Tests to diagnose the Carpal Tunnel Syndrome often include an electromyogram. Smartphone users are often diagnosed with severe CTS, especially in the right hand. The proper solution for these severe cases is surgery.

However, preventing CTS is always better and more important, even though the operation is a simple one that takes only five minutes. The best prevention is to use the smartphone properly by using headphones instead of holding the phone for a long time. This is especially important for businessmen and other people who make intensive use of the phone. It is also recommendable to use a phone with touchscreen, as it is easier to write with these.
