Lower Body Gait Variability As A Distinguishing Feature In Humans, Tyler M. Wiles, Seung Kyeom Kim, Nick Stergiou, Aaron D. Likens

UNO Student Research and Creative Activity Fair

Most humans have a fingerprint that is unique and persists throughout life. The same may be true for gait. Each person is unique physiologically and biomechanically, and has experienced a unique progression of life including injuries, habits, hobbies, or lifestyles that all contribute to navigating the world. Those individualized experiences, whether intended or not, are potentially on display in gait. We hypothesized that there are gait characteristics intrinsic and unique to everyone, so that everyone has a unique “gaitprint”, similar to humans possessing unique fingerprints. To test our hypothesis, we recruited thirty healthy young adults between the ages 19-35 as …

Functional Outcomes Of Noninvasive Sensory Feedback In Upper Limb Prostheses: A Meta-Analysis, Libby Caldwell

UNO Student Research and Creative Activity Fair

Noninvasive sensory feedback applies vibration or pressure to the residual limb and is thought to improve the functionality of upper limb prostheses. However, the efficacy of this approach has not been sufficiently investigated, particularly regarding actual amputee efficacy. The purpose of this study was to evaluate the functional benefits of noninvasive sensory feedback in upper limb prostheses through a meta-analysis. Electronic databases (MEDLINE, Web of Science, and PubMed) were searched up to October 2022 using the following search terms: (prosthesis OR prosthetic) AND (hand OR arm OR forearm OR transradial OR “upper limb” OR “upper extremity) AND (tactile OR haptic …

Walking with a Load on Wheels: Potential Effects of Bidirectional Springs on Walking Economy

Have you ever noticed how your arms alternatively flex and extend when pushing a heavy shopping cart? Accelerating and decelerating heavy masses, such as a shopping cart, can require much effort. During walking, we alternatively accelerate and decelerate our Center of Mass (COM) in every gait cycle, which can require even more effort if we accelerate and decelerate a load while walking. Theoretically, this effort can be reduced by timing the acceleration and deceleration of the load's mass opposite to the individual's COM. Previous studies have …

Humans routinely perform a variety of activities such as walking, running, driving, and typing, all of which require coordination among different body joints. For instance, walking and running involve rhythmic movements of the arms and legs. The involvement of the upper …

Traditional gait metrics, like speed, cadence, coordination, as well as non-linear measures, appear related to Timed Up and Go (TUG). Timed Up and Go is a clinical measurement related to physical, socioeconomic, and psychological parameters, as well as overall health. TUG can be used as a health …
