“…In singers, changes in a number of acoustic parameters-including jitter, shimmer, fundamental frequency, and voice SPL-were explained with a better production and control of vocal fold tonus 18,19,44,45 . There were significant differences between profession groups in subjectively loud phonations, which supports this hypothesis.…”

“…This might lead to a stiffer and stabilized vocal fold, thereby reducing random variability in vocal fold vibratory patterns 34 . Further, as discussed above, it has been proposed that training effects may lead to better production and control of vocal fold tonus 18,19,44,45 . In that view, the significant influence of professional voice use level-hence, formal versus non-formal voice training-supports this proposed hypothesis.…”

OBJECTIVE: In vocally healthy children and adults, speaking voice loudness differences can significantly confound acoustic perturbation measurements. This study examines the effects of voice sound pressure level (SPL) on jitter, shimmer, and harmonics-to-noise ratio (HNR) in adults with voice disorders and a control group with normal vocal status. STUDY DESIGN: This is a matched case-control study. METHODS: We assessed 58 adult female voice patients matched according to approximate age and occupation with 58 vocally healthy women. Diagnoses included vocal fold nodules (n = 39, 67.2%), polyps (n = 5, 8.6%), and muscle tension dysphonia (n = 14, 24.1%). All participants sustained the vowel /a/ at soft, comfortable, and loud phonation levels. Acoustic voice SPL, jitter, shimmer, and HNR were computed using Praat. The effects of loudness condition, voice SPL, pathology, differential diagnosis, age, and professional voice use level on acoustic perturbation measures were assessed using linear mixed models and Wilcoxon signed rank tests. RESULTS: In both patient and normative control groups, increasing voice SPL correlated significantly (P < 0.001) with decreased jitter and shimmer, and increased HNR. Voice pathology and differential diagnosis were not linked to systematically higher jitter and shimmer. HNR levels, however, were statistically higher in the patient group than in the control group at comfortable phonation levels. Professional voice use level had a significant effect (P < 0.05) on jitter, shimmer, and HNR. CONCLUSIONS: The clinical value of acoustic jitter, shimmer, and HNR may be limited if speaking voice SPL and professional voice use level effects are not controlled for. Future studies are warranted to investigate whether perturbation measures are useful clinical outcome metrics when controlling for these effects. Study Design: Matched case-control study Methods: 58 adult female voice patients, matched according to approximate age and occupation with 58 vocally healthy women, were assessed. Diagnoses included vocal fold nodules (n:39, 67.2%), polyps (n:5, 8.6%), and muscle tension dysphonia (MTD; n:14, 24.1%). All participants sustained the vowel /a/ at soft, comfortable, and loud phonation levels. Acoustic voice SPL, jitter, shimmer, and HNR were computed using Praat. The effects of loudness condition, voice SPL, pathology, differential diagnosis, age, and professional voice use level on acoustic perturbation measures were assessed using linear mixed models and Wilcoxon signed-rank tests.Results: In both patient and normative control groups, increasing voice SPL correlated significantly (p<0.001) with decreased jitter and shimmer, and increased HNR.

“…Two sets of each period were performed for five minutes, two times per day, preferably in the morning and in the evening, during five weeks. After the therapeutic program, the CG presented a significant reduction in vocal roughness, an increase of TMF, jitter and shimmer reductions, an increase of harmonic-noise ratio and it was noted positive effect of the therapeutic program on voice 17 .…”

“…The literature that was consulted during the period from 2004 to 2014 showed only 11 research on vocal phonotherapy in healthy elderly people: one through vocal orientation 9 ; three with specific vocal exercises, such as, TMF support of vowels and musical scales with vowels and words 18 , sounded blowing 5 and the Finnish method of resonance tubes 22 ; two carried out a review of medical records of elderly who underwent voice therapy for presbyphonia, regardless of the kind of intervention 23,24 ; five of them applied therapeutic programs: the Lee Silverman 20 method, the Vocal Cognitive Program 21 , the program of vocal function exercises of Stemple 16,17 , and the comparison between the vocal function method and the PhoRTE 19 . The results of speech therapy with elderly people showed an improvement in voice quality in relation to the aspects of roughness 17,22 , breathiness 20,22 , asthenia 20,22 , instability 22 , tension 22 , loudness 20,21 and the general level of the vocal disorder 15,18,20,21,22,24 ; a decrease in effort phonation 18 , an improvement in resonance 18 and articulation clarity 21 . There was also verified an improvement of acoustic measures, reducing jitter 17,20,21 e shimmer 17,20 , an improvement in harmonic-noise ratio 17,20,21 and f0 20,21 .…”

“…Therapy programs that consist of vocal exercises have been proposed for favoring the glottal closure, increasing subglottic and sound pressure, producing normotensive voice, as well as stabilizing vocal quality and f0, besides providing an improvement in pneumo-phono-articulatory coordination and vocal strength 3,10,11,[15][16][17][18] .

This study is subject to vocal therapy and breathing physical therapy in the healthy elderly. The aim of this study was to review the literature on vocal therapy and respiratory therapy in healthy elderly. It was done a literature review of articles published between 2004 and 2014 in the databases Lilacs, Bireme, MedLine, PubMed and Scielo. Descriptors used: physical therapy specialty; breathing; speech therapy; aged; therapeutics and voice. The literature on vocal therapy with healthy elderly showed that the interventions have been made through vocal hygiene; traditional vocal therapy for the presbyphonia, regardless of the type of intervention; specific vocal exercises; and standardized treatment programs, there is evidence of improvement of the measures vocals perceptual-auditory, acoustic, self-assessment and laryngeal image. As for respiratory therapy, the literature showed that the techniques or procedures used whit healthy elderly were: used of Thershould machine, manual therapy techniques, incentive spirometry, respiratory exercises associated with the movement of the trunk and lower extremities and physical activity in general, with evidence of improvement in respiratory muscle strength, lung functional and functional autonomy of the elderly. Keywords: Physiotherapy; Speech Therapy; Aged; Breathing; Therapeutics; Voice RESUMO Este estudo tem como tema a fonoterapia vocal e a fisioterapia respiratória no idoso saudável. O objetivo do presente estudo foi revisar a literatura sobre fonoterapia vocal e sobre fisioterapia respiratória com idosos saudáveis. Foi realizado um levantamento bibliográfico de artigos publicados entre 2004 e 2014 nas bases de dados Lilacs, Bireme, MedLine, PubMed e Scielo. Descritores utilizados: physical therapy specialty; breathing; speech therapy; aged; therapeutics e voice. A literatura sobre fonoterapia vocal com idosos saudáveis mostrou que as intervenções têm sido feitas por meio de orientação vocal; terapia vocal tradicional para presbifonia, independente do tipo de intervenção; exercícios vocais específicos; e programas terapêuticos padronizados, havendo evidências de melhora de medidas vocais perceptivoauditivas, acústicas, de autoavaliação vocal e de imagem laríngea. Quanto à fisioterapia respiratória, a literatura evidenciou que as técnicas ou procedimentos utilizados com idosos saudáveis foram: uso do aparelho Threshold, técnicas de terapia manual, espirometria de incentivo, exercícios respiratórios associados ao movimento do tronco e membros inferiores e atividade física em geral, apresentando evidências de melhora na força muscular respiratória, função pulmonar e autonomia funcional dos idosos.
