Optimum Seating Comfort
To evaluate optimum seating comfort, you can apply the 7 universal principles of Alu Rehab. These seven principles are essential elements for a good sitting position. If even only one of these principles is ignored, potential problems are created for the user. So keep the following in mind:
1) STABILITY FOR THE PELVIS
- Together with the cushion, the basis of the seat unit must ensure the stability of the pelvis.
- Stabilisation on the sides and in front of the sitting bones (sitting problems) with a stabilising seat cushion.
- Stability can be improved with accessories such as comfort pads, abduction strap and abduction block.
2) PRESSURE DISTRIBUTION AND MICROCLIMATE
- Pressure distribution is achieved when the weight is distributed over a large as possible area. Without compromising stability.
- A breathable cover and a temperature-stabilizing material ensure a good microclimate, strengthening the skin and the resistance of the underlying tissue against external forces, to prevent pressure ulcers.
3) LUMBAR SUPPORT
- It is important that the back of the wheelchair provides enough space to the buttocks for proper lumbar support.
- Flexibility in height and depth is important due to the fact that the lumbar curve differs from person to person.
- The upper sacral bone (sacrum) must be supported. This is done by the shape of the cushion and the strap system in the velcro backrest.
4) SIDE SUPPORT
- Limited body stability requires a larger and more stable side support.
- A too large support, however, has an inhibitory effect on the user.
- The pelvis must be stable for the side support to have maximum effect.
5) FOOT SUPPORTS
- The height and positioning of the foot supports has a direct effect on the sitting position and pressure distribution.
- It is important that the foot supports are adjustable in order to ensure the stability of the upper body.
6) SUPPORT OF THE ARMS
- In the long run the muscles of the spinal column become tired. Optimally adapted armrests help the user to straighten up and maintain their sitting position and balance.
To sit in the same position for hours s very stressful for the body. It increases the risk for that the user collapses, and end up in a bad position.
The wheelchair must give the user the possibility to change position, and so relieve the muscle groups and distribute the pressure.
If the tilt function is used, a functional head support, of which the height, angle and depth is adjusted correctly, is important. This prevents inappropriate sitting positions.
The right choice of seating system and accessories prevent the user from sliding or falling forward over time.
