Impedance readings at ST-36, ST-37, ST-39, and GB-34

Readings of impedance taken from four acupoints on the same subject, over a 14 hour period on the same day. Kovich's hypothesis is that information about the states in each organ are communicated to the organ's related acupoints in realtime via an electrical wave, and that these states are reflected in various states at the acupoint, including the skin impedance and temperature. When an organ has been stressed for some time, other states may also appear at its related acupoints, such as tenderness, shooting pains, redness, rough skin, boils, and pain in the nearby joints. The experiment shows that the impedance changes greatly throughout the day, and the peaks appear to correspond with periods of increased stomach activity, such as when digesting food.
