SeO, seat orthosis, anatomical seat cushion, custom made


Orthosis is composed by an anatomically shaped cushion with special provisions in the area of the trochanter for keeping an optimal pressure distribution between the seat and the body. Also special formatting for the upper part of the lower extremities and some provision for abduction of the legs may be incorporated.

Custom made moulded to the patient, eventually with casting or comparable techniques.

Different materials are used as inner material:
* elastic foam in a variance of stiffness
* gel mass
* water
* air
* combinations of materials
