Restricted 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.
An 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.
Device, sex and handedness effects were determined (P<0.05). Maximum medial radial deviation and ROM were greater using a cell versus traditional phone. Maximum medial radial deviation was higher in the nondominant wrist during backward tablet swiping and while backward page turning versus tablet swiping. Maximum and minimum medial extension angles and ROM were greater while typing versus texting. Female nondominant hand maximum lateral extension and ROM were greater for typing versus texting and maximum medial extension and lateral extension ROM greater during manual versus cell phone calculator use with handedness combined. Maximum lateral extension and ROM were greater in females versus males using manual calculators.
Sex and handedness should instruct touch screen, digital and manual device design and use for optimal performance and injury prevention.
在使用触摸屏设备时限制运动可能会导致手腕过度使用损伤。本研究旨在量化男性和女性医务工作者惯用手和非惯用手中使用触摸屏设备和数字或手动设备时的腕关节桡尺偏和伸展情况，以检验使用移动触摸屏设备可减少腕关节运动这一假设。
使用主动运动检测系统记录 12 名参与者的腕关节运动情况，包括：平板电脑滑动和翻书页；将手机和传统电话举到耳边；发短信和打字；以及在手机和手动计算器上输入数字。量化了腕关节的掌侧和背侧表面活动范围（ROM）以及最小和最大的腕部桡尺偏距和屈/伸角度。
确定了设备、性别和手性的影响（P<0.05）。与传统电话相比，使用手机时最大的掌侧桡偏距和 ROM 更大。与平板电脑滑动相比，在向后滑动平板电脑和向后翻页时，非惯用手腕的最大掌侧桡偏距更高。与发短信相比，打字时最大和最小的掌侧伸展角度和 ROM 更大。女性非惯用手打字时的最大背侧伸展和 ROM 大于发短信，而手动与手机计算器相比时，最大掌侧伸展和背侧伸展 ROM 更大，且与手性相结合。与男性相比，女性使用手动计算器时最大背侧伸展和 ROM 更大。
性别和手性应该指导触摸屏、数字和手动设备的设计和使用，以实现最佳性能和预防损伤。
