What is ActiGraph Link?

ActiGraph’s GT9X Link is a wearable device designed for clinical and research use, collecting comprehensive actigraphy data to monitor physical activity, sleep patterns, and movement behaviors. Though discontinued in August 2023, the GT9X Link remains a pivotal tool in ongoing clinical studies, with continued support and inventory provided by ActiGraph for existing research projects. Known for its accuracy and data reliability, the device has served as a foundation for research in health behavior and chronic disease management, especially in studies focusing on sleep disorders and mobility challenges.

Key Features:

• Multisensor Data Collection: The GT9X Link is equipped with a 3-axis accelerometer, allowing it to record detailed data on physical activity and sedentary behavior, making it particularly useful in studies involving chronic illness and mobility impairments.

• High Storage Capacity: With up to 1 GB of data storage, the GT9X Link can store weeks of high-resolution data, reducing the frequency of data uploads and easing study workflows.

• Compatible with ActiLife Software: The device works seamlessly with ActiGraph’s ActiLife software, allowing researchers to analyze movement and activity data effectively.

• Support for Clinical Research: The GT9X Link has been widely used in public health and academic research studies, providing validated digital health technology for remote and continuous monitoring.

Summary:

ActiGraph GT9X Link remains a strong research tool for those already using it, offering detailed data on activity and sleep behavior that supports a range of clinical and public health studies. While new users are directed to ActiGraph’s LEAP or CPIW models, the GT9X Link continues to serve ongoing research with ActiGraph’s committed support and maintenance.
