Figure 3From: Validation of the angular measurements of a new inertial-measurement-unit based rehabilitation system: comparison with state-of-the-art gait analysisKalman filter weights. Superimposition of flexion angle trajectories in a knee flexion against gravity exercise for different combinations of Kalman filter weights. Where ka, km and kg are the filter’s weights of the accelerometer, magnetometer and gyroscope respectively.Back to article page
