This study is testing a new system called the SensMode System. It uses wearable devices to measure how well people move their arms and legs. It's for healthy people, those with a smell problem called idiopathic hyposmia, people with Parkinson's disease, and those with a condition affecting movement called extrapyramidal syndrome. The goal is to find out if this system can help diagnose Parkinson's disease early and help manage the disease better.

• The study involves adults aged 50-80.
• Participants need to have good cooperation and no serious health issues that affect movement.
• Participants must agree to be part of the study and give informed consent.

Parkinson's disease is a condition that affects how people move, often causing shaking, stiffness, and difficulty with balance and coordination. The SensMode System might help doctors understand and treat these problems more effectively. Participants will wear devices that track their movements, and the data collected will help researchers see if this new technology can make a difference in diagnosing and treating Parkinson's disease.
