Community Perspectives on Patient Credibility and Provider Burden in the Treatment of Chronic Pain.
This study examined factors influencing lay perceptions of a provider's clinical burden in providing care to a person with chronic pain. ⋯ The lay public is skeptical of chronic pain that is not supported by medical evidence or is reported at high levels of severity, raising concerns about psychosocial complications and drug seeking and expectations of higher burden of care. Such negative stereotypes can pose obstacles to people seeking necessary care if they or others develop a chronic pain condition.

Specific Electroencephalographic Signatures for Pain and Descending Pain Inhibitory System in Spinal Cord Injury.
The pain related to spinal cord injury (SCI) is difficult to treat, and it is associated with significant morbidity. One aspect to improve therapeutics is to explore markers of pain and its correlates in SCI. ⋯ Our results confirm and provide additional data on the relationship between decreased alpha and beta frequencies and higher pain levels. One important finding, though, was a specific and different EEG signature for the descending inhibitory pain system, as we showed that increased theta EEG power is related to decreased CPM efficiency; suggesting that, although low CPM efficiency plays a major role in pain in these participants, it does seem to be associated with a specific oscillatory brain rhythm different from clinical pain. These findings have significant implications for future research on EEG-based biomarkers of pain in post-SCI and new interventions as neurofeedback to manage pain in this population.

Can Patient Expectations Modulate the Short-Term Effects of Dry Needling on Sensitivity Outcomes in Patients with Mechanical Neck Pain? A Randomised Clinical Trial.
Dry needling is commonly used for the management of patients with musculoskeletal pain. However, the effects of patient expectations are uncertain. Our aim was to determine the effect of patient expectations on short-term clinical outcomes after the application of a single session of dry needling in individuals with neck pain. ⋯ This study did not find a significant effect of predicted patient expectations on the short-term effects of dry needling on pain intensity and pressure pain thresholds in people with mechanical neck pain.
