So a client of mine wanted to recommend his wife to come in to the LivingRoom for Chiropractic care, he said, "You really need to go get loosened up!" I said that was great but Chiropractic may feel like it's loosening you up because it's already fired you up!
I explained that the Chiropractic adjustment is simply an accurate and considered input to the nervous system through the specific stimulation of movement receptors in the spine.
This adjustment to the spine 'fires up' the feedback from the spine to the brain which in turn 'fires up' feedback to local muscles that may have been unhappy and tight due to lack of feedback. This allows the muscles to resume a more natural tone which 'feels' looser and more comfortable. It also probably means that the muscles are then more responsive and stronger than they were before creating better performance and preventing injury.
