Effect of Multicolumn Lead Spinal Cord Stimulation on Low Back Pain in Failed Back Surgery Patients: A Three-Year Follow-Up.
Spinal cord stimulation (SCS) remains poorly efficient at reducing back pain in failed back surgery syndrome (FBSS) patients. We aimed at determining whether a new multicolumn lead SCS technique was efficient at durably reducing their leg (LP) and back (BP) pain. ⋯ Multicolumn lead SCS in FBSS patients significantly improve BP, LP, quality of life, and medication consumption for at least 36 months. A classical placebo effect cannot account for long-term improvements of such magnitude.

Randomized Controlled Trial
Learned control over spinal nociception in patients with chronic back pain.
Descending pain inhibition suppresses spinal nociception, reducing nociceptive input to the brain. It is modulated by cognitive and emotional processes. In subjects with chronic pain, it is impaired, possibly contributing to pain persistence. A previously developed feedback method trains subjects to activate their descending inhibition. Participants are trained to use cognitive-emotional strategies to reduce their spinal nociception, as quantified by the nociceptive flexor reflex (RIII reflex), under visual feedback about their RIII reflex size. The aim of the present study was to test whether also subjects with chronic back pain can achieve a modulation of their descending pain inhibition under RIII feedback. ⋯ Subjects with chronic back pain can learn to control their spinal nociception, quantified by the RIII reflex, when they receive feedback about the RIII reflex.
