4 Working instructions for electronic components

4.1 Control electronics

The electronic control unit measures the position of the orthosis during the gait cycle and unlocks the joint prior to
toe-off. Prior to heel strike at the end of the swing phase, the orthosis knee joint is locked in the extended position
so the patient can step down safely. In order to determine the optimum joint activation point for the patient, the
electronics are equipped with an auto-calibration feature. This feature must be activated by the orthopaedic techni­
cian during the initial patient fitting. Test mode, which provides acoustic feedback for joint activity while walking, is
useful for the technician in order to establish the settings.
Two switching options are available to the patient. The patient activates / deactivates the sitting and locking func­
tion with two separate buttons.
