“…For example, FMS patients showed higher SC reactivity to emotional and mental stress than healthy individuals, with no differences seen at baseline [ 8 , 9 , 22 , 23 ]. This greater SC reactivity contrasts with findings observed in other chronic pain conditions (e.g., chronic low back pain), in which lower SC reactivity was observed [ 24 ]. Regarding peripheral blood flow, decreased microcirculatory blood flow (indicating greater vasoconstriction) has been observed in tender points of FMS patients [ 25 ].…”

Alterations in autonomic activity are well established in fibromyalgia syndrome (FMS). Previous studies found reduced parasympathetic activity and sympathetic reactivity to physical and stress manipulations. However, sympathetic activity at rest has not been well studied in FMS. Sweating is exclusively controlled by sympathetic mechanisms. In this study, skin conductance (SC), as an indirect measure of sweating, was analyzed in 45 women with FMS and 38 healthy women. Tonic SC levels were recorded during a 4-minute rest period, and a breathing maneuver consisting of deep breathing with posterior breath holding was used to evoke SC responses. Associations of tonic SC with state anxiety and body temperature, measured in the hand, were explored to determine sweat functionality. The results showed reduced tonic SC levels, with a less marked decrease in SC during the recording period, and blunted SC reactivity to the breathing manipulation in FMS patients relative to healthy participants. Positive associations of SC with state anxiety and body temperature were observed in healthy participants, but these associations were absent in FMS patients. These results indicate alterations of sweating in FMS, suggesting reduced tonic and reactivity sympathetic influences. Furthermore, the absence of associations between SC levels and state anxiety and body temperature in the patient sample suggested a loss of functionality of the autonomic nervous system in FMS. Diminished autonomic regulation in FMS would reduce the ability to cope with environmental demands, thus favoring increases in stress and pain levels. Finally, the observed reduction in sweating is in accordance with evidence of small nerve fiber neuropathy in FMS.

“…Several studies [ 37 , 43 , 55 , 59 , 82 ] failed to find any difference in EDA levels in depressed patients in response to antidepressant treatment or other medication, but it is hard to draw clear conclusions from these studies, many of which assessed non-specified antidepressants and/or antipsychotic medication.…”

“…After the original 1978 study by Myslobodsky and Horesh [ 96 ] others reported that EDA levels were lower on the right hand than the left under various experimental conditions, including rest [ 97 ]. Nevertheless, contrasting results were obtained both at rest and during stimulation [ 65 , 98 ], and during different phases of illness, including remission [ 37 , 99 ]. Notably, the first two studies cited in this paragraph had lower NOS scores (3 and 2) than the last four (respectively 4, 6, 5, 5); the existence of lateral differences in EDA remains to be confirmed.…”

The association between electrodermal activity (EDA), depression and suicidal behaviour: A systematic review and narrative synthesis

et al. 2018

BackgroundElectrodermal activity (EDA) and other peripheral autonomic electrical parameters have been used as indicators of emotional states, including depressive states and suicidal state. We aimed to review EDA research systematically, focusing on EDA’s usefulness as a biomarker for depression and suicidal behaviour.MethodsWe searched MEDLINE, Scopus, Cochrane Library, and Web of Science databases, following PRISMA guidelines. The initial screening of articles was based on titles and abstracts; then the full text was reviewed. A preliminary synthesis of findings was developed using tables, thematic analysis and quality ratings.Results1287 articles were screened and 77 relevant studies were identified and included in the systematic review. The studies were fairly consistent in maintaining that hypoactive electrodermal response is an established feature of patients affected by depression. There is also preliminary evidence that monitoring EDA may help to differentiate the phases of mood disorders. A few studies provided evidence that EDA can be used to differentiate acutely suicidal subjects from depressed patients who are not severely suicidal. Although EDA has been shown to be a valid, sensitive marker of suicidal ideation, suicide attempts and violent suicidal behaviour, it also seems to be influenced to some extent by antidepressant treatment.ConclusionsMost of the studies summarised in this review are quite outdated and employed a variety of designs and methods to evaluate EDA. This limits the generalisability of the results and makes it difficult to draw clear conclusions about the role of EDA in real-world settings. Electrodermal hypoactivity seems to be a reliable feature of depression and a valid marker of suicidal risk. Nevertheless, the potential utility of EDA in diagnosis, prevention, and treatment planning for depression and suicidal behaviour, should be thoroughly studied.

“…Higher SCL in response to stress and during recovery from stress, which indicates enhanced sympathetic response to stress, has previously been found in FMS [ 38 ]. Higher spontaneous electrodermal activity [ 61 ] and enhanced activity in response to pain [ 62 ] and sound stimulation [ 66 ] has also been found in CLBP patients.…”

Physiological responses to low-force work and psychosocial stress in women with chronic trapezius myalgia

Background: Repetitive and stressful work tasks have been linked to the development of pain in the trapezius muscle, although the underlying mechanisms still remain unclear. In earlier studies, it has been hypothesized that chronic muscle pain conditions are associated with imbalance in the autonomic nervous system, predominantly expressed as an increased sympathetic activity. This study investigates whether women with chronic trapezius myalgia show higher muscle activity and increased sympathetic tone at baseline and during repetitive low-force work and psychosocial stress, compared with pain-free controls.
