This study checks if a special brain treatment, called *transcranial direct current stimulation* (tDCS), helps people with a rare brain disease called Multiple System Atrophy-Cerebellar Variant (MSA-C). MSA-C affects movement and balance. The treatment uses weak electric currents on the scalp to help the brain work better.

Participants will be divided into two groups and get either real or pretend treatment for two weeks. Each session lasts 20 minutes. We will check if the treatment improves balance and movement using special tests and ask participants how they feel.

• The study lasts two weeks, with sessions from Monday to Friday each week.
• 15 participants are needed for each group.
• Participants must be able to walk with little or no help.

To join, you should not have any electrical devices in your body, should understand Italian, and should not have certain health issues like severe heart problems or a history of seizures. Pregnant individuals cannot participate.
