メニエール病の重心動揺のスペクトル解析

抄録

Body sway was examined in 76 patients with Meniere's disease. Power spectra were analyzed by autoregressive models. Power density distributions showed large amplitudes in the whole range in the early stage of vertigo attacks, and they gradually declined from the high frequency levels. Low frequency sway of about 0.2-0.5Hz was manifest in left-right and anterior-posterior body sway. Furthermore, relatively high frequency sway of about 0.8-1.6Hz was present in left-right body sway.
