Actigraphy provides a means for clinicians and researchers to measure sleep quality in individuals suffering from sleep disorders, such as insomnia, PLM, sleep apnea and others. An actigraph can also be used in many other applications. Click here to view a number of case studies using actigraphy.

Actiwatches are small, rugged, actigraphy-based data loggers that record a digitally integrated measure of gross motor activity. Each model of Actiwatch actigraph is equipped with a highly sensitive accelerometer as well as the ability to record data from a second input or sensor. This second input makes them very useful for a wide variety of research or clinical applications.

Actiwatch actigraphs come in the following models:

• AW-16 & AW-64 (with integral time mark generator)
• AW-L (with integral light sensor)
• AW-Score (with integral subjective scoring)

Actiwatch Applications

Activity level is recognized as a valuable indicator for medical problems and can provide answers to many research questions. Activity levels correlate with sleep/wake patterns, pain level, mood, energy expenditure, fatigue/alertness and other quantifiable parameters. An Actiwatch actigraph also provides an objective record for tracking and documenting normal and abnormal sleep/wake patterns.

 

An example of the use of the Actiwatch is:

• Sleep/Wake Patterns

Sleep/Wake Patterns and General Activity Levels

A digitally integrated recording of wrist activity is a reliable indicator of Sleep/Wake state. The Actiwatch is an actigraphy device that is the size of a standard wrist watch. It allows for the recording of the smallest movements for days, weeks, or even months.

When worn on the wrist, an Actiwatch actigraph can generate an Activity record like the one shown below to be used as a tool to document:

• Sleep/Wake Patterns
• Sleep Disorders
• Circadian Rhythms Disorders
• Disturbances brought on by Shift Work
• Basic Activity Levels
• Compliance with Exercise Routines
