Following our previous study about mobility of the three-phalangeal fingers we have measured flexion in the interphalangeal (IPP) and metacarpophalangeal (MPP) thumb joints as well as thumb opposition (hyperadduction) in university students (52 males and 49 females), seniors (30 males and 30 females) and pianists (21 males and 31 females). In the student control group we did not find difference between males and females or right and left hand, unlike in the previous study of three-phalangeal fingers. The MPP has greater flexion variability than the IPP joint. We have recorded greater limitation in all measured movements in seniors, in the thumb opposition significantly greater in males than in females. Pianists, on the other hand, always show greater thumb opposition, while greater flexion was significant only in the MPP joint in males. We did not record a difference between right and left hand in seniors or pianists.
继我们之前关于三节指骨手指活动度的研究之后，我们测量了大学生（52名男性和49名女性）、老年人（30名男性和30名女性）以及钢琴家（21名男性和31名女性）的拇指指间关节（IPP）和掌指关节（MPP）的屈曲情况以及拇指对掌（过度内收）情况。在学生对照组中，我们没有发现男性与女性之间或右手与左手之间存在差异，这与之前关于三节指骨手指的研究不同。MPP关节的屈曲变异性比IPP关节更大。我们记录到老年人在所有测量动作中受限程度更大，在拇指对掌动作中男性受限程度明显大于女性。另一方面，钢琴家的拇指对掌动作总是更大，而仅在男性的MPP关节中屈曲程度更大才具有显著性。我们没有记录到老年人或钢琴家的右手与左手之间存在差异。
