“…The more superior insertions of the UT and SA may make them more dependent on changes in the cervical, scapular, shoulder and rib cage posture, which are findings that were not demonstrated nor investigated in this study. For example, it has been demonstrated that stretching of the pectoralis minor may increase the activity of UT and SA during the execution of the scapular posterior tilt exercise, 28 suggesting a possible influence of a shortened/rigid pectoralis minor on the activity of these muscles. Future studies should investigate the effects of reduction of the pelvic anterior tilt on the posture of these segments, which may help to explain the lack of an effect of pelvic posture on SA and UT activity.…”

Background: Modifications of posture in a segment may influence the posture of adjacent and nonadjacent segments and muscular activity. The spine-shoulder and spine-pelvis relationships suggest that the pelvis may influence shoulder posture. Objective: To investigate the effect of the active reduction of the anterior pelvic tilt on shoulder and trunk posture during static standing posture and on the electromyographic activity of the scapular upward rotators during elevation and lowering of the arm. Methods: Thirty-one young adults were assessed in a relaxed standing position and a standing position with 30% active reduction of the anterior pelvic tilt. The pelvic tilt, trunk posture, and forward shoulder posture during the static standing posture and the electromyographic activity during elevation and lowering of the arm were assessed. Results: Paired t-tests indicated that the active reduction of the anterior pelvic tilt reduced the trunk extension (MD = 1.09; 95%CI = −2.79 to −1.03). There were no effects on the forward shoulder posture (MD = 0.09; 95%CI = −0.92 to 1.09). Repeated measures of analyses of variance indicated an increase in lower trapezius electromyographic activity (MD = 3.6; 95%CI = 1.28 to 5.92). There was a greater reduction in upper trapezius activity after pelvic tilt reduction during arm elevation (MD = 1.52%; 95%CI = −2.79 to −0.25) compared to that during the lowering phase. There were no effects of pelvic tilt reduction on the electromyographic activity of the serratus anterior (MD = 3.26; 95%CI = −3.36 to 9.87).

“…There are discrepancies in the literature regarding the measurement of the PM muscle length, which include participant positioning and the position of the scapula when PM length is measured (Borstad & Ludewig 2005 ; Ko et al 2016 ; Morais & Cruz 2016 ; Struyf et al 2012 ). In these studies, participants were positioned either in standing or in supine (Borstad 2006 , 2008 ; Borstad & Ludewig 2005 ; Cools et al 2010 ; Finley et al 2017 ; Ko et al 2016 ; Lee et al 2015 ; Mackenzie et al 2015 ; Rosa et al 2016 , 2017 ; Struyf et al 2012 , 2014 ). In studies where PM length was measured in standing, the scapula could be in an anteriorly tilted position because of the influence of gravity on posture, thus demonstrating poor diagnostic accuracy and may provide inaccurate values for PM muscle length (Borstad 2006 , 2008 ; Borstad & Ludewig 2005 ; Finley et al 2017 ; Ko et al 2016 ; Lee et al 2015 ; Rosa et al 2016 , 2017 ).…”

“…The position of the scapula is important when measuring the PM length. In several studies, the PM length is measured with the scapula in the resting position (Borstad 2006 , 2008 ; Borstad & Ludewig 2005 ; Cools et al 2010 ; Lee et al 2015 ; Mackenzie et al 2015 ; Rosa et al 2016 ; Struyf et al 2012 , 2014 ). Rosa and colleagues ( 2017 ) argue that in the resting position of the scapula, the PM muscle is not in an optimal lengthened position and therefore added a measurement where the scapula is taken actively into a posteriorly tilted position.…”

Background: The pectoralis minor (PM) muscle is commonly regarded as a contributor to abnormal scapula positioning. Subsequently, the muscle length of the scapular stabilising muscles may be affected, as these muscles assume a lengthened position, which over time causes weakness. There are inconsistencies regarding PM muscle length values because of the different techniques and positions used when the length of the PM muscle is measured.Objective: To determine the PM muscle length in participants aged 18−24 using a Vernier® caliper and expressed as pectoralis minor index (PMI), with the scapula in three different positions.Method: The PM muscle length of 144 participants was measured with a Vernier® caliper (intraclass correlation coefficient 0.83−0.87). Measurements were made with the scapula in the resting position, in an active and a passive posterior tilt position.Results: Significant differences were observed in PMI between the resting scapula position – 10.04 (confidence interval, CI 9.93–10.14) and active posterior tilt – 10.19 (CI 10.09–10.30) (p 0.001); the resting position – 10.04 (CI 9.93–10.14) and passive posterior tilt – 10.77 (10.66–10.87) (p 0.001) and active – 10.19 (CI 10.09–10.30) and passive posterior tilt 10.77 (10.66–10.87) (p 0.001). The dominant side had lower PMI values than the non-dominant side.Conclusion: The significant differences between the active and posterior tilt positions suggested that optimal muscle length of PM was affected by the inner range strength of the lower fibres of Trapezius.Clinical implications: It is important that in clinical practice not only the length of PM in scapular misalignment but also the strength of the antagonistic muscles is considered.

“…Maus hábitos na infância e na adolescência repercutem em problemas posturais nos jovens como escoliose, desalinhamento escapular [3,4], queixas álgicas na região dos ombros, pescoço e lombar [5]. O uso inadequado de celulares, tabletes e mochilas também podem contribuir para tais desalinhamentos [5].…”

O exercício físico juntamente com cuidados ergonômicos tem sido um dos fatores determinantes para uma boa postura. O treinamento físico militar resulta (TFM) em melhora na resistência cardiorrespiratória, na força muscular e diminuição de peso. No entanto, pouco tem sido investigado sobre o efeito do TFM na postura de recrutas. O objetivo do estudo foi avaliar as adaptações posturais de recrutados submetidos ao treinamento físico e a rotina do serviço militar obrigatório ao longo de um ano. Foram avaliados 61 jovens saudáveis do sexo masculino em janeiro, junho e setembro. Avaliações antropométricas, de fotogrametria e o Questionário Nórdico de Sintomas Osteomuscular ocorreram no início, meio e final do período do TFM. Foram analisados 21 pontos anatômicos nas visões anterior, posterior e lateral direita. Os resultados mostraram mudanças mais importantes na simetria postural dos recrutas na visão lateral direita. Conclui-se que o TFM tem importância substancial para produzir mudanças positivas na postura dos recrutas ao longo de um ano praticando exercícios físicos diários.Palavras-chave: treinamento físico militar, postura, exercício.
