Frequently Asked Questions
When adding support to PSIS, is it the backrest or in the cushion? As in, how do we do this in product?
Yes, the support is added to the posterior lateral pelvis so is added to the backrest. Its role is to influence the pelvis to become or maintain a neutral position.
How to assess anterior pelvic tilt on the plinth? During sitting simulation?
Yes, this is probably the easiest place to try and reduce an anterior tilt; it's difficult to do in supine.
How do you document your findings? It is so much about 'feeling' the changes. I have used someone taking photos in the past of when a position feels positing that I want to mimic, but once you start juggling measuring tapes or goniometers during a MAT assessment I often feel I lose the 'feel.'
Taking photos is a great way to document. I also have an assessment form with images and tick boxes that makes it easy and quick to jot findings down. Find an assessment form that allows you to quickly get the info down (with one hand!). Education in Motion has created an assessment form which you can find here.
At one point, I thought Amy mentioned that for a fixed pelvic obliquity, correcting under the high side? I currently correct under the low side. Is there a time that you correct under the high side and why?
For a reducible obliquity, I will try to build up under the low side. For a non-reducible obliquity, I will build up under the high side. This is to promote pressure distribution throughout both sides of the legs, thereby reducing peak pressures.
Is there an easy way to identify a client's PSIS? A certain landmark? I find this hard to find.
This one is tricky - generally it's right below the dimples. If it's hard to find, use the other landmarks, such as iliac crest.
