Stephen Dubner recalls his days at The New York Times (where he wrote stuff like this, this, and this), when newsrooms were full of two kinds of people: those suffering from wrist pain and those who feared they soon would. Many people had some sort of elaborate computer keyboard setup to remedy the situation — including Steve Levitt, who used a keyboard that folded up in the middle to ease his wrist pain. (He’d been keying in hours and hours of data. Levitt claims it was worth it, by the way: the data led to a paper about campaign spending, which he says was his “first good journal publication.”)
So where did all those white-collar carpal tunnel syndrome victims go?
We get the story from Bradley Evanoff, an M.D. and a professor at Washington University in St. Louis, where he studies occupational medicine. He traces the history of the ailment and points out that the epidemic seems to have started shortly after carpal tunnel syndrome became a compensable disorder:
EVANOFF: I think that prior to around 1985 or so there are really very few cases of carpal tunnel syndrome that are paid for out of workers’ compensation. And then you see this big growth between 1985 and about 1995 where many more cases are claimed as work-related. And this is the so-called epidemic of carpal tunnel syndrome that got people quite interested in and focused on CTS in the late 80’s early 90’s.
But was the computer keyboard really such a huge risk factor? Evanoff talks about what kind of workers are at the highest risk (it’s neither economists nor journalists), and what the numbers look like today. While we don’t hear about carpal tunnel syndrome much these days, it certainly hasn’t gone away: Evanoff estimates that 1 to 2 percent of American workers suffer from it. So why don’t we hear about it more often?
