The goal of this research was to train a self-organizing map (SOM) on various acoustic measures (amplitude perturbation quotient, degree of voice breaks, rahmonic amplitude, soft phonation index, standard deviation of the fundamental frequency, and peak amplitude variation) of the sustained vowel /a/ to enhance visualization of the multidimensional nonlinear regularities inherent in the input d...
We aimed to study the attitude of Italian neurologists in use conventional MRI patients with idiopathic adult-onset focal dystonia. Patients were included Dystonia Registry by experts working different centers. was available for 1045 1471 (71%) analysis. Using logistic regression analysis, we found that more likely be performed cervical dystonia, spasmodic dysphonia, or non-task-specific upper ...
Background: Symptoms of spasmodic dysphonia (SD) are usually managed successfully with botulinum toxin injections. Vocal tremor (VT), which accompanies SD, has a poor response to this treatment. Case Report: We report a case of a female with SD and VT who became symptom-free for 10 months after the intake of a single dose of sodium oxybate (XyremH). The long-term treatment effect correlated wit...
Objectives: Objective and subjective evaluation of botulinum neurotoxin A (BoNTA) treatment for adductor type spasmodic dysphonia is presented. Therefore, a combinatorial approach based on patients’ and speech experts’ assessment of voice impairment, as well as on the acoustic analysis of spoken standardized text was performed. Study design: Prospective clinical study. Materials and methods: Fo...
Intralaryngeal injections of botulinum toxin (Botox), under electromyographic guidance, have emerged as an effective treatment for adductor spasmodic dysphonia. To remain effective, these injections must be repeated every 3 to 9 months as the symptoms recur. One drawback to the current method is the need for electromyographic confirmation of needle placement into the thyroarytenoid muscle. This...
OBJECTIVE To review the safety of simultaneous bilateral posterior cricoarytenoid muscle botulinum toxin injections. DESIGN Retrospective case series review. SETTING Tertiary care academic clinic. PATIENTS Twenty-one patients with abductor spasmodic dysphonia. INTERVENTIONS Patients received 100 simultaneous bilateral posterior cricoarytenoid muscle botulinum toxin injections for isolat...
OBJECTIVES/HYPOTHESIS To assess the comparative effectiveness of botulinum toxin and propranolol in patients with essential vocal tremor (EVT). STUDY DESIGN Individual prospective cohort study. METHODS Study patients were recruited at the Emory Voice Center from patients seeking treatment for EVT. Exclusion criteria included current β-blocker treatment, spasmodic dysphonia, or other disease...
PURPOSE Spasmodic dysphonia (SD) is a rare but often debilitating disease. Due to lack of awareness among practitioners and lack of well-defined diagnostic criteria, it can be difficult for patients with SD to receive a diagnosis and subsequent treatment. There is currently no literature documenting the efficacy of the medical community in recognizing and diagnosing this disorder. We aimed to q...
OBJECTIVE A study was undertaken to identify the gene underlying DYT4 dystonia, a dominantly inherited form of spasmodic dysphonia combined with other focal or generalized dystonia and a characteristic facies and body habitus, in an Australian family. METHODS Genome-wide linkage analysis was carried out in 14 family members followed by genome sequencing in 2 individuals. The index patient und...
Objective The basal ganglia are a group of structures that act as a cohesive functional unit. They are situated at the base of the forebrain and are strongly connected with the cerebral cortex and thalamus. Some speech disorders such as stuttering can resulted from disturbances in the circuits between the basal ganglia and the language motor area of the cerebral cortex. Stuttering consists of b...
