Symposium; Assessment of stump-socket interaction load: Critical appraisal of state-of-the-art measurement techniques to quantify in-socket tissue stress and strain.

Abstract
Prosthetic socket fit related discomfort and pain are among the most prevalent complaints of prosthetic users. Despite exciting developments in socket design and manufacturing, the problems expressed by prosthetic users remains a considerable challenge for the prosthetist. This is partly due to the fact that tissue load occurring inside the socket during use is complicated to quantify.

Over the years, measurement techniques have been developed to quantify tissue load within the socket, some with clinical application potential. These techniques include, amongst others, measurement of stump-socket interface pressure, ultrasound and oximetry.

These techniques all assess different aspects of tissue load. Pressure sensors capture stresses at the stump-socket interface in either perpendicular or shear components or both. Ultrasound has been used to quantify tissue deformation (strain) and especially residual bone movement within the socket. Oximetry can be used to assess the oxygenation of the stump tissue, which is affected by load as it can influence blood saturation (oxygen) and perfusion ( Flow) impede blood supply.

In this symposium, we’ll critically discuss the state-of-the-art in the application of such technology to assess and improve socket fit. Questions that are dealt with are: 1) what is the current technical state of this technique, 2) what is the validity of these assessments, 3) what is the current clinical applicability, 4) what future development are required. Three experts in the field will deal with these questions based on their recent research results.
