The intensive use of smartphones and tablets is giving rise to an emerging pathology: text neck, or thumb tendinitis linked to texting. More than 20% of users spend between 2 and 4 hours a day sending messages, a practice that adds to the already significant total screen time.
Digital De Quervain's Tenosynovitis
This inflammatory condition of the thumb and wrist, known in the professional and sports world as De Quervain's tenosynovitis, now affects intensive messaging users. It manifests as pain, swelling, numbness, and a decrease in functional strength. Diagnosis reveals visible inflammation on ultrasound, without arthritis.
Prevention and Treatment
Recommended preventive measures include:
- Limiting the number of texts and alternating fingers used
- Performing relaxation exercises every 30 minutes
- Avoiding systematically fixing the thumb in a bent position
In case of symptoms, treatment relies on rest, cold application, topical anti-inflammatories, and splinting. Severe cases may require injections, physiotherapy, or even surgery.
Observed Morphological Changes
A British study of 2000 people suggests that the most used thumb can become up to 15% larger in 13% of 18-34 year olds, while 8% develop a hollow in the little finger.
