Relationships between MAS scores and reference MCP joint stiffness [15,17,18,20].

Subject Condition	Stiffness Level	MAS Score	MCP Reference $\mathbf{Stiffness}\mathbf{(}\mathbf{N}\mathbf{m}/\mathbf{r}\mathbf{a}\mathbf{d}\mathbf{)}$
Healthy	Low Stiffness	0	≤0.04
Slight spasticity	Medium Stiffness	1+	$\left(0.04,0.5\right)$
Moderate-to-severe spasticity	High Stiffness	≥2	≥0.5
