Figure 3

Box plots for Passive, Active and Reflexive parameters. Groups divided in healthy volunteers, chronic stroke patients with mAS = 0 and chronic patients with mAS ≥1. P_ROM: Range of motion passive, P_k: Stiffness in rest, P_RA: Rest angle. A_ROM: Range of motion active, A_MVC: Maximal voluntary contraction, A_CJT: Control over joint torque. R_ta: Threshold angle, R_lt: Reflexive loop time, R_kv: Reflexive contributions to joint resistance, R_{m_env}: Reflex modulation due to environmental changes. White bars: flexor (and R_kv in the lower right panel). Striped bars: extensor (and R_{m_env} in the lower right panel).
