Stand up straight! : a history of posture
Our bodies change over time; posture is ambiguous in a number of cultural and disciplinary realms. Your posture can denote you as healthy or ill, elegant or slovenly, beautiful or ugly. Gilman examines the history and sociology of posture: how society views who we are and what we are able to do by how our bodies appear. -- adapted from jacket and preface.

Stand up straight
Our bodies are not fixed, they change over time. They vary with alterations in diet, exercise and illness, and shift as we age. Our attitudes to bodies, and especially to posture – how people hold themselves, how they move – are also fluid. Our stance and gait are interpreted as healthy or ill, able or disabled, elegant or slovenly, beautiful or ugly. In Stand Up Straight!: A History of Posture Sander L. Gilman probes these shifting concepts of posture to show how society views who we are and what we are able to do by how our bodies appear. From Neanderthal man to modern humans, Gilman shows how we have used our understanding of posture to define who we are – and who we are not. The book traverses theology and anthropology, medicine and politics, and ranges from discarded ideas of race to the most modern ideas of disability, and from theories of dance to concepts of national identity. Interweaving the history of posture with our developing knowledge of anatomy and cultural history, and fully illustrated with an array of striking images, Stand Up Straight! is the first comprehensive history of the upright body at rest and in movement.

Lifestyle factors and determination of optimal cut-off values for forward head posture in young adults with neck pain: a cross-sectional analysis
Background
Neck pain is a common condition across various populations, with a substantial impact on daily life and quality of life. Forward head posture is frequently observed in individuals with neck pain and is closely associated with lifestyle factors. This study aimed to examine the relationship between lifestyle factors and forward head posture in young adults with neck pain and determine the optimal cutoff value for assessing the risk of forward head posture.
Methods
In total, 200 men and women aged 35–44 years with persistent or recurrent neck pain with a numeric rating scale score of ≥ 3 in the previous week were included in the study. The participants’ sex, age, medical history, anthropometric parameters, posture- and activity-related lifestyle, pain, radiographs, and the craniovertebral angle were obtained. The associations between lifestyle factors and forward head posture were analyzed using logistic regression. The cutoff values for risk prediction were analyzed using receiver operating characteristic curves. The impact of lifestyle factors on changes in craniovertebral angle at the 6-month follow-up was analyzed using multiple linear regression and analysis of covariance.
Results
After adjusting for covariates, there were significant differences in lying time (odds ratio = 3.342, 95% confidence interval = 1.607–6.952) and physical activity level index (odds ratio = 0.404, 95% confidence interval = 0.210–0.775) between the forward and non-forward head posture groups. The cutoff values for detecting forward head posture were 6.50 h of lying time and a physical activity level score of 2.88. At the 6-month follow-up, the craniovertebral angle was closer to the diagnosis of forward head posture, with increasing lying time and lower physical activity level score; however, the association was not statistically significant.
Conclusions
The findings indicate that lying time and physical activity level scores are important lifestyle-related predictors of forward head posture. Thus, lying time and physical activity level should be addressed to predict and prevent forward head posture.

Kings into gods : how prostration shaped Eurasian civilizations
\"One might be surprised, astonished or indignant seeing men and women prostrating themselves in front of other men and other women. Or one might feel it is right to bow down before God, Allah, the saints, the Holy Virgin or the gods. Kings into Gods: How Prostration Shaped Eurasian Civilizations investigates the reasons why men prostrate themselves before deities or before powerful men. Through an in-depth historical and cultural analysis, this book highlights the connection between rituality and royalty within the Eurasian civilizations. The narrative and iconic documentation gathered and analyzed concerns the Greek and Roman world, the Mongolian civilization during the Middle Ages, the Hindu and Chinese civilizations, the Islamic civilization in India in the fourteenth century, the Mughal civilization and European civilization in the late Middle Ages. The different forms of the rituals in the courts of kings and emperors are tightly connected with the concept of royalty. The prostration is an act of humiliation of defeated enemies, a means to establish an abysmal distance between powerful elite and the people, a way of creating hierarchies within the elite itself\"-- Provided by publisher.

Viewing low back pain through the lens of spinal evolution: Understanding the morphology and limits of the human spine
Low back pain remains a pervasive global health challenge, with significant disability and socio-economic burden. While contemporary biomechanical and occupational factors are well-studied, the role of human spinal evolution and its divergence from modern postural behaviors is less frequently examined. This study aims to visually explore and illustrate the historical evolution of human spinal posture through artistic representations, conceptually highlighting the potential biomechanical mismatch between our spine's evolutionary adaptations and current lifestyle-driven postures.
We conducted a qualitative visual analysis of human figures depicted in selected artworks from three distinct historical periods: the hunter-gatherer era, the agricultural transition, and the post-industrial age. Observed spinal postures were qualitatively compared to established biomechanical data on intradiscal pressure levels, derived from previous in-vivo studies. This comparison was used to illustrate potential physiological or pathological loading on the spine across different historical contexts.
Our visual observations suggest a noticeable shift in depicted human postures over time. Figures from the hunter-gatherer period primarily exhibit upright, dynamic positions with an apparent absence of prolonged sitting or significant forward flexion. In contrast, artworks from agricultural and post-industrial societies frequently portray individuals in more flexed, static, and often ergonomically suboptimal postures, including prolonged sitting, bending, and heavy lifting with improper form. These observed postural trends visually align with positions independently associated with increased intradiscal pressures and greater spinal strain in biomechanical literature.
This study visually traces the evolution of human spinal posture from the hunter-gatherer era to modern industrial life, highlighting a shift from dynamic, biomechanically healthy positions to static and suboptimal postures. These changes, reflected in historical art and linked to lifestyle transitions such as agriculture and industrialization, may underlie the rising prevalence of spinal disorders. The findings suggest that aligning modern practices with the spine's evolutionary design could help prevent and manage spinal pathologies.

