This apparatus consists of an arm restrainer, a pulley system, and a marker for a kymograph attached along the length of a wooden base. The components of the restrainer are made of brass, steel, and leather. The arm restrainer consists of two parallel metal poles elevated on a stand at each end. There is a pulley at one end of the wooden base opposite the arm restrainer. A wire extends from the end of the arm restrainer to the pulley. The kymograph stylus is attached to the top of the arm restrainer perpendicular to the length of the wooden base and restrainer.
