A new technique for quantifying wrist circumduction was developed and evaluated using a biaxial flexible electrogoniometer. The reliability and validity of the electrogoniometer for the measurement of wrist motion were first tested, and then the device was applied clinically. The reliability tests demonstrated sufficient accuracy of the device. Also, validity of the measurement was recognized because the tests simulating wrist circumduction and cineradiography revealed that it could accurately detect the angle between the long axis of the forearm and the third metacarpal bone. Lissajous's figure was made from the two channel signals of the electrogoniometer, and the Range of Motion index for wrist circumduction was newly defined from this figure. This index represents the dynamic range of motion of wrist circumduction. Ten healthy men (ages 19-31 years) and three patients with wrist disorders were studied. In the patients, Lissajous's figures and Range of Motion indexes were markedly different from the healthy. In addition to this study, preliminary data on the 'velocity-angle loci' of healthy men during wrist circumduction were obtained for further detailed analysis.
开发了一种使用双轴柔性电子测角仪量化腕关节环转的新技术并进行了评估。首先测试了电子测角仪测量腕关节运动的可靠性和有效性，然后将该设备应用于临床。可靠性测试证明了该设备具有足够的准确性。此外，由于模拟腕关节环转和X线电影摄影的测试表明它可以准确检测前臂长轴与第三掌骨之间的角度，因此该测量的有效性得到了认可。从电子测角仪的两个通道信号绘制了李萨如图形，并从该图形中新定义了腕关节环转的运动范围指数。该指数代表腕关节环转的动态运动范围。研究了10名健康男性（年龄19 - 31岁）和3名腕关节疾病患者。在这些患者中，李萨如图形和运动范围指数与健康人明显不同。除了这项研究，还获得了健康男性在腕关节环转过程中“速度 - 角度轨迹”的初步数据，用于进一步详细分析。
