We have examined 40 normal subjects (20 men and 20 women) to determine the ideal range of motion required to perform activities of daily living. The amount of wrist flexion and extension, as well as radial and ulnar deviation, was measured simultaneously by means of a biaxial wrist electrogoniometer. The entire battery of evaluated tasks could be achieved with 60 degrees of extension, 54 degrees of flexion, 40 degrees of ulnar deviation, and 17 degrees of radial deviation, which reflects the maximum wrist motion required for daily activities. The majority of the hand placement and range of motion tasks that were studied in this project could be accomplished with 70 percent of the maximal range of wrist motion. This converts to 40 degrees each of wrist flexion and extension, and 40 degrees of combined radial-ulnar deviation. This study provides normal standards for the functional range of motion of the wrist.
我们检查了40名正常受试者（20名男性和20名女性），以确定进行日常生活活动所需的理想活动范围。通过双轴腕部电子角度计同时测量腕部屈伸以及桡侧和尺侧偏斜的程度。所有评估任务在腕部伸展60度、屈曲54度、尺侧偏斜40度和桡侧偏斜17度时均可完成，这反映了日常活动所需的最大腕部活动度。本项目中研究的大多数手部放置和活动范围任务可在腕部最大活动范围的70%内完成。这相当于腕部屈伸各40度，以及桡尺侧联合偏斜40度。本研究提供了腕部功能活动范围的正常标准。
