Applied kinesiology, also known as muscle testing, is a method of diagnosis and treatment based on the belief that various muscles are linked to particular organs and glands. Specific muscle weakness can signal internal problems such as nerve damage, reduced blood supply, imbalances, organ or gland problems. By correcting this muscle weakness, you can help heal a problem in the associated internal structures. Use to treat abdominal pain, diabetes, headache, learning disabilities, osteoporosis, Parkinson’s disease, vertigo and even cancer.
