When using the Gonstead Chiropractic Technique, five criteria are used to detect the presence of vertebral subluxation.

1: Visualization - Chiropractors are experts at looking subtle changes in posture and movement that could indicate any spinal problems.

2: Instrumentation - The nervoscope is an instrument used to detect uneven distributions of heat along the spine. These uneven areas of heat can be an indication of inflammation and nerve pressure.

3: Static Palpation - Static palpation is performed when the spine is in a stationary position. A process where the chiropractor feels the patient's spine for the presence of any abnormal texture or tightness in the muscles or various tissues in the back.

4 - Motion Palpation - Motion Palpation is examination of the spine while it is in movement. This allows the chiropractor to assess how easily the spine moves in various directions.

5 - X-Ray Analysis - X-Rays provide your chiropractor with a visual image of your entire spine structure. These full spine radiographs are helpful in evaluating posture, vertebral misalignments, joint and disc integrity, and other important information.
