The hip positioner on a Pacer or a TRAM does the alignment work, and this pad is what makes it tolerable to sit against for any length of time.
It cushions the contact point at the hips, so the client gets the benefit of controlled pelvic position without a hard edge pressing into them during gait training or a transfer. Comfort at that contact point is not a luxury. A client who braces away from a hard positioner loses the alignment you set it up for, and sessions get shorter.
It fits the small hip positioner and is a straightforward replacement item when the original pad has been through enough cleaning cycles, which in a shared school or clinic device happens sooner than anyone expects.
