Randomized Controlled Trial Comparative Study
[Effects of interdisciplinary functional restoration treatment with cognitive behavior therapy in patients with chronic back pain : Healthcare research in the context of selective contracts].
The efficacy of functional restoration programs for the treatment of chronic back pain is well documented. Nevertheless, there are only a few such centres in Germany and few trials have been conducted in German-speaking regions to demonstrate that implementing such programs in everyday clinical settings with large numbers of patients is just as effective as in a research setting. The present study examined whether the positive effects of such programs can also be observed in the clinically relevant context of a standardized day clinic treatment regimen. ⋯ In both cities significant and long-term improvements in back pain, pain-related impairment and degree of chronification were observed, as well as a high return-to-work rate after treatment. Hence, the quality of such programs was also confirmed for a large patient population.

Controlled Clinical Trial
[Evaluation of the German new back school : Pain-related and psychological characteristics].
Results related to the outcome of the classical back schools are inconsistent. Accordingly, a reformulation of the program integrating psychological and social aspects was performed as a necessary step for the development of the new back school in Germany. The aim of this study was to assess the effectiveness and sustainability of the new back school in subjects with non-specific back pain in the prevention setting. ⋯ On the basis of the sample studied, the new back school proved to be an effective treatment for short and long-term reduction of pain-related stress and associated psychological aspects. Maladaptive, passive coping strategies and higher depression scores were associated with a higher probability of success in terms of pain reduction and functional improvement.

The fear-avoidance model (FAM) has gained widespread acceptance as a conceptual framework predicting chronic pain development. However, there is still a high amount of unexplained variance in the prediction of outcome variables. This study aimed to test depression as a mediator of prospective links between the FAM variables pain intensity, pain-related fear, avoidance behavior and disability in order to achieve a better prediction of model variables. ⋯ The findings provide support for additional consideration of depressive symptoms to obtain a better understanding of prospective associations between FAM variables. The findings indicate that in the treatment of chronic back pain following a multiple target approach to reduce pain, pain-related fear and avoidance behavior and also depressive symptoms should be considered.

Prevalence of the fibromyalgia phenotype in patients with spine pain presenting to a tertiary care pain clinic and the potential treatment implications.
Injections for spinal pain have high failure rates, emphasizing the importance of patient selection. It is possible that detecting the presence of a fibromyalgia (FM)-like phenotype could aid in prediction, because in these individuals a peripheral injection would not address pain due to alterations in central neurotransmission. We undertook this study to test the hypothesis that patients who have spine pain meeting survey criteria for FM would be phenotypically distinct from those who do not. ⋯ Using the FM criteria and severity scales, we demonstrated profound phenotypic differences in a population of patients with spine pain. Although centralized pain cannot be confirmed with a self-report instrument alone, the pathophysiology of FM may help explain a portion of the variability of responses to spine interventions.

If persons at risk of developing chronic pain could be identified early in a pain episode, treatment could be tailored on the basis of risk. Responses to psychophysical tests differ in persons with chronic pain vs pain-free controls and thus appear promising as indicators of susceptibility to chronic pain. In a cohort of 157 patients making their first primary care visit during a back pain episode, we explored the relationships of psychophysical test responses (pressure pain thresholds at low back and thenar sites, cold pressor pain ratings, conditioned pain modulation, and mechanical temporal summation) to baseline measures of pain and psychological distress and assessed whether test responses predicted clinically significant back pain 4 months later. Examiner-standardized pressure pain thresholds were significantly (P < .05) correlated with baseline back pain severity and diffuseness of bodily pain (Pearson correlations = -.21 to -.35). Lower baseline pressure pain thresholds significantly predicted back pain at 4 months (odds ratio [95% confidence interval]: low back, .66 [.44, .96]; thenar, .62 [.40, .92]); however, after controlling for participant age and sex, these associations were no longer significant. Cold pressor pain, conditioned pain modulation, and mechanical temporal summation were not significant predictors of 4-month back pain in either model. ⋯ Some psychophysical test responses have been found to differ in persons with chronic pain vs pain-free controls. In this prospective study, psychophysical test responses had limited utility for predicting which primary care back pain patients would have clinically significant chronic pain 4 months later.
