[...]does it help to introduce yet more acronyms? I have for ten years been involved in a large international study to define epidemiological criteria for these syndromes.3 Those afflicted by chronic pain, the majority, were then graced by another acronym: CPS (chronic pain syndrome).

All this is very confusing to the layman, the review officer, the judge and even the expert witness and the independent medical assessor (IPA).
