Table 4.

Similarity of model parameter values between the two approaches. Similarity was quantified using the mean and standard deviation of values for Approach B relative to Approach A. Similarities are reported as percent differences for optimal muscle fiber lengths $l_0^M$ and tendon slack lengths $l_s^T$ and as absolute differences for activation scale factors sa and moment arm deviations ma_dev. Statistically significant differences (p < 0.05) in each quantity are indicated by an asterisk (*).
