Brief Summary:
The goal of iFIT Prosthetics, LLC® was to create and commercialize a modular, immediate fit, fully adjustable, transtibial prosthesis system suitable for mass production using high strength injection molded polymer materials. This goal was achieved and the aim of this project is now to conduct a feasibility and effectiveness study and to assess the design of the device. The investigators will be fitting transtibial amputees that are current prosthesis users with the iFIT device. Patients will wear the device for 2 weeks in order to compare the device to their own. They will report any device breakages or adverse events. They will also fill out a questionnaire to determine if the iFIT prosthetic is a feasible option for treating patients with limb loss.

Arm Intervention/treatment
Experimental: iFIT Group
This is a feasibility and effectiveness study to assess the iFIT transtibial prosthesis as a viable alternative to a traditional prosthesis. We also hope to gain information that will influence future design iterations.
Device: iFIT Transtibial Prosthesis
Transtibial amputee volunteers will be fit with the iFIT device and instructed on its use. Patient will wear the iFIT device for a two week time period according to a provided wear schedule. At the end of this time patient will rate it for comfort, stability and ease of use.

Primary Outcome Measures :
  1. Questionnaire [ Time Frame: 2 weeks ]
    Participants will fill out an evaluation on their current prosthesis, and the iFIT prosthesis after a two week time interval. The questionnaire intends to compare the immediate fit prosthesis to the conventional prosthetic to determine if it is a feasible alternative for persons with limb loss.

Secondary Outcome Measures :
  1. Number of participants with device related adverse events [ Time Frame: 2 weeks ]
    We will record any unfavorable events such that occur including: skin irritation, skin breakdown, falls, or mechanical failures.
