万花筒 2009-07-17&07-18 发短信得肌腱炎？！（在线收听）

13-year-old Bailey Baker's thumbs are in constant motion, sending text messages to her friends again, again and again. Last month may have been her best month ever, when she texted 8000 times. Now she's feeling the pain. Just mainly back and neck problems and thumb numbness and it hurts. Doctor Jane Sadler’s seeing more and more teens who simply text until it hurts. She says parents including Bailey's mother have no idea how much their kids are texting.

"I was thinking she was texting about 25 texts a day. Wrong.

We have uncovered a problem."

And it doesn't take Doctor Sadler long to isolate the problem. She gives Bailey the once over

and learns she's texting about 200 times a day.

"Well, Bailey, what you have is texting teen tendonitis." That's right. Bailey has TTT.

“A lot of them report pain in their thumbs

or their elbows or their back and neck. And when we look into it or investigate a little bit further, we see that commonly the culprit is texting.”

Doctor Sadler says back soreness is caused by poor posture when texting. Bailey often texts for up to two hours a day. There’s a lot of wear and tear on the thumbs which over time can break down.

"What I tell them is , hey, you might be normal now. But when you are 40 or 50, you can get arthritis." Doctor Sadler expects a boom in thumb-joint replacement surgeries over the next several decades. For Bailey, Doctor Sadler suggested exercises like this to strengthen her hands.

School's out, but Bailey got a lesson about the downside of all that texting.

"For I don't think texting can mess like make your hands feel so bad."
