Dynasit
Dynamic sitting to prevent pressure ulcers.

Subjects who use a wheelchair for their mobility often adopt a passive sitting posture in their wheelchair. This might result in physical problems like pressure ulcers. Variations in sitting posture decrease the load on vulnerable areas and can therefore minimize the risk of pressure ulcers. Subjects without mobility problems continuously change their sitting posture in a dynamic way. Dynamic sitting can be used to prevent pressure ulcers in subjects with impaired sensory and motor functions that use a wheelchair for their mobility.

In the Dynasit project an experimental seating device has been developed, capable of imposing dynamic sitting behavior. The device is fully individual adjustable and uses a mechanical concept to adjust the global posture. In addition it contains a system to control and manipulate the load on the seating surface by means of actuators in the seat. Goal of the Dynasit projects is to analyze if dynamic sitting behavior can be imposed with the experimental sitting device and to investigate the effects of this sitting behavior on the seating load. Seating load is evaluated by means of force sensors in the seat, interface pressure mapping and the measurement of tissue perfusion and oxygenation with the O2C (Oxygen to See, LEA Medizintechnik, Giessen Germany).

Projectpartners of the Dynasit project are: Roessingh Research and Development, University Twente (BMTI), Demcon, PR-Sella, Welzorg orthopedie.
