1. A prosthetic device control apparatus comprising:

  • at least one sensor adapted to be worn by a user, the at least one sensor detecting body movements that are indicative of a desired movement of a prosthetic device; and

    a control module in communication with the at least one sensor and receiving at least one signal based on the detected body movements therefrom, the control module having a plurality of user selectable control modes, each user selectable control mode defining a different motion for the prosthetic device, the plurality of user selectable control modes including at least a bulk control mode and a finesse control mode;

    wherein the control module simultaneously commands a first plurality of prosthetic actuators to control movement of the prosthetic device based on the detected body movements indicated by the at least one signal from the at least one sensor to achieve bulk movement of the prosthetic device when the bulk control mode has been selected, thereby moving the prosthetic device into a desired position of the prosthetic device through the desired movement of the prosthetic device; and

    wherein the control module simultaneously commands a second plurality of prosthetic actuators having actuators that are different than actuators of the first plurality of prosthetic actuators to control hand movement of a prosthetic hand of the prosthetic device based on a signal from the same at least one sensor used to control the first plurality of prosthetic actuators to achieve finesse movement of the prosthetic device when the finesse control mode has been selected, thereby manipulating the prosthetic hand through hand movement of the prosthetic device.
