Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary factor to be investigated is the difference in tremor frequency (DBS OFF - THS ON) | — |
Secondary
| Measure | Time frame |
|---|---|
| Difference in Tremor Power (DBS OFF-ON) Occurrence of nystagmus when the stimulation is switched off Relevant diseases: other cerebellar ataxia, impairment of the affinity to the cerebellum (spinal ataxia, polyneuropathy) Age Pallesthesia of the right and left lower extremity Stimulation parameters (localization, amplitude, frequency, pulse width) Handling of the stimulation by the patient Demand-adapted reduction of the stimulation during the day (yes vs. no)? night-time reduction of stimulation (yes, night switch-off vs. yes, night-time reduction vs. no)? | — |
