Mild, moderate, and severe asymmetries are identified by color bars. It must be remembered that since vasomotor activity should be a dynamic process, the levels of asymmetry will change from session to session unless a chronic subluxation is present. Even though the levels change, a patient with acute or subacute subluxation will usually have approximately the same number of levels out of range, although the levels themselves may change. However, temperature patterns on a patient change from moment to moment unless chronic subluxation is present. This may incorrectly lead the examiner to believe that the instrument or procedure is not reproducible.
Reproducible readings indicate chronic subluxation.
This is NOT a normal or desirable state of affairs. In acute and subacute subluxations, there will be levels out of range, but the pattern will vary. In chronic subluxations, the pattern will be fixed, and there will be levels out of range. Levels of asymmetry often do not relate to the level of primary subluxation. Thermal patterns measure autonomic activity.
