|Estimated Study Completion Date :||December 1, 2019|
Experimental: Transcranial Magnetic Stimulation (TMS) Stimulation
All patients will receive 5 sessions of active TMS stimulation.
Device: Transcranial Magnetic Stimulation (TMS)
Low frequency (1Hz) transcranial magnetic stimulation aimed to the dentate nucleus contralateral to the most symptomatic side.
Sham Comparator: Sham Stimulation
All patients will receive 5 sessions of active TMS stimulation
Device: Sham Stimulation
The stimulation coil will be placed in the same spot as the TMS stimulation, but coil will not be attached to the TMS machine.
- Percent Change From Baseline to Post Treatment on the Scale for the Assessment and Rating of Ataxia (SARA) [ Time Frame: Day 1 (baseline), day 5 (after 5th TMS session, active or sham), day 33 (new baseline after TMS wash out) and day 38 (after 10th TMS session, active or sham) ]Assess 8 items: gait, stance, sitting, speech, dysmetria, kinetic tremor, pro- and supinations of the hand, and the heel-shin slide. Each item is scored by the physician on a 4 to 8 numerical scale based upon the amount of dysfunction observed while performing the task. The maximum possible score for the total scale is 40. Lower scores of SARA represents better task performance.
