What this study is
The objective of this proposal is to investigate the effect of non-invasive repetitive cerebellar transcranial magnetic stimulation (rTMS) on motor control in progressive supranuclear (PSP). The central hypothesis is that augmenting cerebellar inhibition via cerebellar rTMS will decrease postural instability in patients with PSP. We will use functional near infrared spectroscopy (fNIRS) to examine changes in motor and premotor cortical activity after cerebellar rTMS.
What's being tested
- Repetitive transcranial magnetic stimulation (rTMS)
Intervention · DEVICE
Aim 1: To determine the clinical effects of rTMS targeting the cerebellum on postural instability in PSP. The hypothesis to be tested is that TMS augmentation of cerebellar inhibition will improve cerebellum-dependent balance symptoms of PSP for a period of time sufficient to improve rehabilitation outcomes. The investigators will measure a battery of objective posturography metrics and other measures of motor control, including sway and center of pressure changes to backward tilt and forward translation. Aim 2: We will use functional near infrared spectroscopy (fNIRS) to examine changes in motor and premotor cortical activity after cerebellar rTMS. The hypothesis to be tested is that premotor and motor cortical activity will decrease after cerebellar rTMS compared to sham TMS, reflecting improved cerebellar inhibition of the motor cortex after the intervention.
