6.4 Dynamic Adjustment
Adjustment of the hydraulic valves.
The user should experience the ankle moving smoothly with the body through the gait cycle
with no additional effort required by the user to overcome the hydraulic resistance of the ankle.
During this procedure the user should walk at normal speed, in a straight line on a level surface.
Guidance:
Following dynamic adjustment, trial the foot/ankle on ramps and stairs. Ensure the user is
comfortable with the kind of terrain he/she may normally be expected to encounter. If the user
reports any issues with comfort, usability or range of movement of the ankle, adjust accordingly.
