To eliminate variables while casting the student investigators will be using a system very similar to that of Ossur's ICEX, developed in Reykjavik, Iceland. The ICEX system uses an air bladder system that allows a socket to be constructed directly onto the residuum; resulting in even pressure distribution during the time of casting. The ICEX system will ensure that the student investigators are obtaining consistent socket pressures and that the team will be precisely testing the distraction values on the multiple sockets obtained in this experiment. During this experiment, the researchers will be using a modified air bladder system.

A digital fish scale will be attached to the distal strap of a gel liner to measure the distraction values while casting. A digital fish scale can measure in pounds or kilograms depending on how you set it. The digital fish scale will be held in place while casting to maintain a consistent tension between the scale and the residual limb.

This assessment requires a standard armchair, a stopwatch, and a walkway clearly marked at 10 feet. The participant will be instructed to begin to walk on the word "Go". Promptly, the participant will stand up from the armchair, walk to the line on the floor at a normal pace, turn, then walk back to chair at their selected pace, and sit down again. Due to the fact that the participant will have to do this task three time they will be given a two to three minute resting period in between trials.
