Chiropractic Manipulative Technique (abbreviated CMT), this form of treatment utilizes an external force from the doctor to the patient’s body. The act of manipulating a joint, or adjusting, is inherently specific for each application. Each adjustment is unique and can vary from region to region, as well as patient to patient, depending on the case at hand. Identifying the right level and location to apply force is a valuable chiropractic skill. This skill is refined through hundreds of hours of practice on the behalf of the chiropractor.
There are hundreds of different types of adjustments and several dozen different styles, all with different uses and different postures. This allows for each practitioner to have a different approach to patient treatment styles, while still obtaining the same effect.
Most patients recognize the signature “crack” or “pop” that is audible when they are being adjusted. This sound is properly known as a “cavitation” and is caused by the release of nitrogen gas from the joint capsule of the joint that is being manipulated. This sound is harmless, and is not a required “sound” to a successful adjustment. Some patients have very audible cavitations, while others make no noise when they are manipulated. The nitrogen gas is a natural byproduct of the production of the fluid within the joint and then the containing joint capsule is stretched, the smaller gas bubbles join into a larger one then collapse. Given enough time, the nitrogen gas permeates the fluid once again. (Approximately 20 minutes)
The purpose of the adjustment is to restore motion to the restricted joint. The restriction can be caused by a large variety of different causes. Some joints restrict due to arthritis, some are due to poor movement patterns, trauma, over/under active muscular activity and occasionally a vacuum like phenomenon between the ends of the joints.
Dr. Herrington has learned several different styles of manipulation and utilizes each of them depending on the situation. Having previous experience with Diversified, Gonstead, Activator, SOT and Cox styles of adjusting, allowed for Dr. Herrington to alter his treatment styles for each individual patient.
