Figure 2. Passive ankle joint kinematics.

Figure 2

(A) Dorsiflexion range of motion was inferior in both Middle Aged and Old animals compared to the Young group. Conversely, the linear region of (B) plantarflexion stiffness increased as animals aged. (C) There were no differences in plantarflexion range of motion across all groups, despite an increase in the linear region of (D) plantarflexion stiffness in Middle Aged animals. No differences in dorsiflexion or plantarflexion toe region stiffness were detected. n = 16/group. Data represented as means and error bars indicating standard deviation. Solid lines indicate significant differences (p < 0.05/3) and dashed lines indicate trends (p < 0.10).
