Determining Minimum Wear Time for Mobile Sensor Technology

Optimize your clinical trial outcomes by defining effective minimum wear time for wearable devices. This expert analysis provides essential guidance for determining what constitutes a valid data set when using mobile sensor technology in your studies.

Drawing from extensive literature review, it addresses critical considerations including minimum data requirements, risks of missing data, alignment with clinical endpoints, and managing patient burden to ensure robust, reliable results.

For example, when measuring overall daily activity like total steps, researchers typically recommend at least 80% of data should be available (non-missing) for valid analysis. However, requirements vary by endpoint – measuring real-world walking speed may require less wear time than capturing total daily activity patterns.
