The following invention is a device for measuring the force applied by the residual limb of an amputee to the distal region of a socket. The device has an upper surface with a “force sensor measuring region” that maintains a central location on the upper surface of the DFMD. The DFMD is affixed to the inside surface of the distal most area of the socket and maintains a permanent location of the “force sensor measuring region” of the device. Regardless of physical characteristics or changes to the socket, liner, socks, proper or improper placement of the limb into the socket, the consistent location of the “force sensor measuring region” on the DFMD provides congruent force data as it relates to the force applied by the socket to the distal area of the residual limb. The data collected by the DFMD is processed and modified by a software algorithm into meaningful data for the user and/or medical professional. Applicable uses for the data relate to the fit of the socket, limb volume management strategy, and vacuum suspension efficacy.
