Thank you Dr Gerry for the excellent information. At this point I
have access to a laser that can adjust power from 10-40mw and is
650nm. No frequency adjustment though. It would be nice to have that
feature but it is out of my budget constraints for now. Would this be
adequit for inducing deep tissue healing, surface healing, and
accupressure point stimulation?
