Overusing Handheld Devices Can Hurt

Wireless, handheld devices such as BlackBerrys are designed to help make our lives more convenient. But they also can hurt us. Repetitive motion of our thumbs and fingers while using these devices can result in arthritis or tendonitis.

BlackBerry Thumb is a term used to describe injuries that cause strain and stress from repetitive and excessive use of such handheld gadgets. The thumb is often used to type, but it lacks the dexterity to withstand repetitive use.

For youth, those who repeatedly play handheld video games also can suffer injuries that are caused by strain to their thumbs, fingers, hands, and wrists.

Symptoms associated with overusing your handheld device include throbbing, aching, numbness, or burning in your hand or wrist. If arthritis or tendonitis is diagnosed, treatment options include icing, splinting, bracing, and if necessary, a cortisone injection. Long-term nerve damage is rare, but sometimes surgery may be required.

To help avoid injury, adults and youth should try to use the device less and rest their thumbs. BlackBerry users should type shorter and fewer messages and use a stylus or pen.
