Can a smartwatch decode Parkinson's symptoms?
NCT ID NCT05904288
First seen Sep 10, 2026 · Last updated Sep 11, 2026 · Updated 1 time
Summary
Researchers are testing whether data from a commercial smartwatch and a mobile app can help personalize treatment for Parkinson's disease. The study enrolls 54 adults with Parkinson's who take levodopa and experience daily motor fluctuations. Participants wear a Garmin Vivosmart 5 smartwatch and use a mobile app to record symptoms for six months. The goal is to develop machine learning algorithms that predict motor symptom scores from sensor data, which could one day help doctors adjust medication plans remotely.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- smartwatch and mobile app for monitoring Parkinson's symptoms
- What this could lead to
- If the algorithms work, doctors could use everyday smartwatch data to adjust Parkinson's medication more precisely and remotely.
- What could go wrong
- This is a small, early observational study. The algorithms may not predict symptoms accurately enough for clinical use, and results might not apply to all Parkinson's patients.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Written informed consent (IC) obtained. 2. Age \> 18 years. 3. Male or female patients Meeting the MDS clinical diagnostic criteria for Parkinson's Disease (Postuma et al., 2015) 4. At least one motor symptoms OFF-period each day, excluding early morning akinesia. 5. On treatment with Levodopa 6. Stable Levodopa regimen for 4 weeks before Screening Visit; 7. Levodopa Equivalent Daily Dose (LEDD) \> 400 mg, AND/OR Levodopa Intake \> 2 administration/day; 8. The subject is willing and able to attend study procedures and to use wearable and mobile devices. Exclusion Criteria: 1. Secondary or atypical PD. 2. Cognitive problems which significantly impair his/her ability to give an IC and perform the study tasks. 3. Levodopa Equivalent Daily Dose (LEDD) \> 800 mg, AND/OR Levodopa intake \> 8 administration/day; 4. Any condition that in the opinion of the investigator would interfere with the interpretation of the study results or constitute a health risk for the subject if he/she takes part in the study. 5. Concomitant participation to clinical trials with investigational medicinal products. 6. Failure to show, in opinion of the investigator, acceptable/appropriate use of wearable and mobile device (e.g. weekly average daily wearable wear time \< 8 hours). Having an advanced treatment (including Deep Brain Stimulation, Apomorphine, Duodopa), is not an exclusion criterion, as well as the subject decision or capability to attend the exercise and speech training programs within the mobile app.
