Interactive Effects Of Tissue Temperature And Hydration State On Tendon Mechanical Properties Using A Chicken Drumstick Model, Makayla Maso, Kiara Maso, Mikayla Hulvey

Discovery Day - Daytona Beach

This study focused on the effects of temperature and hydration on tendon extensibility. Four experimental groups were tested using chicken leg tendons tested ex vivo: cold and dehydrated, cold and hydrated, warm and dehydrated, and warm and hydrated. Each treatment group was pulled with an increasing load and measured. It was hypothesized that the warm and hydrated test group would extend the furthest. This was based on studies citing increased bodily flexibility with increasing body temperature as well as stiffness at lower temperatures. Combining temperature and hydration state allowed for not only individual effects of variables to be tested but …

A Geometric Morphometric Analysis Of Acetabular Shape Variation Across Bat Families, Jordan L. Huff

Electronic Theses and Dissertations

Bats are the only mammals capable of powered flight, and research is concentrated on this adaptation. Their non-flight locomotion has received comparatively little attention. Previous studies show that non-flight locomotor behaviors vary across families. Members of Pteropodidae are efficient climbers but cannot effectively walk, whereas Phyllostomidae and Vespertilionidae are better at terrestrial locomotion but show reduced arboreal capabilities. The non-flight locomotion of Hipposideridae and Rhinolophidae is less understood, although rhinolophids exhibit limited terrestrial locomotion. This study examined whether differences in locomotor behavior are associated with variation in acetabular morphology. A geometric morphometric analysis of acetabular shape was conducted across multiple …

Living With Confidence: The Importance Of Hip Health, Ellisa Louisy, Shannon M. Meyer, Kyle W. Reason

InnovateHER Meeting 2026

The hip joint is essential for weight-bearing movement, providing both mobility and stability as a ball-and-socket joint. Surrounding muscles generate movement and maintain stability during daily activities like walking, standing, and rising from a chair. As the link between the trunk and lower limbs, reduced hip strength or mobility can impair balance and movement efficiency. In women, hormonal changes, especially after menopause, contribute to decreased bone density and muscle mass, increasing the risk of osteoporosis and hip fractures and underscoring the importance of hip health.

Hip Stretching Protocol's Impact On Female Ice Hockey Players, Cienna Clark

InnovateHER Meeting 2026

Women’s ice hockey participation continues to grow as do injury rates among these players. However, female ice hockey players often show different injuries than male players. This is largely due to the lack of checking in women’s hockey, which means the injuries that tend to be seen are more about overuse injuries and less catastrophic injuries. Female injuries also tend to be more in their hips, which begs the question: what would happen if hips were stretched on a regular basis? Would these injuries subside, or at least improve?

Lifestyle And Activity Patterns Of The Classic Period Maya From Chac Balam And San Juan, Ambergris Caye, Belize, Abigail L. Hornbeck

Honors Theses

Bioarchaeological research often uses skeletal remains to reconstruct patterns of activity and labor in past populations. This study examines potential sex-based differences in long bone morphology among individuals from the Classic Maya sites of Chac Balam and San Juan on Ambergris Caye, Belize. These coastal communities participated in maritime trade networks, and daily activities such as cargo transport, canoe travel, and fishing may have placed distinctive mechanical stresses on the skeleton. The goal of this study was to evaluate whether measurable differences in bone structure between males and females reflect differences in habitual activity patterns.

Two complementary methods were used …

Comparative Analysis Of Antegrade And Retrograde Nailing For Proximal, Shaft, And Distal Femur Fractures, Saahil Noupada

Rowan-Virtua Research Day

Background:

Antegrade and retrograde intramedullary nailing are widely used for femoral fractures, yet their relative advantages across fracture locations remain debated. This study compares union rates, time to union, malunion, and functional outcomes between approaches, stratified by AO/OTA classification.

