A method of hysteretic palpatory training includes providing a wire or a
computer controlled actuator having a plunger that hysteretically resists
the application of a palpatory force. An increasing palpatory force is
applied in a first direction to the wire or the plunger, whereupon the
wire or plunger hysteretically resist displacement from a first position
to a second position. The palpatory force is then withdrawn whereupon the
elasticity of wire or the elasticity emulated by the plunger causes it to
return to a position intermediate the first and second positions. The
applied palpatory force versus displacement in response to applying and
withdrawing the palpatory force to the wire or the plunger is then
detected.
