There is a subtle difference between tenderpoints and trigger point.... tenderpoints are points that are sore upon touch and DO NOT refer pain to other areas of the body. Trigger points are places that refer pain (other than pain at the site , I believe) to ANOTHER part of the body. Dr Jones, the authority on tenderpoints, believed tenderpoints to be a viscerosomatic reflex, example being a peptic ulcer eliciting a dysfunction at T5-T9. The author on triggerpoints (I cant remember the name, d'oh!) believed the triggerpoints to be the MAIN pathology. Namely, the triggerpoints can be either a viscerosomatic or somatovisceral reflex, to just use the same example as above- she believed that if you treat the triggerpoint the peptic ulcer would go away. How the treatments differ, I really have no idea, this was just the meat behind the naming.........
