IDH2 and stroke disorder: When the stroke dynamics were turned on, the maximum posterior force increased (NDH4 vs. IDH1 Early; P = 0.014) and there was a small decrease across the IDH trials (RM ANOVA: F[4, 60] = 3.201, P = 0.019; pairwise comparison for IDH1 Early had greater posterior force than NDH4: P = 0.043).
