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.

Randomized Controlled TrialUltrasound-determined landmarks decreases pressure pain at epidural insertion site in immediate postpartum period.
Women have blamed epidurals for their post-partum back pain for decades. Survey-based studies have shown similar incidence of chronic back pain between women who delivered with epidurals compared to those who did not. However, epidural insertion site pain has yet to be evaluated by a quantitative measure: pressure pain threshold (PPT). Algometer measured PPT has been shown to be accurate and reproducible in acute, chronic, and postoperative pain studies. This study determines the effect of ultrasound-based landmarks on the PPT at the epidural insertion site in the post-partum period. ⋯ We showed that epidural placed with ultrasound-determined landmarks not only improves the success of epidural placement but also minimizes the number of intervertebral levels with decreased PPT.

Comparative StudyAge-related differences in the response of the L5-S1 intervertebral disc to spinal traction.
Lumbar traction is a common treatment for low back pain; however its mechanisms of action are poorly understood. It has been hypothesized that a key effect of lumbar traction is its capacity to influence fluid movement within the intervertebral disc (IVD). ⋯ 4.
