“…Due to discrete nature of the raw data (i.e., obtained from medical imaging) and the small ranges of motion of the costovertebral joints (Beyer et al, 2014), it has been supposed in this paper that MHA orientation and position could have been ill-determined as described in a previous paper (De Lange et al, 1990).…”

“…Due to the number of degrees of freedoms (DoFs) of the thorax that includes many joints, costovertebral joint (CVJ) kinematic analysis at a specific level is difficult. Previous in vivo CVJ kinematic analysis proposed a method based on medical imaging (i.e., 3D modelling) and mean helical axis (MHA) computation (Beyer et al, 2014(Beyer et al, , 2013. Thorax medical imaging in 3 different positions Gauthier et al, 1994;Pettiaux et al, 1997) previously allowed estimation of local kinematic impairments of CVJ complexes (Beyer et al, 2014); this previous work recognized to be limited by the influence of small range-of-motions (RoM) on the helical axis determination (De Lange et al, 1990) and by the reduced amount of available discrete positions (i.e., 3).…”

“…In the literature review for this article, only one study was found that investigated in vivo, intact, thoracic ring biomechanics during one task, breathing. 16 In vivo spiral computed tomography was used to determine the 3D motion of the ribs and related vertebrae at full inhalation, full exhalation and a point somewhere in-between. This study confirmed that ribs one to seven posteriorly rotate in full inhalation and anteriorly rotate in full exhalation The mean helical axis for anterior and posterior rotation of the ribs was not oriented along the neck of the rib as previously described.…”

Understanding the biomechanics of the thorax is critical for understanding its role in multiple conditions since the thorax is part of many integrated systems including the musculoskeletal, respiratory, cardiac, digestive and urogynecological. The thorax is also an integrated system within itself and an element of the whole body/person. Therefore, understanding the biomechanics of the thorax is fundamental to all forms of treatment for multiple conditions. The interpretation of movement examination findings depends on one's view of optimal biomechanics and the influential factors. This article will provide a synopsis of the current state of research evidence as well as observations from clinical experience pertaining to the biomechanics of the thorax in order to help clinicians organise this knowledge and facilitate evidencebased and informed management of the, often complex, patient with or without thoracic pain and impairment. The integrated systems model (ISM) will be introduced as a way to determine when the noted biomechanical findings are relevant to a patient's clinical presentation.

Objectives: Lower thoracic widths and curvatures track upper pelvic widths and iliac blades curvatures in hominins and other primates (torso integration hypothesis). However, recent studies suggest that sexual dimorphism could challenge this assumption in Homo sapiens. We test the torso integration hypothesis in two modern human populations, both considering and excluding the effect of sexual dimorphism. We further assess covariation patterns between different thoracic and pelvic levels, and we explore the allometric effects on torso shape variation. Material and Methods: A sex‐balanced sample of 50 anatomically connected torsos (25 Mediterraneans, 25 Sub‐Saharan Africans) was segmented from computed tomography scans. We compared the maximum medio‐lateral width at seventh–ninth rib levels with pelvic bi‐iliac breadth in males and females within both populations. We measured 1,030 (semi)landmarks on 3D torso models, and torso shape variation, mean size and shape comparisons, thoraco‐pelvic covariation and allometric effects were quantified through 3D geometric morphometrics. Results: Females show narrow thoraces and wide pelves and males show wide thoraces and narrow pelves, although this trend is more evident in Mediterraneans than in Sub‐Saharans. Equal thoracic and pelvic widths, depths and curvatures were found in absence of sexual dimorphism. The highest strength of covariation was found between the lowest rib levels and the ilia, and allometric analyses showed that smaller torsos were wider than larger torsos. Conclusions: This is the first study testing statistically the torso integration hypothesis in anatomically connected torsos. We propose a new and more complex torso integration model in H. sapiens with sexual dimorphism leading to different thoracic and pelvic widths and curvatures. These findings have important implications in hominin body shape reconstructions.
