The alleviation pressure (AP) cushion is a dynamic
cushion system with
three bladders at the pelvic region. The bladders can be
deflated and inflated
in a certain sequence to relieve the pressure on the
ischial tuberosiites (IT) and coccyx/sacrum. The
design of the foam
base, bladder and
pneumatic and electronic system
of the AP cushion
is discussed in this
paper. And testing
is conducted to verify
the effectiveness of
the AP cushion.

Interface pressure mapping (IPM) has long been a useful assessment tool to augment the seating evaluation. Technological improvements in both hardware and software have made steady advances across manufacturers. Likewise, progress has been made in the scientific study of the clinical application of pressure mapping. This course will focus on the science behind IPM and recent research findings which influence clinical interpretation of the map. Phenomena such as creep, the effect of the mat and the influence of cushion materials will be highlighted. Additionally, reliability of specific metrics will be discussed, with a de-emphasis on the use of single sensel peak pressure values. Emphasis will be placed on the importance of using a consistent IPM protocol within your seating clinic to make relative cushion comparisons.
