PROBLEM TO BE SOLVED: To provide method and device for acquiring the data necessary for the direct evaluation of deterioration conditions of shock buffering tissues of a joint only by measuring responses based on subject's physical actions.SOLUTION: The device includes acceleration sensors attached to one side of the joint to be measured, another acceleration sensor attached to the other side thereof, a means for detecting the difference of vibrations timing generated by the two acceleration sensors and a means for storing the correspondence data between the vibration timing differences and the deterioration conditions of shock buffering tissues of the joint. When the joint has its both side parts mutually situated in linear relations to each other, the device evaluates the deterioration conditions of shock buffering tissues of the joint according to the difference of vibration timing between the two acceleration meters generated by a force applied to one side of the joint. |
