When is Actigraphy Useful for the Diagnosis and Treatment of Sleep Problems?

Actigraphy is an ambulatory study that captures sleep-wake patterns for up to two weeks in the patient ’s natural sleep environment.[1] An actigraph is a wrist-watch sized device that measures movement with an internal accelerometer, and works under the premise that movements are frequent and large when we are awake, but absent or small when we are asleep. What separates actigraphs from consumer we arable devices are the validated algorithms, developed through side-by-side comparisons with polysomnography, the gold standard for sleep assessment.
