It tests and treats medical conditions and diseases. However, according to these "electrocardiographs" or “neurometers,”
- thermometer Another means of detecting abnormalities in the reaction point is a thermometer. This is based on the fact that the so-called “parallel hole”, which is the acupoint at the finger end of the limb, is located at the end of the meridian. Decisions are made, and the difference in the heat sensitivity is used to find a remarkably abnormal channel.
- this thermometer is good for examining changes in heat perception near the acupuncture points and for examining heat sensory nerves, but the heat used for measurement becomes a stimulus and the temperature of the entire finger rises.
