular disease risk. Despite its widespread use since 1992, the reproducibility of FMD varies widely between studies. This variability in reproducibility is especially significant in the case of the popliteal artery due to different methodological approaches. Studies perform popliteal FMD in various body positions, with the prone and seated positions most common. However, no studies have examined the reproducibility of both the seated and prone positions of the popliteal artery FMD. Therefore, the aim of this study is to examine the test-retest and …
