Does a Healing Procedure Referring to Theta Rhythms Also Generate Theta Rhythms in the Brain?

Background/objectives: ThetaHealing® (Vianna Stibal, Kalispell, MT) is a spiritual healing method in which the practitioner and client engage in joint meditations during several healing sessions. It is claimed that these meditation periods are characterized by a "theta state" in which the presence of theta-waves in the electroencephalograph (EEG) frequency spectrum of both the healer and the client is supposed. This study sought to test this hypothesis as well as the presence of synchronicities in the two EEGs.
