I had been under chiropractic treatment for well over 4 months with minimal to no improvement. I decided to get rid of my wireless keyboard and mouse in favor of this keyboard with an integrated trackball. That was a heaven sent. The integrated trackball all but eliminated the constant movement of reaching for the mouse and back to the keyboard. Also I was able to put the keyboard in may lap and with the trackball right there I could keep my arms right by my side which is the recommended postion to avoid injury from prolonged use. I am very happy to report that the pain in my arm and my shoulder and the accompanying numbness is all gone now, and it happened only after I started using this keyboard.
