I am a Chiropractor, and I use Graston on nearly all my patient's. It is a process though, and many practioner's do it differently. In my clinical experience, sometimes Graston is too aggressive to use right away, and must be built up to it. I personally believe when using Graston, the site of pain should not be the main focus, but rather entire fascial lines need to be addressed. Usually when people present with an issue, the site of pain is not the culprit, so when the local problem is the focus people do not get well and have chronic injuries. When entire fascial lines are addressed, people get much better results.
Another thing that needs to be remembered is consistency of care. If a person only goes once or twice, they probably wont get better. People should be seen multiple times a week for a few weeks, and then care can be decreased. Hope this helps
