Parkinson's disease (PD) can make walking difficult. People with PD often create their own ways to help them walk better. There are two main strategies: external cueing and internal cueing. External cueing involves using outside signals like a metronome, while internal cueing involves using mental tricks like counting steps. However, these strategies work differently for everyone. This study, called the UNITE-PD project, aims to understand how these strategies help over time and why they work better for some people than others. Researchers will use a special app to track these changes for six months. The study will include 384 people from different countries.

• This study lasts for six months.
• Participants must be able to walk for more than three minutes without help (except for a cane).
• People who already use compensation strategies daily can't join.
