Corpo e voz: relação entre postura corporal inadequada e suas implicações na voz

Abstract

ABSTRACT

Introduction: The proper body posture provides better functioning of body structures and systems. The speech therapist must observe the balance between the respirato- ry and stomatognathic systems and the functions performed by them, as possible postural changes can impact voice production and, consequently, the vocal quality. Objective: To investigate the influence of body posture on structures associated with phonation and, consequently, its implications for vocal production. Method: A re- search was carried out using the technique of integrative literature review. The search was performed in the Scielo and Scholar Google databases, selecting works published from 2004 to 2021. Original articles on body posture and voice were in- cluded. The exclusion criteria adopted were: articles published in a foreign language; the ones not attached in the cited databases and papers that dealt with subjects un- related to the topic. Conclusion: Disadjusted parameters can cause changes in the level of voice production, interfering with vocal quality, thus, the analysis of the arti- cles evidenced the existence of interrelations between body posture and vocal quali- ty. Therefore, more research is needed on the topic in order to raise awareness in the general population, especially those who use their voice professionally, about the association between voice and posture and the possible changes that an inadequate body posture can cause in the voice of the speaker.
