Background: Stimulatory cerebellar TMS is a promising tool to improve motor control in neurodegenerative disorders. Objective/hypothesis: Our goal was to use 10Hz cerebellar rTMS to augment cerebellar-brain inhibition (CBI) for improved postural stability and speech in patients with progressive supranuclear palsy (PSP). Methods: We performed CBI assessments with neuronavigation before and after high frequency cerebellar rTMS or sham TMS in two patients with PSP, using a double cone coil for the conditioning pulse and a figure-of-eight coil for the test pulse and treatments. We collected posturography data and speech samples before and after treatment. Results: After treatment, CBI increased by 50% in subject 1 and by 32% in subject 2, and postural stability and speech improved. The protocol was well tolerated, but the sham was not consistently believable. Conclusion: Cerebellar rTMS may improve postural stability and speech in PSP, but cooled coils with vibrotactile sham capability are needed for larger future studies.
