Hi Jeremy,

The pain definition by IASP might help, " An unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage". 

From what I understand, so even bumping your head into a door frame or acute pain has an emotional component.  As they say  " no brain, no pain". So I am not sure if we can tease out the emotional from the sensory/physiological. 

Check Lorimer Moseley when you get a chance.

Dear List Members,

Within the context of a trial or systematic review, is change in pain (for example with a visual analog scale): (a) physical outcome, (b) psychological outcome, or (c) both.neither?

I am aware that many causes of pain (such as bumping my head into a low door frame) are purely physical. What I am interested in is whether pain as an outcome measured by a visual analog scale itself is physical, psychological, or both/neither.

I’m specifically interested in what the scientific consensus is or, better, whether there is evidence of some kind that could resolve this.

Thanks in advance,

Jeremy
