    In diagnosing vestibular disease, it is necessary to analyse nystagmus. However, it is difficult to record nystagmus during attacks of vertigo because of technical problems. In this paper, we introduced a “portable” Electronystagmography apparatus (NYSTAGMAN), developed by HORTMANN Company, and showed its clinical usefulness.
    The system consists of two parts, a dig ital recorder for ENG and special goggles with built-in electrodes.
    We observed cases of vertigo in the acute stage, and found the device to be useful in about 80%of cases.
    In conclusion, the device makes ENG recording possible anywhere, at anytime, and for anyone.
