Multicenter Study
Patients With Neck Pain are Less Likely to Improve if They Experience Poor Sleep Quality: A Prospective Study in Routine Practice.
To assess whether sleep quality (SQ) at baseline is associated with improvement in pain and disability at 3 months. ⋯ NP is less likely to improve in patients with poorer SQ, irrespective of age, sex, catastrophizing, depression, or treatments prescribed for NP. Future studies should confirm these results with more severely impaired patients.

Predictive Factors Associated with Success and Failure for Calmare (Scrambler) Therapy: A Multi-Center Analysis.
Calmare (Scrambler) therapy is a novel therapeutic modality that purports to provide pain relief by "scrambling" afferent pain signals and replacing them with "non-pain" information through conventional lines of neural transmission. The goal of this study is to identify which factors are associated with treatment outcome for Calmare therapy. ⋯ A neuropathic or mixed neuropathic-nociceptive pain condition was associated with a positive treatment outcome. Investigators should consider these findings when developing selection criteria in clinical trials designed to determine the efficacy of Calmare therapy.
