Make Good Sitting Posture Easy.

People who are injured have trouble keeping a good sitting posture.

Good ergonomics makes good sitting posture easy by putting the body’s strongest muscles in the best position to keep the torso upright, so the postural muscles can work gently and move more often

Leg strength is critical to maintain movement and balance for the torso

The balance point for the upright spine is at the base of the spine, or the bottom of the pelvis on the chair, and the chair height is the foundation for the best leg strength to support the body

Sustaining the best posture requires first 

• Getting both torso support and mobility from the chair
• Then finding arm support on the work surface

The spine can relax into slumping when the postural muscles work too long out of their best position.

The next slides will show how posture can change when the workstation does not fit the way the body does the work.
