Used to investigate complaints of excessive sleep time, irregular sleep patterns and excessive daytime sleepiness, Actigraphy is a simple test that measures the 24 hour activity of an individual typically for 14 days.

Often referred to as the gold standard measurement of sleep, this test is used to investigate a broad range of sleep disorders and complaints including limb movement disorder, insomnia, parasomnias, and other uncommon sleep conditions.
The test allows physiologists to measure brain wave activity, muscle tone, limb, and eye movements as well as the respiratory channels measured in the ambulatory overnight oximetry. This study involves a video recording.
At the Cromwell, we offer this test as either an inpatient for a single night admission to our sleep room, or in the comfort of your own home (limited by proximity to Cromwell).
Used to diagnose central hypersomnia’s including Narcolepsy, this test involves a single night and day admission to our sleep room.
The study involves a polysomnography followed by 4-5 scheduled naps performed throughout the day. The aim of the study is to get an objective measurement of sleepiness.
The polysomnography is performed to rule out any possible causes of sleepiness and to ensure a reasonable sleep time has been achieved.
Performed as an inpatient, this study involves measuring transcutaneous CO2 in conjunction with the channels involved in ambulatory overnight oximetry. This study is suggested in patients with underlying respiratory illness and/ or those using non-invasive ventilation.
