Can you recommend a smaller sized mouse suitable for seniors. My wife has arthritis in her right hand and prefers a smaller sized "mini-mouse"?

I bought her a wireless Mac Mouse, but she can only use it for a short time. She uses a very small mouse with a slightly rubberized surface at work. Thanks for any suggestions.
