In Vivo Dynamics of the Musculoskeletal System Cannot Be Adequately Described Using a Stiffness-Damping-Inertia Model
Figure 2
Four examples of responses of the MSM (φMSM) and optimized responses of the KBI-model (φKBI).
The table on the right-hand side depicts the MSM parameters used and the optimized stiffness K and damping B of the KBI-model. A. Impulse responses of the MSM and optimized KBI-model. B. Same as in A, but now a sinusoid torque wave was used as a perturbation, instead of an impulse. C. Impulse response same as in A, but now the time interval over which the parameters were optimized was set to 100 ms instead of 50 ms. D. Typical example of an impulse response of the MSM for which the optimized KBI response showed marked differences.
