Randomized Controlled Trial Multicenter Study
Short-term effects of bright light therapy in adults with chronic nonspecific back pain: a randomized controlled trial.
The present trial evaluated incorporation of bright light therapy in the treatment of chronic nonspecific back pain (CNBP). ⋯ The present randomized controlled trial shows that light therapy even in low dose could improve depressive symptoms and reduce pain intensity in CNBP patients. Further research is needed for optimizing parameters of frequency, dose, and duration of therapeutic light exposure.

Observational Study
Burden of illness associated with peripheral and central neuropathic pain among adults seeking treatment in the United States: a patient-centered evaluation.
The aim of this study was to evaluate patient-reported burden associated with peripheral and central neuropathic pain (NeP) by pain severity and NeP condition. ⋯ Subjects across NeP conditions exhibited high pain levels, which were significantly associated with poor function, compromised health status and sleep, and increased anxiety and depression. Results indicate substantial patient burden across broad NeP, particularly among subjects with severe pain.

The purpose of this study is to assess Florida physicians' attitudes and knowledge toward accessing the state's prescription drug monitoring program (PDMP). ⋯ The study revealed that a majority of participants believe that the PDMP is a useful tool for monitoring patients' controlled substance histories. More continuing education programs should be provided to Florida physicians to enhance their knowledge regarding PDMPs.

Randomized Controlled Trial
Baseline brain activity predicts response to neuromodulatory pain treatment.
The objective of this study was to examine the associations between baseline electroencephalogram (EEG)-assessed brain oscillations and subsequent response to four neuromodulatory treatments. Based on available research, we hypothesized that baseline theta oscillations would prospectively predict response to hypnotic analgesia. Analyses involving other oscillations and the other treatments (meditation, neurofeedback, and both active and sham transcranial direct current stimulation) were viewed as exploratory, given the lack of previous research examining brain oscillations as predictors of response to these other treatments. ⋯ The findings support the idea that different patients respond to different pain treatments and that between-person treatment response differences are related to brain states as measured by EEG. The results have implications for the possibility of enhancing pain treatment response by either 1) better patient/treatment matching or 2) influencing brain activity before treatment is initiated in order to prepare patients to respond. Research is needed to replicate and confirm the findings in additional samples of individuals with chronic pain.

To investigate the role of preoperative pain sensitivity and preoperative symptom severity for prediction of postoperative pain intensity after lumbar spine surgery. ⋯ The study highlights that each preoperative back pain and individual pain sensitivity could predict the different aspects of postoperative pain after lumbar surgery.
