Qualitative study on chiropractic patients' personal perception of the audible release and cavitation

Patients do not need to have a deep understanding of the mechanisms for the sound they hear. The majority of the patients associate the crack with a physical feeling of release; therefore they assume that the sound is proof of a well-achieved adjustment. Nevertheless, patients do not discard the therapeutic benefit of an adjustment that did not achieve the audible release. This appears to be due to their past experiences and their trust in the chiropractor.
