Prolonged head flexion (bending forward at the neck) while using a smartphone is a risk factor for #neck pain. Researchers measured the forward flexion of smartphone users and found that most participants maintained head flexion of 33-45 degrees when using their smartphone. Furthermore, they note that head flexion was significantly larger when texting compared with other smartphone-related tasks, and greater while sitting than standing. The results suggest that texting could be a main contributing factor in the incidence of neck pain of heavy smartphone users.
