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.

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.

Randomized Controlled Trial
The effectiveness of an Acceptance and Commitment Therapy self-help intervention for chronic pain.
To evaluate the effectiveness of an Acceptance Commitment Therapy based self-help book for people with chronic pain. ⋯ These findings support the hypothesis that using the self-help book, with minimal therapist contact adds value to the lives of people who experience chronic pain.

To examine how the Adult Responses to Children's Symptoms (ARCS) does in a sample of children and adolescents with a variety of complex chronic pain conditions and to further validate the ARCS by examining associations among the subscale scores and patients' functional disability and depressive symptoms. ⋯ This study provides the first-known examination of the factor structure of the ARCS in a large sample of pediatric patients with diverse chronic pain conditions. Confirmatory factor analyses indicate that the ARCS is a valid measure for use with children and adolescents presenting to outpatient pain clinics with a variety of chronic pain complaints.

Clinical Trial
Prospective clinical study of a new implantable peripheral nerve stimulation device to treat chronic pain.
To evaluate clinical use of the StimRouter, an investigational implanted peripheral nerve stimulator for treating chronic neuropathic pain, using the median nerve as a model for that general application. ⋯ Temporary implant of the StimRouter device resulted in both pain reduction and reduced use of oral opioid pain medication during the 5-day stimulation period. The results suggest that permanent implant of the StimRouter System may be safe and effective for treating chronic peripheral neuropathic pain.
