Two-point discrimination in the hand and forearm is best during the third decade of life. In the fingertips, the ulnar digits are more discriminating than the radial digits. Males and females have equal two-point discrimination during each age decade. Fingertips are twice as discriminating as the thenar and hypothenar areas, and the thenar and hypothenar areas are twice as discriminating as the volar side of the wrist; the wrist is twice as discriminating as the forearm. The Kleinert and Kutler flaps demonstrated the best two-point discrimination among the repaired fingertips.
手部和前臂的两点辨别觉在生命的第三个十年期间最佳。在指尖，尺侧手指比桡侧手指的辨别能力更强。在每个年龄十年中，男性和女性的两点辨别觉相等。指尖的辨别能力是大鱼际和小鱼际区域的两倍，大鱼际和小鱼际区域的辨别能力是腕掌侧的两倍；腕部的辨别能力是前臂的两倍。在修复后的指尖中，克莱纳特（Kleinert）皮瓣和库特勒（Kutler）皮瓣表现出最佳的两点辨别觉。
