Researchers now say that practitioners don't have to use a lot of force or pressure to elicit the body's own healing response as the body has its own energy or "biomagnetic field" produced by the heart and circulatory system. That field can be altered by acupuncture needles, light and touch therapies, homeopathy, massage, and even by the therapists' own positive thoughts.
Studies in the past have shown scientific evidence that this type of energy medicine works. Orthopedic surgeons use small amounts of electrical current to stimulate the healing of bone fractures and doctors use electrical nerve stimulation to help ease pain. Thus researchers say, alternative therapy practitioners who are sensitive to their patients can use their own energy field to help stimulate the healing response.
Tiny fields [of energy] have big effects on cells hence, therapy can be done with less energy and more effectiveness . Treating a shoulder injury could be a matter of getting the right amount of energy in the right place. In conclusion researchers say practitioners should use their intuition to help them figure out how much is the right amount of energy for each patient.
