Back support and the PSIS

A good back support makes it possible to optimize pelvic alignment and then balance the trunk without affecting pelvic alignment. The key to achieving this support goal is in the way the back support pivots around its axis for seat to back angle.

The Ride Java Back Support, front view (shown with Java Cushion).

When the Java Back is positioned correctly on the wheelchair, it provides optimal pelvic alignment. It can then be adjusted for trunk balance without changing the pelvic alignment already achieved. Correct height adjustment of the Java Back on the wheelchair is key. 

When determining the correct height of the Java Back on the client’s wheelchair, it is important to locate the client’s PSIS (Posterior Superior Iliac Spine).

Line up the PSIS (indicated by dotted line) at pivot point of the Java Back, shown here from rear.

The PSIS is the most prominent posterior aspect of the iliac crest. If you’re not sure how to locate a client’s PSIS, here are some tips: 

  1. Stand behind the client and find the iliac crest laterally. Move your thumbs in and down until you find a prominent bony bump (which sharply disappears distally and inferiorly).
  2. Look for the two dimples on the lower back — the PSIS are typically located under the dimples.

Then adjust the back height so that the back angle pivot point lines up with the client’s PSIS. This allows the back to pivot around that point of control at the pelvis and not affect the anterior-posterior (sagittal plain) pelvic  orientation.  

New clinical research from Germany

The Forward and Java Cushions were the subject of recent clinical trials, to evaluate their efficacy, in support of Ride’s entry into the German market.

Going, going…

Recently, Ride introduced a new, ultra-breathable 3D mesh liner option for the Ride Custom Back. It has quickly become evident that this new liner is superior in every way to our original composite (Brock®) foam liner.  It keeps the sitter even cooler and drier, is easier to clean, and in-field modifications are much more efficient. 

In alignment with our mission to use only the very best materials to make Ride cushions and back supports, we will discontinue offering Brock foam on the Ride Custom Back as of May 31, 2021.

Orders for the Ride Custom Back with Brock liner received by the end of business on May 31, 2021 will be fulfilled.  Quotes for the Ride Custom Back with Brock foam liner that are open as of June 1, 2021 will be modified — the Brock foam option will be replaced with the ultra-breathable 3D mesh liner option.  

Q&A

Is there an extra charge for the ultra-breathable 3D mesh liner option?

A: No.

Q: Is the ultra-breathable 3D mesh liner heavier than the Brock foam?

A: No, the mesh liner does not add any additional weight to the Ride Custom Back.

Q: How thick is the ultra-breathable 3D mesh liner?

A: 7mm thick. The liner will be wrapped around the edges of the back. There will be no perceptible difference in the back, from the standpoint of the end user, between the original Brock and the new ultra-breathable 3D mesh liner.

Q: Are there other liner options for the Ride Custom Back?

Ride Custom Back with soft foam insert

A: Yes, another option is the AccuSoft open-cell polyurethane foam liner which is a slightly thicker, more forgiving option.  An incontinence-proof cover can be ordered for the AccuSoft liner in place of the breathable spacer fabric cover.

Q. Can I order an incontinence-proof cover as a replacement for the spacer fabric cover with the ultra-breathable 3D mesh liner?

A. No, the ultra-breathable 3D mesh liner requires use of the spacer fabric cover, however an additional incontinence-proof cover can be ordered to go on top of the spacer fabric cover if needed.

Q. Is the commode back available with the ultra-breathable 3D mesh liner?

A. Yes.

Q. Is Soft Fit available with the ultra-breathable 3D mesh liner?

A. Yes.

Q. Is Enhanced Relief available with the ultra-breathable 3D mesh liner?

A. Yes.

Q. Are Axillary Pads available with the ultra-breathable 3D mesh liner?

A. Yes.

Q. I used to carve away Brock foam when relief in certain areas was needed. How should I handled these modifications with the ultra-breathable 3D mesh liner?

A. Simply cut out the liner in the areas where relief is needed using a sharp razor knife. Then, pull the cover back over the liner. Done!

Lateral reinforcement option for Ride Custom AccuSoft Cushion

Are you familiar with the Ride Custom AccuSoft™ Cushion?  Like the firmer Custom 2 Cushion, the AccuSoft is carved to precisely match the client’s shape for superior postural control, improved mobility, and skin protection. 

While Ride continues to believe in the benefits of a firm, orthotic mode of support, the AccuSoft Cushion is the result of understanding that there are times when a softer cushion material may be what’s needed. It’s made of soft, open-cell polyurethane foam to create a supple sitting surface.

In cases where additional rigidity is needed to support the lateral thighs, Ride now offers a lateral reinforcement option. Quite different from traditional, industry-standard metal or composite reinforcements, this innovation boosts structural integrity, while using forgiving materials that help reduce the risk of injury to skin and soft tissue.    

Reinforced lateral thigh support option for Ride Custom AccuSoft Cushion.

When the reinforced lateral thigh support option is ordered, ½” of cushion foam will be removed from each lateral thigh support, and the reinforcement material will replace the foam that was removed — without increasing the overall width of the cushion. 

If even greater lateral thigh support and control is necessary, we encourage you to consider the Ride Custom 2 Cushion, or contact us to discuss your options.

If you’re utilizing the new bundled pricing option, the reinforced lateral option is included in the AccuSoft Cushion bundled price.
