Summary

Pharmaceutical and neurosurgical treatments reliably ameliorate the cardinal motor symptoms in PD but, they often yield inconsistent outcomes for speech and voice disorders, with some studies showing exacerbation of pre-treatment deficits. Therefore, it is crucial to develop and optimize novel approaches that could simultaneously improve speech and voice deficits in PD and facilitate existing behavioral interventions. This project will investigate the immediate and short-term effects of multiple sessions of HD-tDCS over the left SMA on speech and voice deficits in PD.

Conditions

  • Parkinson Disease

Interventions

DEVICE

Active transcranial direct current stimulation

HD electrodes (diameter of 1.2 cm) will be placed on the participants' skull using an HD-tDCS cap (Soterix Medical Inc. New York) and based on 5-10 international montage. Active stimulations will be delivered by a 9 MxN Soterix HD-tES device for 20 minutes( 2 mA) per day for 5 days.

DEVICE

Sham transcranial direct current stimulation

HD electrodes (diameter of 1.2 cm) will be placed on the participants' skull using an HD-tDCS cap (Soterix Medical Inc. New York) and based on 5-10 international montage. Sham stimulations will be delivered by a 9 MxN Soterix HD-tES device. In the sham tDCS condition, the current is only on for 30 seconds before it is ramped back down to 0 milliamps (mA), although the electrodes are still worn for 20 minutes.
