Background and Objective: Heart rate variability (HRV) as an index of the autonomic
nervous system appears to be related to reactivity to experimental pain stimuli. HRV could …

Both sympathetic and parasympathetic nervous systems are involved in regulating pain
states. The activity of these systems seems to become disturbed in states of chronic pain …

This study systematically reviewed differences in pain perception between athletes and
normally active controls. We screened MEDLINE, Sport-Discus, EMBASE, Web of Science …

Background Reactivity of the autonomic nervous system to experimental pain stimuli has
been extensively studied using measures of heart rate and blood pressure. Heart rate …

Breathing techniques are commonly used to alleviate pain. Despite their frequent use,
surprisingly little is known about their efficacy as well as their underlying physiological …

Previous studies have reported that 15% to 25% of patients treated for breast cancer
experience long-term moderate-to-severe pain in the area of surgery, potentially lasting for …

Abstract Study Objectives: We characterized sleep disorder rates in temporomandibular joint
disorder (TMD) and evaluated possible associations between sleep disorders and …

The study investigated relationships between autonomic cardiovascular control and
attentional performance. In 60 healthy subjects R-wave to pulse interval (RPI), respiratory …

Objective The goal of this systematic literature review is to determine whether there are
differences and similarities in heart rate variability (HRV) between adult patients with …

Between-person variability in pain sensitivity remains poorly understood. Given a
conceptualization of pain as a homeostatic emotion, we hypothesized inverse associations …
