  • Title: Low-frequency harmonic acceleration as a test of labyrinthine function: basic methods and illustrative cases.
    Author: Wolfe JW, Engelken EJ, Kos CM.
    Journal: Otolaryngology; 1978; 86(1):ORL-130-42. PubMed ID: 114912.
    Abstract:
    These preliminary findings reveal that low-frequency harmonic acceleration can be used to detect unilateral peripheral deficits that agree with caloric findings. However, the responses to sinusoidal acceleration are less variable than the caloric responses and allow one to more closely evaluate changes in pathology with time. Therefore, it appears that harmonic acceleration provides additional information that is useful in confirming other test results and that a complete otoneurologic evaluation should include this type of rotational testing.
