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?
Dynamic Seating is often used to prevent equipment breakage, specifically the wheelchair frame and seating system. The Dynamic components absorb strong, repeated, sudden, and/or sustained forces, hence protecting vulnerable areas of the seating and mobility base. This was addressed in two prior Blogs (Dynamic Seating to Prevent Equipment Breakage, part 1 and part 2). But what about the Dynamic Components themselves? Just how durable are these?
Our last blog addressed using dynamic seating to prevent equipment breakage, particularly with clients who exhibit increased muscle tone. These clients often display strong extension, sometimes referred to as an “extensor thrust.” This intermittent and strong force can lead to breakage of the wheelchair seating system and frame.

Dynamic Seating is often used to prevent equipment breakage. Some clients who use wheelchair seating exhibit increased muscle tone. This is common in clients with diagnoses such as cerebral palsy, traumatic brain injury and Huntington’s disease. Increased muscle tone or spasticity is caused by an imbalance of signals from the central nervous system to the muscles. In addition to increased muscle tone, primitive reflexes and involuntary movements may also be present. Continue reading →
