    http://ergo.human.cornell.edu/ergoguide.html
    Creating a good ergonomic working arrangement is important to protecting your health. The following 10 steps are a brief summary of those things that most Ergonomists agree are important. If you follow the 10 steps they should help you to improve your working arrangement.
    You can also use the Computer Workstation Checklist to help to pinpoint any areas of concern and take a look at the 'Computer Workstation summary' diagram' for specific tips. However, every situation is different, and if you can't seem to get your arrangement to feel right or you are confused about some of the following recommendations you should seek professional advice.

    I haven't read thru the full thread,but I read enough to see that most of you are dying to have back issues...

    First and foremost,get a seat where your knees can be below hip level.

    Get up and move or switch positions every 30 minutes or so.

    Do not use the backrest as the sole support for your torso.

    If you cant sit on a stability ball for at least 30 minutes,get off your fat asses and do some core training.Work your posterior chain,and make sure you can maintain neutral spine ...

  4. just curious, how many of you trade standing up? no, i'm not talking about being long NG before the inventory report yelling "come on baby huge drawdown, it's been freezing this week!"

    everyone i've read/heard about swears by them but i can't imagine standing in one place for 10-12 hours a day straight.

    not for nothing, but forcing people (i.e. terrorists/suspects/really unlucky innocent people accused of being a terrorist) to stand in one place for long periods of time is a somewhat effective interrogation technique. i say somewhat b/c if i forced you to stand for the rest of eternity and said "it won't stop until you tell me something" i'd prob just break down and say "fine - i'll admit i'm a jack hershey follower just let me sit down".

    Your Office Chair Is Killing You
    Meet public enemy No. 1 in today's workplace
    By Arianne Cohen



    If you're reading this article sitting down—the position we all hold more than any other, for an average of 8.9 hours a day—stop and take stock of how your body feels. Is there an ache in your lower back? A light numbness in your rear and lower thigh? Are you feeling a little down?
    These symptoms are all normal, and they're not good. They may well be caused by doing precisely what you're doing—sitting. New research in the diverse fields of epidemiology, molecular biology, biomechanics, and physiology is converging toward a startling conclusion: Sitting is a public-health risk. And exercising doesn't offset it. "People need to understand that the qualitative mechanisms of sitting are completely different from walking or exercising," says University of Missouri microbiologist Marc Hamilton. "Sitting too much is not the same as exercising too little. They do completely different things to the body."
    In a 2005 article in Science magazine, James A. Levine, an obesity specialist at the Mayo Clinic, pinpointed why, despite similar diets, some people are fat and others aren't. "We found that people with obesity have a natural predisposition to be attracted to the chair, and that's true even after obese people lose weight," he says. "What fascinates me is that humans evolved over 1.5 million years entirely on the ability to walk and move. And literally 150 years ago, 90% of human endeavor was still agricultural. In a tiny speck of time we've become chair-sentenced," Levine says.
    Hamilton, like many sitting researchers, doesn't own an office chair. "If you're standing around and puttering, you recruit specialized muscles designed for postural support that never tire," he says. "They're unique in that the nervous system recruits them for low-intensity activity and they're very rich in enzymes." One enzyme, lipoprotein lipase, grabs fat and cholesterol from the blood, burning the fat into energy while shifting the cholesterol from LDL (the bad kind) to HDL (the healthy kind). When you sit, the muscles are relaxed, and enzyme activity drops by 90% to 95%, leaving fat to camp out in the bloodstream. Within a couple hours of sitting, healthy cholesterol plummets by 20%.
    The data back him up. Older people who move around have half the mortality rate of their peers. Frequent TV and Web surfers (sitters) have higher rates of hypertension, obesity, high blood triglycerides, low HDL cholesterol, and high blood sugar, regardless of weight. Lean people, on average, stand for two hours longer than their counterparts.
    The chair you're sitting in now is likely contributing to the problem. "Short of sitting on a spike, you can't do much worse than a standard office chair," says Galen Cranz, a professor at the University of California at Berkeley. She explains that the spine wasn't meant to stay for long periods in a seated position. Generally speaking, the slight S shape of the spine serves us well. "If you think about a heavy weight on a C or S, which is going to collapse more easily? The C," she says. But when you sit, the lower lumbar curve collapses, turning the spine's natural S-shape into a C, hampering the abdominal and back musculature that support the body. The body is left to slouch, and the lateral and oblique muscles grow weak and unable to support it.
    This, in turn, causes problems with other parts of the body. "When you're standing, you're bearing weight through the hips, knees, and ankles," says Dr. Andrew C, Hecht, co-chief of spinal surgery at Mount Sinai Medical Center. "When you're sitting, you're bearing all that weight through the pelvis and spine, and it puts the highest pressure on your back discs. Looking at MRIs, even sitting with perfect posture causes serious pressure on your back."
    Much of the perception about what makes for healthy and comfortable sitting has come from the chair industry, which in the 1960s and '70s started to address widespread complaints of back pain from workers. A chief cause of the problem, companies publicized, was a lack of lumbar support. But lumbar support doesn't actually help your spine. "



    You cannot design your way around this problem," says Cranz. "But the idea of lumbar support has become so embedded in people's conception of comfort, not their actual experience on chairs. We are, in a sense, locked into it."
    In the past three decades the U.S. swivel chair has tripled into a more than $3 billion market served by more than 100 companies. Unsurprisingly, America's best-selling chair has made a fetish of lumbar support. The basic Aeron, by Herman Miller, costs around $700, and many office workers swear by them. There are also researchers who doubt them. "The Aeron is far too low," says Dr. A.C. Mandal, a Danish doctor who was among the first to raise flags about sitting 50 years ago. "I visited Herman Miller a few years ago, and they did understand. It should have much more height adjustment, and you should be able to move more. But as long as they sell enormous numbers, they don't want to change it." Don Chadwick, the co-designer of the Aeron, says he wasn't hired to design the ideal product for an eight-hour-workday; he was hired to update Herman Miller's previous best-seller. "We were given a brief and basically told to design the next-generation office chair," he says.
    The best sitting alternative is perching—a half-standing position at barstool height that keeps weight on the legs and leaves the S-curve intact. Chair alternatives include the Swopper, a hybrid stool seat and the funky, high HAG Capisco chair. Standing desks and chaise longues are good options. Ball chairs, which bounce your spine into a C-shape, are not. The biggest obstacle to healthy sitting may be ourselves. Says Jackie Maze, the vice-president for marketing at Keilhauer: "Most customers still want chairs that look like chairs."
    Recently Levine talked to Best Buy (BBY), Wal-Mart (WMT), and Salo accounting about letting him design their offices and keep people walking and working as much as possible. Levine jerry-rigged an old 1- to 2-mph treadmill to stand under a desk and put a handful of them in conference rooms. Those who wanted could have walking desks in their offices, and he partnered with Steelcase to manufacture a $4,500 version of the machine. "Within two weeks, people basically get addicted to walking and working," says Levine. "You just need to give them the chance."
