Biomechanical Analysis Of Gait Kinetics Resulting From Use Of A Vacuum Socket On A Transtibial Prosthesis, Maria De Lourdes Ramos Gonzalez
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 …
Design And Development Of A Stair Ascension Assistive Device For Transfemoral Amputees, Casey Michael Barbarino
Design And Development Of A Stair Ascension Assistive Device For Transfemoral Amputees, Casey Michael Barbarino
Master's Theses
Transfemoral amputees around the world experience increased difficulty in climbing stairs due to lack of muscle, balance, and other factors. The loss of a lower limb greatly diminishes the amount of natural force generation provided that is necessary to propel oneself up stairs. This study investigated possible solutions to the problem of stair ascension for transfemoral amputees by the means of designing and developing an externally attachable device to a prosthesis. The number of amputations from military service has greatly increased since 2008, which shows there is a clear need for assistive devices (Wenke, Krueger, & Ficke, 2012). With the …
