“Text Neck” is becoming an increasing cause of neck pain as we become more dependent on our mobile devices. A recent study in the journal of Neuro and Spine Surgery looked at the forces placed on the cervical spine at varying “texting” postures. They measured angles at Neutral (0deg), 15deg, 30deg, 45deg, and 60deg of cervical flexion. At the neutral position there was 10-12# of force on the vertebrae compared to 60# at 60deg of flexion; they compared this to “carrying an 8-year-old around your neck several hours per day”. Over time this can lead to cervical spine degeneration, pain, and arm numbness. So next time your texting or browsing, remember to keep your head up and you can save yourself alot of pain and medical bills in the future.
