Of Americans between the ages of 18-29, 92% own a smartphone and spend 5 hours per day using these devices. Many medical professionals believe that this has led to text neck, which is neck pain caused by excessive smartphone use. People typically use their smartphone with the head bent forward, and this has been linked to long-term neck pain. Our study assesses the impact of 30 minutes of smartphone usage on reports of neck pain in people who have never had a neck-related injury. We will measure smartphone use, body position, and muscle strength to determine if it is possible to predict who develops neck pain when using a smartphone.
