Musculoskeletal stress syndrome, extrinsic laryngeal muscles and body posture: theoretical considerations

The theme of this study is the musculoskeletal stress syndrome, extrinsic laryngeal muscles and body posture. The purpose is to describe, from the literature review, the characteristics of the extrinsic muscles of the larynx; posture; vocal implications of musculoskeletal stress syndrome; evaluation and physical therapy and voice therapy. We performed a literature review of the last 13 years which included articles aimed and/or body textwere in line with the objectives of this study. The research was conducted in the databases of Literatura Latino-Americana e do Caribe em Ciências da Saúde, Biblioteca Regional de Medicina, Public Medline, Medical Literature Analysis and Retrieval System on Line, Scientific Electronic Library Online and Google Schoolar. Were established important relationships within the physical therapy and voice therapy, among which stand out the relationships muscular, postural and functional synergy in the vocal apparatus. In physical therapy to reduce muscle tension, the literature indicates use of transcutaneous electrical stimulation, low level laser, laser acupuncture, cryotherapy, manual therapy and traction, massage, cervical manipulations and mobilizations, associated or not to exercise, stretching, isometric relaxation , assisted soft tissue mobilization, therapeutic exercises aimed at correcting balance and muscle, diaphragm and respiratory rehabilitation therapy craniocervical flexion. In speech therapy, studies found only through digital manipulation of the larynx and semi-ocluded vocal tract exercises.
