Chiropractic adjustment is a procedure in which trained specialists (chiropractors) use their hands or a small instrument to apply a controlled, sudden force to a spinal joint. The goal of this procedure, also known as spinal manipulation, is to improve spinal motion and improve your body's physical function

Chiropractic adjustment is safe when it's performed by someone trained and licensed to deliver chiropractic care.

During a typical chiropractic adjustment, your chiropractor places you in specific positions to treat affected areas. Often, you're positioned lying facedown on a specially designed, padded chiropractic table. The chiropractor uses his or her hands to apply a controlled, sudden force to a joint, pushing it beyond its usual range of motion. You may hear popping or cracking sounds as your chiropractor moves your joints during the treatment session.

Some people experience minor side effects for a few days after chiropractic adjustment. These may include headaches, fatigue or pain in the parts of the body that were treated

Chiropractic adjustment can be effective in treating low back pain, although much of the research done shows only a modest benefit — similar to the results of more-conventional treatments. Some studies suggest that spinal manipulation may also be effective for headaches and other spine-related conditions, such as neck pain.
