In order to achieve objective data to eventually measure the dexterity of hands, we examined 210 hands in 105 persons. These persons were divided into two groups: one group of people with jobs demanding unusual dexterity (musicians, typists, etc.), and another group with average occupational demands on the hand. As expected, we found that hand length and breadth and wrist circumference are always greater in the dominant hand of any individual. The thumb and small finger are always longer in the dominant hand. Joints' active range of motion are significantly higher in individuals whose occupations were particularly demanding.
为了获取最终用于衡量手部灵巧性的客观数据，我们对105人共210只手进行了检查。这些人被分为两组：一组是从事要求异常灵巧性工作的人（音乐家、打字员等），另一组是对手部职业要求一般的人。正如预期的那样，我们发现任何个体的优势手的手长、手宽和腕围总是更大。优势手的拇指和小指总是更长。职业要求特别高的个体的关节活动范围明显更大。
