Psychological factors are assumed to predict persistent or recurrent musculoskeletal pain. The influence of psychological factors in patients with low-back pain (LBP) or shoulder pain was explored to study whether there is similarity regarding the factors that predict persisting pain and disability. ⋯ Psychological factors, with the exception of fear-avoidance beliefs, are more strongly associated with persistent pain and disability in patients with LBP than in those with shoulder pain. This seems to indicate that in a primary care population the influence of psychological factors on outcome may vary across patients with different types of pain.

Age as a predicting factor in the therapy outcome of multidisciplinary treatment of patients with chronic low back pain--a prospective longitudinal clinical study in 405 patients.
This prospective longitudinal clinical study evaluates the prognostic value of age in the therapy outcome of patients with chronic low back pain treated with a multidisciplinary therapy. Four hundred five patients with chronic low back pain for 3 months or longer and a corresponding sick leave for longer than 6 weeks underwent a 3-week standardized multidisciplinary therapy. Patients were assigned into three groups of age with comparable baseline values at T0. ⋯ In the total group, the back-to-work rate was 61.7%. At the final follow-up, there were significantly better results in terms of functional capacity and pain level in younger patients, whereas back-to-work rate and satisfaction with therapy did not show a significant difference between the groups analysed. According to the results of this study, older patients with chronic low back pain also derive significant benefit from a multidisciplinary treatment strategy, although in some outcome criteria results were inferior to those obtained in younger patients.

Randomized Controlled Trial
A pilot study of the effects of high-intensity aerobic exercise versus passive interventions on pain, disability, psychological strain, and serum cortisol concentrations in people with chronic low back pain.
Given the complex nature of chronic pain, the effects of high-intensity aerobic exercise on pain, disability, psychological strain, and serum cortisol concentrations in people with chronic low back pain were investigated. ⋯ Regular high-intensity aerobic exercise alleviated pain, disability, and psychological strain in subjects with chronic low back pain but did not improve serum cortisol concentrations.

Comparative Study
Pain behavior and the development of pain-related disability: the importance of guarding.
To examine prospectively the association between the 4 categories of objectively assessed pain behavior and various disability outcomes. In the present study, relationships among the 4 categories of pain behavior and various disability-related outcomes were examined. ⋯ Guarding behavior may play a role in the transition from acute to chronic pain. The findings underscore the multidimensional nature of pain behavior and suggest that there is value in examining overt pain behaviors in prospective studies of the development of chronic occupational pain disability.

Facet syndrome is persistent low back pain that might be treated with some surgical interventions. The target of surgical techniques is the transverse process bases where the medial nerve branches innervated the facet. However, highly variable success rates have been demonstrated in different series. ⋯ The dorsal surface of the facet capsule might be a more preferable target for facet denervation.
