A-level students warned over text injury17 August 2006 Teenagers eager to share their recent A-level results with friends today are being warned about the potential health risks of texting. Some two million students are due to receive their A-level results today, but the Chartered Society of Physiotherapists is urging school-leavers to be wary of developing text message injury (TMI). The size of mobile phones is decreasing year-on-year, meaning the spaces between the buttons are also getting smaller. This means anybody tapping the keys to send a message is exposing themselves to injury from the small, repetitive movements. Claire Doherty, of the Association of Chartered Physiotherapists in Occupational Health and Ergonomics (ACPOHE), explained: "Though highly mobile and great for manipulative functions such as grasping, the thumb is not a very dextrous digit and can be prone to overuse, particularly when using one hand to grasp a phone and the thumb to activate the keypad. "Mobile phones are not ergonomically designed for excessive text messaging and too much can result in pain and swelling of the tendons at the base of the thumb and wrist." Ms Doherty suggests holding the phone in both hands in order to alternate between your fingers and thumbs when activating the keypad, as well as using the predictive text function.
She added: "Keep text sessions to five to 10 minutes and if you are expecting a response put the phone down in between while you wait to avoid muscle fatigue from continuous grasping." More information
