A chiropractic adjustment is a specific force, applied in a specific direction, to a specific spinal joint. It is virtually impossible to adjust oneself with the precision needed to make an accurate spinal correction.
It is possible to turn or bend or twist in certain ways to create “popping” sounds, like the sound that sometimes accompanies a chiropractic adjustment. Unfortunately, this type of joint manipulation is usually counterproductive, often making an already unstable area of the spine even more unstable. Adjusting the spine is for professionals, so don’t try this at home kids!
