Chiropractic Adjustment is a chief form of chiropractic care that aims at improving spinal motion and improving the overall functions of your body. The physicians use either their hands or specialized tools to apply abrupt force to your spinal joint with a controlled maneuver. The procedure can last about 15-45 minutes. If it is your first chiropractic procedure, you will also have to undergo a needs assessment. Therefore, prepare to spend at least 45 minutes in the clinic.
