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 the 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 at a perpendicular angle to the length of the wooden base and restrainer.
