The study aims to see if a special technique called temporal interference stimulation (TIS) can help people with Parkinson's disease (PD) improve their movement issues. Parkinson's disease is a condition that affects movement and causes symptoms like slow movement, stiffness, and difficulties walking. TIS is a method that involves sending electrical signals to the brain. The study will compare TIS to a sham treatment, which looks the same but doesn't provide real stimulation. Participants will use the TIS at home once a day for four weeks, with remote supervision. They will also visit the clinic for movement tests and fill out online surveys about their health and quality of life.

• The study lasts for 4 weeks, with daily home sessions.
• Clinic visits are required for movement assessments.
• Participants will fill out online questionnaires.

Note: To join, you must be between 40 and 80 years old, have mild-to-moderate PD, and meet other criteria. Some medical conditions, like having a pacemaker or severe arthritis, may prevent participation. Please ensure you understand the study and are willing to participate before enrolling.
