Using Multi-Sensor System for Measuring Finger Trembling, and Applied to Neurodegenerative Disease

Finger trembling is a feature for neurodegenerative diseases. Accessing the trembling of fingers can help diagnosis or monitoring of progression of the disease. Currently, tremogram is used in the hospital to measure the trembling of a finger. Tremogram is a single and uniaxial acceleration gauge. Using the tremogram, only the trembling direction of a finger can be measured. The direction and the finger are determined by the physician. This work studied the possibility to employ the Leap Motion and the G-sensor/gyro to access the trembling of the five fingers. Experimental results demonstrated positive answers that a G-sensor/gyro system can access not just only those information obtained from the tremogram, we can derive more information.
