Fig. 15 Fixing Procedure of the Cushion Valve
1
As shown in Fig. 15, turn the cushion valve with a hex wrench (2 mm).
Clockwise: Cushion effect is enhanced and impact is reduced.
Counterclockwise: Cushion effect is weakened and impact is increased.
2
Let the amputee walk slowly by securing safety with parallel bars and
confirm that the knee extends fully.
If the knee does not fully extend, turn the cushion valve to the left to
weaken cushion effect.
3
Let the amputee gradually increase his or her cadence. Confirming sound
level of terminal impact, select an appropriate valve position.
