Randomized Controlled Trial
[The impact of catastrophizing on the effect of depression on pain and functional ability : A longitudinal mediator analysis].
While the association between pain and depression is well proven, little is known about the mechanisms influencing this relationship. The cognitive distortion of catastrophizing plays a significant role in several concepts of both diseases. ⋯ Catastrophizing mediates the relationship between depression and pain as well as functional capacity; therefore, the reduction of catastrophizing thoughts and attitudes should be a focus in rehabilitation programs.

Randomized Controlled Trial Comparative Study
[Dose-finding for treatment with a transdermal fentanyl patch : Titration with oral transmucosal fentanyl citrate and morphine sulfate].
To date, no studies investigating titration with oral transmucosal fentanyl for the dose-finding of transdermal fentanyl treatment have been published. In an open randomized study 60 patients with chronic malignant (n = 39) or nonmalignant pain (n = 21), who required opioid therapy according to step three of the guidelines of the World Health Organization (WHO), were investigated. In two groups of 30 patients each titration with immediate release morphine (IRM) or oral transmucosal fentanyl citrate (OTFC) was undertaken. ⋯ Oral transmucosal fentanyl citrate can be applied for the titration of transdermal fentanyl, but it does not show any clinically relevant advantage. For example, the risk of side effects-induced drop-outs was greater in the present study. Whether the unnecessary opioid switching to treat chronic pain and breakthrough pain is advantageous with regard to minimizing conversion errors cannot be definitively answered within the scope of this study.

Randomized Controlled Trial
[Manual trigger point therapy of shoulder pain : Randomized controlled study of effectiveness].
Although chronic shoulder pain is highly prevalent and myofascial trigger points (mTrP) are thought to be found in the majority of patients with shoulder complaints, the influence on the pain mechanism remains unclear. There are only very few controlled clinical studies on the effects of manual trigger point compression therapy. ⋯ The significant improvement of PPT values in the interventional group even at sites that were not directly treated, indicates central mechanisms in pain threshold modulation induced by manual compression therapy. The weaker but still measurable effects of sham therapy might be explained by the sham modality being a hands on technique or by sufficient stimulation of the trigger point region during the diagnostics and PPT measurements.

Randomized Controlled Trial Multicenter Study
[Development and content of the behavioral therapy module of the MiSpEx intervention : Randomized, controlled trial on chronic nonspecific low back pain].
Back pain is a complex phenomenon that goes beyond a simple medical diagnosis. The aetiology and chronification of back pain can be best described as an interaction between biological, psychological, and social processes. However, to date, multimodal prevention and intervention programs for back pain that target all three aetiological factors have demonstrated limited effectiveness. ⋯ To this end, the biological elements of neuromuscular adaptation is supplemented with cognitive behavioral and psychophysiological techniques in an intervention that can be followed at home as well as in clinics, and that is suitable for all grades of pain. The efficacy of this intervention will be tested in a multicentric randomized controlled longitudinal trial (n = 714) at five time points over a period of 6 months. Here we will describe the development and the content of this new intervention.

Randomized Controlled Trial Comparative Study
[Efficacy of epidural steroid injections for chronic lumbar pain syndromes without neurological deficits : A randomized, double blind study as part of a multimodal treatment concept].
Chronic lumbar pain syndromes without neurological deficits are generated by a multitude of causes. Functional, morphological and psychosocial factors are discussed. In many cases a diseased intervertebral disc is found on radiological examination but the clinical relevance of these findings is not clear. For this study it was postulated that a diseased disc results in a local inflammatory reaction therefore causing pain and impairing treatability of patients. An epidural injection of steroids can reduce inflammation and therefore improve treatability and ultimately treatment outcome. ⋯ After the epidural injection the decrease in pain and increase in treatability was statistically significant. The mechanism of the improvement is not clear and should be examined further. The epidural injection of a steroid in this subgroup of patients did not lead to a clinical improvement in the outcome.
