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.

Java Back’s little buddy: the fully-adjustable Java Decaf Back

Decaf_Java_Back_from_rear

A properly selected and fitted back support can help a wheelchair user maintain their balance and best position on their cushion, resulting in the stability needed for increased freedom of movement and independence.

Accurate support of the trunk can also help reduce the stresses of pressure and shear on the cushion, contributing to good skin outcomes.

Shown here, designed specifically for pediatric users (or very narrow adults), the Java Decaf Back’s patented bio-mechanical design provides the flexibility to accurately fit both the trunk and pelvis for support, comfort and enhanced mobility. The Decaf Back fits any wheelchair 10-14″ in width. The highly adjustable hardware and personalized contour at the pelvis help to provide balanced support and freedom of movement.

Precisely formed: Custom Backs

Ride Custom Back forming process

Ever wonder how the Ride Custom Back is made? Check out this video…

Hot, high-grade prosthetic plastic is vacuum-formed to a specific client’s back shape. The shell provides stability and is the outermost layer that hardware will mount to. Once the shell cools, Ride technicians will cut the back out and begin adding the materials necessary for breathability and comfort. It’s just one part of the process involved in delivering the best custom products available to wheelchair seating users.
