Huijausvertailija: Pregabalin, Sham tDCS
Patients will receive pregabalin 150 mg oral (PO) twice per day (BID), and sham transcranial direct current stimulation (sham tDCS) five times per week during 2 weeks, and then twice per week until week 8th.
The sham tDCS consists of the same montage of the active tDCS, but the device is turned off 30 seconds after initiating stimulation (without letting the patient notice it).
Rest of the montage is kept identical as the active one during the 30 minutes that the session lasts.

Kokeellinen: Pregabalin, tDCS
Patients will receive pregabalin 150 mg oral(PO) twice per day (BID), and transcranial direct current stimulation (tDCS) five times per week during 2 weeks, and then twice per week until week 8th.
The tDCS consists of application of low intensity direct current (2 mA), with the anode placed in the dominant motor cortex (M1) and the cathode in the ipsilateral supraorbital region during 30 minutes each session, using sponge electrodes soaked with normal saline solution.
