Randomized Controlled Trial
Pedometer-driven Walking for Chronic Low Back Pain: A Feasibility Randomized Controlled Trial.
To evaluate the feasibility of an RCT of a pedometer-driven walking program and education/advice to remain active compared with education/advice only for treatment of chronic low back pain (CLBP). ⋯ This preliminary study demonstrated that a main RCT is feasible. EWP was safe and produced a real increase in walking; CLBP function and pain improved, and participants perceived a greater improvement in their PA levels. These improvements require confirmation in a fully powered RCT.

Obstructive sleep apnea (OSA) has become an epidemic worldwide, and OSA patients frequently present for surgery. Comorbidities such as cardiovascular disease, diabetes, hypertension, stroke, gastrointestinal disorder, metabolic syndrome, chronic pain, delirium, and pulmonary disorder increase the perioperative risk for OSA patients. ⋯ Management of acute postoperative pain in OSA patient remains complex. A comprehensive strategy is needed to reduce the complications and adverse events related to administration of analgesics and anesthetics.

Subcutaneous and Perineural Botulinum Toxin Type A For Neuropathic Pain: A Descriptive Review.
Botulinum toxin is a neurotoxin that has been widely used in chronic pain for the treatment of multiple conditions with a component of localized muscle spasm. Recent studies suggest that botulinum toxin is effective in the treatment of neuropathic pain syndromes such as postherpetic neuralgia or painful scars. ⋯ On the basis of the analysis of the reports published in the literature, it would seem that fractioned peripheral subcutaneous and perineural injections of botulinum toxin type A may be useful for the treatment of various chronic pain conditions with neuropathic component.

Comparative Study
Sensory Hyperalgesia is Characteristic of Nonspecific Arm Pain: A Comparison With Cervical Radiculopathy and Pain-Free Controls.
Nonspecific arm pain (NSAP) is a common clinical entity, the pathophysiological mechanisms of which are poorly understood. The purpose of this study was to investigate sensory profiles in individuals with nonspecific arm pain compared with cervical radiculopathy and pain-free controls. ⋯ Sensory profiles in NSAP and cervical radiculopathy differ. NSAP is characterized by widespread sensitivity to thermal and pressure pain in the absence of thermal hypoaesthesia, whereas cervical radiculopathy is characterized by the presence of thermal and vibratory hypoaesthesia as well as more localized cold and pressure pain sensitivity. The identification of widespread sensory hypersensitivity in NSAP has important implications for clinical decision making.

Multicenter Study
Long-term Results of Percutaneous Lumbar Decompression for LSS: Two-Year Outcomes.
The aim of this report was to evaluate the long-term effectiveness and safety of mild lumbar decompression for the treatment of neurogenic claudication associated with lumbar spinal stenosis. This technique uses a percutaneous dorsal approach to remove small portions of ligament and lamina, thereby restoring space and decompressing the spinal canal. ⋯ In this report of 2-year follow-up on 45 patients treated with mild percutaneous lumbar decompression, patients experienced statistically significant pain relief and improved functionality.
