The Dynamic Rocker Back Interface (DRBi) is a Dynamic Back that moves in response to client force. The elastomers in this Dynamic Back then return the client to an upright position. Some Dynamic Seating components “lock-out” or “latch” to temporarily render the component static. When should the DRBi be locked out?
Our last blog discussed providing dynamic movement at the pelvis. Movement at the pelvis can be allowed anteriorly or posteriorly. If the pelvis moves posteriorly, the trunk will move posteriorly as well. So if posterior movement of the trunk is desired, dynamic seating components which allow posterior movement of the pelvis are provided, namely a dynamic back rest, which opens the seat to back angle in response to client movement and force. This movement may be utilized to protect back mounting hardware, absorb extensor forces and simply to provide active movement. If the client experiences a loss of trunk position upon return to upright, it is important to ensure that adequate lateral and anterior trunk support is used. Continue reading →
