Actigraphy is a non-invasive method for sleep/wake monitoring, rest activity rhythm
measurement, and daytime activity assessment. It has been actively used in sleep-
related studies since the early 1990s, and is used to replace full polysomniography
for insomnia evaluation. The main reason is that as opposed
to staying in a lab overnight for polysomniography, the patient remains mobile and
can remain in his/her home and natural sleep environment, generating reliable
results with an accuracy that is close to those of polysomniography (above 90%). After
a complete evaluation, and based on the patients condition, Dr. Jaffery may ask you to
wear the actigraph watch.
Polysomniography is not recommended for routine assessment of insomnia, however
if there is a suspicion of certain sleep related disorders you will be referred for this
overnight in-lab procedure.
