A positioning device, such as a pelvic positioning belt, is designed to maintain alignment with the support surfaces (i.e. the seat and back), provide stability and postural support and to promote function. A restraint is intended to limit movement to protect the client and/or others.
Carrying any heavy object on the back or looped around the back canes will adversely affect the DRBi function and is not recommended.
For some clients, knowing that movement is possible is enough to decrease the amount of resistance applied to the seating surfaces. As active extension is diffused, it may not persist when using dynamic components.
