Abstract



Movement
analysis is widely used to gain insights into human health and motor control.
Especially walking and running are examined in medical diagnostics,
rehabilitation and performance assessment in sports. Inertial measurement units
(IMUs) enables an ambulatory assessment of kinematics or kinetics. The
challenge is to obtain a detailed analysis based on noisy data, sensor drift
and a limited number of sensors. Current methods focus on kinematic parameters
only or additional sensors had to be applied for kinetic analysis.
Alternatively, ground reaction forces had to be estimated.



We propose an
optimal control simulation of a 2D musculoskeletal model to simultaneously
obtain kinematics and kinetics of the lower body using seven IMUs. The sum of
squared differences of measured and simulated inertial data and the neural
excitation of the muscles are minimized. This method is evaluated against an
optical motion capture method for 2D walking and running.
