Transcranial Magnetic Stimulation in Progressive Supranuclear Palsy is a study looking at how a special treatment called repetitive cerebellar transcranial magnetic stimulation (rTMS) might help people with a condition called Progressive Supranuclear Palsy (PSP). PSP is a disease that affects balance and movement. The study uses rTMS, which is a non-invasive treatment that doesn't require surgery. The treatment might help improve balance by sending magnetic waves to the brain. The researchers will also use a tool called functional near infrared spectroscopy (fNIRS) to see how the brain changes with this treatment.

• The study is for people aged 40-85 who have been diagnosed with PSP.
• Participants need to be able to follow simple instructions and stand for at least 30 seconds without help.
• Participants must avoid new physical or speech therapy and stay on stable doses of certain medications during the study.
