This book fills a gap in the complementary medicine literature: step by step, Dr. Lechner introduces systemic kinesiology. The focus is on uncovering deep-seated stress phenomena. The arm length reflex test is the tool that allows the therapist to ask questions of the patient's organism and diagnose the energetic conditions of the disturbances. The author clearly presents the execution of the test and the assessment of the responses that the body provides in the form of reflex reactions, as well as the conceptual models underlying systemic kinesiology.
