Complex Rehab Technology Products Flashcards

Which professional credential specifically demonstrates competency in assistive technology evaluation and recommendation, and is often required for CRT evaluations?

Answer: ATP (Assistive Technology Professional) from RESNA

The ATP credential from RESNA (Rehabilitation Engineering and Assistive Technology Society of North America) is the recognized standard for assistive technology competency, including CRT evaluation.

A pediatric client using a manual wheelchair is growing rapidly. Which wheelchair feature BEST accommodates growth without requiring full replacement?

Answer: Adjustable-width seat frame with adjustable axle position and seat depth

Adjustable-width and depth seat frames with repositionable axles allow the chair to grow with the child, maximizing the useful life of the equipment.

What is the purpose of a 'pressure mapping' assessment in a complex seating evaluation?

Answer: To visualize interface pressure distribution between the client and seating surface to prevent pressure injuries

Pressure mapping uses a sensor mat to display real-time pressure distribution, identifying high-pressure areas at risk for tissue injury and guiding cushion selection or modification.

A client with spastic cerebral palsy exhibits a strong extensor thrust while seated. Which intervention is MOST appropriate to counteract this pattern?

Answer: Use a hip belt angled at 45 degrees and an anterior knee block to interrupt the extensor pattern

A 45-degree hip belt secures the pelvis, and an anterior knee block or padded knee separator interrupts the extensor thrust by preventing full leg extension during spasm.

Under the HCPCS classification system, what distinguishes a 'custom-fabricated' seating system from a 'prefabricated' one for billing purposes?

Answer: Custom-fabricated systems are made from scratch for a specific individual using measurements or a mold; prefabricated systems are mass-manufactured and fitted

Custom-fabricated seating is constructed for a specific individual using direct measurements or a body cast, while prefabricated seating is manufactured in standard sizes and selected/adjusted to fit.

A power wheelchair user who relies on a ventilator needs to transport the ventilator on the chair. What mounting consideration is MOST critical from a safety standpoint?

Answer: The mount must be positioned to maintain the chair's center of gravity and secure the device per manufacturer specifications

Medical device mounts must be engineered to maintain the wheelchair's stability (center of gravity) and must secure the device according to both the chair and ventilator manufacturer's specifications to ensure safe transport.

Which statement BEST describes the role of the CRT supplier in an interdisciplinary seating team?

Answer: The supplier provides product expertise, performs fitting and delivery, and ensures the prescribed equipment meets the clinical team's goals

The CRT supplier contributes product knowledge, equipment configuration, delivery, follow-up, and funding navigation as a collaborative team member alongside clinicians, the client, and caregivers.
