I found this very interesting read on how the pelvis, hips, knees, feet , spine and neck are affected by posture in wheelchair and sitting equipment.....For those who are concerned about the effects of sitting for long periods and the effects on the joints then this is an excellent and very clear read.
It offers effects and practical solutions 
..an excellent read...!!
Regularly check the position of the pelvis so any changes can be quickly detected. Management will depend on whether the APT is fixed or correctable.
The following are possible solutions and either one, or a combination, may help.
Solutions:
1.A good quality, tension adjustable back
canvas with many narrow straps which
can be adjusted to encourage ‘softening’
of excessive lordosis. A standard back canvas
is inappropriate
2. Create a rearward sloping seat and carefully
set up the back angle to reduce the tendency
to lumbar lordosis
3.Using an adapted tray to form an anterior
support for the trunk is often very effective
and functional for the user
4.Padded pelvic positioning accessories
(i.e. belts, straps and harnesses) can be used
but need to be tight to be effective and are,
therefore, not always well tolerated
5. Open the hip angle by altering the seat angle
or using the recline function. Be careful not
to cause the pelvis to slide forwards
6. Tilt-in-space is very beneficial Modifications to posture and position are best
done in small incremental changes as these
allow the user to physiologically adapt to them
(these are just a few tips from the article..it seriously is a great read!)
