Following post hoc testing, the magnitude of mean
difference between the maximum and minimum pressure
factor mean within each of the independent variables
were examined by gender. The mean pressure factor
difference between male and female results was 0.88. For
males the chair factor appears to have resulted in
the greatest difference between the lowest and highest
values (difference ¼ 2.12), followed by participant effects
(difference ¼ 1.24), angle (difference ¼ 0.48), and finally
armrest usage (difference ¼ 0.22). Female results were
similar, with chairs having the greatest impact on
pressure factor values (difference ¼ 2.14), with participant
differences next (difference ¼ 1.59), and finally angle
(difference ¼ 0.86).
