ABSTRACT
INTRODUCTION:
Adductor spasmodic dysphonia (ADSD) is characterized by involuntary laryngeal muscle spasms. Due to the lack of a quantitative evaluation method, most measurements have demonstrated difficulty in validity and reliability for diagnosing ADSD. This study aimed to establish a novel indicator for ADSD and determine its diagnostic effects.METHODS:
We investigated 98 voice samples from 49 patients with ADSD and 49 healthy subjects. A sustained vowel was recorded by a high-definition audio recorder. Voice samples underwent regular acoustic evaluation and a novel global dimension method. Global dimension (GD), Jitter, Shimmer, HNR, Frequency shift, and CPPS were measured for both groups.RESULTS:
Statistical analysis revealed that the global dimension method effectively differentiated ADSD patients from healthy subjects (P<0.001, D'>0.8). Subsequent multiclass receiver operating characteristic analysis demonstrated that GD possessed the most significant classification accuracy (AUC = 0.988) compared with other acoustic parameters.CONCLUSION:
GD was an effective metric for objective differentiation between ADSD patients and healthy subjects. This metric could assist clinicians in the diagnosis of ADSD patients.
