Randomized Controlled Trial
Effects of transforaminal balloon treatment in patients with lumbar foraminal stenosis: a randomized, controlled, double-blind trial.
Lumbar spinal stenosis is a common condition in the elderly. Although balloon treatment is a well-known therapeutic method in specific pain conditions, applying the balloon treatment in patients with lumbar spinal stenosis is not yet well established. ⋯ Transforaminal balloon treatment leads to both significant pain relief and functional improvement in a subset of patients with refractory spinal stenosis. INSTITUTIONAL REVIEW: This study was approved by the Institutional Review Board of the Asan Medical Center.

Randomized Controlled Trial Multicenter Study
Tapentadol immediate release versus oxycodone immediate release for treatment of acute low back pain.
Tapentadol has demonstrated analgesic efficacy across a range of pain conditions. ⋯ NCT00986180.

Randomized Controlled Trial
Percutaneous epidural lysis of adhesions in chronic lumbar radicular pain: a randomized, double-blind, placebo-controlled trial.
Chronic radicular pain can occur after disc pathology and failed back surgery. An evidence-based effective therapeutic option is not available nor does a gold standard exist. ⋯ Based on the findings of our study as well as other studies, we believe the minimally invasive percutaneous adhesiolysis procedure should be the first choice treatment option for patients with chronic lumbosacral radicular pain who present with clinical history and findings similar to those of the patients enrolled in our study.

Randomized Controlled Trial
Transforaminal hypertonic saline for the treatment of lumbar lateral canal stenosis: a double-blinded, randomized, active-control trial.
Degenerative lumbar spinal stenosis is one of the most common causes of chronic lower back pain and radiculopathy. Spinal stenosis is anatomically classified as central and lateral spinal canal stenosis. Many treatment modalities and techniques, including surgery and epidural injection, have been used to manage the pain. However, the effect of hypertonic saline injection via the transforaminal approach has not yet been studied. ⋯ Superior short-term pain relieving efficacy, but limited long-term effects of hypertonic saline, when added to TFEIs.

Randomized Controlled Trial
Pupillometry: the influence of gender and anxiety on the pain response.
Studies suggest that the pain response may be evaluated using pupillometry and is influenced by factors such as gender and anxiety. ⋯ The pupil dilation in response to a painful stimulus was similar in both genders. Additionally, regardless of gender, the average pupil diameter was greater in the presence of moderate to severe anxiety.
