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.

Randomized Controlled Trial Multicenter Study Comparative Study
Effectiveness and Safety of Transdermal Buprenorphine Versus Sustained-Release Tramadol in Patients with Moderate to Severe Musculoskeletal Pain: An 8-Week, Randomized, Double Blind, Double Dummy, Multi-Center, Active-controlled, Non-inferiority Study.
The aim of this noninferiority study was to investigate clinical effectiveness and safety of buprenorphine transdermal system (BTDS) in patients with moderate to severe musculoskeletal pain inadequately controlled with nonsteroidal anti-inflammatory drugs, compared with sustained-release tramadol tablets. ⋯ Our results suggest that BTDS is a good therapeutic option for patients experiencing chronic musculoskeletal pain of moderate to severe intensity that is insufficiently controlled by nonsteroidal anti-inflammatory drugs.

Multicenter Study Comparative Study
A Two Center Comparative Study on Tonic Versus Burst Spinal Cord Stimulation: Amount of Responders and Amount of Pain Suppression.
Spinal cord stimulation is a safe and effective procedure applied for medically intractable neuropathic pain and failed back surgery syndrome. Recently, a novel stimulation paradigm was developed, called burst stimulation consisting of intermittent packets of closely spaced high-frequency stimuli. The design consists of 40 Hz burst mode with 5 spikes at 500 Hz per burst, with a pulse width of 1 ms and 1 ms interspike interval delivered in constant current mode. ⋯ Burst seems to be significantly better than tonic stimulation. It can rescue an important amount of nonresponders to tonic stimulation and can further improve pain suppression in responders to tonic stimulation.

Randomized Controlled Trial Multicenter Study
A Randomized, Placebo-controlled Trial of the Analgesic Efficacy and Safety of the p38 MAP Kinase Inhibitor, Losmapimod, in Patients With Neuropathic Pain From Lumbosacral Radiculopathy.
Preclinical studies have demonstrated involvement of p38 mitogen-activated protein kinase signaling pathways in the development of persistent pain after peripheral nerve injury. A double-blind, randomized, placebo-controlled study was undertaken to evaluate the analgesic efficacy of losmapimod (GW856553), a novel p38α/β inhibitor, in patients with chronic neuropathic pain due to lumbosacral radiculopathy. ⋯ Losmapimod could not be differentiated from placebo in terms of analgesia. The lack of response could reflect insufficient losmapimod levels in the spinal cord or differences between lumbosacral radiculopathy and animal models of neuropathic pain.

Randomized Controlled Trial Multicenter Study
The Effect of Neck-specific Exercise with, or without a Behavioral Approach, on Pain, Disability and Self-efficacy in Chronic Whiplash-associated Disorders: A Randomized Clinical Trial.
The aim of this study was to compare the effect on self-rated pain, disability, and self-efficacy of 3 interventions for the management of chronic whiplash-associated disorders: physiotherapist-led neck-specific exercise (NSE), physiotherapist-led NSE with the addition of a behavioral approach, or Prescription of Physical Activity (PPA). ⋯ NSE resulted in superior outcomes compared with PPA in this study, but the observed benefits of adding a behavioral approach to the implementation of exercise in this study were inconclusive.
