Overview
Brief Summary
The long-term goal of this research is a socket-embedded prosthesis use and socket fit monitor (E-Socket) that facilitates clinical decision-making in the diagnosis and prognosis of health issues faced by people with transtibial amputation. The overall strategy is to enhance the E-socket to include additional metrics that we identified needed from studies to date (Aim #1). Then we conduct a randomized control trial testing the diagnostic utility of the E-socket data in clinical care (Aim #2). From the data collected in that study, we develop the prognostic capability of the system (Aim #3).
Aim 3 will not involve human subject testing as it will focus on the development of the system in preparation for a future aim involving participants' own clinicians.
Note: we use the term "diagnostic" throughout our application in a general sense. The device will not be diagnosing specific diseases or medical conditions.

Outcomes
Primary Outcomes
Anterior-Distal Limb Motion
Time Frame: 12 months
Monitor anterior-distal limb motion in the prosthesis to determine if limb motions and activity changes precede changes in limb health. Interviews with the participants and questionnaires will be used to assess the outcome measure.
