4.2 Alternative Function in Lock Mode
In Lock mode, the NEURO TRONIC system knee joint is a locked joint to
provide motion control. It is permanently mechanically locked in a determined
extension.
4.3 Alternative Function in Free Mode
In Free mode, the NEURO TRONIC system knee joint is an unlocked joint to
provide motion control. It is free moving up to a determined extension position.
When the patient is standing with the orthosis, the stance phase control is not
achieved mechanically but through the integrated posterior offset (fig. 5) and
the patient's remaining function of the hip and knee extension muscles.
4.4 Alternative Function in Permanent Unlocking
The NEURO TRONIC system knee joint can be permanently unlocked mechan-
ically with a lever, for example for activities such as driving a car or bicycle. In
this mode it is guaranteed that the system knee joint does not lock uninten-
tionally. To do so, unlock the system joint manually by setting the lever to F.
In order to save energy, you can then press the Lock button with the remote
control/User app. The system knee joint also remains unlocked if you select
another mode (e.g. Auto) with the remote control/app since the lever blocks the
locking pawl, which, therefore, cannot mesh into the toothing (fig. 6). In order
to change the system joint's mode as usual with the remote control/app, the
lever must be set to the dot (fig. 5).
