Common input strength (CIS) index. A and B: CIS distributions for FPL-FDP2 (—) and FPL-FDP3 (- - -) in the 2- and 5-digit grips, respectively, computed on all motor-unit pairs from all subjects. For graphical purposes, CIS data were binned into 0.1 intervals. Gaps in the distributions indicate no motor-unit pairs with that CIS value. C: mean ± SE of CIS values computed across subjects for each grip type and muscle pair (*, P < 0.05; main effect of muscle pair on CIS, ANOVA with repeated measures).
