"Triangle of health", or the basis of applied kinesiology
In 1964, George Joseph Goodhart, Jr., Ph.D., founder of Applied Kinesiology, first demonstrated the effectiveness of using manual muscle testing to assess body function.
The basis of the new direction was the principle of "Goodhart's triangle", the essence of which is the balance of the three "sides" of health - structural (as the basis of the triangle), chemical and mental factors. The points of intersection of the sides reflect the state of the canal-meridional system.
The Health Triad describes the three main causes of health problems - that is, all diseases are associated with one, two or three sides of the triangle.

STRUCTURE - structural factors
CHEMICAL - chemical factors
MENTAL - mental factors
N - nerve,
NL - neurolymphatic reflexes (F. Chapman),
NV - neurovascular reflexes (Beneta),
CSF - cerebro-spinal fluid primary craniosacral mechanism,
AMC - acupuncture-meridional system
Thus, if all sides of this triangle are equal, then the person is healthy. Obviously, a violation of one side (primary violation) will lead to a violation of the other (secondary violation), and then, possibly, the entire triangle.
Applied kinesiology is a system that evaluates the structural, chemical and mental aspects of health using manual muscle testing in combination with other standard diagnostic methods.
Diagnostic methods of applied kinesiology will help to determine in a timely manner which of the parties began to be distorted first - since the elimination of the primary violation will allow the secondary to return to normal.
Applied kinesiology allows the doctor to assess the functional balance in the "health triad" and prescribe effective treatment for exactly the side (s) where there are disorders.
If a doctor evaluates each patient on all three "sides", then this greatly increases the chance of finding the root cause of health problems.
Consider the following example: A patient who has been suffering from bowel irritation for a long time experiences pain in the lower back. The nutritional balance in the body in such a patient is seriously disturbed due to malabsorption (impaired absorption of substances) and, possibly, a long course of antibiotics. The appearance of pain in the lower back is associated with a dual innervation of the lower back and intestines, and the presence of stress in the patient can further complicate the situation. In the course of treatment, it is extremely important to analyze all three factors and restore the balance in the "triangle of health" for the patient's full recovery.
Thus, the goal of applied kinesiology is to restore the balance of structural, chemical and mental factors.
