ErixFour® is a new shoulder orthosis based on our ErixThree® Neuro.
The new design combines thermoplastic reinforcements placed at selected points, a Boa® Fit System for individualized support, a magnetic buckle that makes application easier, and the new Neptune™ Sky material, which provides a cooling effect against the skin. ErixFour® has been developed as a more stable alternative for neurological patients with subluxation and anterior instability.

Thermoplastic Reinforcements
Integrated thermoplastic reinforcements over the scapula, humerus, and trapezius provide stable anchor points for the Boa® Fit System. Proxi® technology makes them moldable by hand.

Boa® Fit System
Provides lift and dynamic control of the shoulder joint. Consists of a main plate and three attachment points that can be positioned individually on the orthosis. Connected with a strong, low-profile Spectra® strap.

Neptune™ Sky
A new lining with improved moisture transport and cooling effect, featuring perforated CR foam for extra ventilation.

Friction Surfaces
Provide increased proprioception and biofeedback.

Magnetic Buckle
A specially developed, rotatable buckle that facilitates adjustment and application.

Compatibility
ErixFour® is compatible with the NRX® Strap, which can be used to stabilize and support the entire kinetic chain from shoulder to wrist.

Measurements
Measure the circumference around the biceps. The chest strap is adjustable.
