The Effects Of Therapeutic Riding On Social Skills And Sensory Functioning In Children With Autism, Betsy Donahoe-Fillmore, Mary Insana Fisher, Christy Lee, Jordan Bevins, Cristin Carter, Stephanie Dailey, Kelsey Haynes, Allison Richard, Sarah Soboslay

Physical Therapy Faculty Publications

Purpose and Significance: Therapeutic riding (TR) is equine-assisted riding lessons that are adapted for people with a wide variety of impairments and is often used as an adjunct to traditional therapies. Previous research has shown that TR helped to improve sensory functioning, cognition and social skills in children with Autism Spectrum Disorder (ASD) but sessions have typically been for 10-12 weeks. The purpose of this study was to investigate if social skills and sensory functioning improved after only 8 weeks of TR.

Subjects: Children were recruited from a local TR center. Participants included seven children (5M, 2F) with a diagnosis …

Water Entry Impact Dynamics Of Diving Birds, Saburel I. Sharker, Sean Holekamp, Mohammad M. Mansoor, Tadd T. Truscott

Biology Faculty Publications

Some seabirds (such as northern gannets and brown boobies) can dive from heights as high as 30 m reaching speeds of up to 24 m s−1 as they impact the water surface. The physical geometry of plunge diving birds, particularly of the beak, allows them to limit high impact forces compared to non-diving birds. Numerically simulated data for one species (northern gannet) provides some insight into the impact forces experienced during diving, however, no reliable experimental data with real bird geometries exist for comparison purposes. This study utilizes eleven 3D printed diving bird models of three types of birds: plunge-diving …

Head Depth And Head Speed During Competitive Backstroke Ledge Starts, Wesley J. Manz, Joel T. Greenshields, Brian V. Wright, Curtis S. Goss, Benjamin C. Skutnik, Joel M. Stager

International Journal of Aquatic Research and Education

Recently, a commercially available starting ‘ledge’ designed to reduce foot slippage during the execution of the backstroke start was introduced in competitive swimming. For the purpose of identifying potential safety consequences, the present study investigated the effect of ledge use on head depths, speeds, and distances in backstroke starts of athletes with no prior or only novice familiarity of the ledge. Competitive backstroke starts were performed with and without ledges by high school-aged (14.5 to 19.2 yr, N = 61) swimmers in 1.52 m of water during a closed testing session. A SIMI Reality Motion System in a calibrated space …

Development And Application Of New Methods For Magnetic Resonance Elastography Of The Brain, Charlotte Anne Guertler

McKelvey School of Engineering Graduate Student Theses & Dissertations

Accurate mechanical properties of the intact, living brain are essential for modeling traumatic brain injury (TBI). However, the properties of brain tissue in vivo have traditionally been measured in ex vivo samples. Magnetic resonance elastography (MRE) can be used to measure motion and estimate material properties of soft tissues in vivo, but MRE typically assumes tissue isotropy and homogeneity. The objective of this thesis is to improve MRE of soft tissue, like the brain, by developing and evaluating methods for in vivo estimation of heterogeneous, anisotropic properties. This was achieved through pursuit of the following aims: (1) quantifying the differences …

The Effects Of Anterior Cruciate Ligament Thickness, Knee Joint Laxity, Activity Level, Neuromuscular Imbalances And Lower Extremity Muscular Activation Patterns On Anterior Cruciate Ligament Loading, Zachary A. Sievert

Human Movement Studies & Special Education Theses & Dissertations

There are numerous known mechanisms of anterior cruciate ligament (ACL) injury risk that span from knee joint laxity to landing mechanics. However, the relationship of these mechanisms to ACL loading during landing is unclear. In addition to landing mechanics, anthropological aspects such as ACL diameter, which can now be obtained via ultrasound, may also be an important mechanism for ACL loading. However, the relationship between ACL diameter to ACL loading and landing mechanics remains unknown. This study was conducted with three primary purposes. The first purpose of this study was to examine the inter and intra-rater reliability of using ultrasound …

The Influence Of Strength In Load-Velocity Relationships In The Back Squat, Thaddeus Light

Electronic Theses and Dissertations

Load-velocity relationships may vary between people of different strength levels and across different loads. The purpose of this dissertation was to investigate how external loads influence the velocity characteristics of the back squat exercise, and the influence of strength on these variables. Healthy male students with a history of resistance training completed repetitions at specified intensities of their estimated one-repetition maximum (1RM) until they reached 1RM. Back squat 3D motion analysis was captured using four Vicon T010 cameras (Vicon Motion Systems Ltd.; Oxford, UK) and Vicon Nexus 1.8.5 software. Data were transported into R custom coding statistical analysis software (version …

