RIII-reflex modulation by contralateral stimulation. (a) The right RIII-reflex was facilitated by concurrent stimulation of the contralateral lower limb, regardless of attentional manipulation; main effect of intensity: F3,72 = 21.0, p < 0.001, ηp2 = 0.47; no main effect of attention: F1,24 = 0.2, p = 0.67, ηp2 = 0.01; no intensity-attention interaction: F3,72 = 0.3, p = 0.84, ηp2 = 0.01. Significant differences for pairwise comparisons for the main effect of intensity are indicated with symbols (***p < 0.001, compared with unilateral stimulation). White and black histogram bars represent different conditions, in which the focus of attention was on the right or left lower limb, respectively; (b). The right RIII-reflex was modulated by contralateral stimulation of the lower limb; main effect: F4,76 = 2.8, p < 0.03, ηp2 = 0.13. Significant differences for pairwise comparisons are indicated with symbols (**p < 0.01, compared with unilateral stimulation). (c) The right RIII-reflex was facilitated by concurrent stimulation of the contralateral upper limb; main effect: F3,48 = 4.0, p < 0.01; ηp2 = 0.18. Significant differences for pairwise comparisons are indicated with symbols (**p < 0.01, compared with unilateral stimulation). RLL, right lower limb; LLL, left lower limb; LUL, left upper limb; Error bars represent standard error of the mean.
