Finger and Arm Problems
In the same observational study that showed the commonality of bad neck posture, Gold also found that over 90 percent of texters held their wrists in a non-neutral wrist position (one that is more likely to cause strain). In a separate lab study, Gold and her colleagues reported that people who used physical keyboards (like on a Blackberry) and those who texted with only one thumb showed increased muscle activity in their forearms and wrists, which could lead to muscle problems. There are stands available that could hold our phones at a better level but very few people are going to go to those lengths to address poor phone posture. "I think variation is the most important thing," says Gold. "To vary your posture, alternate texting with calling, alternate being on your device with putting it away – is that even possible? – for certain periods of time."
