An instrument Chiropractic adjustment is a therapeutic procedure where a Doctor of Chiropractic uses a small, handheld instrument to deliver a quick, low force impulse to joint in the spine or other joints of the body. The goal is to restore joint mobility, reduce pain, and improve function by correcting misalignments or subluxations in the spine or other joints. This technique is great for people with osteoporosis, who have had spinal surgery or just do not like manual adjusting.
