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
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 ...
Effect Of Unilateral Lower-Limb Amputation On Intact Limb Biomechanics: A Systematic Review, 2020 The University of Southern Mississippi
Effect Of Unilateral Lower-Limb Amputation On Intact Limb Biomechanics: A Systematic Review, Amanda Boyd
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 ...

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 ...
Upper Limb Rehabilitation For Amputees, 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 ...
Abduction Contractures Within Infants With Developmental Dysplasia Of The Hip, 2020 Embry-Riddle Aeronautical University
Abduction Contractures Within Infants With Developmental Dysplasia Of The Hip, Nathan Stanton
PhD 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 ...

A Computational Biomechanical Model-Based Optimization Of Fulcrum Support In Orthosis Enabled Closed Reduction Of Developmental Dysplasia Of The Hip, Christopher Rose
Electronic Theses and Dissertations, 2020-
Hip abduction orthosis devices (HAOD) are used to reduce the hip joint of infants affected by developmental dysplasia of the hip (DDH). HAOD have been successful for mild cases of DDH and ineffective for severe cases. Efforts in understanding the biomechanics of lower limbs have been made to improve the success rate of current treatment methods, especially for Grade IV dislocations (G4). The aim of this dissertation is twofold: first, it proposes the use of a varying fulcrum point (FP) located below the leg to improve DDH treatment; and secondly, it defines the optimal FP (OP) location for a broad ...

Impact Of Footwear On Mechanisms Of Knee Osteoarthritis Progression, 2019 University of Massachusetts Amherst
Impact Of Footwear On Mechanisms Of Knee Osteoarthritis Progression, Ethan Steiner
Knee osteoarthritis (OA) is a debilitating disease affecting the entire knee joint by inducing pathological changes to the cartilage and menisci. Currently, the etiology of OA is not completely understood. However, altered gait mechanics, specifically increased joint loading, of OA patients have a clear association with both symptomatic and structural OA progression. Non-surgical intervention tools, such as variable stiffness shoes (VSS), have been developed as a way to decrease loading within the knee joint. However, with external moments being surrogate measures for knee loading, it is unclear if changes in knee moments with the footwear are sufficient to result in ...
Improving 3d Printed Prosthetics With Sensors And Motors, 2019 Bridgewater College
Improving 3d Printed Prosthetics With Sensors And Motors, Rachel Zarin
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 ...
Psychometric Properties Of Standardized Balance Confidence, Fear Of Falling, And Falls-Efficacy Measures In People With Lower Limb Amputations, Jack Y. Wang, Susan W. Hunter, Ricardo Viana, Jeffrey D. Holmes, Michael Payne
Western Research Forum
In Canada, >50% of community-dwelling lower limb amputees (LLA) fall at least once each year, a rate that is almost twice that of community-dwelling older adults. While the physical consequences of falls may be readily apparent, psychological sequelae that follow may be just as, if not more, detrimental than an actual fall itself. Current measures of balance confidence show no change in LLA following discharge from rehabilitation. The limited detectable change may be due to content validity challenges of the measures as they were not developed for the unique challenges faced by LLA.
1) Review items from standardized ...

Investigation Of Characteristic Rippling Topology Produced During Uhmwpe Sliding, 2019 Oklahoma Christian University
Investigation Of Characteristic Rippling Topology Produced During Uhmwpe Sliding, Kevin G. Plumlee, Christian J. Schwartz
Mechanical Engineering Publications
Ultra-high molecular weight polyethylene (UHMWPE) remains the sole polymer bearing material for use in orthopedic implants and its behavior has been studied extensively. Various techniques, such as crosslinking, have been employed to reduce the total wear volume. However, little is known about the actual wear mechanisms that contribute to the removal of debris from the bulk. A nearly universal observation of the wear surfaces after multidirectional sliding of UHMWPE is the presence of regularly-spaced parallel ripples whose wavelength closely matches debris size. In spite of the fact that this phenomenon has been observed for decades in both retrieved implants as ...
