Custom Foam-in-Box System with Custom Rigid Pelvic Saddle

Happy Friday Everyone! I hope everyone had a great winter holiday. This has been a hectic week back. Lots of appointments and everyone getting back into the swing of things. I also have a UBC student with me for the next 5 weeks. She is the 3rd student I have taken in my career as an OT. I always enjoy having company on my visits and I think it is an honor to be able to show others what I do. OT is such a diverse career and I strongly recommend taking students no matter what field you are working in. Not only is the experience great for the student, but I also learn a lot about what’s new in the field and it keeps me on my toes when they ask me questions about why I make the clinical decisions I make. So, if you can, please take students! UBC has also made a blog as a resource for fieldwork educators. Click here if you would like to check it out!

Today, I thought I would share with you a custom foam-in-box seating system that was fabricated by Chad Kania at Ability Health Care. This client has many fixed joint deformities and is essentially fixed at 40 degrees of hip flexion. In order to function and drive a power wheelchair, this client needed to be positioned upright. For obvious reasons, keeping this client upright was difficult as there was very limited sitting surface available, which would result in a tendency to slide down on the system. In order to accommodate this, a custom rigid saddle was constructed.

One large moulding bag was used to capture the system as the client was quite petite. Trunk laterals as well as pelvic laterals were made from the mould to provide midline guidance. The pelvic saddle was then constructed by contouring the moulding bags under the client’s buttocks to ensure that enough sitting surface could be captured and made. The rigid pelvic bar with a front extension was then created with a mounting post that is secured at the bottom of the seat. The rigid pelvic bar/saddle was mounted at the bottom seat in order to create a rigid, almost continuous sitting surface from the front and back of the client’s pelvis.

This client has been very happy with the system and reports that they are quite comfortable and rarely slide downwards anymore. One issue that came up was the compression of the foam in the seat as all of the client’s weight is held by the saddle seat. The seat needed to be re-foamed and blake medical gel will be added for extra comfort and pressure relief.

I hope you enjoyed reading about this system. Hope you have a great weekend everyone!

Thanks for checking in today!

Seating is Super!
