Assessment of Tremor Using SNUMAP Motion Sensing System (SNUMAP)

July 7, 2015 updated by: BS Jeon, Seoul National University Hospital

Quantitative Assessment of Tremor Using Portable Six-axis (Tri-axial Accelerometer and Tri-axial Gyroscope) Motion Sensing System

The purpose of this study is to record and measure tremor using portable six-axis (tri-axial accelerometer and tri-axial gyroscope) motion sensing system.

Detailed Description

SNUMAP system is portable, finger-worn, battery powered device that contains MEMS (micro-electro-mechanical system) hybrid motion sensor (three-axis accelerometer and three-axis gyroscope). The SNUMAP device consists of a wrist module and finger module, which attaches to an patients's finger and transmits three dimensional motions to a wrist module for storage and further analysis. The aims of this study is to assess tremor severity using tri-axial accelerometry and gyroscope to determine the reliability and the correlation with clinical measurements.
