PROBLEM TO BE SOLVED: To provide a measurement device that enables a patient performing rehabilitation to quantitatively measure a movable range of fingers to check a daily rehabilitation effect.SOLUTION: A measurement device includes a first projection part on which a thumb is hooked, a second projection part on which portions between the first joint and the tip of other fingers including at least one finger other than the thumb are hooked, and a moving mechanism for moving the first projection part and/or the second projection part so as to extend the other fingers in a reference plane crossing at least one of the first projection part and the second projection part. The moving mechanism stops the movement on condition that the force applied to the second projection part from the other fingers accompanying the movement becomes a predetermined level or more.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】リハビリテーションを行う患者が日々のリハビリテーションの効果を確認するために手指の可動域を定量的に計測できる計測装置を提供する。【解決手段】手の拇指を掛ける第一突出部と、前記手の拇指以外の少なくとも一指を含む他指の第一関節より先の部分を掛ける第二突出部と、前記第一突出部と前記第二突出部の少なくともいずれかと交差する基準面内で前記他指を伸展させるように前記第一突出部および/または前記第二突出部を移動させる移動機構と、を備え、前記移動機構は、前記移動に伴って前記他指から前記第二突出部に加わる力が所定以上になることを条件に前記移動を停止する。【選択図】図1
