Cushion Considerations: Providing the Required Postural Support

Cushion Considerations: Providing the Required Postural Support

This is the 3rd and final blog in our series on cushion considerations. Check out the 1st blog and 2nd blog. Check out our Wheelchair Seating and Positioning Guide for more information about wheelchair seating.


 

As we determine the appropriate method of pressure redistribution and cushion material, we must be aware of and consider how to address any postural abnormalities that may be present. Everyone is unique and has distinctive shapes and angles. Examples of asymmetrical postures at the pelvis include:

  • Pelvic tilt
  • Pelvic obliquity
  • Pelvic rotation

Asymmetrical Postures

When postural asymmetries are present, it can be a challenge to find the most appropriate cushion solution. We must determine the method of pressure distribution, the cushion material, and what shape of cushion will provide the postural support required while also determining how the abnormal posture will be accommodated for or corrected.

Shape

There are two primary geometries to cushions: Linear/Planar and Pre-Contoured.

Linear

A linear/planar cushion refers to a cushion that is flat when not loaded

Linear

Pre-Contoured

A pre-contoured cushion is made up of various geometric components which may include:

  • Lateral thigh support
  • Medial knee support
  • A pelvic well
  • Anti-Thrust or Wedge

Contoured


 

Accommodate or Correct?

When you have a client with an asymmetrical posture, an evaluation should be conducted to determine whether the posture is reducible or non-reducible, as this helps determine if the posture can be corrected or if it needs to be accommodated.

Reducible: means the posture can be adjusted to a better position, towards neutral alignment

Reducible Posture

Non-reducible: means the individual is stuck in the position and has the potential to get worse.

When a posture is reducible, a product should be selected that can correct the posture. For example, if a client has an obliquity or uneven pelvis, raising up the cushion on the low side of the pelvis can result in evening the pelvic position or “correcting” the posture.

When a posture in non-reducible, a product should be selected that can accommodate the posture and provide the most even pressure distribution possible. In the case of a non-reducible pelvic obliquity, raising up the cushion on the high side of the pelvis results in more contact with the cushion surface, accommodating for the obliquity and providing more even pressure distribution.


 

The ROHO® Hybrid Select cushion offers superior seating with hybrid positioning through a pre-contoured foam base. The pelvic loading area, gluteal ridge, and lateral thigh and medial knee support aid in alignment of the pelvis and lower extremities. The ROHO® overlay and IT insert with the ISOFLO® Memory Control provides the ability to correct or accommodate postural asymmetries of up to 1”. The client can be positioned to address their postural asymmetry, and the air can be locked into place (left side, right side, and IT pad) for postural alignment and added stability. The ISOFLO® memory control also allows for fine tuning of positioning based on an individual’s needs, on day one and as needs change over time.
