A full night sleep measured with polysomnography may be required for some sleep disorders. Indeed, actigraphy may be efficient in measuring sleep parameters and sleep quality, however it is not provided with measures for brain activity (EEG), eye movements (EOG), muscle activity (EMG) or heart rhythm (ECG).

The Tracker measures steps taken as well as user data to calculate distance walked, calories burned, floors climbed, and activity duration and intensity. It uses an OLED display to display this and other information such as the battery level. It also measures sleep quality by tracking periods of restlessness, how long it takes the wearer to ...
The sleep diary, or sleep log, is a tool used by doctors and patients. [1] [2] [3] It is a useful resource in the diagnosis and treatment of especially circadian rhythm sleep disorders, and in monitoring whether treatment of those and other sleep disorders is successful. Sleep diaries may be used in conjunction with actigraphy.

Consisting of 19 items, the PSQI measures several different aspects of sleep, offering seven component scores and one composite score. The component scores consist of subjective sleep quality, sleep latency (i.e., how long it takes to fall asleep), sleep duration, habitual sleep efficiency (i.e., the percentage of time in bed that one is asleep), sleep disturbances, use of sleeping medication ...

To measure sleep variables candidly, patients wear actigraphy watches that record sleep onset, wake time, and many other physiological variables. Patients are similarly asked to self-report their ...
The SWAI has been compared to the multiple sleep latency test (MSLT), which is an objective measure that is considered the gold standard of sleepiness assessment; it measures sleep onset latency during several daytime opportunities. The SWAI-EDS has been found to correlate moderately to highly with average MSLT scores.
