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.

Chronic abdominal and flank pain can be multifactorial and difficult to treat. Loin pain hematuria syndrome (LPHS) is a rare clinical cause of chronic abdominal and flank pain and is a diagnosis of exclusion with limited treatment options, ranging from medications to renal autotransplantation or even nephrectomy in resistant cases. ⋯ LPHS is a difficult clinical scenario to diagnose and treat. Conservative options are often unsuccessful, but the more extreme interventions such as renal autotransplantation and nephrectomies are invasive and not always effective. In this case report, we describe the novel use of PRF to the splanchnic nerves as an alternative treatment modality for patients with LPHS.Although the exact mechanism of action of PRF on nerve tissue is unclear, its indication in pain management requires further research and discussion. Our patient experienced substantial and sustained relief of his flank pain. PRF may be a viable option for patients with LPHS.

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.

Randomized Controlled Trial
Transcranial Direct Current Stimulation (tDCS) Reduces Postsurgical Opioid Consumption in Total Knee Arthroplasty (TKA).
Although pain is often a symptom that precedes total knee arthroplasty (TKA), the procedure itself is associated with considerable postoperative pain lasting days to weeks. Postoperative pain control is an important factor in determining recovery time, hospital length of stay, and rehabilitation success. Several brain stimulation technologies including transcranial direct current stimulation (tDCS) have demonstrated promise as treatments for a variety of pain conditions. The present study examined the effects of 4 sessions of tDCS on post-TKA pain and opioid consumption. ⋯ Results from this pilot feasibility study suggest that tDCS may be able to reduce post-TKA opioid requirements. Although these results are preliminary, the data support further research in the area of adjunctive cortical stimulation in the management of postsurgical pain.

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.
