Introduction: Infrared thermography has the potential to help assess human head and neck muscles, as thermal variation measurements due to muscle imbalance can contribute to the evaluation and therapeutic follow-up of various clinical conditions in the field of health.
Objective: This study investigated, with a scoping review, the use of infrared thermography in complementary assessments of human head and neck muscles to determine the extent of research on the topic, what methodologies are used in thermal assessment and thermographic analysis, what regions are assessed, and what results are expected in thermography.
Methods: LILACS, MEDLINE, SciELO, and Web of Science were the databases searched to identify articles published on the topic, with no restriction of language or time of publication.

Acoustic analysis of the vocal signal; 3. Voice self-assessment; 4.
View Article and Find Full Text PDFPurpose: Linear acoustic indices are significantly influenced by speaking voice intensity. The main aim of this work was to compare acoustic measures based on linear and nonlinear models in different speaking voice intensity levels and to analyze the reliability of those measures in different intensity levels in subjects with voice disorders.
Methods: 435 samples from subjects (314 women, 121 men with a mean age of 41.
Objectives: The aim of this study was to review systematically the literature and to investigate the effects of electrical stimulation in treating dysphonia.
Study Design: This is a systematic review.
Methods: The publications indexed on the MEDLINE, LILACS, PubMed, Web of Science, and SciELO databases were searched.
Purpose: This study aimed to investigate the effect of transcutaneous electrical nerve stimulation (TENS) associated with vocal therapy in women with behavioral dysphonia.
Method: Seventeen women with behavioral dysphonia were divided into an experimental group (n = 8) and a placebo group (n = 9). All were submitted to six sessions of vocal therapy, according to the Comprehensive Voice Rehabilitation Program.
Objective: To verify the immediate effects of voiced gargling on the electrical activity of extrinsic laryngeal muscles and vocal self-assessment.
Methods: A sample of 20 individuals of both sexes, mean age of 31.95 (±11.
Introduction: There is evidence that all the complex machinery involved in speech acts along with the auditory system, and their adjustments can be altered.
Objective: To present the evidence of biofeedback application for treatment of vocal disorders, emphasizing the muscle tension dysphonia.
Methods: A systematic review was conducted in Scielo, Lilacs, PubMed and Web of Sciences databases, using the combination of descriptors, and admitting as inclusion criteria: articles published in journals with editorial committee, reporting cases or experimental or quasi-experimental research on the use of biofeedback in real time as additional source of treatment monitoring of muscle tension dysphonia or for vocal training.
Voice disorders can occur in the elderly as a result of natural anatomical and physiological changes or greater exposure to pathological conditions in the aging, affecting communication and quality of life. Nevertheless, data about the prevalence of voice disorders in this phase of life are not well known in a population-based perspective. The aim of the present systematic review was to identify the prevalence of vocal disorders in persons aged 60 years or more in population-based studies.

Hypothesis: Dysphonic individuals have higher electrical activity in the supra and infrahyoid muscles than those nondysphonic.
Study Design: Prospective, cross-sectional, case series study.
Purpose: The aim of the study was to compare the different parameters, regarding the peak and mean, at different phonatory tasks for standardization of electromyography signal of electrical activity (EA) of the laryngeal extrinsic muscles on voice evaluation.
Methods: The electrical potentials of the suprahyoid (SH) and infrahyoid (IH) muscles of 35 voluntary nondysphonic subjects were evaluated using three evaluations of rest, two maneuvers to determine maximum voluntary sustained activity (MVSA), and usual and strong intensity of vowel /ɛ/ and 20-30 count emissions. The EA signal was converted using root mean square in microvolts and normalized by mean and peak of each task.
Unlabelled: After total laryngectomy surgery, nasal airflow is moved permanently to the tracheostomy opening, compromising the contact of odorant molecules with the nasal cavity, which may reflect changes in the olfactory and gustatory perception in these individuals.
Objective: To evaluate the functions of smell and taste in total laryngectomized patients.
Study Design: a study of series.
Introduction: Surface electromyography has been used to assess the extrinsic laryngeal muscles during chewing and swallowing, but there have been few studies assessing these muscles during phonation.
Objective: To investigate the current state of knowledge regarding the use of surface electromyography for evaluation of the electrical activity of the extrinsic muscles of the larynx during phonation by means of an integrative review.
Method: We searched for articles and other papers in the PubMed, Medline/Bireme, and Scielo databases that were published between 1980 and 2012, by using the following descriptors: surface electromyography and voice, surface electromyography and phonation, and surface electromyography and dysphonia.
Purpose: To investigate which muscular maneuvers provide larger electric activity (EA) of the suprahyoid (SH) and infrahyoid (IH) muscles to be used as surface electromyography (SEMG) signal normalization reference.
Methods: The electrical potentials of the SH and IH muscles of 12 subjects were evaluated using six muscular maneuvers, involving the position of the tongue and effort. It was selected as maximum voluntary sustained activity maneuver, the one having the minor coefficient of variation and the smallest value for each muscle group.
Introduction: Among people affected by cancer, the impairment of quality of life of people affected by cancer can cause have devastating effects. The self-image of patients after post-laryngectomyzed patients may be find themselves compromised, affecting the quality of life in this population.
Objective: To characterize quality of life in related to communication in people who have undergone went total laryngectomy surgery.
Introduction: Total laryngectomy creates deglutition disorders and causes a decrease in quality of life Aim: To describe the impact of swallowing and quality of life of patients after total laryngectomy.
Method: A case series study. Patients completed a Swallowing and Quality of Life questionnaire composed of 44 questions assessing 11 domains related to quality of life (burden, eating duration, eating desire, frequency of symptoms, food selection, communication, fear, mental health, social functioning, sleep, and fatigue).
Unlabelled: Total laryngectomy is a surgical procedure that can change swallowing biomechanics, including muscle activity of the masseter; this muscle stabilizes the mandible.
Aim: To characterize the electrical activity of the masseter muscle during swallowing after total laryngectomy. Series study.

Unlabelled: Bulimia nervosa (BN) is a type of feeding disorder that starts in adolescence and presents a variety of symptoms, recurrent vomiting in the oral cavity that may reach down to the larynx - similarly to gastro-esophageal reflux, causing laryngeal and voice disorder alterations.
Aim: These studies aimed at surveying the literature and investigate the studies that considered BN a risk factor for voice disorders.
Results: of the ninety three papers we found, twenty-three were used as a basis for this review, among them, only three discuss BN as an etiology factor associated with voice changes in adult women, and we did not find any paper associating this with bulimic teenagers.
