Validity and reliability of a back pain questionnaire. ⋯ The study showed that the psychometric properties of the original QDS have been preserved when translated into Arabic and can be used to measure disability in Arabic societies.

Randomized Controlled Trial
Brain networks predicting placebo analgesia in a clinical trial for chronic back pain.
A fundamental question for placebo research is whether such responses are a predisposition, quantifiable by brain characteristics. We examine this issue in chronic back pain (CBP) patients who participated in a double-blind brain imaging (functional magnetic resonance imaging) clinical trial. We recently reported that when the 30 CBP participants were treated, for 2 weeks, with topical analgesic or no drug patches, pain and brain activity decreased independently of treatment type and thus were attributed to placebo responses. ⋯ Additionally, by means of frequency domain contrasts, we observe that at baseline, left dorsolateral prefrontal cortex high-frequency oscillations also predicted treatment outcomes and identified an additional set of functional connections distinguishing treatment outcomes. Combining medial and lateral prefrontal functional connections, we observe a statistically higher accuracy (0.9) for predicting posttreatment groups. These findings indicate that placebo response can be identified a priori at least in CBP, and that neuronal population interactions between prefrontal cognitive and pain processing regions predetermine the probability of placebo response in the clinical setting.

Multicenter Study Controlled Clinical Trial
["Back pain coach". A project for patients with back pain].
Back pain is a challenge for case management but is a health insurance fund (HIF) that identifies high risk patients and includes them in a back pain assessment and a multimodal program cost-effective? ⋯ The HIF was responsible for the study investment and project partners shared the training of the HIF regional case managers.
