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 ...

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 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...

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 ...

Respiratory function was studied in 19 patients placed in both the supine and sitting positions in the early postoperative period. Although the sitting position was expected to improve respiratory function, no such advantage was found; instead, a small but statistically significant deterioration in arterial oxygenation was found in most patients when sitting up. It is concluded that no respirat...
