Brief Summary:
The purpose of this study is to develop statistical and informatics tools for analyzing and visualizing Actical™ (actigraphy) data linked to fatigue in Sleep Medicine Center patients.

Condition or disease
Obstructive Sleep Apnea Restless Leg Syndrome Insomnia

Detailed Description:
An Actical™ is a watch-like device attached to the wrist that uses an accelerometer to measure movement nearly continuously over several days. The American Academy of Sleep Medicine practice parameters report that actigraphy is a useful tool for detecting sleep in healthy individuals, assessing specific aspects in insomnia and restless legs syndrome, circadian-rhythm disorders, and excessive sleepiness. Concurrent with these recommendations is an increased interest in the use of actigraphy as a tool for objectively measuring fatigue. With improved high-end statistical methods for analyzing this data, actigraphy has the potential to become more important as an objective diagnostic tool for determining fatigue, sleep abnormalities and assessing response to treatment.
