“…These results are in accordance with similar studies (for example by Aronson et al and others [20,21]) and confirm that increased laryngeal tension may trigger improper, elevated positioning of the larynx, and additionally cause muscle pain reactions in the neck and throat. The role of hyperfunction of neck muscles in the etiology of voice disorders was studied by Roy et al [22] who reported that excessive muscle tension in the larynx raised it toward the hyoid bone, which in turn adversely affected vocal quality and efficiency.…”

Background: The aim of this study has been to assess the larynx and soft tissue around the vocal tract in a group of people with healthy voice, and in a group of patients with occupational dysphonia using the new laryngeal manual therapy palpatory evaluation scale (LMTPE). Material and Methods: The examinations were performed in a study (dysphonic) group of professional voice users who had developed voice disorders (N = 51) and in the control group of normophonic subjects (N = 50). All the participants underwent perceptual voice assessment and examination by means of the LMTPE scale. Additionally, phoniatric examination including VHI (Voice Handicap Index) questionnaire, GRBAS (the Grade of hoarseness, Roughness, Breathiness, Asthenic, Strained) perceptual evaluation, maximum phonation time (MPT) measurement and videostroboscopy was performed in the study group. Results: The comparison of the LMTPE total score showed that the results of the study group were significantly poorer than those of controls (p < 0.001). In the study group, correlations were found between the LMTPE results and the VHI scores (p < 0.05), perceptual evaluation by the GRBAS (p < 0.05) and the objective parameter MPT (p < 0.05). Conclusions: The study has proven that the LMTPE scale is characterized by the high score of Cronbach's α ratio estimating the reliability of the test. The results have confirmed that the LMTPE scale seems to be a valuable tool, useful in diagnostics of occupational dysphonia, particularly of hyperfunction origin. Med Pr 2017;68(2):179-188

“…Other hypothesis is that the time of execution of the finger kazoo was not sufficient to present more evident results in women without complains. However, the auditory-perceptual assessment and the time variable have not been the focus of the studies about the subject (2,3,(5)(6)(7)10). New studies comparing the effects of the exercises depending on the execution time may clarify these issues.…”

“…Techniques as lip or tongue vibration, bilabial fricatives, labial constriction, prolonged "B" exercise, glottis hardening and tube phonation are considered ESOVT and facilitate source-philter interaction reducing the risks of vibration trauma. These exercises have been suggested in different situations: cases of vocal disorders, subjects with normal voices that whish clearer or sounder voices or to the vocal warmingup (2)(3)(4)(5).…”

“…Several authors studied the effects of ESOVT and reported, for example changes in the fundamental frequency (Fo) and positive changes in subjects with vocal cords mass lesions (2)(3)(4)(5)(6)(7)(8)(9)(10). However the effects of these exercises are still slightly known since the focus of the studies have been the use of computerized models and observation only during the performance of the exercises.…”

TEMA: efeitos imediatos de dois exercícios de trato vocal semi-ocluído. OBJETIVO: verificar e comparar os efeitos imediatos dos exercícios finger kazoo (FK) e fonação com canudo (FC). MÉTODO: vinte e três mulheres sem queixa vocal e idades entre vinte e três e quarenta anos executaram os exercícios duas vezes, em ordem pré-estabelecida (FK - FC - FC - FK), e realizaram uma auto-avaliação vocal após cada um deles. Amostras da vogal sustentada [e] e da fala (contagem um-dez) foram coletadas pré e pós-exercícios, para a avaliação perceptivo-auditiva, realizada por duas fonoaudiólogas treinadas, e para a análise acústica. RESULTADOS: na auto-avaliação os efeitos positivos (FK 122 - 77,7% e FC 118 - 74,7%) foram mais relatados que os negativos, sendo os principais: voz mais clara (FK 33 - 21% e FC 29 - 18,4%), forte (FK 24 - 15,3% e FC 26 - 16,5%) e fala mais fácil (FK 29 - 18,5% e FC 30 - 19%). Na avaliação perceptivo-auditiva, um maior número de emissões foram consideradas melhores pós-fonação com canudo, tanto na vogal (22 - 47,8% pós e 19 - 41,3% pré-exercício), quanto na fala (24 - 52,2% pós e 15 - 32,6% pré), enquanto um maior número de emissões foram consideradas melhores pré-finger kazoo, tanto na vogal (18 - 39,1% pré e 17 - 37% pós), quanto na fala (21 - 45,6% pré e 17 - 37% pós). Na avaliação acústica, foi observada redução da freqüência fundamental após ambos os exercícios (FK 6,47Hz, e FC 5,52Hz). CONCLUSÃO: os exercícios finger kazoo e fonação com canudo produziram relatos positivos e semelhantes na auto-avaliação vocal e resultados semelhantes na análise acústica, enquanto a avaliação perceptivo-auditiva indicou efeitos positivos apenas na fonação com canudo.

Purpose: To identify the immediate effects of voiced vibration and vocal fry exercises on healthy subjects by means of acoustic parameters and high-speed kymography. Methods: Thirty healthy subjects (18 women and 12 men, aged from 19 to 45 years old) participated in this study. The voices were recorded at the range of 44.100 samples/second, before and after of the vocal exercises. We developed a computational routine to extract jitter and shimmer. High-speed kymography was generated from laryngeal images for the analysis of the phase times: closed (CPh), open (OPh), of closing (cPh) and of opening (oPh) and used the paired t-Student test and the Mann-Whitney test, with a significance level of 0.05. Results: After voiced vibrations, acoustic parameters showed reduced jitter for both genders (p=0.018 for men and p<0.01 for women) and reduced shimmer for female voices (p<0.01). There was a decrease in CPh (p=0.046) and cPh (p=0.026) and an increase in OPh (p=0.05) in female vocal folds. After vocal fry, we identified decreased jitter (p<0.01) in female voices and cPh (p=0.026) in male vocal folds. Conclusion: We observed more positive immediate effects of the voiced vibrations, mainly in voice quality and vocal folds among females. Nevertheless, studies with larger male sample and investigation of the appropriate time of vocal fry are necessary to confirm the results of this search.
