Clinical value of sinusoidal harmonic acceleration test results. Site of lesion and side of lesion.


Sinusoidal harmonic acceleration tests can be used reliably to determine site and side of lesion. Results from 6000 patients collected over the past 10 years have shown that the temporal pattern of asymmetry can be reliably used to differentiate peripheral from central vestibular dysfunction. Peripheral cases tend to have a high level of asymmetry, with… (More)