Conceptualizing 20 years of engaged scholarship: A scoping review
Engaged scholarship, a movement that has been growing steadily since 1995, offers a new way of bridging gaps between the university and civil society. Numerous papers and reports have been published since Boyer's foundational discourse in 1996. Yet, beyond a growing interest in orienting universities' missions, we observed a lack a formal definition and conceptualization of this movement. Based on a scoping review of the literature over the past 20 years, the objective of this article is to propose a conceptualization of engaged scholarship. More specifically, we define its values, principles, and processes. We conclude with a discussion of the implications of this new posture for faculty and students, as well as for the university as an institution.

Chronic impairments of static postural stability associated with history of concussion
Postural stability deficits are commonly observed in cases of concussion. However, the objective duration in which impairments of standing postural stability remain following a concussion is often inconclusive. The present study was conducted to determine if prior history of concussion is associated with deficits in postural stability beyond the clinical determination of recovery. It was hypothesized that concussion history would be associated with decreases in static stability compared to individuals that have never sustained a concussion. Fifty-four healthy adults were recruited based on whether they reported sustaining one or more prior concussions (n = 27) or no history of concussion (n = 27). Participants were instructed to stand on a force platform to track center-of-pressure (CoP) during standing for thirty seconds under four conditions based on stance and number of tasks: (1) bipedal, single-task, (2) bipedal, dual-task, (3) unipedal, single-task, and (4) unipedal, dual-task. Results revealed that individuals with a history of concussion demonstrate significantly reduced postural stability under dual-task conditions as evidenced by increases in average displacements and elliptical area of postural sway as well as reductions in CoP sample entropy. However, there were no significant differences in CoP displacement or elliptical area between groups under single task conditions. Overall, these findings indicate that concussion is associated with impairments of maintaining standing postural stability that remain evident approximately 7 years following clinical resolution of the initial injury. The exacerbation of these impairments under dual-task conditions indicate that concussion can result in a reduced capacity to allocate proper attention resources to multiple concurrent objectives.

Twenty-four hour intraocular pressure monitoring with the SENSIMED Triggerfish contact lens: effect of body posture during sleep
PurposeTo determine the difference in relative intraocular pressure (IOP) measured by the SENSIMED Triggerfish (TF) contact lens in flat compared with 30° head-up sleeping positions in patients with progressive primary open-angle glaucoma or normotensive glaucoma, based on recent or recurrent disc haemorrhage.DesignProspective, randomised, cross-over, open-label comparative study.MethodsIOP was monitored for 24 hours using TF on two separate sessions. Patients were randomly assigned to sleep flat one night and 30° head-up the other. Outputs in arbitrary units were obtained. Sleep and wake periods were defined as 22:00–6:00 and 8:00–22:00, respectively. Mean TF values during sleep and wake periods and wake–sleep and sleep–wake slopes were calculated for each session. TF output signals were compared between positions.ResultsTwelve subjects completed the study. Significant mean positive slopes were noted during the sleep period for both positions (p<0.01). No significant differences in the TF mean values were observed between positions (p=0.51). Six (54%) subjects had mean TF values significantly higher during the flat supine session, while four (36%) subjects had higher values during the head-up session. A significant increase in Goldmann IOP (p=0.001) and TF (p=0.02) measurements were observed after 24 hours of TF wear (‘drift phenomenon’).ConclusionsSleep position affects IOP as measured by TF in some patients with progressive glaucoma. The upward drift in TF output detected in >50% of the subjects requires further investigation to establish whether the increased output values over time are an artefact induced by the TF or a real change in IOP.Trial registration numberNCT01351779

The Posture of ILalitāsana/I: Buddhist Posing Hierarchy in a Tang-Dynasty Chinese Bronze Sculpture
The rubric of the presence of Buddhist sculpture in the absence of an actual deity represents an admirable aspect of Buddhist art, especially sculpture, where the best works have drawn on this paradox in an astounding fashion. An important element in the realization of this religious archetype is the Buddhist statues' sublime poses. This article demonstrates the Buddhist posture hierarchy, based on a case study of a Tang-Dynasty Chinese Buddhist Bronze collected by the Pulitzer Arts Foundation, the posture of which is identified as lalitāsana: one leg pendant and the other bent horizontally. This article shows how this pose engendered various other compositional situations and postures popular in East Asia icon design and, moreover, that this sculpture might form part of an assemblage, where the pose indicates the central Buddha figure, to which all of the other figures are formally and doctrinally posed following a hierarchy. This article argues that Buddhist figures of different religious ranks are characterized by their pose and degree of movement. This research proves that the myriad forms of Buddhist postures and hierarchy have been devised to illustrate mythologies and philosophical, doctrinal, or social concepts, and their representations, in turn, have engendered other myths and beliefs.
