Maltron has designed a keyboard to help prevent and alleviate symptoms of repetitive strain injury.

Maltron claims the two-handed keyboard has helped more than 600 RSI sufferers back to work.

There are also single-handed models for the disabled, and an "Expanded" model for those with muscular control and visual problems, and a head/mouth stick model.

Carol Huntley, a secretary at Newcastle University, has endorsed the keyboard which she says has helped her keep her job after suffering pain in her wrists, forearms, shoulders and neck.

The ergonomically-designed keyboard can be hired for a four-week trial for £10 a week.
