Table 4 Model 2 marginal means for factors Ext2 and Flx2 on pendulum test metrics (RI = relaxation index, ERI = extension relaxation index, F1amp = 1st flexion amplitude, E1amp = 1st extension amplitude, Plat = plateau angle, and Ncyc = number of oscillation cycles)

From: Predictive value of the pendulum test for assessing knee extensor spasticity

MODEL 2

Flx2: Flexor spasticity

Low spasticity (MAS = [1,1+])
