A wearable sensor that measures body movement, acceleration, and orientation.
An IMU is a small electronic device, typically combining an accelerometer, gyroscope, and sometimes a magnetometer, used to capture movement data such as speed, acceleration, rotation, and change of direction. In sports science and rehab, IMUs are attached to the body or equipment to quantify training load, movement quality, or gait characteristics outside the lab. Accuracy and validity vary by device, sensor placement, and the specific metric being derived, so findings should be interpreted with attention to the validation evidence for that particular unit and algorithm.
