Meanwhile, Sham-Active group will carry out the opposite protocol, participants will start an allocated 5 sessions (1 per week) of sham acupuncture combined with HRV evaluation, and after a 1-week washout period will be reallocated to 5 sessions (1 per week) of active acupuncture combined with HRV evaluation.
