    • n ergograph An instrument for recording muscular work; a recording dynamometer or ergometer: used especially in the study of muscular fatigue. The work recorded by the ergographs ordinarily employed is that done by a single finger pressing against a spring or pulling against a weight. In Mosso's instrument, the earliest form of the ergograph, there are three principal parts: the padded arm-rest, with arm-straps and brass tubes which hold the unused fingers in position; the weights, attached to a cord which passes over a pulley to a finger-cap adjusted to the lifting finger; and the recording carriage, which moves between metal guides with the movement of finger and spring, and carries a writing-point by which the ergogram or work-record is traced upon the smoked surface of a kymograph drum. An ergograph of this type is termed a weight ergograph. In other forms of the instrument, the compression of a spring replaces the pull-up of the weight: spring ergographs have been devised, for example, by Cattell and Binet. In yet other forms, among which Meumann's ergograph may be mentioned, there is no graphic record; the recording carriage and kymograph are replaced by a work-adder.
