    Correlation between SNUMAP motion sensing system symptom assessment and clinical tremor rating scale (TRS) scores

Enrollment: 187
Study Start Date: August 2014
Study Completion Date: February 2015
Primary Completion Date: February 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: SNUMAP assessment
Uses SNUMAP motion sensing system to quantify tremor symptom.
Device: SNUMAP
Portable six-axis (tri-axial accelerometer and tri-axial gyroscope) motion sensing system
Other Name: Hybrid (accelerometer and gyroscope)

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.
