There are well over 100 types of spinal adjustment techniques used by chiropractors throughout the world. Typically, one chiropractor may utilize 8 to 10 different approaches in their practice. The common goal of most chiropractic adjustment is to restore or to enhance joint function, with the general goals of resolving joint inflammation and reducing pain. Some approaches use some force (spinal manipulation), while others are more gentle (spinal mobilization).
Not everyone needs an adjustments. While it may sound scary, the audible sound that is released from the spine following a spinal adjustment is nothing but the sound of gas escaping from within an inflamed joint capsule. The adjustment acts on the joints in the same manner as when you open a compressed champagne bottle (compressed inflamed joint capsule), leading to the release of an audible sound and a particular outcome which is in the case of the champagne's example, an outpouring of liquid (a now relaxed joint capsule). The adjustments induce immediate release of endorphin and anti-inflammatory molecules around the affected joint, yielding a sensation of relief and better segmental mobility.
