[Purpose] The purpose of this study was to study the changes in pulmonary functions in relation to lying positions of experimental participants. [Subjects and Methods] Twenty participants participated in this experiment. Measurements were taken in the supine position, the left side-lying position, the right side-lying position, and the prone position. Vital capacity (VC) was evaluated using a Fit mate. [Results] A comparison of four lying position showed significant differences in participants' VC. In comparison of four position, supine and left sidelying, and between supine and right sidelying, and between supine and prone, between left sidelying and prone. [Conclusion] In conclusion, changing the participants lying position produce changes in pulmonary functions. The greatest change occurred with a supine lying position. We presume that ventilation is affected by body structures. The results provide objective data for establishing the most suitable positions for stroke patients performing respiratory exercises.

The interplay between lying, sitting, standing, moving, and walking on obesity risk in older adults: a compositional and isotemporal substitution analysis.
BMC Geriatr

Introduction: Obesity in older adults is linked to various chronic conditions and decreased quality of life. Traditional physical activity guidelines often overlook the specific postures and movements that older adults engage in daily. This study aims to explore the compositional associations between posture-specific behaviours and obesity risk in younger (M = 67.

Purpose: Achieving precise postoperative alignment is critical for the long-term success of total knee arthroplasty (TKA). Long-leg standing radiograph (LLR) at 6 weeks post-op is the gold standard for assessing alignment, but its reliance on weight-bearing and positioning makes it less practical in the early postoperative period. Supine computed tomography scanogram (CTS) offers a potential alternative.

Vaginal pessaries have been used for millennia to alleviate symptoms of pelvic organ prolapse (POP). Despite their long-standing use, the success rate of pessary treatment is approximately 60%, and the underlying mechanisms of support are not well understood. This study aims to investigate three previously proposed hypotheses regarding the support mechanisms of pessaries, utilizing supine and upright magnetic resonance imaging (MRI): (1) support by bony structures, (2) support by levator ani muscles (LAM), and (3) the uterus keeping the pessary in place by acting as a lever.

Introduction: Maternal position plays an essential role in achieving labour progress as it supports the physiological mechanisms of labour. Evidence supports that adopting upright positions may facilitate physiological childbirth.
Aim: To describe the use of various positionsamong nulliparous pregnant women in the last 24 h before birth and describe physical positions in relation to maternal and neonatal outcomes at time of birth.

Videofluoroscopy, recognized as the gold standard for dysphagia exploration, has inherent limitations, including poor soft tissue discrimination, radiation exposure, and aspiration risk. In response to these challenges, cine-MRI of swallowing has evolved over the past three decades, yielding diverse methodologies and results across various studies.This systematic review, conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, meticulously outlines cine-MRI protocols, applications, advantages, and limitations.
