The Efficacy and Safety of Transcranial Temporal Interference Stimulation (tTIS) Targeting the Right Globus Pallidus Internus (GPi) for Motor Symptoms in Patients With PD

The total stimulation duration was 30 minutes, including a 30-second current ramp-up at the beginning and a 30-second ramp-down at the end.

Sham stimulation had only 30 seconds of current ramping-up and ramping-down at the beginning and end of the stimulation, respectively, to simulate the sensation of actual stimulation.
