In this paper, we describe the development of a pistoning evaluation procedure that relies on two motion capture systems: a magnetic motion capture system used to measure the motion of the residual limb and an optical motion capture system used to measure the motion of the socket.  Through synchronization of the two motion capture systems, the motion of the residual limb relative to the socket can be determined to derive the amplitude of pistoning.
