What is it about?
While it has long been suspected that muscle fatigue increases susceptibility to injury, there is no hard proof. This study for the first time shows that sustained fatiguing exertions of the neck cause the cervical spine to bend further, thus modifying neck mechanics and propensity for injury.

Why is it important?
The study presents the most compelling evidence relating the prolonged sedentary work or overuse of electronic devices to the excessive stress experienced by the neck, and to the rising prevalence of neck pain. The foundational knowledge also provides a scientific rationale for dos and don'ts (e.g., dropped head position and/or heavy head-wearables) to prevent or deter the development of neck pain.
