Unfortunately, there is no 'one size fits all' with regard to mice/ wrist rests/ etc. However, in the majority of cases I've come across, wrist rests are generally not used correctly, which can often compound any problems. They should not be used to 'rest on' whilst using a keyboard/ mouse, only when taking a break from DSE use. If a person is putting unecessary pressure on the carpal tunnel area of the wrist whilst typing/ using a mouse, they can easily make the problem worse. IMHO, I'd recommend removing the 'mouse bean' and giving instruction on correct use of the mouse (i.e. moving the whole lower arm, not simply swivelling the hand on the wrist joint). Also, are there not keyboard shortcuts that the user could learn to further reduce mouse use?

As a CTS sufferer myself I found mice to be absolute agony whatever the support. I changed to a Trackball and the lack of the need to grip is bliss Bob

Thanks Guys, much appreciated. Badger

I am a believer in the joystick type controller, having suffered a bit with mouse trouble a few years ago. As teh-boy says, it changes the plane of your hand so there is no rotation of the wrist and it encourages the bigger muscles in your shoulder and upper arm to do the work. No problems since so I wouldn't change back at this stage. Also makes a great talking point when you have visitors to the office, as long as they don't think you spend your time gaming!

It's horses for courses. Try different things. None are expensive. Many years ago I started to suffer pain using a mouse. As a consultant I needed to type. I found using a graphic tablet worked for me. This uses an electronic pen on a pad - you can buy 'em from PC World, Tesco Direct etc. I wouldn't be without it. It's faster than a mouse too. Mine's made by Wacom.
