The aim of study is to investigate most effective site for control the motor coordination using transcranial direct current stimulation in multiple system atrophy with cerebellar feature
Participants receive transcranial direct current stimulation (tDCS) over M1, cerebellar cortex or sham stimulation for 30 minutes. The type of stimulation depends on random assignment. The participants have a 1 week of wash out period between each stimulation.
The assessment will be done by International Cooperative Ataxia Rating Scale (ICARS), GAITRITE (CIR Systems Inc., Clifton, New Jersey, USA) and PEDOSCAN (DIERS PEDO, Germany) at baseline and immediately after each treatment.

| transcranial direct current stimulation | Device | tDCS involves application of very low amplitude direct current via surface scalp electrodes. The applied current modifies the transmembrane neuronal potential and thus influences the level of excitability. Depending on the polarity of active electrodes tDCS can increase or decrease the cortical excitability. |
| Measure | Description | Time Frame |
|---|---|---|
| Change from International Cooperative Ataxia Rating Scale (ICARS) | The scale is scored out of 100 with 19 items and 4 subscales of postural and gait disturbances, limb ataxia, dysarthria, and oculomotor disorders. Higher scores indicate higher levels of impairment. | per session: at baseline and within 30 minutes tDCS treatment completion |
| Measure | Description | Time Frame |
|---|---|---|
| Change from temporospatial parameters of gait | Gait parameters measured by GAITRite system | per session: at baseline and within 30 minutes tDCS treatment completion |
| Change from posturography | Posturography measured by Pedoscan system |
