Locations and characteristics of poles associated with the open-loop system and a third-order Padé approximation of the closed-loop system. Summary statistics of the imaginary portion of poles were calculated using the absolute value of the imaginary portion. In calculating summary statistics of natural frequency and damping ratio, real poles were excluded.

Excess of Central Delay values (in milliseconds) reported in the literature. Cells are color-coded according to the sign of the feedback gain estimated above in Table 2). Blue and red represent positive (excitatory) and negative (inhibitory) feedback gains, respectively. By definition, there is no excess of central delay for homonymous reflex loops (depicted in gray). White cells do not have a corresponding entry in Table 4.

The 13 major superficial muscles of the upper limb included in this study, with their associated abbreviations and maximum muscle force values from the literature, as well as our estimates of homonymous GTO feedback gains and afferent and efferent delays. Note that the GTO feedback gains are expressed in units of 10<sup>-3</sup> MVC/N (e.g., the gain for Delt Ant is 1.04·10<sup>-3</sup> MVC/N).

Gain precursor values. The gain precursor from the source muscle to the target muscle, denoted as , is assigned to the row and column of . Values of the same color are on the same scale and can be compared to each other. References are indicated in superscripted brackets. Superscripted Greek letters indicate that the value must be divided between muscle pairs. Entries along the diagonal represent homonymous feedback [25–48].
