Conventional treatments have not slowed down the ever expanding low ba
ck pain (LBP) problem. Traditional treatment has most probably contrib
uted to the growth of the problem. Therefore, in a search for new solu
tions, 'functional restoration' has been devised. In connection with c
hronic LBP the term has been associated with a full-day program lastin
g from 3 to 5 weeks. It includes multidisciplinary treatment of patien
ts in groups with intensive physical and ergonomic training, psycholog
ical pain management, back school, as well as teaching in social/work
related issues. The key concepts are 'acceptance of the pain', 'activi
ty', 'self-responsibility', 'multidisciplinary' and 'quantitative func
tional evaluation (QFE)'. The latter is aimed so that the participants
can feel the physical improvement, encouraging them to be able to go
back to work, or at least to lead a more active life style. Several co
ntrolled studies suggest a lasting effect in terms of regaining their
ability to work and improving pain behavior for a good part of disable
d chronic LBP patients. However, it is noteworthy that randomized stud
ies seemingly show poorer results than studies not employing randomize
d controls.
