The wGT3X-BT is ActiGraph’s flagship activity monitor, used by researchers around the world to capture and record continuous, high resolution physical activity and sleep/wake information.

How much does an ActiGraph cost?

The NAPL reports there is no cost to use their ActiGraphs. However, the cost to purchase an ActiGraph is around $250. Researchers may need to plan to include replacement costs as the monitors may be broken with use.

What is ActiGraph accelerometer?

Actigraphs are small motion sensor detectors (accelerometers) that are encased in a unit about the size of a wristwatch and can be worn continuously for days to months. Actigraphy does not measure sleep per se, but rather level of activity, which is highly correlated with sleep.

What does an ActiGraph measure?

An actigraph is worn like a watch on the wrist of your non-dominant hand and measures activity through light and movement. Actigraphy data can be very helpful for assessing circadian rhythm disorders such as advanced or delayed sleep phase disorder and insomnia.

How do you wear an ActiGraph?

You should wear the Actigraph on your non-dominant wrist (i.e. if you are right handed please wear the Actigraph on your left wrist).

Is the ActiGraph waterproof?

The ActiGraph Link is water resistant in accordance with IEC 60529 IP27, or immersion in one (1) meter of water for up to 30 minutes. All ActiGraph products are manufactured Lead Free and are RoHS Compliant. U.S. federal law restricts this device to sale by or on the order of a physician.

What can ActiGraph measure?

Is ActiGraph the same as accelerometer?

Actigraphy is the process of measuring physical movement of an individual over time to assess the degree of motor activities. According to the manufacturer’s website, the Actiwatch utilizes a motion sensor known as an “accelerometer” to monitor the occurrence and degree of motion and produces a small signal.

What is an ActiGraph sensor?

Actigraphy is a non-invasive method of monitoring human rest/activity cycles. A small actigraph unit, also called an actimetry sensor, is worn for a week or more to measure gross motor activity. The unit is usually in a wristwatch-like package worn on the wrist.

Is fitbit an ActiGraph?

Comparison of wrist-worn Fitbit Flex and waist-worn ActiGraph for measuring steps in free-living adults. Introduction: Accelerometers are commonly used to assess physical activity. Consumer activity trackers have become increasingly popular today, such as the Fitbit.

What is an activPAL?

The activPAL™ (AP) activity monitor is a small device worn on the thigh that uses information about static and dynamic acceleration to 1) distinguish body posture as sitting/lying, standing and stepping and 2) estimate energy expenditure (EE) (expressed as metabolic equivalents (METs)) (34).
