Prospective Intervention Study Using Immediate-Fit, Adjustable Prostheses for Persons With Lower Limb Loss in...

The aim of the study is to test the feasibility of an immediate-fit, adjustable prosthesis (iFIT Prosthesis) for persons with limb loss in Botswana.

As part of the University of Pennsylvania and University of Botswana's long-term partnership, 18 persons with limb loss were fit at four different locations in Botswana. Patients were followed for 4-9 mos after fitting with an interview and Prosthetic Comfort and Utility questionnaire.

Out of 18 participants, 13 were located and provided follow-up feedback. Seven of the original 13 were still wearing the adjustable socket, while three reverted to their old socket and three did not use any socket. The highest positive rated question was the ability of the socket to accommodate changes in volume. Twelve (92%) of the participants said that they would recommend the system, yet cited that bulk and lack of cosmetic cover as major issues. For participants who had a conventional prosthesis, it took over a year to get their device through prosthetists using conventional fabrication techniques.

This socket system seems to be a feasible option for persons with lower limb loss in Botswana. To address the issues raised by participants and enhance user acceptance, the immediate-fit, adjustable system should become less bulky and include a cosmetic cover.
