“…Similarly to our study, where there was a stronger group difference in subjective measures (stress levels) than objective measures, Tome-Pires et al found only a trend for higher skin conductance responses for pain descriptors and emotional words in migraine patients compared to controls, but a higher recall of emotional words in the migraine group [ 20 ].…”

BackgroundMigraine is a stress-related disorder, suggesting that there may be sympathetic hyperactivity in migraine patients. However, there are contradictory results concerning general sympathetic activation in migraine patients. To shed more light on the involvement of the autonomic nervous system (ANS) in migraine pathophysiology, we investigated cardiac and cardiovascular reactions during vagal (paced breathing) and sympathetic activation (mental stress test).MethodsHeart rate variability parameters and skin conductance responses were recorded interictally in 22 episodic migraine patients without aura and 25 matched controls during two different test conditions. The paced breathing test consisted of a five-minute baseline, followed by two minutes of paced breathing (6 breathing cycles per minute) and a five-minute recovery phase. The mental stress test consisted of a five-minute baseline, followed by one minute of stress anticipation, three and a half minutes of mental stress and a five-minute recovery phase. Furthermore we measured blood pressure and heart rate once daily over 2 weeks. Subjects rated their individual current stress level and their stress level during paced breathing and during the mental stress test.ResultsThere were no significant differences between migraine patients and controls in any of the heart rate variability parameters in either time domain or frequency domain analysis. However, all parameters showed a non-significant tendency for larger sympathetic activation in migraine patients. Also, no significant differences could be observed in skin conductance responses and average blood pressure. Only heart rates during the 2-week period and stress ratings showed significantly higher values in migraine patients compared to controls.ConclusionsGenerally there were no significant differences between migraine patients and controls concerning the measured autonomic parameters. There was a slight but not significant tendency in the migraine patients to react with less vagal and more sympathetic activation in all these tests, indicating a slightly changed set point of the autonomic system. Heart rate variability and blood pressure in migraine patients should be investigated for longer periods and during more demanding sympathetic activation.

“…37,43,56 No significant difference was found regarding the proportion of pain words recalled (relative to neutral words) between the headache and control groups, although a small to medium effect size was indicated (k = 3, g = 0.438, 95% CI [−0.042, 0.918] P = 0.074). Despite no significant heterogeneity (Q = 4.707, P = 0.095), it is worth noting that 2 of the 3 studies reported significant memory bias towards pain information among those with chronic headaches 43 or chronic migraines, 56 yielding medium and large effect sizes, respectively. On the other hand, the results from the third study 37 produced no significant findings.…”

The aim of this systematic review and meta-analysis was to determine the pattern of cognitive processing biases (ie, attentional, interpretation, and memory bias) towards headache and pain information observed in individuals with frequent or chronic headaches or migraines, compared with individuals without. We identified 11 studies (total N 5 841). Most studies (10 of 11) assessed attentional bias. For reaction time-based attentional bias (k 5 8), significant group differences were observed, with small (500 ms; g 5 0.200) to medium ($ 1000 ms; g 5 0.544) effects. Those with chronic headaches showed an absolute attentional bias towards headache and pain information. In 2 eye-tracking studies, both found significant medium-to-large group differences on initial orientation. Interpretation and memory bias research was also reviewed. A medium-to-large effect was found for interpretation bias (k 5 2; g 5 0.708), whereas the effect for recall memory bias (k 5 3) was not significant. Overall, the findings confirm an attentional bias for headache-related stimuli among people with headache, with some evidence for interpretation bias but equivocal evidence for a memory bias. For attentional biases, eye-tracking studies found evidence for biases in initial orienting. We provide suggestions for how to extend the current research to better understand cognitive biases in chronic headache.

“…Skin conductance has also been used for the evaluation of pain in patients with fibromyalgia [188][189][190], showing a response above the base line [191,192], and also for the evaluation of pain in patients with chronic pain in the back [193][194][195][196][197][198] or with a high risk of chronic back pain [197], for the evaluation of shoulder pain [199], chronic lumbar pain [200], patients with post-trauma stress disorders [201], higher depressive disorder [202], tensional headache [195,203], migraine [204], irritable intestine syndrome [205], or arthritis [196]. The authors of [206] quantified the response to pain in patients with Rett syndrome by measuring skin conductance.…”

Non-oncologic chronic pain is a common high-morbidity impairment worldwide and acknowledged as a condition with significant incidence on quality of life. Pain intensity is largely perceived as a subjective experience, what makes challenging its objective measurement. However, the physiological traces of pain make possible its correlation with vital signs, such as heart rate variability, skin conductance, electromyogram, etc., or health performance metrics derived from daily activity monitoring or facial expressions, which can be acquired with diverse sensor technologies and multisensory approaches. As the assessment and management of pain are essential issues for a wide range of clinical disorders and treatments, this paper reviews different sensor-based approaches applied to the objective evaluation of non-oncological chronic pain. The space of available technologies and resources aimed at pain assessment represent a diversified set of alternatives that can be exploited to address the multidimensional nature of pain.
