The ActiGraph ActiSleep disposable wrist straps are designed for short-term use in clinical trials or research settings, particularly for sleep or activity monitoring. These hospital-style wristbands securely hold the ActiGraph device in place, helping to prevent participants from removing it and ensuring continuous, reliable data collection. Compatible with ActiGraph models wGT3X-BT, wGT3X+, and GT3X, each strap is intended for single-use over a period of up to 72 hours. For safety and accuracy, straps must not be altered or reused. This 20-pack provides a convenient solution for maintaining device placement across multiple participants.
