Is your laptop a pain in the neck?

When Ram Viswanadha began using a laptop at work, he decided to shelve his clunky old desktop PC for good. The notebook's size, speed and memory blew the older computer away.

What the 30-year-old Silicon Valley software engineer didn't bargain for was a severe case of repetitive strain injury--and a three-month disability leave--from hunching over his laptop day in and day out for four years.

Viswanadha's situation is a worst-case scenario in workplace ergonomics, but stories like his are becoming more common, according to doctors and ergonomic experts across the country. As people ditch desktop computers to work full time on laptops, doctors expect to see a lot more pains, strains and injuries among white collar workers.

What's new:
Notebook PCs may be convenient, but they're also an ergonomic nightmare. And more and more people are discovering that the hard way.

Bottom line:
The good news is that laptop-related repetitive stress injuries are avoidable. Peripherals such as computer mice and separate keyboards can prevent some of the problems, as can lifestyle choices and work habits.

"When you look at the design, laptops were never (meant) as a replacement for a desktop computer," said Alan Hedge, director of the Human Factors and Ergonomics Laboratory at Cornell University. "The idea was portability for occasional use. It was never intended to be a machine you would work at for eight hours a day, 52 weeks a year."

More than 9,200 nongovernment workers reported missing a day or more of work because of typing and keyboarding-related injuries in 2003, according to figures from the U.S. Bureau of Labor Statistics. Ninety-two percent of those cases were associated with worker motion or position, the bureau said. More than a third those workers missed over a month of work because of their injuries.

For notebook computer use, such statistical information on injuries is scarce, but doctors report a steady stream of new patients who've overdone it on the machines. That's not surprising given the boom in laptop sales. Nearly 49 million notebooks were sold in 2004 worldwide, almost double the number sold in 2000, according to market researcher IDC. The devices account for more than a quarter of the computer market, and are set to surpass desktop sales in the United States by 2008, IDC said.

The main problem with laptops is that the screen and keyboard are so close together. Without the aid of peripherals, laptop users have two choices, neither of which would win them any points for posture. They can cramp their neck down to view the monitor or they can elevate the machine to eye level, which can wreak havoc on shoulders and arms.

And the wrists lose regardless, because the keyboard is so small, leading to awkward hand positioning.

"These are all recipes for disaster for your body, and your musculoskeletal system especially," said Nicholas DiNubile, an orthopedic surgeon in Havertown, Penn., a Philadelphia suburb.

Laptops can cause other physical woes. People have been burned by the heat the machines generate. The temperature issue can also cause fertility problems in men who place the machines on their laps for prolonged periods. Frequent travelers can put strain on backs, hands and shoulders by lugging a laptop around.

For Viswanadha, neck strain was the root of injury. His doctors said spending so much time on the laptop had shortened his neck muscles,
