You might have seen videos of patients lying on a special table and a chiropractor doing hand manipulations to help them with their pain. Often times, sounds may be heard as a result of an adjusment, releasing nerve pressure due to a subluxation. A subluxation is a misalignment of the spine causing nerve interference, in return, the chiropractor tries to restore the proper communication between the brain and spine by removing the interference resulting in improved mobility, decreased pain and increased function of the spine and corresponding nerve.
