title: An aid for the diagnosis of a vertical muscle paresis.
abstract: I have described a simple method involving a diagram and circles for dealing with the results of the three-step examination of the vertical muscles used in diagnosing a single paretic muscle. It may prove beneficial for those who evaluate these muscles infrequently as using the diagram allows immediate appreciation of the functional anatomy of the muscles, the physiologic implications of each step of the examination, and a permanent record of the selection through elimination of the paretic muscle.
