Neuss (Germany), May 28:

Frequent incorrect use of a mouse when working on the computer can lead to a condition known as Repetitive Strain Injury (RSI), otherwise known as mouse arm, warn experts.

“Tingling, numbness, and weakness in the lower arm and hands are the first signs of overstressing of the tendons and nerves due to monotonous motion,” explains Frank Bergmann, head of the German Association of Nerve Doctors (BVDN).

“Constant clicking with the computer mouse and an unnatural hand position cause damage to the tissues that over the long term can lead to inflammation of the nerve fibres,” Bergmann says.

Even initially minor symptoms represent a danger that the brain may form connections between the pain and the activity of clicking. “The mouse click movement on its own can then trigger pain, even if the physical damage in the arm has already healed,” Bergmann points out.

Ergonomic working methods can prevent RSI.
