Individualized rTMS protocol
High frequency rTMS as usual
Trans-cranial direct current stimulation (tDCS)
The target region will be defined by comparing the rCBF scan of the patient to a control population (n = 80). rCBF will be measured using the QUIPS2 arterial spin labeling sequence on a Siemens 3T Verio. The therapeutic protocol will be design to correct the rCBF anomaly first by defining each point where to deliver the stimulation than the stimulation protocol for each point (180% of active motor threshold, 4-second 10 Hz train duration, with 26-second intertrain interval for a total of 3000 pulses). The whole target will be homogeneously stimulated. The active motor threshold will be assessed. The programmed protocol will be delivered while a figure of eight coil will be positioned by a robotic device (Axilum Robotics). The procedure will be repeated twice a day for 10 days over 2 weeks.
rTMS will be performed as usual using a figure-eight coil: Defining the active motor threshold. For each session positioning the coil 5 cm ahead of the abductor pollicis brevis muscle, stimulating at 180% of active motor threshold (10 Hz, 4-second train duration, and 26-second intertrain interval) for 37.5 minutes (3000 pulses per session), twice a day for 10 days over 2 weeks. Coil and stimulator will remain the same between individualized and "as usual" proceedures.
tDCS will be performed as usual: After controlling for skin healthiness, the anode and the cathode will be respectively placed over F3 and F4. A commercial devices (MagStim), will deliver a constant current of 2 mA through 25 cm2 saline-soaked rubber sponges for 20 min per session. The procedure will be repeated twice a day for 10 days over 2 weeks.
