http://depts.washington.edu/plpa. The project is intended to
enhance the practitioner's toolchest by providing information
about how liners interact with residual limb soft tissues and
how liners mechanically differ from one other. This information
should help practitioners select appropriate liners for their
patients. The materials testing center should also be helpful to
companies by providing detailed engineering characterizations
of their existing and emerging products.
Findings to date: Practitioner feedback from our previous reports testing elastomers, foams, and others materials [#1, #3] has been key towards the current effort. We are creating tests to characterize liner material: compressive cushioning, shear cushioning, suspension, adherence, volume accommodation, breathability, thermal conductivity, and durability. Results will be presented in an easy to understand format (see above).
