When testing a muscle, we can use it as a generic Indicator Muscle (IM) or as a Specific Indicator Muscle. A generic Indicator Muscle (IM) is generally related to the subconscious system and gives a general response related to all the body. When using a Specific Indicator Muscle, we are testing the Muscle-Organ-Meridian Relationship and, therefore, acquiring information on how the organ and the meridian related to that specific muscle are working.
