results the rate of first-time successful spinal needle insertion was not significantly different between the clsp and tsp groups (62.9% versus 55.7%, p > 0.05). ease of landmark palpation in the clsp group was not significantly different from that in the tsp group (86.7% versus 76.4%, p > 0.05). the number of needle-bone contacts in both groups were not significantly different (p > 0.05). the ...

OBJECTIVES To evaluate the effect of posture change from the supine to the sitting position and before and after passive leg raising on maternal functional hemodynamics in pregnant women at 35-37 weeks' gestation, and to compare the changes in pregnancies that subsequently developed pre-eclampsia (PE) or gestational hypertension (GH) with those that remained normotensive. METHODS In 2764 sing...

purpose: to evaluate ophthalmologists’ sitting position during ocular examination and surgery and to evaluate any correlation between musculoskeletal disorders and mean work time.   methods: this cross-sectional study was performed on ophthalmologists in isfahan, iran in different occupational positions including the office, during slitlamp examination and in the operating room. the evaluation ...

Atherosclerotic peripheral artery disease primarily manifests in the medium- to large-sized conduit arteries of the lower extremities. However, the factors underlying this increased vulnerability of leg macrovasculature to disease are largely unidentified. On the basis of recent studies, we propose that excessive time spent in the sitting position and the ensuing reduction in leg blood flow-ind...

Introduction World wide approximately 1.5 billion passengers travel by aircrafts yearly. In the past years there have been increasing reports suggesting a causal link between longhaul flights and thromboembolic events. It has been postulated that besides sitting in a cramped position DVT may be triggered by aircraft-specific factors. Whether these aircraft-specific factors (moderate hypoxia, lo...

The aim of this study was to examine the effects of the sitting posture on the lower limb venous flow and to explore the beneficial effects of neuromuscular electrical stimulation (NMES) and an ottoman-type seat on the venous flow. Healthy adult volunteers without a history of lower limb surgery or thromboembolism were recruited, and the flow velocity, cross-sectional area, and flow volume of t...

BACKGROUND The patient's position during spinal anesthesia administration plays a major role in the success of spinal needle insertion into the subarachnoid space. The traditional sitting position (TSP) is the standard position for spinal anesthesia administration, but the success rate for spinal anesthesia administration in the TSP is still quite low. The crossed-leg sitting position (CLSP) is...

The scoliometer readings in both standing and sitting position of 2071 children and adolescents (1099 boys and 972 girls) aged from 5 to 18 years old were studied. The angle of trunk rotation (ATR) was measured, in order to quantify the existing trunk asymmetry. Children and adolescents were divided in two groups according to the severity of trunk asymmetry. In the first group asymmetry was 1 t...

The study investigates the effects of eccentric exercise of the quadriceps on proprioception of the knee in weight and non-weight bearing tasks. Proprioception of the exercised leg was assessed at 120° and 150° of knee extension in 15 healthy adults (age 25.0 ± 3.6 yrs) before, immediately after, and 24h following eccentric exercise of the quadriceps. Three tests of proprioception were performe...
