Fig. 4. Improvement in crouch does not correlate with spasticity or strength.

Fig. 4.

Mean reduction in crouch at midstance during exoskeleton walking plotted versus clinical measure of spasticity (modified Ashworth score; left) and body mass–normalized strength (MVIC, maximum voluntary isometric contraction; right) for the knee extensor (diamond) and knee flexor (circle) muscles. Pearson’s product-moment correlation analysis revealed no significant relationships between crouch reduction and spasticity (knee extensors, P = 0.77; knee flexors, P = 0.80) or strength (knee extensors, P = 0.41; knee flexors, P = 0.59).
