Actigraphy is a simple and reliable non-invasive ambulatory measure of activity and sleep/wake patterns over time.  Actigraphy devices use accelerometers to measure movement over a period of time.  Data can be recorded over multiple days in the patient’s own environment to provide an objective record for tracking and documenting normal and abnormal activity or sleep/wake patterns.

Actiwatch and Actical, are all actigraphy products.  They are specifically designed to measure activity or sleep/wake patterns with other parameters and have individual software packages to analyse the data.

Actiwatch is designed to monitor sleep/wake patterns to help identify and monitor Circadian Rhythm Disorders, Insomnia, Shift work disorders, Depression/Bipolar, Hyper somnolence ad Paediatric sleep patterns. Sleep patterns from the actiwatch are show below.
