Claim:
1. A device for foot zone therapy, said device comprising: a frame; a rotatable roll rotatable about an axis; an interchangeable contiguous sheet wrapped around and attached to said rotatable roll to rotate with the rotatable roll about the axis and provided with a plurality of knobs configured to press against a foot sole, and positioned in locations having a collective outer periphery defining a shape generally consistent with a size and a shape of the foot sole; whereby rotating the rotatable roll is configured to bring a sub-set of the knobs into contact with a sub-portion of the foot sole, while separating remaining knobs from other portions of the foot sole; wherein the rotatable roll is configured to rotate on the frame intermittently in a predetermined timing pattern and in just one direction, the direction of rotation being such that, as the device is operated, the effect of the knob proceeds from heel towards toes, but not in the reverse direction; and a brace attached to the frame with tightening bands, configured to engage over a knee and to drive the foot sole toward the rotatable roll; wherein the rotatable roll is configured to move the foot sole from heel to toe during rotation; wherein the device is provided with a motor which rotates the rotatable roll in the just one direction of rotation; wherein the motor has a stoppage time between rotation cycles adjusted by a time delay circuit to establish the intermittent rotation on the rotatable roll on the predetermined timing pattern; wherein the rotatable roll cannot rotate in a direction opposite the just one direction.
