Assessment Of Knee Flexion In Young Children With Prosthetic Knee Components Using Dynamic Time Warping, Mark Daniel Geil, Zahra Safaeepour
Assessment Of Knee Flexion In Young Children With Prosthetic Knee Components Using Dynamic Time Warping, Mark Daniel Geil, Zahra Safaeepour
Faculty and Research Publications
Introduction: Analysis of human locomotion is challenged by limitations in traditional numerical and statistical methods as applied to continuous timeseries data. This challenge particularly affects understanding of how close limb prostheses are to mimicking anatomical motion. This study was the first to apply a technique called Dynamic Time Warping to measure the biomimesis of prosthetic knee motion in young children and addressed the following research questions: Is a combined dynamic time warping/root mean square analysis feasible for analyzing pediatric lower limb kinematics? When provided at an earlier age than traditional protocols dictate, can children with limb loss utilize an articulating …
Collapsible Prosthetic Shower Leg, Amanuel Matias, Mahsa Ebrahim
Collapsible Prosthetic Shower Leg, Amanuel Matias, Mahsa Ebrahim
Honors Thesis
The purpose of this capstone project is to build a collapsible prosthetic shower leg that can provide a transtibial amputee with reliable support while showering. Phil Tamoush, an 83-year old transtibial amputee, was the inspiration for this work. Phil’s constant travel for his arbitration work leaves him without the option to bring along his usual shower leg due to the additional space it takes up in his travel bag. There are currently no commercially available prosthetic shower legs that can collapse into a condensed unit, so this capstone project explores an unexplored field for which there is a significant need. …
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 …
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
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
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 …
How Degrees Of Freedom Affects Sense Of Agency, Akima Connelly, Jungsu Pak, Tian Lan, Uri Maoz
How Degrees Of Freedom Affects Sense Of Agency, Akima Connelly, Jungsu Pak, Tian Lan, Uri Maoz
Student Scholar Symposium Abstracts and Posters
Can the rubber-hand illusion be extended to a moving robotic arm in different degrees of freedom (DOF), inducing sense of ownership & agency over the arm? We hypothesize that DOF closer to what humans possess will result in a stronger sense of ownership and agency.
Improving 3d Printed Prosthetics With Sensors And Motors, Rachel Zarin
Improving 3d Printed Prosthetics With Sensors And Motors, Rachel Zarin
Honors Projects
A 3D printed hand and arm prosthetic was created from the idea of adding bionic elements while keeping the cost low. It was designed based on existing models, desired functions, and materials available. A tilt sensor keeps the hand level, two motors move the wrist in two different directions, a limit switch signals the fingers to open and close, and another motor helps open and close the fingers. All sensors and motors were built on a circuit board, programmed using an Arduino, and powered by a battery. Other supporting materials include metal brackets, screws, guitar strings, elastic bands, small clamps, …
An Arm And A Leg: Medtech Perspectives On Human-Centered Design, Evan D. Poff
An Arm And A Leg: Medtech Perspectives On Human-Centered Design, Evan D. Poff
Marriott Student Review
The art of human-centered design accounts for both technological and emotional specifications in order to deliver meaningful products that meet the specific needs of the individual customer. Every business professional can deepen his or her understanding of human-centered design – regardless of our industry of choice – by looking to perspectives that the business of medical technology offers. To that end, this article draws upon interviews with three figures in this remarkable field, distilling their insights on how to cultivate businesses that produce human-centered solutions.
Designing Electronics For An Artificial Leg, Taylor Barto
Designing Electronics For An Artificial Leg, Taylor Barto
The Downtown Review
A regenerative prosthesis is modeled and simulated. The simulation is optimized with the biogeography-based optimization algorithm to obtain desired knee angle tracking with a reference knee trajectory and to regenerate energy. The prosthesis is able to track a reference knee angle with a 5.1 degree error averaged over an entire stride and regenerate some energy throughout the stride.

The problem with prosthetics is a longstanding problem that researchers have been working on for many years. They are attempting to create a prosthetic that acts as if it is the original limb or body part. In recent years they have discovered a technology that has assisted many of those who are greatly in need of a prosthetic, such as an amputee or someone who is “locked in”. “Locked in” refers to a person who is technically confined in his own body and has no methods of communication with the world. Brain-computer interface (BCI) has opened up a whole new …
