Study Overview: This study is for patients with moderate-stage Parkinson's Disease (PD). PD is a brain disorder causing symptoms like stiffness and slow movements. The study will test a new treatment called vibrotactile stimulation, which sends gentle vibrations to the skin to help improve movement.

Treatment Details: Participants will use a device at home that provides vibrations for up to four hours daily. The device can be used in two, two-hour sessions to fit into their daily routine. This treatment is non-invasive, meaning it doesn't require surgery. The study will last for at least four months, but participants can continue longer if they choose.

Eligibility: To join, you must be between 45 and 90 years old, have moderate-stage PD, and not take certain medications. This study offers support to participants as they adjust to the treatment.

• Duration: Daily home-based treatment for four months, with the option to continue.
• Flexibility: Sessions can be divided into two blocks for convenience.
• Safety: Support available for any issues with the device.
