The Science of Dynamic
Movement
Ask yourself why office workers don’t use
cafeteria chairs at their desks. It’s because
seat designers applied the science of
ergonomics to the office seating
community years ago.
Rigid seating is more than just
“uncomfortable.” We know that a healthy
spine requires movement. Adjustability and
back flex are fundamental seated posture
requirements for the human body.
Unfortunately, these elementary features
have not found their way into most
industrial vehicle seats in the marketplace
today.
Although some suspension seats do
provide up-and-down movement, vertical
displacement becomes a concern and the
rearward flex critical to a healthy back is
missing.
[And so is the comfort.]

DYNAMIC MOVEMENT
Moving is essential for our well-being. Researchers have long known the negative consequences of
rigid sitting. It is commonly recognized that constrained postures can lead to a broad range of chronic
disorders. These include joint impairments, inflamed tendons, chronic joint degenerations, and
muscle pain.
Sitting in a static position increases localized pressure on the body and interrupts blood flow in
direct proportion to the loads acting on the muscles. Scientific literature on musculo-skeletal
disorders makes it clear that prolonged invariable postures are uncomfortable and can lead to
serious disorders.
After the age of 10, our spine loses its ability to actively nourish the intervetebral discs and eliminate
waste products. After this age, the spine receives nutrients and eliminates waste through passive
changes in osmosis that are induced by movement.
THE BOTTOM LINE
Evidence points to the fact that prolonged static sitting compromises spinal structures by reducing
disc nutrition, restricting capillary blood flow, and increasing muscle fatigue. When we sit down our
hamstrings flex, causing the pelvis to rotate back. This excessively flattens the lumbar curve. It also
tilts the angle of the individual vertebrae so that pressures at the front of the discs increase.
It is commonly believed that rigid sitting postures, which flatten the lumbar spine, actually amplify
vibration transmission. It has been proven that intermittent reclining is important and beneficial. This
type of movement simultaneously reduces loads on the spine and supporting muscles, helping to
reinstate the lumbar curve as the weight of the torso shifts back against the backrest and the angle
between the torso and legs increases.
"There is no 'best' position. The best solution is to keep moving!"
