Differential diagnosis of adductor spasmodic dysphonia and muscle tension dysphonia using acoustic parameters

Objective:The study aimed at differentiating Adductor Spasmodic Dysphonia (ADSD) from Muscle Tension Dysphonia (MTD) using acoustic measurements . Method: Perceptual as well as acoustic analysis of the voice was done on 12 patients of Adductor Spasmodic dysphonics and Muscle tension dysphonics each. The age of these patients ranged between 30 to 64 years . Results: Adductor spasmodic dysphonics...

Tremor in speakers with spasmodic dysphonia

the objective of this work is the estimation of vocal tremor in patients with spasmodic dysphonia before and after treatment, and the comparison of their tremor characteristics with those estimated from healthy speakers. as an outcome, a new tremor attribute is introduced, the deviation of the modulation level and a novel method is proposed for classifying speakers according to the prevalence o...

Review of differential diagnosis and management of spasmodic dysphonia.

PURPOSE OF REVIEW The recent literature on spasmodic dysphonia is reviewed with regard to pathogenesis, differential diagnosis, treatment options, audits, and current methods of management. RECENT FINDINGS Advances in technology have enabled clinicians to better understand the connection between brain and laryngeal function and dysfunction. Refinements in imaging and genetic investigation tec...

Coprevalence of tremor with spasmodic dysphonia: a case-control study.

OBJECTIVES/HYPOTHESIS The aim of this study was to define the coprevalence of tremor with spasmodic dysphonia (SD). STUDY DESIGN A single-institution, prospective, case-control study was performed from May 2010 to July 2010. METHODS Consecutive patients with SD (cases) and other voice disorders (controls) were enrolled prospectively. Each participant underwent a voice evaluation and an eval...
