This study focuses on Parkinson's Disease (PD), a disorder that affects brain function, causing problems with movement and balance. This study takes place in Galicia, Spain, where many people have PD, but there's limited information about how it affects their daily lives. The goal is to gather information about people with PD and see if a test called the Short Physical Performance Battery (SPPB) is useful. The SPPB measures how well people can balance, walk, and stand up from a chair, which are all important for everyday life.

Participants will complete various tasks while wearing special sensors to collect data on how they move. This study does not involve treatment, but it will help doctors understand more about PD and how to help people live better with the disease.

• Study Duration: Participants will complete assessments during one phase of their medication.
• No Treatment: This is an observational study, meaning it does not involve any new treatments.
• Eligibility: Must have a confirmed PD diagnosis and consent to participate.
