JET Kinesiology teaches people how to do muscle testing. The company was started by CEO James B. Stevens, and it claims you can learn to do muscle testing for a variety of conditions within weeks. Muscle testing, also known as applied kinesiology, is a controversial method of diagnosing and treating physical and mental conditions. It is not to be confused with the science of kinesiology, the study of human movement known as biomechanics.
Theory
According to goodHealthinfo.net, muscle testing originally came from traditional Chinese medicine. It is a noninvasive way to evaluate the body's imbalances. The testing is performed by evaluating your response when slight pressure is applied to a large muscle. In theory, muscle testing can provide information about the function of your organs, nutritional deficiencies or food allergies that might afflict you and whether herbs or other remedies might help you.
JET
You can learn how to muscle test accurately in a matter of weeks, according to JET promotional materials. JET offers classes in subjects that include muscle testing basics, food supplement testing, testing for negative emotions, psychological testing, food allergy testing and testing for making important decisions. JET has patented a SmartStikTester that is said to aid in accurate muscle testing.
Critics
The Quackwatch website, run by medical doctor Stephen Barrett, writes that applied kinesiology was invented in 1964 by chiropractor George Goodheart. Many chiropractors, as well as other alternative medicine providers, use AK in their practices. Barrett terms the practice of muscle testing by JET and other practitioners as "pseudo scientific." Clinical studies have not backed up the effectiveness of muscle testing, and one study found that "muscle response appeared to be a random phenomenon."
Considerations
JET offers to return your tuition money if you complete the course and are unsatisfied for any reason. That appears to be a solid, money-back guarantee. Nevertheless, you might want to think long and hard before spending a substantial amount of money --- the cost of a single JET class is advertised at up to $199 as of March 2011, although discounts appear to be available --- on muscle testing classes that lack scientific backing. As Quackwatch concludes, "The concepts of applied kinesiology do not conform to scientific facts about the causes or treatment of disease. Controlled studies have found no difference between the results with test substances and with placebos. ... If you encounter a practitioner who relies on AK muscle-testing for diagnosis, head for the nearest exit."
