• Red: extra firm.
Note: Before installing the Extension Assist, try reducing the swing
extension resistance by turning Valve "E" (Fig. 8: E) to the left to facilitate
full knee extension.
Installation of the Extension Assist (Fig. 9)
1. Remove the Bumper Cover (A), Bumper (B), and Shims (C).
2. Install the Spring Cup (D) into the Hole (E) inside the Distal Tube
Connector.
3. Firmly seat the Spring Cup by gently tapping it with a rubber mallet
(or a similar hand tool).
4. Place the Ferrule (F) over the Cable (G).
5. Place the Spring (H) over the Cable and Ferrule (try the yellow spring
first).
6. Insert the Cable and Spring into the Spring Cup, with the ball end of
the Cable first.
7. Slide ball end of the Cable through the Hole (E) in the Tube
Connector and insert the ball into the Slot on the device's Bottom
Link (I) by using needle-nose pliers or a small screwdriver.
8. Re-install the selected Shims, Bumper, and Bumper Cover.
9. Let the patient walk and adjust the swing extension resistance with
Valve "E" (Fig. 8: E). If sufficient extension is not obtained with a fully
open Valve "E", try a stiffer spring.
10. Readjust the swing flexion resistance after installing the Extension
Assist unit with Valves "F" and "H" (Fig. 8: F, H).
Follow-up check
• Reassess adjustments after a couple of weeks.
• It may be necessary to change the Shim and Bumper adjustments
after the patient has gained some experience with the device.
• Over time, the patient's increased device experience, confidence
during use, and proficiency may warrant a change to a firmer Bumper
and/or an increase in Shim thickness.
