In a bioinstrument system S of the present invention, a processor unit 121 in a bioinstrument device 108 obtains information indicative of displacement of two fingers in deformed state from distance between the two fingers and calculates a finger-tapping force by using the obtained information and a predetermined fingertips stiffness function retrieved from a storage unit 122. This provides a method for inspecting for neurological disorders in consideration of the finger-tapping force.
