The SwingChair Science – How to Relieve Back Pain caused by Sitting

SwingChair is the application of Kinesiology, the science of human motion, to Ergonomics, the study of how people work. SwingChair improves health, wellness and productivity by putting back into the office the single most important component to a healthy back: motion. SwingChairs relieve the stress and strain common to fixed posture chairs by enabling the same gentle, guided motion used by healthcare providers to rehabilitate injuries.

Despite the increased use of ergonomic chairs in offices and at home over the years, the rate of back injuries and issues has continued to grow. Healthcare providers who specialize in back care such as orthopedic surgeons and chiropractors in efforts to stem the growth in injury, expanded their search for a solution to include Kinesiology (the scientific study of human movement), occupational and physical therapy, and modern imaging tools such as the Positional MRI.

These advanced studies began to show how injuries occur to people who are simply sitting down to get their jobs done. What they discovered is that there is no such thing as a safe, neutral posture for seated workers.  They found that unless your body is able to move freely from one posture to the next while you do your work, given enough time fatigue, pain and possible long-term injury may occur.

The solution…SwingChair! With SwingChair, when you move, the seat and backrest perfectly counterbalance that motion. The result is an amazing reduction in stress across your entire body. The same freedom you feel when you walk, swim or dance is what you feel in a SwingChair. And that feeling brings healing and long term comfort like no other chair can.

SwingChair is Science Based

ErgoMotion DefinedSwingChair’s patented mechanism turns an office chair into an orthotic appliance. It perfectly counterbalances your natural movements, whether reaching for the phone, typing on your keyboard or even simply taking a deep breath.

This is made possible by the fact that your body’s center of gravity (“CG” in drawing), center of pelvic rotation (“HP”) are virtually contiguous. When seated, your center of lumbar flexion (“ICLF”) is at the same height above the seat as your centers of gravity. SwingChair’s mechanism makes full advantage of these coincident centers of movement by independently suspending the seat and backrest from a point (“CR-1”) near your center of gravity. When you sit down, the seat instantly moves to the ideal angle to support your legs and hips, and the backrest independently finds the ideal angle to support your back. Every time you move, they independently adjust to follow you. Not only do they counterbalance your smallest moves, SwingChair’s seat and backrest equalize pressure between your body and the cushions, preventing the “hot spots” common to chairs that require you to manually adjust the angles of the seat and backrest. Unrestricted natural human motion and the comfort that comes from sitting on cushions that do not produce hot spots.

Because the seat and backrest counterbalance your motion, you are comfortably supported in any posture that is considered safe and healthful according to a safety standard developed by the Human Factors and Ergonomics Society (“HFES”) in conjunction with the American National Standards Institute (“ANSI”).

Here is an excerpt from the ANSI HFES 100 Standard for safe postures for computer users. ANSI HFES 100 Standard
Notice how the cushions of the SwingChair perfectly match the position of the 3 recommended postures. SwingChair perfectly matches the position of the 3 recommended postures
This is made possible because the cushions pivot around your center of gravity. Notice how the angles of the cushions in the composite picture provide the full range of the 3 postures, and an infinite number in between. the cushions pivot around your center of gravity

Why You Need SwingChair

PROBLEM
Almost everyone experiences back pain and stiffness following hours of sitting. Sitting is a conventional office chair, even an expensive ergonomic chair, is like a straightjacket. You adjust it for comfort and then sit locked into that one posture because you concentrate on your work.

CAUSE
Sitting locks your spine and places a heavy load on your back’s bones, muscles and ligaments. When repeated for hours at a time, day after day, fatigue, pain and even long-term injury can occur. No amount of fiddling with an ergonomic chair can reduce the load on your spine; eventually you will experience fatigue, pain and possible long-term injury.

SOLUTION
SwingChair improves health, wellness and productivity by putting back into the office the single most important component to a healthy back: motion. SwingChairs relieve the stress and strain common to fixed posture chairs by enabling the same gentle, guided motion used by healthcare providers to rehabilitate injuries.

SwingChairs are literally an Orthotic Device: they gently guide your body’s natural desire to move, and keep that movement along paths of motion which are safe and healthy. SwingChairs prevent the twisting and turning motions that can bring on pain and injury.

Orthotics (Greek: Ορθός, ortho, “to straighten” or “align”) is a specialty within the medical field concerned with the design, manufacture and application of orthoses. An orthosis (plural: orthoses) is “an externally applied device used to modify the structural and functional characteristics of the neuromuscular and skeletal system”.[1] An orthosis may be used to:

  • Control, guide, limit and/or immobilize an extremity, joint or body segment for a particular reason
  • To restrict movement in a given direction
  • To assist movement generally
  • To reduce weight bearing forces for a particular purpose
  • To aid rehabilitation from fractures after the removal of a cast\
  • To otherwise correct the shape and/or function of the body, to provide easier movement capability or reduce pain
