I have arthritis in my hands, and I find the best ergonomic grips for me are the Bontrager ones from Trek. I've tried a number of different brands. I have the Satellite Plus on one bike and the Satellite Elite on another. Try a pair - it's amazing the difference - not just in your hands, but all over including your back and shoulders. Your local Trek LBS should have them in stock.

BTW - I didn't like the Electra ones.
