Randomized Controlled Trial Comparative Study
Exercise- and Stress-Induced Hypoalgesia in Musicians with and without Shoulder Pain: A Randomized Controlled Crossover Study.
Professional and pre-professional musicians are characterized by physical and psychological demands inherent to their musical activity, and therefore at risk for developing performance related musculoskeletal pain. Physical and psychological demands are known to influence human pain modulation. ⋯ In musicians with and without regional shoulder pain, no significant differences were found with respect to pain modulation during a physically and an emotionally stressful task. Both interventions adequately activated central and widespread pain inhibitory mechanisms in both groups.

Randomized Controlled Trial Multicenter Study
MiDAS ENCORE: Randomized Controlled Clinical Trial Report of 6-Month Results.
Patients suffering from neurogenic claudication due to lumbar spinal stenosis (LSS) often experience moderate to severe pain and significant functional disability. Neurogenic claudication results from progressive degenerative changes in the spine, and most often affects the elderly. Both the MILD® procedure and epidural steroid injections (ESIs) offer interventional pain treatment options for LSS patients experiencing neurogenic claudication refractory to more conservative therapies. MILD provides an alternative to ESIs via minimally invasive lumbar decompression. ⋯ NCT02093520.

Pulsed radiofrequency (PRF) is a novel nondestructive interventional technique for the treatment of neuropathic pain (NP). However, this intervention is still lack of relevant regulation and the mechanism of action is insofar not clear. Historically, most studies have reported that PRF can relieve reduce hyperalgesia in multiple NP animal models by acting on the dorsal root ganglion. However, a few recent studies have shown that PRF can effectively treat hyperalgesia in pain models by a direct application on injured peripheral nerves. ⋯ The findings suggest that the application of PRF at the impaired SN relieved reduced the CCI-induced NP by through regulating the upregulation of the GDNF expression in the nervous tissues.

Percutaneous transforaminal techniques for the treatment of lumbar disc herniation have markedly evolved. Percutaneous endoscopic lumbar discectomy (PELD) for L5-S1 disc herniation is regarded as challenging due to the unique anatomy of the iliac crest, large facet joint, and inclinatory disc space. Among these, the iliac crest is considered a major obstacle. There are no studies regarding the height of the iliac crest and their appropriate procedures in PELD. ⋯ In high iliac crest cases where the iliac crest is above the mid L5 pedicle in lateral radiography, foraminoplasty may be considered for transforaminal access of L5-S1 disc herniation. Conventional transforaminal access can be utilized with ease in low iliac crest cases where the iliac crest is below the mid-L5 pedicle.

Percutaneous endoscopic interlaminar discectomy (PEID), which poses advantages for certain types of herniated disc, is gaining wider acceptance in clinical practice. We retrospectively analyzed the efficacy of the PEID technique in treatment of calcified lumbar disc herniation. ⋯ The PEID technique is an effective method in the treatment of calcified lumber disc herniation, although the rate of postoperative dysesthesia is higher in this group during the early postoperative period. Long-term TCM administration may be related to the calcification of herniated lumbar discs.
