Consistency and attenuation of periodic reflex modulation patterns: patterns found in 1 or both muscle groups of a pair with antagonistic relation (A) and bilaterally (B). The consistency of a pattern, measured within each muscle, is significantly larger, and the attenuation of the smaller responses relative to the larger ones significantly stronger when the periodic reflex modulation is concomitantly occurring in the related muscle (bars are mean values across all available data sets, error bars are SE; all P < 0.00001).
