I originally found the following information elsewhere in the internt, and modified for inclusion here.
The working theory behind this technique is that the body has the ability to heal itself and will do so when the energy needed to make repairs is made available through balancing and syncronization of the body's total energy. Bio Energetic Syncronization Technique (B.E.S.T.) maintains that when a correct spinal adjustment is given, not only is nerve interference lessened, but more significantly, a change has been made in the body's energy fields. This concept of energy fields is new to most patients and to most doctors. However, the existence of these fields has been proven definitively through years of Medical research. B.E.S.T. has found a way to use and balance these energy fields. B.E.S.T. technicians believe that the total energy each living organism has is divided between a physical field and a mental field. The distribution of these energy fields is automatically regulated according to the kind of activity in which the individual is engaged. B.E.S.T. researchers have found that most sick people have a certain amount of their body's vital energy diverted into an emotional field. Doctors of this technique maintain that no energy can be in the emotional field unless it has been borrowed from either the physical, the mental, or both. When energy is borrowed from one field, it no longer exists in another and thereby an imbalance occurs causing deficiency in a particular field. Probably the most significant aspect of B.E.S.T. is that it provides the doctor with an effective and reliable means of balancing and syncronizing the body's mental and emotional fields with that of the physical field. As energy accumulates in the emotional field, the physical field simply doesn't have enough. This results in the back muscles receiving less than their normal energy supply. Often this deficiency is greater on one side of the body. When this happens, the muscles on one side of the spine have more strength, relatively, than those on the other, and one or more vertebrae is 'pulled' out of place allowing the disc to swell or bulge on the deficient side. Rather than force the misplaced vertebra back into position, B.E.S.T. re-distributes the energy supply so that the spinal muscles receive an equal amount and as a result, the muscles themselves pull the misplaced vertebra back into it's normal position. B.E.S.T. is performed entirely by hand. Leg lengths are checked and various muscle strengths compared. Contact areas of the body called 'switches' are also checked. The activation of these points allows the body to normalize the flow and distribution of energy.
Milton Ted Morter, Jr. (of Rogers Arkansas) developed Bio Energetic Synchronization Technique (B.E.S.T.) in the mid-1970's. It is "a holistic program that coordinates and balances the workings of all the systems of the body."[1] Dr. Morter defines B.E.S.T. as "a nonforceful chiropractic technique for the 21st century that removes interference from the nervous system by the use of the hands." [2] According to Dr. Morter, nervous system interferences occur when "subtle pulses" in different parts of the body are not "synchronized." [3]
B.E.S.T is a component of the Morter HealthSystem, which is promoted as "an advanced, alternative health care system based on B.E.S.T. that corrected the CAUSE of disease, not just symptoms." [4] A 1993 brochure describes Morter as "one of the world's leading pioneers in MindBody Healing for more than 25 years" and a former president of Logan Chiropractic College (1979-1980) and Parker Chiropractic College (1982-1984). [5]
Morter claims that his treatment will correct physical (biomagnetic), nutritional, and emotional stresses. His system is taught at seminars, many of which are sponsored by the Parker School for Professional Success, a prominent practice-building organization. The system is also taught at Life College West.
Chiropractor doctors use the Morter HealthSystem B.E.S.T. technique to renormalize the body's energy field so that it can become revitalized... In a healthy body there is no polarization of north or south energy...
Health can be restored through (1) correct interpretation of body language, (2) complete switching during each treatment session, (3) the correct transfer of energy, (4) the exact synchronization of body pulsation, (5) the correct nutritional program, and (6) sufficient time [2].
Development and repair of the body is controlled by its electromagnetic field. Imbalance in the patient's electromagnetic field causes unequal leg length, according to B.E.S.T. proponents. Chiropractors can instantly correct this condition by applying his/her own electromagnetic energy to proper points on the body. The Chiropractor detects imbalances using their fingers and thumbs. Two fingers on each of the chiropractor's hands are North poles, two are South poles, and the thumbs are electromagnetically neutral. When the chiropractor detects imbalance, he/she holds their hands for a few seconds at "contact points" on the patient's body until "pulsation" is felt and the patient's legs test equally long. B.E.S.T. practitioners recommend that such testing be started early in infancy and continued at least monthly throughout life.
According to literature about Dr. Morter's HealthSytem B.E.S.T.: The two principal sources of physiological toxins affecting patients are: (1) over-consumption of protein and (2) imbalance of the body's timing system, caused by stresses such as trauma, toxicity and [negative] thoughts.
