Defective Endogenous Pain Modulation in Fibromyalgia: A Meta-Analysis of Temporal Summation and Conditioned Pain Modulation Paradigms.
To study the characteristics of temporal summation (TS) and conditioned pain modulation (CPM) in fibromyalgia (FM) patients, we systematically searched Pubmed and EMBASE for studies using TS or CPM comparing FM patients with healthy controls. We computed Hedges' g, risk of bias, sensitivity analysis, and meta-regression tests with 10,000 Monte-Carlo permutations. Twenty-three studies (625 female and 23 male FM patients and 591 female and 81 male healthy controls) were included. ⋯ Although studies were of low risk of bias, lack of blinding was substantial. Sensitivity analysis and meta-regression identified type and site of stimulation, age, lab, sample size, and medication control as important sources of between-study variability. We showed a significant alteration of pain modulation mechanisms in FM patients.

This study provides prevalence estimates of plantar fasciitis in U. S. adults, as well as the types and frequencies of pharmaceutical treatment specifically for this pain. Data are from the 2013 National Health and Wellness Survey, a large (n = 75,000) internet panel survey designed to approximate the adult U. S.
