Long-Term Care

Chair and wheelchair positioning

LTC Nursing Assistant Trainer, November 17, 2011

The body works best when it is in good alignment. Pain is decreased and the risk of injury is reduced when the resident is properly positioned. When a resident is seated in a chair or wheelchair, pressure on the skin is affected by:

  • Postural alignment
  • Weight distribution and stability
  • Balance
  • Pressure redistribution (the ability to distribute a load over a surface, which causes a shift in pressure from one area to another) or pressure relief (the complete reduction of interface pressure below capillary closure pressure)

When the resident is properly positioned, he or she should end up in the 90-90-90 position. This means that the feet and ankles are at a 90 degree angle to the lower legs, the lower legs are at a 90 degree angle to the thighs, and the hips are at a 90 degree angle to the torso.

This is an excerpt from the HCPro book, The Long-Term Care Nursing Desk Reference, Second Edition, by Barbara Acello, MS, RN.
