“…The system can measure conductance values in the range 1-200 μS, with a noise level below 0.002 μS. The measuring unit also has error detection that provides a warning for events caused by a loose electrode and external interference (8)(9)(10). The threshold for SCR recordings in this study was 0.02 μS.…”

“…The SCM is a device that can measure changes in skin conductance in real-time to assess sympathetic activity in There is no other diagnosis that better explains the signs and symptoms CRPS: complex regional pain syndrome the limbs (Med-Storm Innovation version 2005, MedStorm, Oslo, Norway). Measurements can be obtained by use of three self-adhesive non-invasive electrodes denoted C (Current), R (Reference), and M (Measurement), and these electrodes can be attached to the palmar or plantar side of the skin (8)(9)(10). The definition of a skin conductance response is the sequence of the minimum followed by a maximum in conductance values in micro siemens (μS).…”

Aim: Sympathetic system dysfunction has been described among the theories involved in the pathophysiology of complex regional pain syndrome. Objective measurement of the sympathetic activity of the affected extremity in patients with complex regional pain syndrome has not been compared to normal subjects in the literature. The skin conductance monitor is a non-invasive monitor that can objectively measure sympathetic skin activity of the extremity. In this study, we aimed to compare the differences in sympathetic activity of extremities in subjects with and without complex regional pain syndrome by using a skin conductance monitor. Material and Methods: Sympathetic skin responses were evaluated in 63 subjects, including 25 measurements on the affected extremities in 13 patients with lower extremity complex regional pain syndrome type 1 and 50 measurements in 50 normal subjects in the control group. Among the skin conductance indices, the "peaks per second (0.02)" index was used as the main sympathetic skin response index. Descriptive criteria and the mean values of sympathetic skin response measurements were compared. Results: When sympathetic skin responses were compared with a skin conductance monitor using the "peaks per second (0.02)" index, no statistically significant difference was found between the complex regional pain syndrome and control groups in terms of sympathetic activity in the extremities (p=0.837). Conclusion:In this study, skin sympathetic nerve activity in the affected limb of patients with complex regional pain syndrome was similar to normal subjects. Further studies are required to assess the changes in sympathetic activity in complex regional pain syndrome.

“…When the SNS is activated, the palmar sweat glands fill, causing reduction in skin resistance and increase in SC. 22 This change in electrical characteristics of the skin is measured by electrodes and reflects the countercurrent electrical conductance associated with physiological arousal. 23 Unlike other physiological measures, such as heart rate, SC is not influenced by hemodynamic changes, making it an effective measure of stress reactivity.…”

Fathers' Heightened Stress Responses to Recounting their NICU Experiences Months after Discharge: A Mixed Methods Pilot Study

et al. 2021

Objective The acute and traumatic events associated with having a newborn who requires admission to the neonatal intensive care unit (NICU) may elicit long-term concerns for parents postdischarge. Cognitive processing of taxing events influences recurring stress responses, which can be inferred via biomarkers such as salivary cortisol (sCort) and skin conductance (SC). In addition, personal narratives provide an important insight into individual perceptions and coping strategies. The current pilot study aimed to (1) test the hypotheses that fathers' sCort and SC would peak in response to stress induction and decrease during recovery, (2) examine associations among stress biomarkers and stress perceptions, (3) explore fathers' narratives using thematic analysis, and (4) integrate fathers' narrative themes with their stress responsivity. Study Design Using a convergent mixed methods approach, we enrolled 10 fathers of infants formerly cared for in NICU who underwent a Trier Social Stress Test including recounting their NICU experience months postdischarge. Stress responsivity was measured via sCort and SC, while stress perceptions were identified by using the Perceived Stress Scale and Distress Thermometer-Parent. Personal narratives were explored by using thematic analysis. Results The significant rise in fathers' sCort and SC in response to stress induction was reflected in narrative themes including loss, worry, and role strain. Subsequently, fathers' sCort and SC returned to baseline, which was illustrated by themes such as role strength, coping, and medical staff interactions. Fathers' stress measured by PSS was lower than that required for mental health referral, and did not correlate with stress biomarkers. Conclusion Salivary cortisol and skin conductance are useful biomarkers of paternal stress responsivity and recovery. Thematic analysis identified fathers' NICU stressors and coping strategies that mirrored their stress responsivity patterns. Further studies are needed to more broadly examine the sociodemographic variables that influence stress reactivity and perceptions in parents of infants formerly cared for in NICU. Key Points
