IMU Step removes the guesswork from an injured athlete’s Return-to-Play journey. Small, synchronized, high-frequency waterproof sensors are placed on the interior of the left and right ankles delivering load metrics to running sports athletes. It enables precise, actionable insights, identifying and quantifying the impact of each step, helping monitor and identify asymmetries of the lower limbs via cloud based dashboards. With IMU Step iOS, you can select the athlete who is training, add contextual information on their session, and view live data on an Apple device streamed directly from the sensors. Live metrics such as intensity are calculated and displayed in real-time, alongside the ability to record and save video footage of your session. You can also download data recorded by the sensors using IMU Step Desktop for PC and Mac for analysis via the IMU Step online dashboard. IMU Step iOS is only compatible with IMeasureU’s BlueTrident Inertial Sensors running firmware 10.0.1 and above. ## Key features - Real-time load metric analysis - Lower limb asymmetry identification - Cloud-based dashboard insights - Live data streaming - Session video recording - Sensor data download ## Frequently asked questions about IMU Step ### What is IMU Step used for?
