PD Trends APP

PD-Trends is an intuitive app designed to help Persons with Parkinson’s Disease (PwPD), their caregivers, and clinicians track and understand symptom patterns and trends. It plans to combine tremor, dyskinesia, movement, sleep and heart rate data from your smartwatch with a simple diary where you log changes in medication, diet, stress, and other events. By correlating these factors, PD-Trends provides a clearer picture of how daily habits and interventions affect your symptoms.

Using the Apple Watch MM4PD API (Powers et al., 2021) and data from the Apple iPhone Health app, the app generates detailed graphs on your smartphone with resolutions ranging from 10 minutes to weeks and either as raw data or averaged per hour, day, week or 4-week period to enhance the visualization of relevant trends. Currently, data can be exported to a secure cloud location for a deeper expert analysis on a computer with a spreadsheet tool. We are planning to also make a similar app available for the Android platforms operating for example with Garmin or Samsung watches. However, for that we are seeking funding and collaboration with RadboudUMC in the Netherlands, but we are open for other additional options as well and invite iinternational collaborations!

Key Features:

• Symptom Tracking: Visualizes tremor, dyskinesia, movement and sleep over time, from minutes to years. See progression, daily or weekly patterns, and the effects of interventions. Planning to include heart rate parameters and exercise as well
• Daily Diary: Color-coded tremor and movement levels (green = mild, red = strong) alongside notes tracking medication, supplements, diet, exercise, and stress (to be implemented).
• Comparative Analysis: Compare two time periods to see how symptom patterns change with new treatments, lifestyle adjustments, or events (to be implemented in the analysis report).
• Long-Term Trends: Track and understand fluctuations in your symptoms over weeks, months, or years. Focus on specific symptoms that best reflect how you feel or how your medication works.
• Graphic Overlays: Visualize the impact of medication, exercise, diet, supplements, stress, holidays, steps, and sleep on symptom patterns (to be implemented).
• Data Access & Sharing: Download your full dataset for expert analysis and share automated analysis reports interpreted with AI with yourself, your clinician, or your social network (to be implemented).

Next versions of PD-Trends will:

• Add a diary option to log medication and events that explain symptoms
• Display interactive graphic overlays comparing periods directly on your phone for immediate visual insight.
• Include heart rate and heart rate variability as a potentially relevant symptom
• Automatically generate sharable summary reports with charts and AI-assisted interpretations.
• Expand compatibility to Android devices, making the app accessible to more users.

PD-Trends empowers you to take control of your Parkinson’s journey, providing actionable insights to improve daily life and support informed discussions with your healthcare team.
