A device for shoulder flexibility rotation test includes a holding rod, a handle set, and an electronic control unit. The handle set includes first and second handle that allow hands to grasp the holding rod. One of the first and second handles can slip with the holding rod. The electronic control unit is mounted on either the first or the second handle, and it has a range finder for measuring the distance between the first and second handles, a controller to receive the aforementioned measuring result and to calculate flexibility at a percentile ranking, and a display which is connected electrically to the controller to display relevant information. Accordingly, by using the electronic design, the operator can receive the data of flexibility at a percentile ranking immediately after test without the need for manually checking from tables, thereby enhancing the convenience and practicability of measurement.一種肩膀柔軟度旋轉測定器,包含一握桿、一握把組,及一電控單元。該握把組具有設置在該握桿且可供雙手抓握的一第一握把與一第二握把,該第一、第二握把至少其中之一可依循該握桿滑移。該電控單元設置在該第一、第二握把其中之一,並具有測量該第一、第二握把間距的一測量器、用於接收前述測量結果且計算柔軟度百分等級的一中控器,及與該中控器電連接且用於顯示相關資訊的一載體。藉此,利用電子化的設計,在無需人工查表的情形下,使操作者可以在測量後立即得知肩膀柔軟度的百分等級,進而提升量測時的方便性與實用性。2‧‧‧握桿21‧‧‧桿件22‧‧‧端蓋23‧‧‧凹部31‧‧‧第一握把32‧‧‧第二握把321‧‧‧圍繞壁322‧‧‧栓孔4‧‧‧定位組41‧‧‧栓件42‧‧‧旋控件43‧‧‧彈性元件5‧‧‧電控單元51‧‧‧測量器511‧‧‧齒輪59‧‧‧開關
