Parkinson's disease causes tremors or stiffness that can turn everyday tasks such as eating,

brushing teeth, or writing into frustrating chores. A few years ago, a company called Liftware

developed forks and spoons that respond to shaking by steadying the

utensil, making it easier to enjoy a meal. Now researchers at Imperial College and the Royal College of

Art in London are developing a device called the Arkpen that vibrates to stimulate muscles in

the hand. The vibrations could help Parkinson's patient's handwriting, in part by counteracting what's known as micrographia,

which causes writing to be small and barely legible.

Micrographia is often an early sign of Parkinson's and afflicts about 5% of patients.

The researchers, who formed a company called Dopa Solution, have not published their results,

but they say that 12 out of 14

Parkinson's suffering their vibrating prototype arc pen were able to write larger, clearer characters

than they could with a normal pen. Dopa hopes to also develop tools, brushes, and even computer

mice that work like their pen. Not a cure, of course, but certainly a way to help users

have a more satisfying life. Thanks for the minute. For Scientific American 60 Second Science,
