Clinical Kinesiology was developed by Dr. Alan Beardall DC from the work of Dr. George Goodheart DC who in the early 1960’s, developed and expanded the use of traditional muscle testing into what became known as Applied Kinesiology. Historically, muscle testing was used to evaluate the function, range of motion, neurological competence and strength of muscles in an attempt to diagnose and treat a range of structural and physical problems. Having made the diagnosis, a hands-on therapy [osteopathy or chiropractic] was the usual treatment.
Dr Goodheart found and then researched the links between specific muscles and their associated organs, meridians and acupuncture points, which then led him to examine the role of nutrition in relation to the meridians. After considerable research with chiropractic colleagues, he proposed that the causes of weakness in muscle testing could be attributed to 3 main categories:

Structural imbalances – which can result from skeletal misalignments; imbalances in muscle tone from poor posture and injury or trauma from any situation which affects the musculoskeletal system.

Chemical imbalances – which could be nutritional deficiencies of vitamins, minerals, amino acids; hormone imbalances; allergies to foods and the consequences of exposure to environmental toxicity, which today includes such things as dioxins, heavy metals, pesticides, herbicides and many more.

Emotional factors – which can develop from emotional traumas and negative thought patterns.

Over time the body develops adaptive patterns to these different imbalances and stressful situations, these will often be experienced as a long list of seemingly unrelated symptoms. One of Dr. Goodheart’s early protégés was Dr Alan Beardall DC, who further developed the system of Applied Kinesiology whereby the body could display the adaptive patterns it had developed. He called this system Clinical Kinesiology and it enables the practitioner to work at a much deeper level of treatment.
