Psychological research and chronic low back pain: a stand-still or breakthrough?
Some of the main psychological research topics concerning chronic low back pain (CLBP) are critically discussed. These topics include: 1. research aimed at describing a specific low back pain personality profile, 2. research into the predictability of therapy results on the basis of psychological assessment, and 3. outcome research of psychologically-oriented treatment for CLBP. It is concluded that these topics provide little insight into the role of psychological factors in the development and maintenance of CLBP. Based on the few empirical studies available, some new and promising directions for future research are proposed, aimed at gaining a better insight into the CLBP syndrome itself. Discussed are: 1. Risk factors in the transition from acute to chronic LBP, 2. the deviant sensitivity to acute, experimental pain stimuli of CLBP patients, 3. the relationship between CLBP behavior and psychophysiologic variables, 4. determinants of CLBP behavior, with special attention to endurance, 5. the deviant processing of proprioceptive stimuli, and 6. the implementation for chronic pain of the unpredictability and uncontrollability paradigms. The emphasis in the presentation of these new topics is more on raising questions than on answering them.
