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
