Fig. 7

Patterns of muscle activation following visual perturbations. Description of muscle activation patterns arranged by 3-D rectangles representing groups of shoulder abductors (blue), posterior muscles (orange) and anterior muscles (green). Figures show average values (from all participants) of onset latency and duration of activation (“Activation period” axis), and activation magnitude (vertical axis). (Additional file 5: Table S3) details the values of EMG parameters triggered by visual perturbations. The overlapping rectangles depict left (L) and right (R) body sides. The letters indicate the shorter and longer onset latency, respectively. *: p-values observed within the factors characterizing the ANOVA statistical analysis (see text and Additional file 6 for more details)
