Randomized Controlled Trial
Psychobiological correlates of improved mental health in patients with musculoskeletal pain after a mindfulness-based pain management program.
Mindfulness-based pain management programs (MBPMs) aim to improve mental and physical health in individuals with chronic pain. In this study, we investigated whether improvement in mental health might require (1) reduction in the sensory pain experience and brain correlates of that experience, and/or (2) improved perceptions of the controllability of pain and corresponding brain activity related to cognitive control and emotional regulation. ⋯ Increased activity in cognitive control regions of the brain during pain anticipation related to improved mental health and perceived control over pain, but not to decreased pain experience. Greater perceived control may therefore result from improved regulation of the emotional response to pain.

Comparative Study
Lumbar muscle dysfunction during remission of unilateral recurrent nonspecific low-back pain: evaluation with muscle functional MRI.
After cessation of a low-back pain (LBP) episode, alterations in trunk muscle behavior, despite recovery from pain, have been hypothesized to play a pathogenic role in the recurrence of LBP. This study aimed to identify the presence of lumbar muscle dysfunction during the remission of recurrent LBP, while performing a low-load trunk-extension movement. ⋯ Lower T2-rest values have been suggested to correlate with a conversion of the multifidus' fiber typing toward the glycolytic muscle spectrum. Elevated T2 shifts correspond with increased levels of metabolic activity in the multifidus in the LBP group, for which several hypotheses can be put forward. Taken together, these findings provide evidence of concurrent alterations in the multifidus structure and activity in individuals with unilateral recurrent LBP, despite being pain free and functionally recovered.

Randomized Controlled Trial Comparative Study
Randomized-controlled trial comparing yoga and home-based exercise for chronic neck pain.
Chronic neck pain is a significant public health problem with only very few evidence-based treatment options. There is growing evidence for the effectiveness of yoga for relieving musculoskeletal disorders. The aim of this study was to evaluate the effect of Iyengar yoga compared with exercise on chronic nonspecific neck pain. ⋯ Yoga was more effective in relieving chronic nonspecific neck pain than a home-based exercise program. Yoga reduced neck pain intensity and disability and improved health-related quality of life. Moreover, yoga seems to influence the functional status of neck muscles, as indicated by improvement of physiological measures of neck pain.

Randomized Controlled Trial
Improved quality of life, working ability, and patient satisfaction after a pretreatment multimodal assessment method in patients with mixed chronic muscular pain: a randomized-controlled study.
To investigate whether a pretreatment multimodal (MM) assessment of patients with chronic muscular pain has an impact on treatment outcome. ⋯ Patients who underwent an MM assessment before treatment in comparison with patients receiving routine multidisciplinary assessment improved QOL, working ability, and were also significantly more satisfied. This result indicates that MM pretreatment assessment could be advantageous in the selection of patients for suitable rehabilitation treatment in a primary care setting, and also be used to prepare patients for future rehabilitation.
