INTRODUCING THE NEW ACTIWATCH SPECTRUM AND ACTIWATCH 2

The new Actiwatch Spectrum and new Actiwatch 2 are wrist- worn ambulatory devices that document sleep/wake history over days or weeks at a time. The devices incorporate accelerometry technology and are capable of recording subject movement, light exposure and additional measures in a time series.

ACTIGRAPHY IMPLEMENTATION AND USER SATISFACTION

The new Actiwatch devices incorporate advanced aesthetics and functionality to help address a lot of the common complaints about using actigraphy. The Actiwatch system can be implemented by clinicians and patients with a minimum amount of training. Automated processes to retrieve data and generate research reports require only a few minutes of technician time. And, comfortable watch bands enhance the user experience.

FRESHLY REDESIGNED AND READY TO WEAR

The Actiwatch devices have been redesigned to help enable patient compliance while providing advanced functionality for clinicians and researchers. They are distinct and sleek in appearance and stand out from other ambulatory devices. Made for virtually anyone to wear, they are similar to a small digital watch. Data is downloaded from the devices using our powerful, analytical software, Actiware.

STATES OF SLEEP AND WAKEFULNESS ACCURATELY IDENTIFIED

Multiple clinical research studies have been published to compare the outcome measures derived from actigraphy and polysomnography, and actigraphy and diaries, for different patient populations in short-term sleep studies with varying results. Agreement rates for the scoring of individual epochs by actigraphy and PSG have been published showing correlation rates in excess of 90%.

KEY TECHNOLOGICAL ADVANCEMENTS FOR CLINICAL APPLICATION

Recent development of off-wrist detection, multicolored light exposure recordings and automated identification of major and minor periods of rest are key technological advances that will enable Actiwatch to be more easily applied in clinical practice and should help make new areas of research possible.
