Hip Mechanics Of Unilateral Drop Landings, Bobbie S. Irmischer

Human Movement Studies & Special Education Theses & Dissertations

Increased hip forces are a proposed factor for osteoarthritis and femoroacetabular impingement. These forces can be estimated through musculoskeletal modeling using measured kinematics and kinetics. An understanding of hip joint loading during landing in a asymptomatic population will begin to elucidate what, if any, sex differences exist and how changes in landing condition alter hip mechanics. The overall purpose of this dissertation was to explore how sex and landing condition effect landing mechanics. Landing mechanics were quantified using ground reaction forces (GRF), hip joint forces (HJF), and lower extremity kinematics during unilateral drop landings from 30-cm, 40-cm, and 50-cm, as …

Varying Negative Work Assistance At The Ankle With A Soft Exosuit During Loaded Walking, Philippe Malcolm, Sangjun Lee, Simon Crea, Christopher Siviy, Fabricio Saucedo, Ignacio Galiana, Fausto A. Panizzolo, Kenneth G. Holt, Conor J. Walsh

Journal Articles

Background: Only very recently, studies have shown that it is possible to reduce the metabolic rate of unloaded and loaded walking using robotic ankle exoskeletons. Some studies obtained this result by means of high positive work assistance while others combined negative and positive work assistance. There is no consensus about the isolated contribution of negative work assistance. Therefore, the aim of the present study is to examine the effect of varying negative work assistance at the ankle joint while maintaining a fixed level of positive work assistance with a multi-articular soft exosuit.

Methods: We tested eight participants during …

Gait Deficiencies Associated With Peripheral Artery Disease Are Different Than Chronic Obstructive Pulmonary Disease, John D. Mccamley, Eric J. Pisciotta, Jennifer M. Yentes, Shane R. Wurdeman, Stephen I. Rennard, Iraklis I. Pipinos, Jason M. Johanning, Sara A. Myers

Journal Articles

Objective: Previous studies have indicated that patients with peripheral artery disease (PAD), display significant differences in their kinetic and kinematic gait characteristics when compared to healthy, aged-matched controls. The ability of patients with chronic obstructive pulmonary disease (COPD) to ambulate is also limited. These limitations are likely due to pathology-driven muscle morphology and physiology alterations establish in PAD and COP, respectively. Gait changes in PAD were compared to gait changes due to COPD to further understand how altered limb muscle due to disease can alter walking patterns. Both groups were independently compared to healthy controls. It was hypothesized that both …

Muscle Strength And Control Characteristics Are Altered By Peripheral Artery Disease, Molly Schieber, Ryan Hasenkamp, Iraklis Pipinos, Jason Johanning, Nicholas Stergiou, Holly Despiegelaere, Jung Chien, Sara Myers

Journal Articles

Objective

Peripheral artery disease (PAD), a common manifestation of atherosclerosis, is characterized by lower leg ischemia and myopathy in association with leg dysfunction. Patients with PAD have impaired gait from the first step they take with consistent defects in the movement around the ankle joint, especially in plantar flexion. Our goal was to develop muscle strength profiles to better understand the problems in motor control responsible for the walking impairment in patients with PAD.

Methods

Ninety-four claudicating PAD patients performed maximal isometric plantar flexion contractions lasting 10 seconds in two conditions: pain free (patient is well rested and has …

Posture And Gaze Tracking Of A Vertically Moving Target Reveals Age-Related Constraints In Visuo-Motor Coupling, Haralampos Sotirakis, Anastasia Kyvelidou, Nicholas Stergiou, Vassilia Hatzitaki

Journal Articles

Previously we have demonstrated that the effect of aging on posture and gaze active tracking of a visual target moving in the horizontal direction is dependent on target’s complexity. In this study, we asked whether a similar phenomenon is present when tracking a visual target moving with varying complexity in the vertical direction. Ten young (22.98 ± 2.9 years) and 10 older adults (72.45 ± 4.72 years) tracked for 120 s, a visual target moving vertically by shifting their bodyweight in the anterior-posterior direction. Three target motions were tested: a simple periodic (sine wave), a more complex (Lorenz attractor) and …

The Interaction Of Scale And Temperature In Elastically Powered Movements, Jeffrey P. Olberding

USF Tampa Graduate Theses and Dissertations

For many animals, rapid movements place high power demands on underlying muscles. Storage of muscle energy in elastic structures and the subsequent rapid release of that energy can effectively amplify muscle power. Elastic recoil can also confer thermal robustness to performance in behaviors occurring at variable temperatures. Muscle contractile performance tends to decrease at lower temperatures, but elastic recoil is less affected by temperature. Here I examine the impacts of temperature and scale in systems using elastic recoil and I explore possible interactive effects on movement performance.

I explored the role that muscle contractile properties play in the differences in …

Functional Trade-Offs In Feeding Performance In Salamanders Of The Family Salamandridae, Charlotte M. Stinson

USF Tampa Graduate Theses and Dissertations

Performance is an organism’s ability to accomplish a particular task or behavior, and morphology can have a major impact on the performance of an organism. Salamanders are ecologically diverse and can feed using a variety of behaviors depending on the environment in which feeding occurs. Feeding is accomplished through the use of the hyobranchial apparatus, which lies along the oropharynx, and this structure can have competing roles; in aquatic environments the apparatus is used for suction feeding and works to depress the floor of the mouth, but during terrestrial feeding this structure projects the tongue forward out of the mouth. …

The Development Of A Platform Interface With The Use Of Virtual Reality To Enhance Upper-Extremity Prosthetic Training And Rehabilitation, Ashley D. Knight

USF Tampa Graduate Theses and Dissertations

This dissertation focuses on the investigation and development of an effective prosthetic training and rehabilitation platform with the use of virtual reality to facilitate an effective process to return amputees to the highest level of independence and functioning possible.

It has been reported that approximately 10 million people live with a limb loss worldwide, with around 30% being an upper-extremity amputee. The sudden loss of a hand or arm causes the loss of fine, coordinated movements, reduced joint range of motion (ROM), proprioceptive feedback and aesthetic appearance, all which can be improved with the use of a prosthesis and proper …

Body Size Regulation Via Bmp Signaling In Caenorhabditis Elegans, Uday Madaan

Dissertations, Theses, and Capstone Projects

The body size of an organism can be a crucial determinant of access to nutrition, reproductive success and overall survival in the wild. However, how body size of an individual is determined is incompletely understood. Body size is a complex trait determined by multiple pathways and genes, making it difficult to understand the role of individual genes and pathways in determining overall size. In Caenorhabditis elegans, a homolog of Bone Morphogenetic Proteins (BMP) is a major regulator of body size; functional loss of DBL-1 leads to a small body size. Due to a drastic change in body size in dbl-1 …

Differences In Lower Limb Kinetics In College Age Female Gymnasts To Coaches’ Perceived Efficiency In A Specific Counter Movement Jump Technique, Stephen Christopher Avgerinos

Theses and Dissertations

This thesis reports the results of a quantitative research project which examined kinetics of female collegiate gymnasts aged 18 to 21 performing a ‘punching’ counter-movement jump (CMJ) technique that is taught and required for exemplar scoring during NCAA competition. Twelve female gymnasts were recruited from the competitive team at Illinois State University. Participation was voluntary and athletes were not compensated. Each gymnast performed 8 punch-CMJ trials without coaching instruction except to perform a punching CMJ. The method of performing this CMJ began by stepping off from a 33 cm elevation, ‘punching’ off the force plates, and finishing with a landing …