Methods:

A systematic review of PubMed, Embase, Cochrane Library, Web of Science, and Scopus (2015 to 2025) was performed. Studies reporting outcomes of antegrade and/or retrograde nailing for proximal (31), diaphyseal (32), and distal (33) femoral fractures were included. Data on demographics, fracture classification, fixation method, and outcomes were extracted. Risk of bias was assessed using ROBINS-I. Pooled estimates were calculated …

Masters Theses/Capstone Projects

ABSTRACT

A CASE COMPARISON OF VO₂MAX AND LOWER EXTREMITY INJURY IN COLLEGIATE WRESTLERS

Kole Jacob Kendall

Otterbein University

Westerville, OH

The purpose of this study was to examine the relationship between preseason aerobic capacity (VO₂max) and lower extremity injury prevalence in Division III collegiate wrestlers. In this two-participant case comparison, Participant 2 sustained a lower extremity injury and demonstrated the lower VO₂max value (37.5 mL·kg⁻¹·min⁻¹), whereas Participant 1 remained uninjured and demonstrated the higher VO₂max value (40.8 mL·kg⁻¹·min⁻¹). Although statistical analysis was not feasible because of the limited sample size, this pattern suggests a possible association between lower aerobic capacity …

Play To Win: A Randomized Controlled Trial To Assess The Effects Of Play-Based Training On Upper Extremity Function In Children With Hemiplegia, Vivian London

Honors Scholar Theses

Hemiplegia, or paralysis of one side of the body, is the primary symptom of unilateral cerebral palsy, a subtype of cerebral palsy, the most common movement disorder in children. Standard of care is regular physical and occupational therapy to improve performance in bimanual activities, but conventional therapy can be expensive and draining for caregivers and children, so a need exists for a novel intervention that can take place at home and that is economical for families while being engaging for children. This thesis reports data from a subset of ten children seen as part of a randomized controlled clinical trial …

Biomechanical Effects Of Bilateral Torsion And Skeletal Fusion: A Case Study, Linnéa Forbes

Honors Projects

As part of both a personal endeavor and an academic project, I have investigated the aetiology and treatment of seemingly idiopathic and debilitating leg pain in a patient over the past 10 years. Via collaboration with medical professionals at Cincinnati Children’s Hospital, Cincinnati Premier Physical Therapy, and Cincinnati Women’s TriHealth, I have identified sources of pain at the anatomical level. The combination of internal femoral torsion, external tibial torsion, pes planus, and bony fusions appear to be major perpetuators of the pain. An effective treatment continues to be evasive. To date, I have attempted to find answers through genetic approaches, …

Comparison Of Vibrating And Non-Vibrating Foam Roller On Hamstring Range Of Motion, Rakhoon Sung, Portia B. Resnick, Karen G. Roos, Mimi Nakajima

Clinical Practice in Athletic Training

Tightness in the distal hamstring is a common complaint among active individuals. While a foam roller is used to release muscle tension, there are limited studies about the effect using a vibrating foam roller (VFR) on hamstring flexibility and knee range of motion (ROM). For this reason, the purpose of the research was to compare the effect of a VFR and nonvibrating foam roller (NVFR) on hamstring flexibility and knee ROM in active college students. It was hypothesized that there would be more improvement in hamstring flexibility and knee ROM with a VFR than an NVFR. A randomized controlled trial …

Suture Augmentation With Ucl Repairs In Baseball Pitchers As An Alternate To Reconstructions: An Evidence-To-Practice Review, Kayleigh A. De Koker, Kenneth E. Games

Clinical Practice in Athletic Training

An injury to the ulnar collateral ligament (UCL) is sustained through repetitive valgus motions, increasing in prevalence across all levels of baseball due to the increasing workload demands placed on the medial elbow in pitching. Traditionally, UCL tears have been managed through reconstructions followed by a lengthy rehabilitation process. In recent years, the UCL repair with suture augmentation has gained favor given the enhanced patient and clinician outcomes in return-to-play timelines, decreased medial gapping, improved Kerlan Jobe Orthopedic Clinic (KJOC) scores, and long-term functionality. Utilizing 4 databases (MEDLINE, Embase Cochrane library, Science Direct, and Scopus), literature was obtained addressing the …

Evaluating Forearm Strength Variability In Collegiate Tennis Players Over The Course Of A Competitive Season, Jeffrey Williams, Payton Jensen, Kevin Laudner

Clinical Practice in Athletic Training

The muscles of the forearm undergo routine, forceful, and repetitive contractions while playing tennis and may experience adaptive changes that can precede injury. An understanding of forearm strength profiles of tennis players following a competitive season would assist clinicians’ evidence-based management of the forearm’s readiness for training, competition, and return-to-sport participation. Therefore, the purpose of this study was to explore the effects of a competitive tennis season on forearm strength among collegiate tennis athletes.
