Validity and repeatability of inertial measurement unit for measuring walking gait parameter of patients with non-specific low back pain

Introduction: The Inertial Measurement Unit (IMU) is electronic device that enabled us to record joint angles, gait event and spatiotemporal parameter using accelerometers. IMU contain sensors known as inertial sensor which measures its movement by using the inertia principle. This study aimed to de...
