Abstract
The amount of inertial measurement unit (IMU)-based motion analysis systems on the market rises. Due to lower costs and easier usage, these systems offer an alternative to optoelectronic systems. Previous studies showed differences between IMU-based and optoelectronic systems during gait. This study evaluates the measurement accuracy of 3D lower limb joint angles of the IMU-based measurement system MyoMotion during different motion tasks. Therefore, 12 healthy subjects are investigated during level walking, sloped walking and climbing stairs. Differences in the results are observed in the biomechanical model. Moreover, the movement velocity causes differences between both measurement systems. Especially during more complex and faster movements, these differences increase.
