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 ...
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
Dissertations and 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 ...

Oral Contraceptives As Possible Acl Injury Prevention Method, 2020 Arcadia University
Oral Contraceptives As Possible Acl Injury Prevention Method, Haley Schweizer
Introduction: Anterior Cruciate Ligament (ACL) injuries are an upsetting setback for many athletes that require a long and costly recovery process. The injury rates are four times greater in women than men. Preventative measures that help to prevent ACL injuries are limited to stretching and strengthening. Therefore, this review aims to investigate if oral contraceptive [I] usage provides a possible new avenue for prevention of ACL injury [O] in young female athletes (ages 18-30) [P] compared to those that do not take oral contraceptives [C].
Methods: A literature review was performed though PubMed, Google Scholar, SCOPUS Database, and ClinicalKey ...

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 ...

Obstacle Negotiation And Dual-Tasking In People With A Unilateral Transtibial Amputation., Humberto Omana, Michael Payne, Ricardo Viana, Susan Winnifred Hunter
Western Research Forum
Background: Falls in people with a lower limb amputation (PLLAs) are common and most often occur while walking, resulting in physical and psychological consequences that adversely affect quality of life. Walking is a complex motor task requiring cognitive resources. Due to walking with a prosthesis, PLLAs report focussing on every step they take, indicating greater cognitive needs. However, cognitive resources are limited, and most of our everyday activities also involve the simultaneous performance of motor and cognitive tasks, known as dual-tasking. The inter-relationship between mobility, cognition and postural stability in PLLAs using a prosthesis is just starting to be understood ...

Efficacy Of Assistive Devices Produced With Additive Manufacturing, 2019 University of Nebraska at Omaha
Efficacy Of Assistive Devices Produced With Additive Manufacturing, James Pierce
Student Research and Creative Activity Fair
Despite the frequency of musculoskeletal injuries such as sprains, broken bones and torn ligaments1, treatment options are often costly, time-consuming and ill-fitted.2,3 Additive manufacturing (“3D-printing) allows for the production of highly-customized and inexpensive assistive devices4, which suggests potential efficacy in the prescription of splints and casts for musculoskeletal injury.3 In the present study, a parametric, customizable splint/cast was created using a computer-aided design (CAD) package (Fusion 360, Autodesk, San Rafael, CA, USA) and produced with low-cost, desktop 3D printing (Ultimaker 2+ Extended, Ultimaker, Geldermalsen, Netherlands). Fitting of the devices was performed on five healthy ...

Patient Perspectives On Osseointegration: A National Survey Of Veterans With Upper Limb Amputation, Linda Resnik, Heather Benz, Matthew Borgia, Melissa A. Clark
Population and Quantitative Health Sciences Publications
INTRODUCTION: Osseointegrated (OI) prostheses have a unique benefit-risk profile among prosthetic alternatives and have been marketed in the United States under a Humanitarian Device Exemption since 2015. Information about upper limb prosthesis user perspectives on benefits and risks, prosthesis-user subpopulations for whom OI is most acceptable, and outcomes that matter most to patients could help inform clinical and regulatory decision-making. Recent 21st Century Cures legislation expanded the role of patient experience data in the decision-making process of the U.S. Food and Drug Administration, recognizing that patient perspectives may be informative to regulators.
OBJECTIVE: To better understand prosthesis user perspectives ...
