Chiropractic adjustments involve the application of a quick but gentle corrective force into the "subluxated" spinal vertebrae. The adjustment can be delivered manually through the hands or can be applied through the use of a specialized tool (Activator). Subluxations generally require multiple treatments or adjustments for complete normalization to occur. Similar to straightening teeth, correcting malfunctioning and misaligned vertebrae requires time for the tissues to accept this new position as "normal".
