A.K. does not substitute clinical exams; it complements them. For example, muscle testing is particularly useful for detecting problems before they arrive at full-blown pathology. Many suffer from chronic headache or back pain, then go from doctor to doctor, performing test after test only to be told they have nothing wrong with them. A doctor using Applied Kinesiology on the other hand is often able to pull up an old physical trauma that may be at the roots of the patient's symptoms. The accuracy of this form of diagnosis is astonishing and is not possible with traditional clinical exams.
