The Effects of Chiropractic Care in Adults With Subclinical Spinal Pain

The actual force applied to the patient's spine depends on the chiropractor, the patient, and the spinal location of the subluxation, the general shape of the force-time history of spinal adjustments is very consistent and the duration of the thrust is always less than 200 milliseconds.

The participants head and/or spine will be moved in ways that include passive and active movements, similar to what is done when assessing the spine by a chiropractor. The sham intervention will also include the participants moving into adjustment setup positions similar to how the chiropractor would typically set up a patient with no joint pre-loading or adjustive thrust
