Also, it is hard to express my irritation with STOPP "Stress Test Occurring Phantom Perception". First of all, they operationalized it into "tender point exams." That's all it is. Those are controversial as to what they even represent. Maybe in the study it was meant to represent changes in pain threshold. Yeah maybe it does. Maybe it doesn't. But then you call it "Stress Test Occurring Pain Threshold Decrease"--look, it almost spells STOP. What the heck is a "phantom perception"? Translation: the observer gets to decide if the subject has "real" pain or not. (Newsflash: the word "pain" means a subjective perception, unless you are a behaviorist/solipsist). The observer apparently then gets to decide if the subject has "real" injury (for example, if exercise causes injury to nerves) or not. Instead of, you know, studying the subject to look for injury. The term seems to evoke "phantom limb pain." Phantom limb pain is pain, not a phantom. The limb is the phantom, not the pain. The pain exists in the nervous system. People who, for example, actually have limbs, do not have phantom limb pain, nor phantom pain, they have limb pain. You could have "phantom pain" if a disembodied soul had pain. Then you could surmise that "pain" does not "exist in the nervous system" but was instead, for sure, "phantom pain." Disgusting.
