Randomized Controlled Trial
A preliminary report of a randomized double-blind, active controlled trial of fluoroscopic thoracic interlaminar epidural injections in managing chronic thoracic pain.
The proportion of patients suffering from thoracic pain secondary to thoracic disorders is relatively small compared to low back and neck pain. Furthermore, thoracic interventions are not performed as often as in cervical and lumbar regions. In addition, there is a paucity of literature regarding thoracic intervertebral discs and thoracic disc herniation as causative structures of thoracic pain. ⋯ NCT01071369.

Randomized Controlled Trial
Management of pain of post lumbar surgery syndrome: one-year results of a randomized, double-blind, active controlled trial of fluoroscopic caudal epidural injections.
Post lumbar surgery syndrome represents a cluster of nomenclature and syndromes following spine surgery wherein the expectations of the patient and spine surgeon are not met, with persistent pain following lumbar surgery. Multiple causes have been speculated to cause pain after lumbar surgery. Epidural steroid injections are most commonly used in managing post surgical pain in the lumbar spine. However, there is a paucity of evidence of epidural injections in managing chronic low back pain with or without lower extremity pain in post surgery syndrome. ⋯ NCT00370799.

Randomized Controlled Trial
Comparative outcomes of a 2-year follow-up of cervical medial branch blocks in management of chronic neck pain: a randomized, double-blind controlled trial.
Cervical therapeutic intraarticular facet joint injections, therapeutic medial branch blocks, and radiofrequency neurotomy have been applied in managing chronic neck pain of cervical facet joint origin. However, the effectiveness of these modalities continues to be debated. The purpose of this study was to determine the clinical effectiveness of therapeutic cervical medial branch blocks with or without steroids. ⋯ NCT00332722.

Randomized Controlled Trial
Preliminary results of a randomized, double-blind, controlled trial of fluoroscopic lumbar interlaminar epidural injections in managing chronic lumbar discogenic pain without disc herniation or radiculitis.
Low back pain without disc herniation is the most common problem among chronic pain disorders. Epidural injections are commonly used interventions in managing chronic low back pain without disc herniation. However, little evidence exists regarding the effectiveness, indications, and medical necessity of lumbar epidural injections in managing axial low back pain without disc herniation or radiculitis. ⋯ Lumbar interlaminar epidural injections of local anesthetic with or without steroids was effective in 63% and 74% of patients with chronic function-limiting low back pain without facet joint pain, disc herniation, and/or radiculitis.

Randomized Controlled Trial
Pulse width programming in spinal cord stimulation: a clinical study.
With advances in spinal cord stimulation (SCS) technology, particularly rechargeable implantable, patients are now being offered a wider range of parameters to treat their pain. In particular, pulse width (PW) programming ranges of rechargeable implantable pulse generators now match that of radiofrequency systems (with programmability up to 1000 microseconds. The intent of the present study was to investigate the effects of varying PW in SCS. ⋯ Variable PW programming in SCS appears to have clinical value, demonstrated by some patients improving their paresthesia-pain overlap, as well as the ability to increase and even 'steer' paresthesia coverage.
