Chiropractic adjustments usually involve a gentle but quick thrust. This thrust adds motion to spinal joints that aren't moving correctly or may be “stuck”. Our dkb chiropractor will usually use his hands for an adjustment, although, some methods use a special instrument or a special table to help with the process. The way an adjustment is delivered will be different for everyone depending on their particular situation, age and condition. A “popping” or “cracking” sound is often heard in relation to a chiropractic adjustment. This is a harmless side-effect of moving the joints – the sound is produced by gas formed in the joint and sounds similar to a bottle of champagne being opened.
