Smartphone Use Affects Posture

Using surface electromyography and a digital camera, researchers investigated changes in posture and muscle activation among 18 participants while they interacted with their electronic device. The results revealed that smartphone use induced a more flexed posture on the neck and trunk compared with desktop computer use. The researchers also found that participants began to experience neck and back pain if they used their smartphone for longer than 15 minutes. The findings suggest that healthcare providers should consider the influences of smartphone use in posture and muscle activity in the evaluation,intervention, and prevention of neck and trunk conditions.
