Reaching out into space may also reveal insufficient rotation through the upper extremities and rotation of the trunk.
藉由上肢和軀幹的空間伸展，也會顯示肢體的轉動不足。

A lack of rotation can be observed in the hand as well when a child maintains the thumb in adduction during grasping activities.
在握持時，兒童的拇指保持內收，也可觀察到手部缺乏轉動的情形。

Pincer and pencil grasps require the thumb to oppose the index finger in a pattern of rotation; therefore, the poor rotation component may negatively impact hand function as well.
在握持鉗子和鉛筆時，則需進行拇指跟食指反向的轉動模式。因此，轉動不足的部位也負面影響到手部的功能。
