A common task most of us are doing much more of than ever before is texting. This is an extremely wonderful and useful communication tool, but just like any other repetitive motion our body performs, we may be placing certain tendons at risk of overuse if our constant rapid-fire texting continues without paying attention to our extremely mobile and intricate thumbs and wrists. At A2 Physical Therapy, we strive to educate and assist our patients in being proactive regarding their overall health. If texting is something you cannot imagine having to modify or discontinue, give your thumbs and wrists a little TLC today.
The precise movements of our thumbs work the tendons of two specific muscles (abductor pollicis longus and extensor pollicis brevis) which can become irritated from repeated friction and overuse, leading to inflammation and degeneration of the tendons and their sheaths (the membrane surrounding and protecting a tendon). This puts pressure on the tunnel through which they travel. At certain angles of wrist and thumb movements, such as when we’re texting and gliding our thumbs sideways, these two tendons are at an increased risk of becoming irritated and inflamed. Patients with Texting Thumb (clinically referred to as De Quervain disease) may experience swelling, nodules, and increased pain on the thumb side of the wrist. A simple way to a test for this condition is called the Finkelstein test. Simply clasp the thumb in the palm with all four fingers and rotate downward at the wrist joint. A positive Finkelstein test is indicated when pain is experienced on the thumb side of the wrist.
Cortisone injections, surgical release, and immobilization are all options if conservative management isn’t enough. Actions we can take in physical therapy to prevent worsening of Texting Thumb symptoms include:
Activity modification, icing, and avoiding repetitive thumb and wrist movements are also indicated for anyone who experiences discomfort with the Finklestein test. For Texting Thumb, prevention and early treatment are especially important since these affected tendons can take months to heal once irritated.
So, here’s the takeaway: Put the phone down, do a few comfortable wrist and thumb stretches, and remember these delicate tendons and strong joints were designed to move, but not necessarily in a fixed position across a 2 inch screen thousands of times a day. Here are a few gentle stretches to get you started. Perform at a slow and controlled speed for 10 repetitions with a 5 second hold.
"I never thought I’d love PT, but now I do! I’m so appreciative that my first Pt experience has been with the most attentive and patient people possible. I’m thrilled the progress I’ve made and feel confident in my ability to continue improving at home. A huge thanks to the entire A2 team for being so welcoming and understanding. I truly can’t offer any recommendations, as you guys have a great thing going. (except for maybe more fruit infused water. Thanks again!"

"It was very helpful to be taught exercises I could do at home to alleviate the pain in my back and to make my stomach/diaphragm stronger. It was a great experience and I took away a lot of knowledge to help myself."
