Efficacy of Deep-coil Based Repetitive Transcranial Magnetic Stimulation in the Treatment of Parkinson's Disease With Freezing of Gait and Its Neural Regulation Mechanism Study of Resting-state Cerebral Blood Flow

rTMS is a non-invasive brain stimulation technique that stimulates specific brain areas through repeated magnetic pulses to treat depression, anxiety and other mental illnesses, and to study brain function.

participants receive Non-stimulation:The side of the double cone coil is placed against the scalp, and the target of the coil is stimulated in the direction of air.
