Applied kinesiology (AK) which is also known as muscle strength testing, is a method of diagnosis and treatment based on the idea that various muscles are linked to particular organs and glands, and that specific muscle weakness can signal distant internal problems such as nerve damage, reduced blood supply, chemical imbalances or other organ or gland problems. Dr Roller will find the remedy, usually herbs or nutrients, to help heal a problem in the internal organ and thus the associated muscle weakness. The combined terms “applied” and “kinesiology” describe the basis of this system, which is the use of manual muscle testing to evaluate body function through the dynamics of the musculoskeletal system.
