Temporal summation (TS) of pain protocols typically involve the delivery of brief repetitive noxious stimuli held at a constant intensity and measuring the consequent increase in the perceived intensity of pain sensations. To date, no studies have examined the effect of a TS protocol on the perceived spatial dimensions of the pain experience and its interaction with age. This study used a new T...

Background: In the “treating to target” strategy to rheumatoid arthritis (RA) management, “cognitive” beyond “physical” measures allow a more comprehensive assessment. This study reports a predictive analysis of patient properties on Disease Activity, and the degree to which these predictions could be uniquely attributable to Illness perception (IP), pain, and sex differences. Methods: This cr...

OBJECTIVE We assessed whether quality of life (QoL) improvement in duloxetine-treated patients with diabetic peripheral neuropathic pain (DPNP) correlates with the extent of pain relief. METHODS Pooled data from three multicountry, double-blind, 12-week, placebo-controlled trials of duloxetine-treated (duloxetine 60 mg once daily; total number =335) patients with DPNP were analyzed. Based on ...

BACKGROUND Lumbar pathologies may cause the perception of leg pain, but the character of this pain has not been described. Diagnosis is often based on dermatomal charts, but observations reveal that the pain is not typically perceived on the skin. OBJECTIVE To document the incidence of superficial versus deep pain localization among patients with lumbar radicular pain. METHODS Twenty-five p...

SETTING Nine midwifery practices in different regions of the Netherlands. POPULATION A cohort of 223 low-risk pregnant women in the Netherlands was followed from week 12 of gestation until 36 w...

We examined whether pain outcomes (pain interference, perceived pain treatment effectiveness) vary by race and then whether opioid use moderates these associations. These analyses are part of a retrospective cohort study among 3,505 black and 46,203 non-Hispanic, white Department of Veterans Affairs (VA) patients with diagnoses of chronic musculoskeletal pain who responded to the 2007 VA Survey...
