Developing Aligned Nerve Scaffolds In A 3d Type-I Collagen Gel, Gabriel David
Developing Aligned Nerve Scaffolds In A 3d Type-I Collagen Gel, Gabriel David
Biomedical Engineering Undergraduate Honors Theses
Despite significant progress in the field of peripheral nerve repair, clinical success is still limited, leaving millions to suffer from peripheral neuropathy with billions spent every year for treatment. Nerve repair methods that are capable of maximizing the regenerative properties of peripheral nerves are greatly desired in the field of medical science. This research aims to fill the gap between modern methods and the future of nerve repair by creating type-I collagen scaffolds with aligned degradation pores that will assist and nurture nerves growing through them. This is achieved by incorporating adipose stem cells into type-I collagen hydrogels and aligning …

Current face shields used in home and institutional healthcare settings create hardships for their wearers, which makes normal work routines more difficult. Recent mandates require healthcare workers to wear both surgical masks as well as plastic face shields when tending to patients. Unfortunately, the majority of face shields have been designed for hospital settings, which does not address the specific requirements for in-home therapist use. Some of the issues include their restrictive size, tendency to fog, susceptibility to glare, and sterilization and re-use issues. Our team proposes to design a face shield for homecare occupational therapists that addresses their unique …

Cumulative Shear In Vitro Model, Jared Olson, Alex Deppe, Braden Andrews
Biomedical Engineering
The purpose of our project is to find a reliable method of Subclinical Atherosclerosis detection by measuring the pressure drop across an artery. This model is intended to display how a pressure change correlates with arterial shear rate, and how a decrease in shear rate is ultimately related to atherosclerosis wherein early detection could prove life saving for millions of patients worldwide.

We are working with a non-profit organization in Ukraine that provides wheelchairs/strollers to families of disables children who cannot afford them. Their current preferred solution is a baby stroller. The organization asked us to create a wheelchair that is cost efficient, light and collapsible to be used for children ages up to thirteen years old. We will be creating an alpha prototype wheelchair by modifying a basic wheelchair that we purchased. This modifications include adding a headrest that is adjustable and provides a sufficient support for children within the age group given to us and diverse levels of disabilities. We …
Thenar Muscle And Transverse Carpal Ligament Relationship, Jeremy Granieri Loss
Thenar Muscle And Transverse Carpal Ligament Relationship, Jeremy Granieri Loss
ETD Archive
The transverse carpal ligament (TCL) acts as a partial origin for the thenar muscles (abductor pollicis brevis (APB), flexor pollicis brevis (FPB), opponens pollicis (OPP)). The attachment between the thenar muscles and TCL implies a relationship between the tissues. The thenar muscles rely on their origins for thumb motion and force production. However, individual thenar origin information is lacking. Further information regarding the anatomical relationship between the individual thenar muscles and TCL may provide insight into thenar muscle function. In addition, the TCL responds to thenar muscle contraction as shown by volar migration of the TCL during various thumb movements. …
Characterizing The Effects Of High-Intensity Exercise On Balance And Gait Under Dual-Task Conditions In Parkinson’S Disease, El Iva Baron
Characterizing The Effects Of High-Intensity Exercise On Balance And Gait Under Dual-Task Conditions In Parkinson’S Disease, El Iva Baron
ETD Archive
Parkinson’s disease (PD) is a neurodegenerative disorder, characterized by four cardinal motor symptoms including bradykinesia, tremor, rigidity, and postural instability, and non-motor symptoms including cognitive impairment. Daily activities, such as walking and maintaining balance, are impacted due to impairments in motor function, and are further exacerbated with the addition of cognitive loading, or dual-tasking (DT). High-intensity exercise has demonstrated centrally-mediated improvements of PD symptoms, with additional positive effects on overall health. The goal of this project was to identify changes in dynamic balance recovery and gait function under conditions with and without increased cognitive load after a high-intensity exercise intervention …
Feasibility Of Using An Equilibrium Point Strategy To Control Reaching Movements Of Paralyzed Arms With Functional Electrical Stimulation, Matthew Huffman
Feasibility Of Using An Equilibrium Point Strategy To Control Reaching Movements Of Paralyzed Arms With Functional Electrical Stimulation, Matthew Huffman
ETD Archive
Functional electrical stimulation (FES) is a technology capable of improving the quality of life for those with the loss of limb movement related to spinal cord injuries. Individuals with high-level tetraplegia, in particular, have lost all movement capabilities below the neck. FES has shown promise in bypassing spinal cord damage by sending electrical impulses directly to a nerve or muscle to trigger a desired function. Despite advancements in FES, full-arm reaching motions have not been achieved, leaving patients unable to perform fundamental tasks such as eating and grooming. To overcome the inability in current FES models to achieve multi-joint coordination, …
Design Of Exercise Equipment For Wheelchair Users: A Case Study In Accessibility Standards, Kate Craddock Rescsanszky
Design Of Exercise Equipment For Wheelchair Users: A Case Study In Accessibility Standards, Kate Craddock Rescsanszky
Honors Scholar Theses
Engineers must consider a number of aspects of every project they work on. Accessibility is one aspect that presents a unique challenge. Rather than being based on absolute material parameters, accessibility is based on how people interact with technology and their built environment. Since 1990, the Americans with Disabilities Act has been the predominant standard in accessibility because of its wide reach and legal mandate. In addition to the ADA, the ASTM and the Institute for Universal Design offer helpful guidelines for designing for accessibility. However, in addition to standards, guidelines, and recommendations, it is important to consult the intended …
