Promote Lumbar Lordosis
Standing
Posture - Lordotic the lumbar protion is curved inward
Sitting
Posture - Kyphotic, which results in increased pressure on the discs
located between
the vertebrae of the spine.
How?
1. Lumbar
Support
The
lumbar support does not have to perfectly match the inward arch of the
lower back.
A 2-inch
thick lumbar support can maintain lumbar lordosis with a seat backrest
angle of 90¢X.
The
lumbar spine resembles closely the lumbar curve of standing posture when
the backrest angle was reclined ton110¢X and the lumbar support is used.
2.
Forward-tilting Seat
It opens
the angle between the hip and upper torso, thus producing a more relaxed
posture.
Most
relaxed posture - 135¢X (sleeping and weightless environment)
