Dr. David Walther, DC, was a 1959 graduate of Palmer College of Chiropractic and one of the most prolific writer-researchers in the Kinesiology profession. Dr. Walther's writings and teachings about applied kinesiology (AK) crossed the globe, influencing thousands of Kinesiologists.
After starting practice with his father in Pueblo, Colorado, he first invited Dr. George J. Goodheart Jr. to lecture on the topic of manual muscle testing and grew fascinated with the increased possibilities for chiropractic diagnosis using Goodheart's methods.
In 1976, Dr. Walther started developing educational materials on AK. He became an avid practitioner of AK and a philosopher, researcher, encyclopedist and educator of its possibilities for patient health care.
The first text Dr. Walther wrote on AK, Applied Kinesiology – The Advanced Approach in Chiropractic, was published in 1976, and all certified teachers of AK immediately began using it as the recommended text. Programmed instruction workbooks accompanied the initial text, and Walther produced more than 10,000 slides as part of the audiovisual instruction program for AK teachers around the world. He was the primary developer of the 100-hour basic course syllabus adopted by the International College of Applied Kinesiology (ICAK).
Walther's second text, Applied Kinesiology, Volume 1 – Basic Procedures and Muscle Testing (1981), covers the basic procedures of AK and introduced the breadth of MMT procedures to the chiropractic profession and the world. Applied Kinesiology,Volume II – Head, Neck, and Jaw Pain and Dysfunction, The Stomatognathic System (1983) was his third book on AK, covering the cranialsacral primary respiratory system. The use of the MMT in cranial therapy added another examination tool for the discovery of disorders in this subtle and complex system.
Dr. Walther also wrote chapters in several dental textbooks on the examination and treatment of the stomatognathic system, which includes the cranium, temporomandibular joint and cervical spine, how these structures influence the rest of the body and how the rest of the body influences it. This text is used by many dentists and has helped develop closer relationships between dentists and chiropractors.
Dr. Walther wrote each of these seminal texts while maintaining a thriving practice in Pueblo. At the time of his passing, he was working on three additional textbooks in the series: Volume III, on the meridian system; Volume IV, on orthopedic conditions; and Volume V, on systemic conditions.
Because each textbook took him several years to complete, Walther's Applied Kinesiology: Synopsis, covering each of the subject areas in the texts, was published in 1988, with a second edition in 2000. These textbooks on AK chiropractic technique have been translated into Italian, Korean, French, German and Japanese.
