Description
The lower limb prosthesis is an important assistive technology for persons with limb amputations and differences. The interface (prosthetic liner) between the rigid prosthetic socket and the residual limb is often made of silicone, urethane or thermoplastic elastomer gel. This material provides cushioning and support as well as suspension for the transtibial (below knee) prosthetic leg. Unfortunately the cost of liners range from $3-$600. This cost precludes its use in resource limited settings such as Sri Lanka. As a result patients are fit with a foam liner which has less cushioning and suspension capabilities than a gel type liner. This health care disparity may result in a lowered quality of life and mobility for these individuals. Recently a method for sustainably developing a prosthetic liner was developed by Lewis and Bateman at Brigham Young University. The liner can be created in clinic using a 3D printed mold, all of which greatly reduce the cost to an estimated $35 per liner. This research sought to provide a newly developed low cost silicone liner for a transtibial prosthesis users in Sri Lanka and evaluate patient reported outcomes.
