On signal analysis of three-dimensional nystagmus.
Nystagmus needs to be stimulated for healthy subjects, but in patients it can also be spontaneous. By recording spontaneous nystagmus it is possible to reveal underlying disorders of the semicircular canals of the inner ear. We developed a signal analysis technique for this purpose and tested it with 28 otoneurological patients who had disorders in their semicircular canals. Our test results support the postulate how nystagmus should appear under these conditions and agree with results presented in the otoneurological literature.
