Walking With Poles Improves Step Length Of Simulated Prosthetic Gait, Marissa Elquist, Daniel Perez, Jonathan Garcia, Brady Owens

UNLV Theses, Dissertations, Professional Papers, and Capstones

Individuals with lower limb loss often demonstrate gait deviations which cause instability and asymmetry. Walking with poles has been shown to improve stride length and stability in older adult and other patient populations. The enhanced arm involvement in bipedal walking with poles has the potential to facilitate interlimb coordination among arms and legs, and therefore is likely to improve prosthetic gait. The purpose of this study was to examine the effect of walking poles on temporal gait parameters and the center of mass (COM) displacement during prosthetic and simulated prosthetic gait. It was hypothesized that walking with poles would improve …

Direction Of Attentional Focus In Prosthetic Training: Current Practice And Potential For Improving Motor Learning In Individuals With Lower Limb Loss, Alexander Bonczyk, Maria Katrina Tillada Dimapilis, Sarah Partridge, Samantha Ruiz

UNLV Theses, Dissertations, Professional Papers, and Capstones

Objective: Adopting an external focus of attention has been shown to benefit motor performance and learning. However, the potential of optimizing attentional focus for improving prosthetic motor skills in lower limb prosthesis (LLP) users has not been examined. In this study, we investigated the frequency and direction of attentional focus embedded in the verbal instructions in a clinical prosthetic training setting.

Methods: Twenty-one adult LLP users (8 female, 13 male; 85% at K3 level; mean age=50.5) were recruited from prosthetic clinics in the Southern Nevada region. Verbal interactions between LLP users and their prosthetists (mean experience=10 years, range=4-21 years) during …

Patient Engagement In Cosmetic Designing Of Prostheses: Current Practice And Potential Outcome Benefits, Kenneth Repayo, Cailin Mitchell, Matthew Tillitt, Collin Weber

UNLV Theses, Dissertations, Professional Papers, and Capstones

Purpose: Making a prosthesis for an individual with limb loss is a highly personalized process. A currently unexplored area is whether there are tangible benefits in greater patient engagement during the making of their prostheses. We examined the current practice of engaging patients in prosthetic cosmetic designing and identified factors associated with patient outcomes. Methods: This cross-sectional study surveyed 104 prosthetists and 25 prostheses users. The questionnaires covered aspects of prosthetic prescription, users’ perceived level of engagement, and self-reported outcomes. Regression analyses were used to examine the associations between perceived level of engagement, satisfaction, and other outcomes. Results: Among prosthesis …

Biomechanical Analysis Of Gait Kinetics Resulting From Use Of A Vacuum Socket On A Transtibial Prosthesis, Maria De Lourdes Ramos Gonzalez

Honors College Theses

The technology and design of lower limb prosthetics have evolved greatly since their introduction. The current study proposed to compare the effects of a conventional pin socket attachment and a vacuum socket attachment for a transtibial amputee. Whereas traditional measurements of gait utilize force plates and camera systems, this study made use of a small tri-axial load cell located at the base of the socket to measure the forces and moments exerted during a regular gait cycle. The hypothesis tested stated that a vacuum pump socket attachment, when compared to a non-vacuum (pin) socket, will have a significant effect on …
