“…This is in accordance with Martin et al [50] findings, where he defended the theory that the improvement of pain is one of the factors that results in the improvement of the quality of life. The use of HRV analysis has been increasingly used to better understand the behavior of the ANS in various diseases, as seen in the study by Marães [51]. Changes in HRV standards provide a sensitive and early indicator of health impairments.…”

Background: Fibromyalgia is a syndrome of chronic, generalized muscular pain, accompanied by sleep disturbances, fatigue and cardic autonomic dysfunction that will affect the quality of life. There is currently no gold standard treatment. There are limitations of studies with electroacupuncture in auricular acupuncture. Objectives: We evaluate the effects of systemic electroacupuncture (EA) with frequencies of 2/100 Hz associated of auricular acupuncture with a Nogier frequency (2.28, 4.56 and 9.12 Hz) for pain intensity, heart rate variability (HRV), and quality of life in fibromyalgia. Methods: Randomized clinical trial, a pilot study. Eighteen volunteers were randomized into a control group (CG, n = 9) and an experimental group (EG, n = 9). Six systemic EA sessions systemic and auricular were applied in the EG for 20 min, twice a week, for six weeks consecutive. The Numerical Pain Assessment Scale (NPRS), 2010 diagnostic criteria of the American College of Rheumatology (FDC 2010), Fibromyalgia Impact Questionnaire (FIQ) and analysis of HRV were the instruments used. The independent t-test compared to the groups was applied. Results: There was no statistically significant difference for the primary outcome for NPRS (p > 0.05). In the secondary outcome there was a significant difference in the total score and in some FIQ domains (p = 0.008) and some variables such as pain (p = 0.02) and anxiety (p = 0.006). There was no significant difference for the FDC 2010 and HRV variables (p > 0.05). Conclusion: 2/100 Hz systemic EA associated with the Nogier frequency positively influenced some quality of life variables; however, pain intensity, diagnostic criteria, and HRV variables did not change.

“…In the time domain, the RMSSD, pNN50, and SDNN indices will be used. The RMSSD is the square root of the mean of squared differences between successive beat intervals 64,65 ; the pNN50 index, in turn, is a sensitive and easily interpretable marker of the parasympathetic ANS modulation, defined as the percentage of successive differences in the R-R intervals whose absolute value exceeds 50ms; and the SDNN reflects the participation of both branches of the ANS and corresponds to the standard-deviation of the mean of all normal RR intervals, expressed in ms [66][67][68][69] .…”

Backgroung: the growing of patients with multiple sclerosis seeking acupuncture treatment is based on clinical reports of improvements in symptoms. Considering that autonomic impairment, including cardiovascular autonomic dysfunction, is not uncommon in patients with MS, neuromodulation with acupuncture could be an interesting tool to change heart rate variability in this population. Objective: to evaluate heart rate variability in patients with multiple sclerosis, during the application of acupuncture, in order to analyze the behavior of the autonomic nervous system before, during and after therapy and changes in condition after a longitudinal intervention. Methods: a double-blinded randomized sham-controlled crossover trial with a 1:1 allocation ratio will be conducted, with 40 individuals without a previous illness, who will constitute the control group, and 40 individuals with Multiple Sclerosis, who will constitute the experimental group, paired by age and sex. All participants will undertake active or sham acupuncture sessions. Discussion: according to the studies found, cardiovascular autonomic dysfunction is expected, with alterations in heart rate variability. Although neuromodulation with acupuncture can control pain and inflammation, there are still difficulties in affirming whether the balance between the sympathetic and parasympathetic systems can be changed by acupuncture. Trial registration: We registered this trial on ClinicalTrials.gov, ID: NCT05523466
