Model-Based Analysis of Muscle Strength and EMG-Force Relation with respect to Different Patterns of Motor Unit Loss

Figure 1

(a) The simulated relation between the excitation level and the motor unit firing rate for the “onion skin” firing strategy. (b) The simulated relation between the excitation level and the motor unit firing rate for the reverse “onion skin” firing strategy. (c) The twitch parameter assignment for the entire pool of 120 motor units.
