Brief summary
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
Detailed description
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.
Interventions
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from International Cooperative Ataxia Rating Scale (ICARS) | per session: at baseline and within 30 minutes tDCS treatment completion | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change from temporospatial parameters of gait | per session: at baseline and within 30 minutes tDCS treatment completion | Gait parameters measured by GAITRite system |
| Change from posturography | per session: at baseline and within 30 minutes tDCS treatment completion | Posturography measured by Pedoscan system |
