RESNA Standards Committee on Wheelchair and Related Seating (WRS)
The RESNA Standards Committee on Wheelchair and Related Seating (WRS) will hold a virtual meeting on Wednesday, December 13, 2017 from noon to 1:00 pm Eastern Time to discuss the status of their work projects. The meeting is open to observers. Each standards committee is required to maintain a balance in membership. Anyone is welcome to join the committee, and we are especially looking for Consumers, Advocates, Caregivers. If you would like additional information, please contact the WRS Officers or Yvonne Meding.

These standards affect wheelchair users, caregivers and organizations representing the technical needs of persons with mobility impairments, Assistive Technology Practitioners and Assistive Technology Suppliers of Wheelchairs and Seating Devices, the Food and Drug Administration that manages wheelchairs as medical devices, the Centers for Medicare & Medicaid Services (CMS) and Medicare Pricing, Data Analysis and Coding (PDAC) who establish coding guidelines and establish policy for the provision of mobility technologies, manufacturers of wheelchairs, scooters and seating devices, and researchers, designers and test laboratories of wheelchair seating devices.
RESNA WC-3 Wheelchairs Volume 3: Wheelchair Seating
This standard covers wheelchair seating devices that are intended to provide postural support and/or tissue integrity management. It specifies test methods or methods of measurement for: vocabulary; the physical and mechanical characteristics; and static, impact and load strength testing. This standard is useful for manufacturers and suppliers of wheelchair seating devices that are intended to provide postural support and/or tissue integrity management who wish to provide consistent, quality information to clinicians and consumers about their products. The standard includes the following sections:
- Section 1: Vocabulary, reference axis convention and measures for body posture and postural support surfaces
Section 1 applies to seating intended to provide postural support within a wheelchair. It specifies a global coordinate system that permits the determination and recording of a person's posture while seated in a wheelchair, and standard terms and definitions for use in describing posture and the dimensions, location and orientation of seating support surfaces.
- Section 2: Determination of physical and mechanical characteristics of devices intended to manage tissue integrity Seat cushions
Section 2 specifies apparatus, test methods and disclosure requirements for wheelchair seat cushions intended to maintain tissue integrity and prevent tissue trauma.
- Section 3: Postural support devices Test methods for static, impact and repeated load strength
Section 3 specifies test methods for the determination of static, impact, and repetitive load strengths as well as disclosure requirements for postural support devices intended for use with wheelchairs.
