Randomisation
Patients who provide informed consent to participate and who fulfil eligibility criteria will be enrolled into the study. Initial visit (visit 1) involves baseline assessments of neurocardiovascular, cognitive, and inflammatory status. Participants are then randomised to either active or sham stimulation condition at the following visit and then to the alternate condition at the final visit. Participants are blinded to the active or sham stimulation condition but study researchers are not (i.e. single-blinded). Please see Fig.
