Abdominal belt for people with good anterolateral control during sitting. Sitting is the position where a patient maintains verticality by supporting his pelvis on the support base. It is made of a semi-rigid breathable three-layer material made of polyester, foam and polyamide. In addition, it has regulation and fastening straps with colour-coded buckles to improve positioning. Also included is a perineal strap that holds the person in the wheelchair and other resting places, such as chairs or armchairs. It can be used to allow adequate freedom of movement of the cervical and dorsal areas. This Orliman abdominal belt is indicated for patients with good sitting control but who slide out of the seat.
