Figure 3. Neuromuscular outcome measures.

Figure 3.

Individual (color-coded circles) and group mean (bars) pre- and post-exo-therapy neuromuscular variables, including a) co-contraction index (CCI) between the soleus and tibialis anterior; b) the relationship of the experimental soleus activation profile to a typical activation profile at a non-dimensional speed of 0.25; c) variance in muscle activity of the soleus, tibialis anterior, vastus lateralis, and semitendinosus that could be explained by one muscle synergy (VAF1). ‘Typical’ values were calculated using a publicly available dataset [30] of individuals walking at a non-dimensional speed of 0.25.
