STUDY DESIGN Radiographic review of healthy volunteers. PURPOSE To determine the ideal sitting positions by measuring changes in lumbar lordosis (LL) and pelvic parameters (PPs) in various positions. OVERVIEW OF LITERATURE Prolonged sitting is generally accepted as an important risk factor for low back pain (LBP). It is now recognized that spinopelvic alignment is important for maintaining ...

AIMS The aim of this study was to examine whether there is any difference between BP readings with patients crossing a leg at the knee level and uncrossing during BP measurement. BACKGROUND It is clear that numerous factors influence an individual's blood pressure (BP) measurement. However, guidelines for accurately measuring BP inconsistently specify that the patient should keep feet flat on...

The potential for serious complications after venous air embolism and successful malpractice liability claims are the principle reasons for the dramatic decline in the use of the sitting position in neurosurgical practice. Although there have been several studies substantiating the relative safety compared with the prone or park bench positions, its use will continue to decline as neurosurgeons...

PURPOSE To evaluate the safety and efficacy of surgeon's superior sitting position during temporal clear corneal incision (TCCI) phacoemulsification, with a 90° working angle, during combined phacovitrectomy. METHODS Prospective interventional case series were performed on 65 eyes of 63 patients. TCCI phacoemulsification was done in all cases (whether right or left eyes), while the surgeon wa...

To optimize the shape of the interface between the skin and a sitting support a Finite Elements model is needed. The geometry of the model was based on (i) in vivo measured skin shape data of the upper leg and the buttock area, and the position of a set of bony landmarks, /nr in vitro measured bone shape data of the Visible Human Dataset, (ii) auxillary surfaces to bridge the skin and the bone ...

27 The aim of this study was to determine how muscle activity and body orientation contribute to 28 the triceps surae spinal transmission modulation, when moving from a sitting to a standing 29 position. Maximal H-reflex (Hmax) and motor potential (Mmax) were evoked in the soleus 30 (SOL), medial and lateral gastrocnemius in 10 male subjects and in three conditions: passive 31 sitting, upright ...
