This study is focused on helping people with Parkinson's disease (PD) improve their ability to start walking, which is often difficult due to problems with anticipatory postural adjustments (APA). APAs are the body's way of preparing to move. The study uses a special training system that helps people learn how to improve their APAs. The training is designed using something called explicit learning, which is easier for people with PD.

The study also tests a method called Paired Associative Stimulation (PAS). PAS is used to make the brain's motor cortex, the part that controls movement, more active. This could help with learning better APAs.

• Duration: The study's length and number of visits are not specified, but participants will undergo specific training sessions.
• Eligibility: Must have a clinical diagnosis of Parkinson's disease. Cannot have leg injuries, osteoporosis, or other nervous system issues.
• Risks: No specific risks mentioned, but general study participation risks apply.
