-Photogrammetry is a valuable tool for the diagnosis and measurement of postural changes, but the lack of standardization of anatomical references and angular measures impairs the comparison between studies and compromises the reliability of the results. The objective of this study was to evaluate the inter-and intraexaminer reliability of angular measures proposed by the SAPO posture assessment software (v. 0.68). Twenty--four subjects were photographed in the standing position according to the recommendations of the SAPO software. Three examiners (A, B and C) experienced in the use of the software analyzed the images and repeated the analysis after 7 days. Variance, intraclass correlation coefficient (ICC), and t-test adopting a level of significance of 5% were applied. With respect to interexaminer reliability among the 20 angles measured, two were classified as unacceptable (A13: ICC = 0.623; A14: ICC = 0.568), one as acceptable (A19: ICC = 0.743), one as very good (A20: ICC = 0.860), and 16 as excellent (ICC ≥ 0.90). Evaluation of repeatability of the method by the same examiner showed that two angles measured by examiner A differed significantly between the two measurements (A11: p = 0.015; A12: p = 0.026), as did two angles measured by examiner B (A2: p = 0.019; A12: p = 0.015) and one angle measured by examiner C (A16, p = 0.011). In conclusion, comparison between different examiners showed that the angles proposed by the SAPO protocol are reliable for the measurement of body segments.

Objetivo: Descrever valores de Capacidade Vital Forçada (CVF), Pressão Inspiratória Máxima (PImáx) e Pressão Expiratória Máxima (PEmáx) em cantores profissionais populares de um município de interior de estado e compará-los com os valores preditos pela literatura. Métodos: Pesquisa quantitativa e retrospectiva, com 18 cantores profissionais populares, com média de idade de 36,6 anos. Foi medida a CVF por meio de espirômetro portátil digital e as pressões respiratórias máximas com manovacuômetro digital. Resultados: Não houve significância estatística entre os três grupos, quanto aos valores preditos, medidos e as diferenças de CVF. Quanto à Pimáx, apenas houve significância entre valores preditos e medidos no grupo de cantoras (p = 0,026); nos grupos masculinos não houve significância (p = 0,121; p = 0,715); e também não houve nas diferenças entre valores preditos e medidos. Nas PEmáx, não houve significância estatística entre valores preditos e medidos nos três grupos e nas diferenças entre os três grupos. Conclusão: A CVF e PEmáx se apresentaram dentro da normalidade prevista nos três grupos estudados, com exceção do grupo de cantoras, em que os valores medidos de PImáx foram menores do que os valores preditos.Palavras-chave: capacidade vital, pressões respiratórias máximas, cantores.

ResumoO objetivo deste estudo foi verificar e comparar as medidas vocais, respiratórias e da ativação do músculo transverso do abdome, antes e após um protocolo fisioterapêutico de treinamento intensivo da musculatura do centro de força corporal em uma profissional da voz. Participou uma jornalista, do sexo feminino, 21 anos de idade, sem queixa vocal. Relato de caso original, retrospectivo, aprovado pelo Comitê de Ética em Pesquisa (nº 40680614.7.0000.5346).2 Sonora modal, da extensão dinâmica e cantada, das pressões respiratórias máximas, da capacidade vital forçada e da ativação do músculo transverso do abdome, por meio do esfigmomanômetro com unidade de biofeedback pressórico. Após, foi aplicado um protocolo fisioterapêutico de treinamento intensivo do centro de força corporal e reavaliação. Houve aumento da sustentação das emissões, do Nível de Pressão Sonora modal e mínimo, da extensão cantada, das pressões respiratórias máximas e da ativação do transverso do abdome; e houve redução do Nível de Pressão Sonora máximo e da diferença entre a média das vogais e a contagem de números. Assim, o treinamento fisioterapêutico intensivo do centro de força corporal promoveu melhora do controle respiratório e da coordenação pneumofonoarticulatória.

Abstract The aim of this study was to verify and compare vocal, respiratory and transverse abdominal muscle activation measurements before and after a physiotherapeutic protocol for intensive training of the body force center musculature in a voice professional. A 21-year-old female journalist with no vocal complaint participated. Original, retrospective case report, approved by the Research Ethics Committee (nº 40680614.7.0000.5346). It was collected: sustained emission of /a/, /i/, /u/, /s/, /z/, /e/ and the counting of numbers in usual pitch and loudness, of /e/ voiceless, of Modal Sound Pressure, dynamic and sung extension, maximal respiratory pressures, forced vital capacity and transverse abdomen activation, by means of a sphygmomanometer with a pressure biofeedback unit. Afterwards, a physiotherapeutic protocol for intensive training of the body force center and reevaluation was applied.Emissions support, modal and minimum Sound Pressure Level, sung extension, maximal respiratory pressures and activation of the transverse abdomen increased; and there was a reduction in the maximum Sound Pressure Level and the difference between the vowel average and the number count. Thus, intensive physical therapy training at the body strength center improved respiratory control and pneumophonoarticulatory coordination.

Introduction: Education professionals are one of the most important occupational groups and represents one of the main parts of the economy of modern society. The vocal demands most mentioned by the teachers are talking while standing up, talking a lot and in a closed environment, which corresponds to the most frequent situations encountered in teaching. In addition, remaining in the standing position for a prolonged period may have repercussions on other systems and generate postural deviations, pain and reduced functionality. Objective: To verify changes in pressure pain threshold, in disability index and in craniocervical posture of female teachers with vocal and musculoskeletal complaints, and with normal larynx, after myofascial release - pompage. Methods: This study was a controlled and randomized clinical trial. The following procedures were performed: anamnesis, videolaryngoscopy, hearing screening, clinical and photogrammetric postural assessment using the SAPo® protocol, completion of the neck pain self-assessment protocol Neck Disability Index, and pain threshold in the cervical muscles using the Pain Pressure Threshold. Myofascial therapy with pompage had a total of 24 sessions of 40 min each, three times a week, in 28 teachers assigned to the study group (SG), and 28 to the control group (CG). Afterwards, the groups were reassessed. Results: The SG presented a significant improvement in the pain threshold of all the muscles evaluated, in the posture of most of the body segments evaluated, and in the cervical disability. In the CG there was a significant improvement in angle A2 after therapy. Conclusion: After myofascial release therapy with pompage, the subjects presented a reduction in cervical pain and in functional disability, an increase in pain threshold, and posture improvement.
