Etac Prio 3D multi-functional wheelchair

We are proud to present our new 3D back support system! A patented innovation that is mouldable in all directions, ideal for asymmetry and kyphosis.

Kyphosis affects the whole body

Aging affects the curvature of the spine. If the spinal curvature exceeds 45°, it is diagnosed as kyphosis. We have created a back support providing space and support in all directions for users with kyphosis and other asymmetries.

Managing to be active

Sitting in a slouched position affects the ability to be active. The head moves forward and drops, which also displaces the centre of gravity. The curved shape of the upper trunk limits the mobility of the shoulder blades, affecting the mobility of the arms. A kyphosis accelerates these symptoms. A lot of energy is used to hold the head up. The sitting position becomes unstable and the degree of activity is limited. The goal is to improve the head position and create a supportive and relaxed position, from the pelvic area to the upper trunk. This will also facilitate activity.

Time to shape up!

3-part back cushion

3-part back cushion

The soft, padded side panels provide lateral support and creates a horizontal contoured shape. The centre panel follows the vertical shape of the kyphosis.

Back support height

Back support height

A kyphotic back often requires a lower back height. The Prio 3D back support can be adjusted from 45 to 60 cm.

Traditional head support

Traditional head support

The head can be positioned in front of the trunk. This puts demands on the depth adjustment of the head support.

Dynamic pelvic support

Dynamic pelvic support

The users´s back must be supported from the pelvic area and up. The dynamic pelvic support is just as important for a user with a kyphotic back since it enables pelvic and spinal variations.
