A Welcome Response

A recent study performed at the University of Calgary undertook to provide scientific proof to reinforce anecdotal evidence that spinal manipulation provides beneficial effects. It made use of electromyography, which records the electrical activity of muscles by outfitting them with electrodes, as ten male subjects received spinal manipulative treatments (SMTs). It was found that significant responses occurred in all back muscles when SMTs were administered to the high and midsections of the thoracic spine. SMTs administered to the cervical spine produced responses to most muscles of the neck and back. In the lumbar spine, SMTs produced responses in all back muscles and both gluteal muscles. These, and other muscle responses, show that spinal adjustments produce discernible effects on related muscles.
