title: A computerized Three-Step Test.
abstract: A computerized Three-Step Test is described that uses a BCD integrated circuit chip instead of a computer with a software package. This is accomplished by coding the Three-Step Test in terms of a three-letter word. The operation of a device is described which is able to diagnose isolated cyclovertical muscle palsies, once the clinical data is known, by setting the position of three switches.
