Lumbar flexion-relaxation is a well-known phenomenon that can reliably be seen in normal participants, but not in most chronic low back pain (CLBP) participants. No earlier studies have investigated any specific clinical intervention designed to correct abnormal flexion-relaxation. The objective of this study was to evaluate the contribution of a surface EMG-assisted stretching (SEMGAS) biofeedback training protocol, within a functional restoration treatment program, on flexion range of motion (ROM) and erector spinae surface EMG (SEMG) during maximum voluntary flexion (MVF). ⋯ Interdisciplinary functional restoration rehabilitation of CLBP participants is effective for increasing ROM and other functional measures, but the addition of a SEMGAS biofeedback training protocol can result in normalization of the flexion-relaxation phenomenon, so that these participants are comparable with a pain-free control group.

Opioids are indicated for the management of procedural pain in neonates. There are limited data describing factors influencing patterns of use. ⋯ Neonatologists frequently report using opioids to manage procedural pain, however, spontaneously breathing infants are less likely to receive them, and their use varies according to infant and procedure characteristics. These data point to the need to further investigate, in a more controlled design, the pharmacologic effects of opioids in this population to better guide clinicians about their optimal use.

Randomized Controlled Trial Comparative Study Clinical Trial
Intra-articular corticosteroid injections versus pulsed radiofrequency in painful shoulder: a prospective, randomized, single-blinded study.
Chronic shoulder pain treatment is known to be a difficult and long process. The objective of this study is to compare the efficacy of intra-articular corticosteroid injection and pulse radiofrequency (PRF) applied to the suprascapular nerve in patients with shoulder pain. ⋯ Intra-articular injection of corticosteroid and PRF applied to the suprascapular nerve are effective in the treatment of painful shoulder. When 2 treatments are compared, it may be concluded that intra-articular steroid injection was more effective especially in the first weeks regarding pain than the PRF. Further studies are needed to confirm these results in the prospective treatment guidelines.

Randomized Controlled Trial
Transcutaneous pulsed radiofrequency treatment in patients with painful knee awaiting total knee joint replacement.
Our study was designed to determine if transcutaneous-pulsed radiofrequency treatment (TCPRFT) was able to reduce the pain experienced by patients awaiting total knee joint replacement (TKJR). We conducted a randomized, double-blinded, placebo controlled trial of TCPRFT in patients referred for TKJR to our hospital's Orthopedic Outpatient Clinic. ⋯ We believe this to be the first report of a controlled study of TCPRFT. This pilot study shows a benefit of the technique that justifies future research.

In current medical literature, most of the reported complications of spinal cord stimulation concern technical problems, such as lead malfunction, migration, breakage, or internal pulse generator dysfunction, whereas reports about the side effects on internal organ function caused by spinal cord stimulation are rare. ⋯ This case report highlights the incomplete knowledge about the mechanism of action of spinal cord stimulation and its influence on the interactions between the autonomic nervous system and voluntary control of urinary function. The complete recovery of bladder function after the interruption of stimulation suggests that electrical stimulation caused the adverse effects in this clinical case.
