Point of view: Wearable systems for at-home monitoring of motor complications in Parkinson's disease should deliver clinically actionable information.

• Management of Parkinson's disease (PD) relies on knowledge of the motor complication. • Commercially available devices for PD management have limited adoption. • The obstacle relates to the limitations of these devices' underlying algorithms. • Future algorithmic developments need to address the essential requirements.
