Application Of Occupation-Based Models To Edward Of Edward Scissorhands: Oa And Ehp Models, Amy Griswold, Kelsey Harris, Whitney Marwick, Whitney Wilbanks, Courtney Wild

San Marcos, Fall 2019

This presentation examines the character Edward Scissorhands, a young adult with hand deformities and poor social skills, through the lens of the Ecological Human Performance (EHP) Model. We propose occupational therapy interventions based off of the EHP model. Through the use of establishing social skills training, as well as adapting and modifying Edward’s hands with tips and attachments, Edward’s life could be immensely improved

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, …

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

Background:

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.

Objectives:

1) Review items from standardized …

Exploring Mobility Help-Seeking Behavior Among People With Physical Disabilities: A Case Study Of Jaipur Foot, Alex Podell

Independent Study Project (ISP) Collection

It is estimated that as many as 90 million people living in India experience some sort of disability (The World Bank, 2007). As India’s population keeps growing and aging, not only will the medical aspects, but also the societal impacts of disability need to be brought to the forefront of discussion, developmental strategy, and policy implementation. This study sought to analyze factors influencing the process of seeking help from formal and informal sources for people with physical disabilities. Data was collected from 10 people with physical disabilities receiving a variety of mobility aids from the NGO, Bhagwan Mahaveer Viklang Sahayata …

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. …

ASEE IL-IN Section Conference

This custom wrist orthosis project is the continuation of efforts made by students in the R.B Annis School of Engineering during the 2017-2018 academic year. Throughout this project, we have implemented the Design for Six Sigma (DFSS) methodology to guide the design process. Within the R.B. Annis School of Engineering, this methodology has been adapted into guide the DesignSpine process. We have designed a new orthosis that is custom fabricated for enhanced patient comfort. In the occupational therapy field, patients have reportedly not been wearing their prescribed orthoses/braces, which are designed to stabilize injured areas so that they heal properly. …

Developing And Testing Of An Upper Limb Exoskeleton For Stroke Patients, Drew Dudley, David Salazar

UNO Student Research and Creative Activity Fair

Objective: The main objective of this study was to determine functional and neuromuscular outcomes of stroke patients using their non-preferred hand with and without a 3D printed passive exoskeleton compared to controls using their non-preferred hand with and without the passive exoskeleton. Methods: Adults at least six months post stroke (Stroke, n = 5) and age- and sex- matched healthy controls (Control, n = 5) performed nine trials of a gross motor task while having their brain activity measured. The Fugl-Meyer and “Box and Block” test was used to measure the gross dexterity of the subjects with and without the …

Efficacy Of Assistive Devices Produced With Additive Manufacturing, James Pierce

UNO 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 …

Department of Biomechanics, University of Nebraska at Omaha

Introduction

Upper Limb Reduction Deficiency (ULD) is a congenital disability that affects the upper limb, which the Center for Disease Control and Prevention estimates that nearly 1,500 babies are born with ULD in the United States yearly ^1,2. Prior research has focused on functional treatment of the upper limbs but has lacked observance of the effects that prosthetics and limb loss incur to the trunk. Therefore, the purpose of this study is to examine the acute effects …

The Efficacy Of Custom And Prefabricated Orthotic Interventions For Common Running Related Injuries, Jake Tavernite

Writing Across the Curriculum

One of the most popular sports in the world is running. Nearly 17 million people in the United States alone crossed finish lines in road races in 2017.¹ Unfortunately, there is an extremely high rate of running related injuries (RRI) that prevent or hinder individuals from training and competing. A 2007 systematic review revealed that the incidence of lower extremity running related injuries ranges from 19.4% to 79.3%.² Orthotics are frequently prescribed as a conservative treatment option for various injuries such as plantar fasciitis (PF), patellofemoral pain syndrome (PFPS), medial tibial stress syndrome (MTSS), and stress fractures. Although …

Artful Bionics: Pushing The Limits Of Visual Expression In Prosthetic Design, Anna Kester

Honors Undergraduate Theses

Traditional prosthetic design revolves around functionality, aiming to hide and downplay an individual's limb difference as much as possible. This may not only negatively affect the user's desire to wear their prosthetic but may also negatively affect their self-confidence and sense of identity. Expression is a primary way to communicate identity, yet some traditional prosthetics may deny expression, leaving users without an immediate means to express themselves apart from the stigmatizing label of 'disability'. This study examines the ability of art when combined with bionic prosthetic technology to change the perception of disability, empower self confidence in prosthetics users, and …

A Biomimetic Approach To Controlling Restorative Robotics, Matthew T. Boots

Graduate Theses, Dissertations, and Problem Reports (ETD)

Movement is the only way a person can interact with the world around them. When trauma to the neuromuscular systems disrupts the control of movement, quality of life suffers. To restore limb functionality, active robotic interventions and/or rehabilitation are required. Unfortunately, the primary obstacle in a person’s recovery is the limited robustness of the human-machine interfaces. Current systems rely on control approaches that rely on the person to learn how the system works instead of the system being more intuitive and working with the person naturally. My research goal is to design intuitive control mechanisms based on biological processes termed …

Description Of Motor Control Using Inverse Models, Anton Sobinov

Graduate Theses, Dissertations, and Problem Reports (ETD)

Humans can perform complicated movements like writing or running without giving them much thought. The scientific understanding of principles guiding the generation of these movements is incomplete. How the nervous system ensures stability or compensates for injury and constraints – are among the unanswered questions today. Furthermore, only through movement can a human impose their will and interact with the world around them. Damage to a part of the motor control system can lower a person’s quality of life. Understanding how the central nervous system (CNS) forms control signals and executes them helps with the construction of devices and rehabilitation …
