Music has been shown to modulate pain, although the impact of music on specific aspects of nociceptive processing is less well understood. Using quantitative sensory testing (QST), we assessed the impact of a novel music app on specific aspects of nociceptive processing. ⋯ Several measures of mechanical pain sensitivity were reduced with music. TSP, a measure of central sensitization, also decreased with music, but CPM, a measure of descending modulation of pain, was not further augmented by music.

To estimate the effects of excess body mass and leisure time physical activity on the incidence and persistence of chronic pain. ⋯ Obesity not only increases the risk of developing chronic pain, but also increases the risk of persistent pain, while leisure time physical activity reduces the risk of developing chronic pain.

Randomized Controlled Trial
Feasibility and Acceptability of an Abbreviated, Four-Week Mindfulness Program for Chronic Pain Management.
The Mindfulness-Based Stress Reduction program is effective at improving chronic pain outcomes, but the time demand hinders participation. This preliminary study evaluated the feasibility, acceptability, and potential effects of providing an abbreviated mindfulness program for patients with chronic pain. ⋯ In adults with chronic pain, a four-week mindfulness program is feasible and acceptable, addresses the barrier of a lengthy program, and may improve quality of life and psychological functioning. An appropriately powered randomized controlled trial with a comparison group is needed to assess the intervention's effectiveness.

To determine the autonomic effects of suboccipital release (SOR) during experimentally induced pain, 16 healthy subjects (eight women, eight men) experienced ischemic (forearm postexercise muscle ischemia [PEMI]) and cold (cold pressor test [CPT]) pain. ⋯ SOR has the capacity to modulate pain-induced autonomic control and regulation.

The literature on cervical provocation discography (C-PD) is sparse. A "Startle Response" during C-PD is a known phenomenon that might be mistaken as an indicator of discogenic pain at the provoked disc level, but this has not been quantitatively described. ⋯ The present data demonstrate high discordance, 45% (95% CI = 24-68%), between the Startle Response and true-positive C-PD. Clinicians should be aware of this phenomenon and take care to distinguish it from a true-positive response during C-PD, as defined by the SIS guidelines. Misinterpretation of the Startle Response as a positive C-PD result may lead to inappropriate future care decisions in a substantial proportion of patients.
