Blood pressure-related pain modulation in fibromyalgia: Differentiating between static versus dynamic pain indicators

Abstract

Introduction Resting blood pressure (BP) has been found to be inversely associated with evoked pain responsiveness in healthy populations. However, some reports suggest that BP-related pain modulation may be dysfunctional in chronic pain patients. This study examined whether BP-related pain modulation, indexed by both static and dynamic evoked pain responses, is altered in fibromyalgia (FM) patients compared to pain-free individuals.Method Pain threshold and tolerance as static evoked pain measures and slowly repeated evoked pain (SREP) as a dynamic evoked pain index were measured in 30 FM patients and 27 healthy controls. BP was continuously recorded throughout a 5 minute pre-pain rest period.Results SREP sensitization was observed only in the FM group. Higher BP predicted elevated pain threshold and tolerance in healthy individuals, but not in FM. Conversely, BP was inversely associated with SREP sensitization in FM whereas no association was found in healthy controls.Conclusions Static evoked pain measures suggested BP-related pain inhibitory dysfunction in FM. In contrast, for pain sensitization as indexed by SREP, FM displayed the expected BP-related inhibitory effects. BP-related pain modulation is manifested in FM differentially for static versus dynamic pain indicators. Use of both types of evoked pain measures may be valuable in the study of mechanisms underlying altered pain modulatory systems in FM.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The pathophysiology of fibromyalgia syndrome seems to be related to sensitization of central nervous system processes, which underlie alterations in pain perception, deficient pain inhibition, temporal summation of pain, and other indicators of pain sensitization.

    “Regarding the etiopathophysiology of FMS, while its etiology remains unknown, the pathophysiology of this chronic condition seems to be related to the sensitization of CNS processes, e.g., [5,22,23], which underlie the alterations in pain perception displayed by these patients, (e.g., allodynia and hyperalgesia) [24], deficient pain inhibition [25], temporal summation of pain [26] and other”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
