Advancing Prosthetic Technology: 3d-Printed Robotic Arm With Micro Linear Actuators, Vu Tran, Nathan Reed, Mahdi Yazdanpour

Posters-at-the-Capitol

The increasing demand for affordable and accessible prosthetic solutions has driven innovation in the field of robotics. In this project, we present the design and development of a 3D-printed robotic prosthetic arm aimed at addressing the challenges faced by individuals with upper limb amputations. Our prosthetic arm utilizes five micro linear actuators to achieve precise and naturalistic movement. The design of the prosthetic arm prioritizes affordability and accessibility, with a focus on leveraging 3D printing technology to reduce manufacturing costs and enable customization. The use of micro linear actuators offers advantages in terms of compactness, lightweight construction, and efficient power …


Evaluation Of Concussion Assessment Tools For Collegiate Athletes, Jacqueline D. Villanueva Arevalo, Emily R. Brown Apr 2023

Evaluation Of Concussion Assessment Tools For Collegiate Athletes, Jacqueline D. Villanueva Arevalo, Emily R. Brown

Student Scholar Showcase

BACKGROUND: Due to the increase in sports-related concussions in the United States, there is a rising concern about concussion assessments in collegiate athletes with regard to long term vestibular ocular motor dysfunction and post-concussion syndrome.

PURPOSE: Due to varying practices in concussion diagnosis, this systematic review analyzed three concussion diagnostic instruments, The King Devick, Screening Concussion Assessment Tool (SCAT-5), and Vestibular Oculomotor Screening Tool (VOMS), to determine the most appropriate instrument(s) for reducing vestibular ocular-motor dysfunction and post-concussion symptoms in collegiate athletes.

METHODS: Nested Knowledge was used to identify articles from PubMed, Europe Pubmed Central, and ClinicalTrials.gov databases. Key search …


Differences In Behavioral Responses To Stress In Zebrafish: Exploring Underlying Neural Mechanisms, Jacalyn B. Russ Mar 2017

Differences In Behavioral Responses To Stress In Zebrafish: Exploring Underlying Neural Mechanisms, Jacalyn B. Russ

UNO Student Research and Creative Activity Fair

Two alternative “stress coping styles” are documented across a wide range of taxa: proactive and reactive. While behavior differences can be observed between coping styles, brain regions potentially mediating these differences have not been studied extensively. Understanding differences in how the brain processes information between the coping styles can lead to insights on how these responses might be controlled. To assess the neural mechanisms underlying alternative stress coping styles, I utilized Danio rerio (zebrafish) and the Novel Tank Diving Test (NTDT). I hypothesize (i) that proactive fish will spend less time in the lower portion of the NTDT and spend …
