Researchers from University of North Dakota (USA) have studied Parkinson’s disease tremor severity using signals acquired from Physilog sensors. Features calculated from signals produced by accelerometer and gyroscope sensors placed on the index finger and wrist were taken into account to quantify both resting and postural tremor.