Barbell Trajectory And Kinematics During Two International Weightlifting Championships, Aaron J. Cunanan

Electronic Theses and Dissertations

Several methods have been used in the scientific literature to study the weightlifting pull. Broadly, these methods are used to measure kinematic or kinetic variables exhibited by the lifter, the barbell, or the lifter-barbell system. However, there is an apparent disconnect between weightlifting research and coaching practice that may reduce the perceived benefits of technique analysis among coaches and present some challenges for coaches who seek to incorporate technique analysis into their coaching practice. Differences and trends in the technique of competitive weightlifting performances are apparent from the available literature. However, there are also gaps in the literature due to …

Locomotor Patterns Change Over Time During Walking On An Uneven Surface, Jenny A. Kent, Joel H. Sommerfeld, Mukul Mukherjee, Kota Z. Takahashi, Nicholas Stergiou

Journal Articles

During walking, uneven surfaces impose new demands for controlling balance and forward progression at each step. It is unknown to what extent walking may be refined given an amount of stride-to-stride unpredictability at the distal level. Here, we explored the effects of an uneven terrain surface on whole-body locomotor dynamics immediately following exposure and after a familiarization period. Eleven young, unimpaired adults walked for 12 min on flat and uneven terrain treadmills. The whole-body center of mass excursion range (COM_exc) and peak velocity (COM_vel), step length and width were estimated. On first exposure to uneven terrain, …

Clinging In Plethodontid Salamanders, Mary Kathleen O'Donnell

USF Tampa Graduate Theses and Dissertations

The ability to cling to and climb on inclined, vertical, and inverted surfaces gives animals access to additional shelter and food and may provide refuge from unsuitable temperature and moisture conditions or escape from ground-dwelling predators. Salamanders have been shown to cling to surfaces and engage in climbing behavior, but their maximum clinging capability and mechanisms of attachment are not well understood. While some arboreal salamanders possess prehensile tails, salamanders lack many morphological adaptations for attachment, such as claws, toe pads, and fibrillar adhesive pads. Maximum cling performance and surface area of attachment were measured, and the adhesive capability of …

Using A Mobile Application To Assess Knee Valgus In Healthy And Post-Anterior Cruciate Ligament Reconstruction Participants, Kai-Yu Ho, Brenda Benson Deaver, Tyrel Nelson, Catherine Turner

Physical Therapy Faculty Research

Context: Popularity of using handheld devices in clinical settings has increased, especially the use of motion analysis applications (MAAs). Video-based measurement tools have been found reliable in measuring knee valgus in subjects without anterior cruciate ligament (ACL) injury. However, there is a need for validation of using a MAA to measure knee valgus in an injured population, given that they may exhibit higher degrees of knee valgus. Objective: To examine the reliability and validity of using a MAA to measure knee valgus during functional activities used to assess return to sport after ACL reconstruction (ACLR). Design: Reliability and validity study. …

The Foot And Ankle Structures Reveal Emergent Properties Analogous To Passive Springs During Human Walking, Erica Hedrick, Steven J. Stanhope, Kota Z. Takahashi

Journal Articles

An objective understanding of human foot and ankle function can drive innovations of bio-inspired wearable devices. Specifically, knowledge regarding how mechanical force and work are produced within the human foot-ankle structures can help determine what type of materials or components are required to engineer devices. In this study, we characterized the combined functions of the foot and ankle structures during walking by synthesizing the total force, displacement, and work profiles from structures distal to the shank. Eleven healthy adults walked at four scaled speeds. We quantified the ground reaction force and center-of-pressure displacement in the shank’s coordinate system during stance …

Improved Orthopaedic Repairs Through Mechanically Optimized, Adhesive Biomaterials, Stephen Wheeler Linderman

McKelvey School of Engineering Graduate Student Theses & Dissertations

Despite countless surgical advances over the last several decades refining surgical approaches, repair techniques, and tools to treat tendon and tendon-to-bone injuries, we are still left with repair solutions that rely on fairly crude underlying mechanical principles. Musculoskeletal soft tissues have evolved to transfer high loads by optimizing stress distribution profiles across the tissue at each length scale. However, instead of mimicking these natural load transfer mechanisms, conventional suture approaches are limited by high load transfer across only a small number of anchor points within tissue. This leads to stress concentrations at anchor points that often cause repair failure as …
