Case Control
N=36

Population: Age = 21-52 yrs; Gender: males = 20, females = 16.
Treatment: All were seated onto a pressure sensing transducer incorporated into an adjustable chair.  The output was calibrated so that eight pressure intervals were displayed.
Outcome Measures: Pressure distribution.

  1. Significantly reduced pressures were seen with greater thickness of lumbar supports (2.5-7.5 cm) for controls but not those with SCI (p<0.0001).
  2. The highest-pressure areas were greater for SCI group (p<0.05) than control group for all lumbar support conditions.
  3. The mean area of lowest pressure for all support conditions was significantly less for SCI groups than control group.
  4. SCI group had significantly lower pelvifemoral angles than control groups in all lumbar support conditions (p<0.05).
