Abstract
OBJECTIVE To investigate the frequency specificity of sinusoidal harmonic acceleration test(SHAT)and its clinical value in the classification of peripheral vertigo.METHODS 120 patients with peripheral vertigo and 40 healthy controls were selected.Based on caloric test results,patients were divided into bilateral symmetrical group,bilateral asymmetrical group,and bilateral hypofunction group.SHAT was performed,and gain and phase values were recorded at different frequencies.RESULTS Significant differences in gain and phase were observed among groups at multiple frequencies(P<0.05),most notably in the low-frequency range.SHAT results showed significant correlation with CP values,with gain at 0.01 Hz demonstrating the strongest correlation(r=-0.772,P<0.001).Equivalence analysis revealed that the three-frequency combination 0.02,0.08,0.64 Hz showed the strongest correlation with full-frequency examination results(gain r=0.994,phase r=0.867,both P<0.001).Intraclass correlation coefficient analysis indicated high consistency between the two methods(ICC=0.995,P<0.001),suggesting its potential as a rapid screening protocol.CONCLUSION Frequency specificity analysis of SHAT can provide objective and reliable diagnostic criteria for clinical classification of peripheral vertigo.关键词
