Table.

Average angular range, duration, and angular velocity of trailing (left) limb during controlled lowering phase of descent at two variable impedance knee mechanism (VIKM) duty cycle levels. Number in parentheses is one standard deviation.

Damper Duty Cycle (%)	Average VIKM Torque Output (Nm)*	Angle Range (°)	Controlled Lowering Duration (s)	Mean Angular Velocity (°/s)	Peak Angular Velocity (°/s)
51.2	47	89.60 (1.30)	1.01 (0.14)	90.0 (11.7)	186.7 (6.7)
39.2	38	89.75 (3.08)	0.77 (0.09)	117.6 (12.9)	229.2 (20.5)
