This type of sleep study helps to determine your level of alertness during the day and your ability to stay awake for a certain period of time.
 

The MWT is another test done during the day following a PSG. Again, sensors are placed on the scalp, chin, and face and measure when you are awake and when you are asleep. The test involves sitting quietly in a comfortable chair and looking straight ahead for a certain number of minutes, usually at least forty, and gets repeated four times. During these trials, you try to stay awake. If you do fall asleep, the technician doing the recording will let you sleep for about 90 seconds before waking you up. There are two-hour breaks in between the trials.
 

The goal of the MWT is to determine how awake you stay throughout the day and whether or not you are putting yourself in danger if you have a tendency to fall asleep. The MWT can also be used to help determine how you are responding to any treatments you are receiving for sleep disorders.

After having a PSG, multiple sleep latency test, or maintenance of wakefulness test, the sensors get removed and you are free to go home.
