An apparatus for measuring muscle condition comprising an upper housing having a top; a lower housing having a base at one end and a top member at another end and a guide member adjacent to the top member; a probe member connected to the upper housing and having an end cap which, when the apparatus is at rest, is adjacent to the base to thereby define a plane, and a bias member attached to the end cap at one end and attached to the top member of the lower housing at another end, the probe member being slidably attached to the lower housing; a force measuring sensor for measuring the amount of force being exerted when the top of the apparatus is pressed; a shift measuring sensor for measuring the distance the probe member moves beyond the base; and a controller to direct the number of single measurements of force and of shift to be taken during a single measurement cycle, to control the amount of force to be exerted at each single measurement, to record measurement data collected, to derive a measurement average for a session constituting more than one measurement cycle, and to display and compare measurement averages between sessions.
