Evaluation of head posture using an inertial measurement unit [PDF]
Scientific Reports, 2021 AbstractAn inertial measurement unit (IMU) is an electronic device that measures and track the orientation of a body. We conducted this study in accordance with the STARD guidelines to evaluate the accuracy of IMU (index test) for measuring head posture compared to the current gold standard using a cervical range of motion (CROM) device.
