A prosthetic device includes a socket assembly defining a cavity and configured to receive a portion of a residual limb of a user within the cavity, a force sensing member configured to detect forces applied to the residual limb at a plurality of locations about the portion of the residual limb and generate signals based on the detected force, a vacuum system in fluid communication with the socket and configured to control an amount of vacuum applied to the cavity, and a controller coupled to the force sensing member and the vacuum system. The controller is configured to receive the signals from the force sensing member and control operation of the vacuum system during use of the prosthetic device by the user based at least in part on the signals received from the force sensing member.
