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.

On p. 7, right column, the sentence "The mean average reductions in pain and disability were maintained from the end of the double-blind to the end of the open-label period up to 3 years later" is not correct. It should read "2 years" instead of "3 years".

Psychological factors are associated with the emergence and persistence of pain perception. The aim of this pilot study was to assess the psychological factors relating to pain perception in patients with chronic myofacial pain and to investigate the influence of patient information, education and physiotherapy on pain perception and functional jaw opening examined over a 6-month period. ⋯ The results show the necessity of early identification of patients with severe pain chronification and the need for psychological pain therapy.

Fig. 1 is slightly flawed as shown (the last line is missing). We enter the picture again correctly.
