Wrist motion is distinct between touch screen and manual or digital devices.

Abstract

BackgroundRestricted motion during touch screen device use may contribute to wrist overuse injuries. Wrist radioulnar deviation and extension while using touch screen devices and digital or manual counterparts in male and female medical professional dominant and non-dominant hands were quantified to test the hypothesis that mobile touch screen device use reduces wrist motion.MethodsAn active motion detection system was used to record wrist motion of 12 participants while: tablet swiping and turning book pages; raising a cell and traditional phone to the ear; texting and typing; and entering numbers on a cell phone and manual calculator. Medial and lateral wrist surface range of motion (ROM) and minimum and maximum wrist radial-ulnar deviation and flexion-extension were quantified.ResultsDevice, sex and handedness effects were determined (PConclusionsSex and handedness should instruct touch screen, digital and manual device design and use for optimal performance and injury prevention.
