The chiropractic adjustment is a gentle procedure of joint manipulation which chiropractors spend years mastering. The entire goal of an adjustment is to eliminate the joint dysfunction complex, also known as a subluxation, by restoring motion into a locked joint. This is so important because a subluxation results in tight muscles in that area and widespread symptoms throughout your entire body. Some of the causes of subluxations are: trauma (a car accident, fall, etc.), bad postural habits (slouching, poor work ergonomics, etc.), poor lifestyle choices (smoking, poor nutrition, too much caffeine, not exercising, etc.), and emotional stress (fast pace lifestyle, bad attitude, etc.). Only a chiropractor can restore motion into a locked joint using the adjustment, but it is up to you to change whatever habits may be causing them lock up in the first place.
