Voice change after Neuromuscular Electrical Stimulation to laryngeal muscles
نویسندگان
چکیده
This study investigated the effect of Neuromuscular Electrical Stimulation (NMES) on the loudness, pitch and quality of the voice of the males diagnosed with dysphagia by stroke. NMES was conducted on experimental group of 15 patients for 2 month repeatedly while compensatory strategies for dysphagia were performed on control group of 15 patients. As the result of analysis of covariance (ANCOVA), NMES and compensatory strategies had significant difference in intensity, jitter and shimmer (p<0.05) while they did not in pitch and NNE. After the intervention of NMES, voice loudness of the subjects was enhanced and periodicity of vocal cord vibration (Jitter, Shimmer) was stabilized.

Electrical Stimulation of the Suprahyoid Muscles in Brain-injured Patients with Dysphagia: A Pilot Study
OBJECTIVE To investigate the therapeutic effects of repetitive electrical stimulation of the suprahyoid muscles in brain-injured patients with dysphagia. METHOD Twenty-eight brain-injured patients who showed reduced laryngeal elevation and supraglottic penetration or subglottic aspiration during a videofluoroscopic swallowing study (VFSS) were selected. The patients received either convention...
متن کاملNeuromuscular induced phonation in a human ex vivo perfused larynx preparation.
Considering differences in laryngeal anatomy, degree of control, and range of voice qualities between animals and humans, investigations of the neuromuscular process of voice control are better conducted using a living human larynx in which parametric stimulation of individual laryngeal muscles is possible. Due to difficulties in access and monitoring of laryngeal muscle activities, such invest...
متن کاملAcoustic Analysis of Voice Change in Normal Speakers Following Transcutaneous Electrical Stimulation to the Laryngeal Area
Transcutaneous electrical stimulation (TES) is being used more frequently by speech-language pathologists to treat individuals with dysphagia since the advent of VitalStim ® . Anecdotal reports suggest changes in voice quality associated with TES. This study was completed to examine acoustic measures of voice change in normal speakers following TES. Thirty speakers with normal voices, ages 19-5...
متن کاملFunctional and morphological evidence of age-related denervation in rat laryngeal muscles.
Laryngeal muscle dysfunction compromises voice, swallowing, and airway protection in elderly adults. Laryngeal muscles and their motor neurons and their motor neurons communicate via the neuromuscular junction (NMJ). We tested the hypothesis that aging disrupts NMJ organization and function in the laryngeal thyroarytenoid (TA) and posterior cricoarytenoid (PCA) muscles We determined NMJ density...
متن کاملLaryngeal Electromyography: Basic Concepts and Clinical Uses
Laryngeal electromyography (LEMG) is a procedure that evaluates the integrity of the muscular and nervous systems of the larynx. This test is performed on patients who have evidence of a movement disorder of the vocal folds. The purpose of the LEMG is to help the physician diagnose and differentiate the causes of these movement disorders. There are several different types of problems that can r...
