Actigraphy


Find Sleep Clinics & Specialists »

Actigraphy is used in treatment for sleep disorders to monitor an individual’s movement over a period of 24 hours. The patient will wear a watch-like actigraph on their wrist or ankle and the machine will monitor periods of sleep throughout the day. It is an efficient way of monitoring the time asleep and awake for a particular person, and may be more beneficial than writing a sleep diary. Often used for people who are suffering from circadian rhythm disorders, the actigraph is a simple and non-interrupting method of monitoring sleeping patterns. All normal daily activities can be carried out whilst wearing the actigraph. It is also thought that actigraphy is a useful method of monitoring insomnia cases and for testing methods for better sleep.
