Differentiation of adductor-type spasmodic dysphonia from muscle tension dysphonia by spectral analysis
Objectives To determine the utility of spectral analysis in the differentiation of adductor-type spasmodic dysphonia ( AdSD ) from muscle tension dysphonia ( MTD ) . Study Design Prospect i ve blinded study . Methods Forty-seven sample s of AdSD-connected speech spectrograms from 27 subjects and 17 sample s of MTD-connected speech spectrograms from 15 subjects were selected from clinical charts and de-identified . These spectrograms were review ed independently and blindly by two speech language pathologists experienced in spectrography . The speech language pathologists design ated the spectrogram as consistent with AdSD and MTD , and these design ations were compared with actual clinical diagnoses . Results The ability to differentiate AdSD from MTD with spectral analysis was 94 % for rater # 1 and 98 % for rater # 2 . No MTD subjects were incorrectly diagnosed as having SD ( 100 % specificity ) . Conclusions This study suggests that experienced speech language pathologists can distinguish AdSD from MTD with a high degree of sensitivity and specificity based on spectral analysis . Spectral analysis is especially useful in cases where perceptual analysis and clinical evaluation alone are insufficient
