Apply the sudomotor (sweat) function test

An image showing the ideal position for pad placement, plus two alternative possible locations
  • Choose a position on the sole of your foot to apply the pad, ideally on the ball of the foot as shown (far left picture).
  • If the ball of the foot has a lot of callus, apply the pad to one of the two alternative positions.
  • Place the pad in the same spot each time to help track progress more accurately.
  • During the 10-minute testing, ensure that you keep your foot raised and that the part of the foot where the pad is attached is off the floor.
