Polysomnography (PSG) is a type of sleep study which includes multi-parametric testing during sleep in the prescence of a sleep physiologist. The PSG monitors many body functions, including brain activity (EEG), eye movements (EOG), muscle activity or skeletal muscle activation (EMG), and heart rhythm (ECG), during sleep.

Your Physician may request a PSG study if they suspect conditions which may include the following:

  • Sleep apnea or another sleep-related breathing disorder. In this condition, your breathing repeatedly stops and starts during sleep.
  • Periodic limb movement disorder. In this sleep disorder, you involuntarily flex and extend your legs while sleeping. This condition is sometimes associated with restless legs syndrome.
  • Narcolepsy. You experience overwhelming daytime drowsiness and sudden attacks of sleep in this condition.
  • REM sleep behavior disorder. This sleep disorder involves acting out dreams as you sleep.
  • Unusual behaviors during sleep. Your doctor may perform this test if you do unusual activities during sleep, such as walking, moving around a lot or rhythmic movements
  • Unexplained chronic insomnia. If you consistently have trouble falling asleep or staying asleep, your doctor may recommend polysomnography.

If your Physican has recommended a PSG study, please get in touch to discuss how LRS can provide this within the home enviroment.
