Functional Movement Patterns And Perceived Mobility In Collegiate Lacrosse Athletes, Christopher J. Rosenborough

Student Scholar Showcase

Context: The stress on the body from sport participation may play a role in an athlete’s ability to function throughout a season. The primary objective of this study was to examine the effects of a non-traditional lacrosse fall season on functional movement patterns for both males and females. Our second objective was to observe how collegiate lacrosse athletes perceived mobility.

Methods: Fifty males (age=19.38+1.24 years, height=182.63+6.16 cm, mass=82.37+8.46 kg) and 22 females (age=19.68+1.17 years, height=165.10+6.88 cm, mass=64.09+8.72 kg) who participated on National Collegiate Athletic Association Division III lacrosse teams volunteered to participate. Independent variable was time (pre, post). …

The Perception Of Head Impacts Sustained By Collegiate Baseball Catchers: A Pilot Study, Caleb Johnston

Student Scholar Showcase

Repetitive subconcussive head impacts have been studied in a variety of contact sports and have been found to impair performance in football, soccer, hockey, and lacrosse athletes. To our knowledge no one has investigated the frequency of head impacts in the sport of collegiate baseball. To date, athlete perceived number of head impacts and actual head impacts recorded during participation have not been compared. A sample of 3 baseball catchers from one National Collegiate Athletic Association (NCAA) Division III baseball team were studied.Our results indicated perceived game impacts did not differ from actual game impacts (t₂=1.76, P=.23; …

The Effects Of Stiffness Of A Prosthetic Shock-Absorbing Pylon On Mechanical Work During Walking, Jenny Anne Maun

Title: The effects of stiffness of a prosthetic shock-absorbing pylon on mechanical work during walking

Degree: Masters

Faculty Advisor: Kota Z. Takahashi, PhD

Co-authors: Steven A. Gard, PhD; Matthew J. Major, PhD

A prosthetic shock-absorbing pylon (SAP) is intended to attenuate impact forces, provide comfort, and reduce residual limb pain for prosthesis users. However, the effect of an SAP and its spring stiffness on the mechanical work done by the prosthetic limb during walking remains unclear. The purpose of this study: to investigate the effects of SAP spring stiffness and walking speed on the mechanical work …

How Prosthetic Ankle Stiffness & Load Carriage Affect Metabolic Energy Expenditure During Walking, Erica A. Hedrick, Philippe Malcolm, Jason M. Wilken, Kota Z. Takahashi

UNO Student Research and Creative Activity Fair

The ankle structures play a key role in body support, forward propulsion and leg swing. One important property of the human ankle is its ‘quasi-stiffness’, or resistance to angular motion. The ankle joint stiffness can play a role in aiding the lower leg as its rocks over the foot. Human biological ankle stiffness changes in response to changes in the mechanical demands of walking (e.g. added load or changes in speed), using active muscle contractions. However, the role of ankle stiffness in regulating metabolic energy across walking conditions is unknown. Therefore, the purpose of this study is to determine how …

3D Prosthetics Effects on Standing Posture in Unilateral Upper Limb Deficient Children

Keaton Young

Department of Biomechanics, University of Nebraska at Omaha

Introduction

Upper Limb Reduction Deficiency (ULD) is a congenital disability that affects the upper limb, which the Center for Disease Control and Prevention estimates that nearly 1,500 babies are born with ULD in the United States yearly ^1,2. Prior research has focused on functional treatment of the upper limbs but has lacked observance of the effects that prosthetics and limb loss incur to the trunk. Therefore, the purpose of this study is to examine the acute effects …
