In order to test the opposition and the counter-opposition (reposition) of the thumb, the method proposed here does not require the measuring of angles; rather, the hand itself is used as the system of reference. The opposition test consists of touching the four long fingers with the tip of the thumb: the score is 1 for the lateral side of the second phalanx of the index finger, 2 for the lateral side of the third phalanx, 3 for the tip of the index finger, 4 for the tip of the middle finger, 5 for the ring finger and 6 for the little finger. Then, moving the thumb proximally along the volar aspect of the little finger, the score is 7 when it touches the DIP crease, 8 on the PIP crease, 9 on the proximal crease of the little finger and 10 when it reaches the distal volar crease of the hand. This test is valid only if the first stages are possible: a crawling thumb in the palm is not an opposition motion. The counter-opposition test (or reposition test) needs the other hand as a reference system. The hand to be tested is set upon the table palm-down while; the other hand is laid on the table on its medial side, close to the tip of the first hand thumb; now this thumb is actively drawn up as high as possible.(ABSTRACT TRUNCATED AT 250 WORDS)
为了测试拇指的对掌和反对掌（复位）功能，本文提出的方法不需要测量角度；相反，手本身被用作参考系统。对掌测试包括用拇指尖触碰四个手指：食指第二指节外侧得1分，第三指节外侧得2分，食指指尖得3分，中指指尖得4分，无名指得5分，小指得6分。然后，拇指沿小指掌面近端移动，触及小指远侧指间关节横纹时得7分，触及近端指间关节横纹时得8分，触及小指近端横纹时得9分，到达手掌远侧近端横纹时得10分。只有在第一阶段可行时，该测试才有效：拇指在手掌内爬行不是对掌动作。反对掌测试（或复位测试）需要另一只手作为参考系统。被测试的手手掌向下放在桌子上，另一只手放在桌子内侧，靠近第一只手拇指尖；现在将这只拇指尽可能向上主动拉起。（摘要截选至250字）
