Figure 4

Group comparisons of peak activation latencies for vastus lateralis, rectus femoris, gastrocnemius lateralis and soleus during gait in 13 stroke and 10 healthy participants. Peak activation latencies for vastus lateralis (VL), rectus femoris (RF), gastrocnemius lateralis (GL) and soleus (Sol) during the stance phase of gait are expressed as a percentage of the gait cycle. Mean peak activation latencies are presented for the paretic (black bars) and non-paretic (grey bars) sides of stroke participants and control participants (white bars). Vertical bars =1 SEM. Asterisks represent significant differences between groups (* p ≤0.05).
