“…For the natural sitting position, the participants (young adult group only) were asked to sit naturally in the chair, with their arms naturally placed on the table, and their gaze horizontally on the camera in front. Using external markers in combination with digital photographs has been proved to be reliable and valid in postural evaluation [ 18 – 20 ] and has been utilized in our previous studies [ 21 ]. The method of taking photographs for spine angle analysis, as a part of the noninvasive whole-body posture assessment, can help avoid radiographic exposure [ 22 ].…”

Effects of a postural cueing for head and neck posture on lumbar lordosis angles in healthy young and older adults: a preliminary study

et al. 2022

Background Postural rehabilitation plays an important role in the treatment of non-specific low back pain. Although pelvic inclination has been widely used to improve lumbar lordosis, the effect of cervical anterior inclination on lumbar lordosis in young and older adults in sitting and standing posture is still unclear. This preliminary study was designed to examine the influence of changing the cervical anterior angle on the lumbar lordosis angle, through alterations of the head position under the natural sitting and standing conditions, aiming to provide a basis for establishing a new postural rehabilitation strategy. Methods Thirty-six young (24.0 ± 2.2 years, 14 females and 22 males) and 38 older (68.4 ± 5.9 years, 36 females and 2 males) healthy adults participated in this study. The four spinal regional angles—cervical anterior angle, thoracic kyphosis angle, lumbar lordosis angle, and pelvic forward inclination angle, were measured in standing and relaxed sitting postures to determine the effects of a postural cueing for the head and neck posture, “inclining head backward and performing chin tuck,” on lumbar lordosis angle. Results In the standing posture, the pelvic forward inclination angle in the older adult group was significantly smaller (P < 0.001, by ANOVA) than that in the young adult group and increased significantly (P < 0.001) in response to the postural cueing. In addition, the thoracic kyphosis angle in the standing (P = 0.001) and sitting (P = 0.003) positions was significantly reduced in response to the postural cueing. However, the lumbar lordosis angle in response to the postural cueing increased significantly in both the standing position (P < 0.001) and sitting position (P < 0.001). Conclusion The results suggest that increasing the cervical anterior angle can increase the lumbar lordosis angle, and the cervical anterior inclination can be used as an alternative to pelvic forward inclination to improve the lumbar lordosis angle. Furthermore, the change in head and neck posture can reduce the thoracic kyphosis angle, making it possible to establish a new noninvasive body posture rehabilitation strategy.

“…For the natural sitting position, the participants (young adult group only) were asked to sit naturally in the chair as they used in school. Using external markers in combination with digital photographs has proved to be reliable and valid in postural evaluation [15][16][17]. In addition, the method of taking photographs for spine angle analysis, as a part of the non-invasive whole body posture assessment, can help avoid radiographic exposure [18], replacing methods that are expensive and having health risks [19].…”

This preliminary study was designed to examine the influence of changing the cervical anterior angle on the lumbar lordosis angle, through alterations of the head position under the natural sitting and standing conditions, aiming to provide a basis for establishing a new postural rehabilitation strategy.Methods Thirty-eight older (68.4 ± 5.9 years old) and 36 young (24.0 ± 2.2 years old) healthy adults participated in this study. The four spinal regional angles - cervical anterior angle, thoracic kyphosis angle, lumbar lordosis angle, and pelvic foreword inclination angle were measured in standing and relaxed sitting postures to determine the effects of a postural cueing, “inclining head backward and performing chin tuck”, for the head and neck posture on lumbar lordosis angle.Results In the standing posture, the pelvic foreword inclination angle in the older group was significantly smaller (P <0.001) than that in the young group, and increased significantly (P <0.001) post the postural cueing. In addition, the thoracic kyphosis angle in the standing (P = 0.001) and sitting (P = 0.003) positions was significantly reduced post the postural cueing. However, the lumbar lordosis angle post postural cueing increased significantly in both the standing position (P <0.001) and sitting position (P <0.001).Conclusion The results suggest that increasing the cervical anterior angle can indeed increase the lumbar lordosis angle, and the cervical anterior inclination can be used as an alternative to pelvic foreward inclination to improve the lumbar lordosis angle. Furthermore, the change of head and neck posture can reduce the thoracic kyphosis angle, making it possible to establish a new non-invasive body posture rehabilitation strategy.(approval number TJUS2019032)

Os protetores bucais são dispositivos intraorais que visam prevenir traumatismos dentários e maxilofaciais decorrentes da prática esportiva. Por ser um dispositivo interoclusal, é necessário entender e saber se este pode interferir no equilíbrio corporal do atleta, tendo em vista que a existência da relação entre o sistema temporomandibular e o controle postural já foi comprovada analisando diferentes oclusões dentarias e posições mandibulares. O objetivo deste estudo foi avaliar a influência do protetor bucal individualizado (PBI) no equilíbrio e postura corporal como também extrair seu relato da percepção do uso quanto a possíveis alterações no equilíbrio, postura corporal podendo interferir no desempenho esportivo. Este estudo é um ensaio clínico não randomizado que incluiu 65 atletas atendidos por demanda espontânea no ambulatório de Odontologia do Esporte da Faculdade de Odontologia da Universidade de São Paulo (FOUSP). A utilização do PBI teve influência significante na variável distancia glabela mento (p=0,005). Em relação ao relato da percepção de uso, 75,68% relataram alterações no equilíbrio e 70,28% na postura corporal, 70,28% relataram melhora de desempenho e 67,56% melhora no gesto esportivo. Conclui-se que utilização do PBI causa mais confiança nos atletas na execução dos exercícios e consequentemente, no desempenho esportivo.
