Transtibial Pin Lock Suspension at Varying Distraction Values Using a Modified Air Bladder Casting System

Overview

To assess the effects various distraction values have on the 'slippage' effect of a transtibial pin-lock system

This experiment will consist of a total of four visits. The testing process will consist of a series of castings, surveys, data collection, and outcome testing that includes both endurance and aerobic exercises while wearing the check sockets of varying tension values. The outcome measures will be performed in the Nichol Hall Motion Capture Lab. * The participants will sign consent forms and three casts will be taken on the first visit. * The second visit will consist of fitting test socket A, which includes socket adjustments and the dynamic alignment. Once the socket is properly fit on the subject, we will begin their three trials (with two to three minute breaks in between trials) of the Time Up and Go assessment (TUG) followed by the Prosthesis Evaluation Questionnaire (PEQ) survey. * Visit three will be comprised of socket B fitting, alignment, and testing. The subjects will proceed with the same procedure as stated in visit two. Following the outcome measures, participants will take the PEQ survey for socket B. * Visit four is the final visit of testing and data collection. Socket C will be presented to the subject and they will go through the same dynamic alignment process and outcome testing as the previous visits. Once finished, the subjects will take the final PEQ survey on socket C and receive their compensation.
