Comparison Of A Dynamic Ankle Orthosis To A Walking Boot For Preserving Ankle Joint Motion And Reducing Tibial Bone Load And Strain, Perri Johnson Jr. 2022 University of Tennessee Health Science Center

Comparison Of A Dynamic Ankle Orthosis To A Walking Boot For Preserving Ankle Joint Motion And Reducing Tibial Bone Load And Strain, Perri Johnson Jr.

Theses and Dissertations (ETD)

Tibial stress fractures are a common overuse injury accounting for 21.9 – 69% of stress fractures among runners and 24 – 51.2% of stress fractures in military cadets. Current treatment involves wearing a walking boot for 3 – 12 weeks, which limits ankle motion and causes lower limb muscle atrophy. A Dynamic Ankle Orthosis (DAO) provided a distractive force that offloaded the ankle and retained sagittal ankle excursion during walking. It remains unclear how tibial loading is affected by a walking boot or the DAO. This thesis presents a feasibility study confirming the offloading effects of the DAO on tibial …

Collapsible Prosthetic Shower Leg, Amanuel Matias, Mahsa Ebrahim 2021 Loyola Marymount University

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. …


Comparative Gait Analysis Of Transtibial Amputees Versus, Charlotte Vitale 2021 University of Rhode Island

Comparative Gait Analysis Of Transtibial Amputees Versus, Charlotte Vitale

Senior Honors Projects

While individuals with lower limb prosthetics make up a very small percentage of the population, their musculoskeletal deformities impair their abilities to produce “normal” biomechanical actions. The deviations in their walking patterns can further inhibit their efficacy in other activities of basic living. Understanding the distinct kinematic comparisons during gait between lower limb amputees and able-bodied individuals is critical for those planning to enter such a field of study working with this specific population. As an aspiring specialized Physical Therapist, it is very likely that I will be assisting clients to regain a healthy walking pattern after a traumatic accident, …

Comparison Of Machine Learning Models: Gesture Recognition Using A Multimodal Wrist Orthosis For Tetraplegics, Charlie Martin 2020 Purdue University

Comparison Of Machine Learning Models: Gesture Recognition Using A Multimodal Wrist Orthosis For Tetraplegics, Charlie Martin

The Journal of Purdue Undergraduate Research

Many tetraplegics must wear wrist braces to support paralyzed wrists and hands. However, current wrist orthoses have limited functionality to assist a person’s ability to perform typical activities of daily living other than a small pocket to hold utensils. To enhance the functionality of wrist orthoses, gesture recognition technology can be applied to control mechatronic tools attached to a novel fabricated wrist brace. Gesture recognition is a growing technology for providing touchless human-computer interaction that can be particularly useful for tetraplegics with limited upper-extremity mobility. In this study, three gesture recognition models were compared—two dynamic time-warping models and a hidden …

Effect Of Unilateral Lower-Limb Amputation On Intact Limb Biomechanics: A Systematic Review, Amanda Boyd

Master's Theses

The United States will perform 30,000-40,000 amputations this year (Ertl et al., 2019). As a common medical intervention, there is extensive research regarding rehabilitation strategies and post-operative care. Many studies have explored the effects of the affected limb and prosthetic intervention yet have neglected that of the contralateral limb (De Asha et al., 2014; Jones et al., 2006; Winter & Sienko, 1988). Studies have reported an increase in secondary musculoskeletal conditions among unilateral lower-limb amputees, particularly in the intact limb, indicating the need for additional research (Gailey et al., 2008). The purpose of this systematic review was to investigate the …

Upper Limb Rehabilitation For Amputees, Michaela Ramandanes 2020 Marymount University

Upper Limb Rehabilitation For Amputees, Michaela Ramandanes

Virginias Collegiate Honors Council Conference

It is estimated that 75% of the 30 million people that need prosthetic devices lack access to the technologies they need. This suggests a need for solutions outside of standard healthcare models. In this work we present a solution by development of a simple, safe and accessible at-home exercise program for individuals with upper limb loss. It is intended to help amputees strengthen the muscles needed to operate body-powered prostheses when muscles have atrophied from lack of use. Extensive research identified the most effective exercises to hinder overuse injuries. The exercises were compiled and published on a website with a …


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 2020 Kennesaw State University

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 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 …


Abduction Contractures Within Infants With Developmental Dysplasia Of The Hip, Nathan Stanton 2020 Embry-Riddle Aeronautical University

Abduction Contractures Within Infants With Developmental Dysplasia Of The Hip, Nathan Stanton

Doctoral Dissertations and Master's Theses

Developmental Dysplasia of the hip is a condition that affects 1 to 3 of every 1000 infants born globally. It is a pathology that involves the instability, subluxation, or dislocation of the femoral head from the acetabulum. Through a rating system by the International Hip Dysplasia Institute or Graf System, hips are rated based on their level of instability or dislocation and the infant is then prescribed a treatment. While Finite element models of dysplastic hips have been developed previously, a study that seeks to understand the contribution of an abduction contracture of the hip has yet to be performed. …
