From: Abnormal coactivation of knee and ankle extensors is related to changes in heteronymous spinal pathways after stroke

Figure 3

Group comparisons of the coactivation of ankle extensors during the knee extension task in 13 stroke and 10 healthy participants. Mean levels of coactivation of soleus (A) and gastrocnemius lateralis (B) (expressed as a % of their maximal EMG) during the maximal activation of vastus lateralis (at VL max) and rectus femoris (at RF max) for the knee extension task. Vertical bars = 1 SEM. Asterisks represent significant differences between the stroke group (black bars) and the control group (white bars) (* p ≤ 0.05; ** p ≤ 0.01).
