A subluxation refers to a misaligned vertebral bone in the spine. This occurs when one or more vertebrae are not properly aligned, causing irritation or compression of nearby nerves. It can result in pain, limited mobility, and other symptoms. Correcting the misalignment is typically done through chiropractic adjustments or other manual therapies. A pinched nerve along the spine may be a result of a subluxation, but it is not the same thing. "Slouching" is not a term used to describe a subluxation.
