No matter how you do it, prolong sitting is potentially harmful !

Following several years of research on ergonomics and posture, Anne Fenety, PhD, PT of Dalhousie University concludes that ??there is no such thing as a ?good? sitting posture?

What does that mean? It means that whether you sit with a roll or not, in an anterior pelvic tilt or not… no matter how you do it, prolong sitting is potentially harmful to the spine.

You think the fancy expensive ergonomic chairs are good? Think again!

Motion studies of people sitting while keyboarding conclude that these ?comfortable? ergonomic chairs actually decrease the amount of ?fidgeting? while the less expensive ?normal? chairs force people to fidget more?which is a good thing!

Clinical Relevance: Fidgeting when sitting is GOOD

Considering the tissue creep phenomenon, sitting in a single static position must be limited to 20 minutes, and following that one must stand up and walk around even for a few seconds.

?Comfortable Ergonomic? chairs that restrict movement are BAD

The more static the sitting posture? the worse it is. Patients may be advised to regularly change their desk and chair height on different days and forget about the 90, 90, 90 degree rule of ergonomics.
