My chiropractor sister is probably more familiar with this concept than I am.
According to my DailyOM: Kinesiology taps into body wisdom to find imbalances and blockages of qi flow, even detecting disruptions in the chakras and aura.
OK, but also according to my DailyOM: A simple "self" kinesiology method involves asking your body questions by testing the muscle response in your fingers. For instance, you may want to know if you are suffering from allergies. Make a circle with two fingers. With your other hand, place one finger into the circle. Ask your body whether you are allergic to wheat, for instance, and then push your finger against the place where the circled fingers touch. If the answer is yes, it will be difficult for your finger to break through the circle. If the answer is no, then the circle will be easily broken.
Is this true? If I'm doing the test right, I should be allergic to wheat, but I've never avoided it, and I haven't blown up yet.
