Beware the `Blackberry Thumb` New repetitive stress injury caused by typing only with thumbs on hand-held devices. It`s rare these days to see a teenager without a cell phone in hand, texting for hours at a time, seemingly without health consequences. But, when older folks attempts to spend the day e-mailing, instant messaging and surfing the Web on a handheld device, repetitive stress injuries -- such as "Blackberry thumb" -- are much more likely to occur. "Blackberry thumb" because of the popularity of that particular model of wireless personal digital assistant (PDA), this repetitive stress injury occurs because these devices rely almost solely on the use of your thumbs for typing, instead of all your fingers. Any device that relies on the thumbs for typing can cause this type of injury because the thumbs simply weren`t designed for such use. "Blackberries and other PDAs can cause tendonitis from working in such a small space with the thumbs. "The problem is that people are doing the same activity for long periods of time that the body just wasn`t meant to do. Teens seem to do OK with it. It`s around age 40 or 50 the `itises`, [such as tendonitis], start to crop up." Symptoms of "Blackberry thumb" include pain and numbness in the thumbs and joints of the hand. "Try to do more on your computer. Don`t write phone books on your PDA. Limit yourself to `yes` or `no` answers when you can," |
