An augmented reality method of visualising transtibial socket pressures and limb orientation

The measurement of in-socket pressure distribution has been a research concern for decades. Inappropriate application of pressure to the residuum has been implicated in discomfort, pressure injury, development of skin conditions and subsequent reduction in function [1]. Despite this interest, measurement systems have not moved from research tools into routine practice. One reason suggested for this is difficulty in interpretation: they lack the context of position relative to the measured socket and in associating the results with the orientation of the socket during movement [2]. These aspects may be improved by using an augmented reality system to visualise results by providing a scaled model, displaying measured pressure values and oriented to provide positional context.
