Dynamic seating allows specific parts of the seating system to move in response to forces generated by the wheelchair user. By absorbing and diffusing these forces, dynamic components can reduce the leverage that may otherwise move the client out of alignment. The components are designed to help guide the client back toward their starting position after movement.

When a wheelchair user extends at the hips, knees, or neck against a static seating system, the force has nowhere to go. The client may leverage against the footplates, back support, or head support and move away from the desired position. Hip extension, for example, may elevate or push the pelvis forward and contribute to a posterior pelvic tilt.

Dynamic seating may be appropriate for some clients with dystonia or other large, forceful movements. These movements can occur in multiple planes and make it difficult to maintain alignment with the seating support surfaces. Dynamic components can accommodate some of this movement while absorbing forces and reducing leverage within the seating system.

No. Dynamic seating may be used together with traditional positioning strategies when clinically appropriate. Pelvic belts, appropriately configured cushions, back supports, and other positioning components may continue to provide necessary support while dynamic components allow controlled movement and diffuse forces.

For appropriate clients, dynamic seating may reduce the frequency of repositioning by allowing movement without the same degree of loss of alignment. Because forces are absorbed and leverage is reduced, the client may be better able to return to their starting position after extending or making forceful movements.
