Study type
Interventional
Description of intervention(s) / exposure
Participants will receive a 30-minute repetitive transcranial magnetic stimulation (rTMS) treatment each week day for four weeks (20 treatments in total).

rTMS will be delivered with a Medtronic Magpro stimulator at 1 Hz and 120% of motor threshold in one continuous train of 30 minutes duration (1800 pulses per day).
Intervention code [1] 287285 0
Treatment: Devices
Comparator / control treatment
The clinical efficacy of rTMS delivered to two different brain areas will be compared:

1. right hemispheric premotor cortex

versus

2. bilateral supplementary motor area

Each participant will receive treatment at one (not both) of these brain sites.
