Fig. 2: Rounded back holds many potential health risks and speeds up degeneration. About the author Mr Veli-Jussi Jalkanen is the Chairman of the Board of Salli Finland and CEO of Salli China. Being a specialist in work environment and preventive health, and having a riding background, he developed the Salli Saddle Chair and Salli sitting health concept. He has found strong connection between traditional / poor sitting and many common degenerative illnesses. The unique swinging and divided Salli seat is exported to over 60 countries. à he pains caused by the common back degeneration, which is the result from traditional ergonomics, are the constant nuisance in dental work. Avoiding this threat is relatively easy with the new better posture that can be achieved by sitting on a divided swaying saddle chair, using looser clothes, and positioning oneself closer to the patient. àhis concept includes also numerous other advantages. àhe leading Finnish ergonomics company has developed the solution for the dental ergonomics and health problems, and is spreading it around the world. Why are lower back degeneration and pains so common? àormal 90/90 sitting (90 degree angles in hips and knees) is actually C/90 sitting with the rounded back. àhus the facets are open and not carrying their part, and the pressure on the discs is 30% bigger. àhe increased one-sided disc pressure is the main reason for disc prolapse (Fig. 1). àhe roundness of the back also stretches the back muscles and makes them tense, slowing down the blood and lymph circulation. àhe weakened oxygen and nutrient intake and waste removal degenerate all tissues in the (lower) back, causing numerous impacts and pains. àhe missing vertebral arteries around the à5 halves the flow of nutrients and oxygen for the à4 and à5, and that is why they are the first to degenerate (Fig. 2). àealtà & wellàeàng
