Smartwatch Versus Routine Tremor Documentation: Descriptive Comparison

Abstract

We addressed the limitations of subjective clinical tremor assessment by comparing routine neurological evaluation with a Tremor Occurrence Score derived from smartwatch sensor data, among 142 participants with Parkinson disease and 77 healthy controls. Our findings highlight the potential of smartwatches for automated tremor detection as a valuable addition to conventional assessments, applicable in both clinical and home settings.

Keywords: Parkinson disease; mobile apps; movement disorders; smart wearables; smartwatch; tremor; tremor documentation; tremor occurrence; tremor score.

Boxplots of Tremor Occurrence Scores (TOSs) for all participants grouped by their routine tremor documentation. Each data point represents a participant of the respective group. Points are colored according to the average wrist amplitude in grams. The middle line is the median. The top and bottom sections are upper and lower quartiles, respectively. The box represents the middle 50% of TOSs for the group. The upper and lower whiskers represent scores outside the middle 50%. PD: Parkinson disease.
