A wrist-worn device may provide a clearer and more consistent picture of tremor in Parkinson’s disease than what can be seen during a single clinic visit or recalled from memory alone, a study has found, adding to evidence that wearable sensors can help track motor symptoms in daily life.
When worn for a few days, Axivity’s AX6 movement sensor, embedded in a wristband, offered “additional insights” into tremor features, especially how long tremor episodes lasted and how strong they were, even in cases where a doctor’s clinic observations did not match what patients reported.
The study, “Added value of a wrist-worn device for assessing tremor in Parkinson’s disease: reliability and validity of tremor evaluation at home,” was published in npj Parkinson’s Disease by researchers at Leiden University Medical Center in the Netherlands.
