Kapandji评分被广泛用于记录拇指对位，是角度测量的唯一替代方法。我们的目的是验证Kapandji评分反映旋前角度的程度。我们招募了健康上肢的志愿者(33只手)和腕管综合征患者(20只手)。我们在拇指掌骨上安装一个小陀螺仪，测量两组Kapandji评分每个位置的旋前角和掌外展角度。Kapandji评分显示出强烈的天花板效应，两组Kapandji评分的角度大小增加在6分左右趋于平稳。卡潘吉得分大于6并不一定反映拇指对位。
The Kapandji score is used widely to record thumb opposition and is the only alternative to angular measurements. We aimed to verify the extent to which the Kapandji score reflects the angle of pronation. We recruited volunteers with unaffected upper limbs (33 hands) and patients with carpal tunnel syndrome (20 hands). We attached a small gyroscope to the thumb metacarpal and measured the pronation and palmar abduction angles at each position of the Kapandji score in both groups. The Kapandji score showed a strong ceiling effect, and the increase in angle size at each Kapandji score levelled off around a score of 6 in both groups. A Kapandji score greater than 6 does not necessarily reflect thumb opposition.
