Biomechanical Comparison Of The Validity Of Two Configurations Of Simulators For Body-Powered Hand Prostheses, Camille Bennett, Amanuel Matias, Brendan Smith, Jenevieve Roper, Stephen Estelle
Biomechanical Comparison Of The Validity Of Two Configurations Of Simulators For Body-Powered Hand Prostheses, Camille Bennett, Amanuel Matias, Brendan Smith, Jenevieve Roper, Stephen Estelle
Honors Thesis
Simulators are often used in prosthesis research to evaluate new devices or characterize aspects of prosthesis use, so as to recruit participants without amputations. Simulators, in general, must locate the prosthesis somewhere other than where the intact biological limb exists. In this study, we compared two configurations of simulators for hand prostheses to determine which leads to more natural elbow and shoulder kinematics, and in turn, which is the more valid simulator. One configuration located the prosthesis in-line with the forearm, beyond the biological hand; the other located it beside the hand. We measured the kinematics of 12 non-amputee participants …
A Comprehensive Analysis Of Balance, Symmetry, And Center Of Mass In The Gait Cycle Of Transfemoral Amputees, Kayla T. Etienne
A Comprehensive Analysis Of Balance, Symmetry, And Center Of Mass In The Gait Cycle Of Transfemoral Amputees, Kayla T. Etienne
FIU Electronic Theses and Dissertations
The purpose of this thesis is to create a framework that assists in the transfemoral prosthesis fitting process by calculating balance and symmetry to quantify patient comfort with an understanding of bipedal locomotion and human anatomy. Three different software applications were used to compare (1) the body position during gait cycle, (2) the natural and amputee anatomies, (3) the natural and prosthetic legs, and (4) the equilibrium and torque movements of the hip, knee, and ankle joints. Models were created in Maya for analysis in Solidworks and MEL code evaluation with MatLab. The MatLab code tested combinations of joint degrees …
3d Parametric Hand To Improve Prosthetic Hand Functionality, Maria C. Gerardi
3d Parametric Hand To Improve Prosthetic Hand Functionality, Maria C. Gerardi
UNLV Theses, Dissertations, Professional Papers, and Capstones
The use of prosthetics can significantly enhance an individual’s standard of living, not only offering functional advantages but psychological advantages as well. Unfortunately for children with upper limb reduction, options are limited and rejection rates are high due to a multitude of reasons including discomfort and poor functionality. This study proposes a new parametric 3D design model (Parametric Hand) with an adjustable thumb that can be easily manipulated to the uniqueness of an individual. The Parametric Hand was evaluated, both qualitatively and quantitatively, against the Flexy-Hand 2, a commonly used prosthetic hand. The results showed insignificant differences in all testing …
Contemporary Leadership Theory In Biomedical Engineering, Anna Seifried
Contemporary Leadership Theory In Biomedical Engineering, Anna Seifried
Senior Honors Projects
Modern leadership theories have begun to slowly weave their way into technical skill based fields, such as Biomedical Engineering, due to a critical need for effective communication skills.
Effectively and efficiently integrating contemporary leadership techniques into these industries, allows for clear goal setting and increased personal and professional satisfaction for both the customers and faculty.
For my Honors Project, I sought to find pre-existing connections and form new ones between modern leadership theories and the current Biomedical Engineering field. I focused specifically on Prosthetics and Orthopedics, but these theories can be applied to other branches of Biomedical Engineering and extend …

Walking Kinematics In Young Children With Limb Loss Using Early Versus Traditional Prosthetic Knee Prescription Protocols, Mark Daniel Geil, Zahra Safaeepour, Brian Giavedoni, Colleen Coulter
Faculty and Research Publications
The traditional treatment protocol for young children with congenital or acquired amputations at or proximal to the knee prescribes a prosthesis without a working knee joint, based in part on the assumption that a child learning to walk cannot properly utilize a passively flexing prosthetic knee component. An alternative to this Traditional Knee (TK) protocol is an “Early Knee” (EK) protocol, which prescribes an articulating prosthetic knee in the child’s first prosthesis, during development of crawling and transitioning into and out of upright positions. To date, no study has compared samples of children with limb loss at or proximal to …

Hybrid Electro-Plasmonic Stimulation Of Primary Neurons, Ratka Damnjanovic
USF Tampa Graduate Theses and Dissertations
Biomedical prosthetics utilizing electrical stimulation have limited, effective spatial resolution due to spread of electrical currents to surrounding tissue, causing nonselective stimulation. So, precise spatial resolution is not possible for traditional neural prosthetic devices, such as cochlear implants. More recently, alternative methods utilize optical stimulation, mainly infrared, sometimes paired with nanotechnology for stimulating action potentials, which has its own drawbacks, as it may heat surrounding tissue. Recently, we employed plasmonic stimulation methods utilizing gold nanoparticle-coated nanoelectrodes to convert visible light pulses into localized surface plasmon resonance transduction for stimulation of electrically excitable cells, which had limited success. Here, we report …
Enhanced Surface Electrical Neurostimulation (Esens): A Non-Invasive Platform For Peripheral Neuromodulation, Andres Eduardo Pena
Enhanced Surface Electrical Neurostimulation (Esens): A Non-Invasive Platform For Peripheral Neuromodulation, Andres Eduardo Pena
FIU Electronic Theses and Dissertations
Electrical stimulation of peripheral afferents has been used to study the sensory neural code and restore lost sensory function after amputation. Recently, implantable neural interfaces have prompted multiple breakthroughs in artificial somatosensory feedback for individuals with amputation, resulting in functional and psychological benefits. Although promising, the invasive nature of these approaches limits wide clinical applications, hindering the development of advanced neuromodulation strategies for intuitive sensory feedback. Transcutaneous (surface) stimulation is a potential non-invasive alternative. However, traditional surface stimulation methods are hampered by inadequate electrode and stimulation parameter fitting, localized discomfort, poor selectivity, and limited percept modulation.
An enhanced surface electrical …
