The Arthritis Research Campaign has changed its name to Arthritis Research UK as part of a rebrand that it hopes will raise awareness of both the charity and the condition.
The charity has also overhauled its website as part of the move, which was announced this week. Arthritis Research UK will promote its name and new goals, which include increasing its lobbying role on behalf of arthritis sufferers, through a series of advertisements in national magazines and newspapers.
A spokeswoman for Arthritis Research UK said: "The name change is part of a new way forward. We are not only asserting ourselves in the fight against arthritis, but also reaching out to engage people who don't realise the problems associated with the condition."
She declined to give a figure for the cost , but said "the bulk of the cost of the rebranding project" was contained within the 19 per cent of the charity's income that was spent on running costs in the current financial year.
Dr Liam O'Toole, chief executive of Arthritis Research UK, said: "We are making a number of changes and a new name is one of them. We are relaunching the fight against arthritis and we will be building on our leadership role in research, which we expect to have a more direct impact on the lives of sufferers."
