1. An apparatus for detecting myoelectric signals from a muscle which is to be coupled to a myoelectric prosthetic device, said device having a device electrode pair which is coupled to the muscle, the apparatus comprising:

  • a plurality of electrode pairs arranged in an array, wherein the distance between the electrodes in each electrode pair is the same as the distance between the electrodes in the device electrode pair, wherein the electrode pairs are sufficient in number and are sufficiently spaced apart to cover a wide area of the muscle so that the muscle can be tested without it being necessary to reposition the electrode pairs;

    circuitry coupled to the electrode pairs for sampling signals from a plurality of the electrode pairs during a muscle contraction and for providing output signals for each electrode pair during the contraction; and

    a display for displaying the output signals for a plurality of the electrode pairs at the same time.
