Keeping a watch on Parkinson’s disease

Smartwatches can capture continuous motor activity and physiologic metrics and could be useful for remote patient monitoring. Powers et al. developed a smartwatch-based ambulatory monitoring system to track dyskinesia and resting tremor in patients with Parkinson’s disease. Smartwatch-detected tremor and dyskinesia matched clinician-reported evaluations seen during in-clinic visits. The smartwatch-based system could identify changes in symptoms resulting from better adherence to medication or deep brain stimulation treatment, as well as subclinical symptoms, suggesting a need for alternative treatment or medication titration. This study demonstrates the potential utility of smartwatch-based remote monitoring for Parkinson’s disease.
