by using a knob on the top side of the orthosis (identical to the unlocking in the STABIL)

Swing phase

During the swing phase, the knee hinge is not locked, so a natural knee flexion is possible. At the end of the swing phase the leg reaches the

extended position again and the knee automatically falls into lock.

OPERATION OF THE STABIL

The knee hinge of the UTX-STABIL orthosis is kept locked by a ratchet. This ratchet locks the knee joint during stance and walking, but can

be unlocked manually before sitting down. For this unlocking, a push-button is mounted at the top of the UTX-STABIL orthosis.

By pushing in the button, the hinge is unlocked, but only when the knee is stretched. When the knee is not extended, unlocking is potentially

unsafe. In that situatie pusing the button therefore has no effect. So the user has complete control over sitting down safely. The ankle hinge

of the UTX-STABIL and SWING orthosis compensate for any flaccid foot drop by means of a built-in spring. The foot is thereby returned to

the neutral position in the swing phase.

On request, alternative release latches are also possible, such as a lever on the knee hinge, or a lever situated on the leg at the upper pelotte

carrier.

No lock against flexion, but still blocking hyperextension. (The UTX-FREE can optionally be extended with an FS and DZ as well as POST

and in ESF).

Pelotte carrier just below the knee positioned at the back (posteriorly) provides additional control in case of hyperextension. A thus placed

pelotte carrier immediately captures the force of the backwards bending knee.

Cable provides stability to frame, thereby generating control over valgus (UTX lateral, cable medial) or varus (UTX medial, cable lateral).

Only lateral ankle hinge. In the ankle hinge of the UTX is a spring that helps to lift a flaccid foot drop during swing phase.

Two hinges. Medially and laterally. Thus, greater control in the frontal plane for valgus and varus ankles.

The UTX ESF has two versions for stability around the knee in the sagittal plane: FREE (no flexion stop, but lock agains hyperextension) or

STABIL (fully locked but, manual release). In case there is a passive or spastic foot drop, the integrated AFO of the orthosis will generate the

required control. The AFO will give stability, for a foot drop or prevent equinus foot position.

As ESF, but now with UTX frame in SWING embodiment.

Locking

During stand and during stance phase of walking the knee hinge of the UTX-SWING is locked.

The knee hinge is released at the end of the stance phase. The knee can move freely during the swing phase. At the end of the swing phase,

the hinge falls back into it's lock for the next stand phase. This happens automatically when the knee is sufficiently stretched. The extended

position does not necessarily have to correspond with a knee angle of 0°. The locking position depends on the personal alignment of the

UTX-SWING.
