The Effect of Multi-session Transcranial Direct Current Stimulation Applied Over the Primary Motor Cortex on Motor Sequence Learning in Parkinson's Disease

The present study seeks to examine the efficacy of multi-session transcranial direct current stimulation applied over the primary motor cortex in people with Parkinson's disease on sequential motor learning performance.

Szczegółowy opis

Parkinson's disease is characterised by deficits of motor control triggered by impaired basal ganglia function, such as bradykinesia and tremor. Beyond the visibly recognisable motor symptoms of Parkinson's disease, the ability to learn a sequence of movements is also compromised and poses a significant barrier to effective rehabilitation. In healthy individuals, transcranial direct current stimulation applied over the primary motor cortex during motor task practice has been shown to significantly improve motor learning compared to placebo conditions.

The present study seeks to examine the effect of multi-session transcranial direct current stimulation applied over the primary motor cortex in people with Parkinson's disease on sequential motor learning performance. Participants will be required to attend eight laboratory sessions, comprising five intervention and three assessment sessions and will be tested on their ability to learn a 16-digit finger tapping sequence with their right hand. Sessions one to five will form the intervention and will be performed at the same time on consecutive days (i.e. mon-fri). In addition, session one will double as a baseline assessment and intervention session. Assessments sessions will be performed once before the intervention (session one), and three times following the intervention on day three, one week, and four weeks post intervention.

Pozorny komparator: Sham tDCS
Anodal electrode (35 cm2 sponge electrode) placed over C3. Cathodal electrode (35 cm2 sponge electrode) placed over the right supraorbital area. Stimulation was phased in for 30 seconds up to 2 mA and then switched off. Stimulation was again phased in for 30 seconds following 20 minutes of no stimulation.

Transcranial electrical stimulation device. A weak direct electrical current, up to 2 mA, is passed between two electrodes placed on the scalp. Electrodes are housed in 35 cm2 sponges saturated with 4 ml of saline solution (0.9 % NaCl) per side, per pad.

Stimulation is phased in with a 30-second ramp up of the electrical current to the specified stimulation parameters. Following the specified stimulation period, the current is phased-out with a ramp down of the current. For sham stimulation, the ramp-up and ramp-down periods are retained, but stimulation is switched off during the specified stimulation period.
