The Efficacy and Mechanism of SMA+M1 Repetitive Transcranial Magnetic Stimulation on Freezing of Gait in PD

"The M1 stimulation session consisted 40 trains of 10-Hz rTMS with the protocol of 5s train session and 25s intertrain intervals. There were 4000 pulses per day for M1-LL (unilateral stimulation 2000 pulses). For SMA stimulation, a 5s burst of 10Hz rTMS was repeated 20 times (1000 pulse, 20 minutes' duration).~Patients in the Experimental group underwent ten sessions of double-site high frequency rTMS over the bilateral primary motor cortex (M1) of the lower leg and supplementary motor area (SMA)."

There were 4000 pulses per day for M1-LL (unilateral stimulation 2000 pulses). Patients in the Active Comparator group underwent ten sessions of single-site active magnetic stimulation with high frequency rTMS over the bilateral M1 of the lower leg.

Patients in the Sham Comparator group underwent 10 sessions of double sham rTMS on M1 of the lower leg.
