In 50 right handed and 50 left handed subjects we researched the phenomenon of spreading fingers. In the right hand of right-handers we found the smallest angels between fingers, in the right hand of left-handers we found the biggest angels between the spreaded fingers. The higher the dominance of the hand, the lower is the phenomenon of spreading fingers. We assumed smaller motor units at the side of dominance.
在50名右利手和50名左利手受试者中，我们研究了手指伸展现象。在右利手者的右手中，我们发现手指间的角度最小；在左利手者的右手中，我们发现伸展手指间的角度最大。手的优势程度越高，手指伸展现象越不明显。我们推测优势手一侧的运动单位较小。
