Scientists of the EU-funded DiPAR (Diagnosing Parkinson’s disease by neuromuscular function evaluation) project developed a digital sensor pen. This device records biomarkers non-invasively to enable differential diagnosis and monitoring of PD.

Using data from PD patients and healthy individuals, scientists determined baseline values for key motion parameters. They then designed a functional discrimination script to automatically differentiate between healthy and PD patients. Via movement related sensors, the pen records minute motions of the hand and quantifies fine motor skill based on motion features.

Besides being non-invasive, the DIPAR pre-production prototype is user-friendly and doesn’t require highly specialized neurologists for patient assessment.
