PEMBROKE PARK, Fla.l -

Maybe you can walk and chew gum at the same time, but can you walk and work at the same time?

While Local 10 hasn't had any troubles with its treadmill desk, a Wall Street Journal article says "active workstations" may not be a success story at every business.

According to the article, a 2011 Mayo Clinic study found that typing accuracy and speed went down 16 percent while walking when compared with sitting.

A few companies say they had to get rid of the desks because too many employees were falling.

Makers of various treadmill desks say people usually fall when they get too excited to try out the desk for the first time, and try to go too fast or do too much at once.

Other treadmill desks are made to stay below a certain speed to prevent injuries. The one at the Local 10 studios only goes up 4 mph.

Local 10's Todd Tongen introduced us to the treadmill desk last month after ABC talk show host Jimmy Kimmel admitted to using the desk to lose weight.
