Frank, just reading another thread posted by you, I noticed the bit about therapists attitudes to McKenzie. I have only read the the US (phys. Ther) article re: Physical Therapists....I will have to look up the others, concerning UK,which no doubt will be interesting. However I think in view of the professions evidence base and decision making up till now it is worth bearing in mind "clinical research and review of research literature ranked least important among questioned physiotherapists as rationales for choosing treatment methods". in one study -Turner and Whitfield (1997). It may be worth taking what the profession does as a whole with a pinch of salt and not evidence of the best route to take? Sam
