Transcranial Direct Current Stimulation Combined With Transcranial Magnetic Stimulation for Motor and Non-Motor Symptoms of Parkinsonian Syndromes

Bilateral pre-treatment with tDCS is carried out for 10 minutes. The current is 2 mA, and the electrodes are spaced 5 cm apart. The current gradually rises and falls in the first and last 30 seconds. Subsequently, the bilateral primary motor cortex (M1 area) of the patient is stimulated with iTBS at a frequency of 5 Hz. The magnetic field intensity is set at 80% of the resting motor threshold. Each train contains 10 pulses, and each pulse consists of 3 bidirectional pulses at 50 Hz. The interval between each train is 8 seconds. There are 60 trains per session (1800 pulses per session), and the treatment lasts for 5 days in total.

Participants received sham transcranial direct current stimulation combined with intermittent theta burst stimulation for a total of 5 days
