Assessment of Tremor Using SNUMAP Motion Sensing System
Assessment of Tremor Using SNUMAP 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.
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.
Inclusion Criteria:

 -  Age: 20-80 years

 -  Patients with tremor (involuntary, rhythmic, oscillatory movement in one or more body
 part)

 -  Subject who signed an informed consent

 Exclusion Criteria:

 -  Pregnant or nursing woman.

 -  Comorbid neurologic illnesses that impact the ability to perform the study tasks.

 -  Subjects with medical condition that in the opinion of the investigator would affect
 his/her ability to participate in this study.
