During a visual diagnosis, you inspect the appearance of a patient's ears to spot any abnormality that would signal a pathology associated with an auricular point:
Palpation diagnosis mainly involves feeling the ear with a finger or probe to detect any indications of pathology in the corresponding body part/organ. Such indications include:
For electrical resistance diagnosis, Dr. Li-Chun Huang uses a probe from her electrical detection device to inspect a patient's ears for variations in electrical resistance. She would hold an ear for inspection with her non-dominant hand and use her dominant hand to control and direct the probe. When the probe detects a lower resistance at a particular point, the machine makes a sound to signal this electrical variation - this reaction is referred to as a "positive response."
Typically, the intensity of a positive response reveals the severity of the associated conditions. When a positive response is stronger, the signal sound made by the device becomes louder and higher in pitch, which, in turn, indicates that the pathology associated with the auricular point is more severe.
For the points listed above, detecting a positive response alone may not necessarily indicate an associated pathology. Under normal circumstances, the electrical resistance at these points is already lower. Therefore, additional evaluation is required for these points to determine if any problems exist.
To systematically examine over 160 points on an ear during an electrical resistance diagnosis, Dr. Huang developed a routine that includes 14 pathways for the probe to follow. As listed below, most routes focus on examining either a system or a portion of the body.
