The test can be used to self-test for phytoneurological disorders. Irregular lifestyle, emotional stress, and excessive fatigue are important triggers for phytoneurological disorders. If you have the above conditions, and you have mood swings, or are irritable for no apparent reason, the prone test may be positive. The method of lying test is to count the pulse rate for 1 minute in lying position, then count the pulse rate for 1 minute after getting up. An increase of 10-20 times from lying to standing position is considered as increased sympathetic excitability, while a decrease of 10-20 times from lying to standing position is considered as increased parasympathetic excitability; increased sympathetic or parasympathetic excitability is considered as phytoneurological dysfunction. It should be noted that the diagnosis of phytoneurological dysfunction can not rely on self-testing methods of diagnosis, suspected phytoneurological dysfunction need to go to a professional hospital in time for a clear diagnosis, the cause of the treatment, so as not to delay the condition.
