Deep TMS for the Treatment of Patients With Parkinson's Disease and Progressive Supranuclear Palsy

"The Brainsway DTMS produces a time-varying magnetic field and, based on Faraday's Law, it can be assumed that a time-varying magnetic field generates an electrical current in a nearby conductive substance. The induced electric current in the cortex travels in an orthogonal path in the direction of the magnetic field with the maximum strength and current located beneath the coil in the helmet placed on the patient's head and transmits magnetic pulses to the patient's brain. The induced current is tangential to the scalp at the cortical surface, and decreases in magnitude with increasing depth.~Patients underwent 12 sessions, 3 times a week, of repetitive DTMS using the novel H2-coil (Brainsway LDT)."

The Sham DTMS consisted in the same protocol of active treatment with the same preparation of the subject and settings of the instrument but with an INACTIVE DTMS coil.
