Randomized Controlled Trial
The effects of music intervention in the management of chronic pain: a single-blind, randomized, controlled trial.
A music intervention method in the management of pain was recently developed while taking account of recommendations in the scientific literature. The objective of this study was to assess the usefulness of this music intervention to the management of patients with chronic pain. ⋯ These results confirm the value of music intervention to the management of chronic pain and anxiety/depression. This music intervention method appears to be useful in managing chronic pain as it enables a significant reduction in the consumption of medication.

The objective of the study was to report the evidence for effectiveness of different self-management course characteristics and components for chronic musculoskeletal pain. ⋯ Serious consideration should be given to the development of short (<8 weeks) group and healthcare professional-delivered interventions but more research is required to establish the most effective and cost-effective course components.

Review
Effect of immunomodulating medications in complex regional pain syndrome: a systematic review.
Different mechanisms are involved in a complex network of interactions resulting in the painful and impairing disorder, complex regional pain syndrome (CRPS). There is convincing evidence that inflammation plays a pivotal role in the pathophysiology of CRPS. Immunomodulating medication reduces the manifestation of inflammation by acting on the mediators of inflammation. Therefore, as inflammation is involved in the pathophysiology of CRPS, immunomodulating medication in CRPS patients may prove beneficial. ⋯ Theoretically, the use of immunomodulating medication could counteract the ongoing inflammation and might be an important step in improving a disabled hand or foot, leading to further recovery. However, more high-quality intervention studies are needed.

The relationship between chronic pain and sleep disturbances is not yet fully understood, despite much evidence linking them. Polysomnography is the gold standard for assessing sleep architecture, and in this naturalistic study, we wanted to compare both macrostructure and microstructure sleep variables in older chronic pain patients with healthy older persons using polysomnography. ⋯ The chronic pain group spent significantly longer time in bed and had poorer sleep than the control group in terms of sleep onset latency, sleep latency to N2, sleep efficiency, wake time after sleep onset, and number of awakenings. However, sleep duration and time spent in each sleep stage did not differ between the 2 groups. The composition of power spectrum frequencies revealed that older people with chronic pain have lower intensity in the δ frequencies (0.5 to 1.99 Hz and 2 to 4 Hz) throughout the whole night, especially in the first 6 hours. The findings are in accordance with the idea that the quality of sleep while in chronic pain is particularly characterized by difficulties with the wake-sleep transition and a lower intensity of the deep restorative sleep throughout the night.

In 1980 the Waddell score, consisting of 8 non-organic or behavioural signs, was developed to measure illness behaviour in patients with low back pain. There is some debate about whether the Waddell score is a valid screening instrument for illness behaviour and psychological distress, or whether it merely reflects elevated pain levels and diminished functional physical capacities. ⋯ Most of our challenging a priori hypotheses were accepted, and the Waddell score was found to have satisfactory cross-sectional construct validity. However, the presence of Waddell signs does not indicate exactly what the specific problems are and must therefore be conceptualized and understood in the total clinical picture of the patient. The association between the Waddell score and measures from different domains is weak. The Waddell score cannot be regarded as a straightforward psychological "screener".
