Back pain is one of the most common causes of disability in industrialized nations. Despite this, the variables that contribute to disability are not well understood and optimal measurement strategies of disability have not yet been determined. The present study sought to comprehensively assess the strongest predictors of physical activity as a proxy for disability. ⋯ Subsequent analyses showed that pain sensitivity, fear avoidance, and solicitous spousal responses account for a significant amount of the variance in physical activity. These findings suggest that external sources of reinforcement or punishment may serve to influence physical behavior beyond that of internal cues such as fear avoidance or pain. Implications for treatment are discussed, including the potential benefits of specifically incorporating the patient's sources of operant reinforcement or punishment into treatment.

Fibromyalgia (FM) is the second most common cause of visits to rheumatologists after osteoarthritis, and may be difficult to diagnose in many patients. It is associated with various rheumatic disorders such as rheumatoid arthritis, spondyloarthropathies (SpA) and connective tissue disease (CTD), and a late diagnosis or misdiagnosis is a common and underestimated problem. ⋯ The findings of this study suggest that, although FM is a wellknown clinical entity, differential diagnosis with SpA, CTD and inflammatory arthritis can still be a challenge for rheumatologists and general practitioners.

Chronic pain is inadequately treated in many patients, which has led clinicians and researchers to investigate new indications for existing medications with pain-relieving or adjuvant properties. These medications are known as coanalgesics. ⋯ An update on emergent treatments and uses is also presented. The goals of this article are to highlight coanalgesic treatment options that are currently available for patients with chronic pain as well as provide guidelines for their use in clinical practice.

Spinal cord stimulation (SCS) is an established treatment option for chronic pain. Prior to permanent implantation, temporary trials are performed to evaluate the SCS treatment. Currently there are multiple manufacturers with varying fundamental differences in delivery and resultant paresthesias. However, trials are typically limited to one manufacturer for the patient to evaluate. ⋯ The OMG Connector offers patients another opportunity to better access the available treatment options during the SCS trial period.

Chronic widespread pain (CWP) is a common symptom within the community, and may be part of or arise as a result of various diseases or conditions. Fibromyalgia (FM) is probably the most common and best known disease whose cardinal symptom is CWP. Many authors, however, indistinctively describe pain as 'widespread', 'diffuse' or 'generalised', and this may lead to misunderstandings about true clinical or scientific significance. ⋯ There is no clear-cut evidence of FM or CWP due to infections or vaccinations, no correlations with persistent infection, and no proven relationship between infection, antimicrobial therapies and pain improvement. A higher prevalence of FM and chronic pain has been found in patients with Lyme disease, and HIV or HCV infection, and, perhaps, also in patients with mycoplasmas, HBV, HTLV I, and parvovirus B19 infections. Some unconfirmed evidence and case reports suggest that vaccinations may trigger FM or chronic pain.
