Chiropractic adjustments help restore proper mechanics to the spine or the joint being adjusted.

A Spine Journal study was “the first to measure facet gapping during cervical manipulation on live humans”.

The results demonstrate that:

• Target and adjacent motion segments undergo facet joint gapping (0.9 mm ± 0.4mm) during manipulation.
• Intervertebral range of motion is increased (8-13 degrees) in all three planes of motion after manipulation.
• Pain score improved from 3.7±1.2 before manipulation to 2.0±1.4 after manipulation.
