OBJECTIVE To assess whether the risk of severe blood loss is increased in semi-sitting and sitting position, and if so, to which extent blood loss from perineal damage is responsible for this finding. DESIGN Secondary analysis of data from a large trial. SETTING Primary care midwifery practices in the Netherlands. POPULATION About 1646 low-risk women who had a spontaneous vaginal delivery...

This study aimed to assess the differential impacts of lumbosacral orthosis (LO) wear in different sitting conditions through posturographic measurements. Twelve healthy subjects sat on a force platform with three variable stability levels (stable and on seesaws with a long and short radius, inferring slightly and highly unstable sitting, respectively) and three orthosis conditions (no LO, neut...

Cerebral disorders are often associated with disturbance of consciousness. Since the latter could alter the prognosis of physical function, early improvement of consciousness level is important. The present study tested the hypothesis that sitting position improves disturbances of consciousness in patients with cerebral disorders. The subjects were 17 patients with cerebral disorders and distur...

OBJECTIVE To compare the effect of induction position on block characteristics (sensory and motor nerves) and haemodynamic stability in elderly patients with isobaric bupivacaine. Patient comfort was also looked at. METHODS The randomized single blinded study was conducted at the Aga Khan University Hospital, Karachi, from September 2007 to August 2008.

AIM The aim of this study was to determine the reproducibility and reliability of optic disk evaluation in supine subjects with a Heidelberg Retina Tomograph II (HRT II). METHODS One eye was randomly selected for evaluation by HRT II in each of eleven healthy subjects. Five images were obtained by each of two experienced operators at two separate visits with the subjects in both sitting and s...

BACKGROUND previous evidences suggested that traditional sitting position (flexion of knees approximately 90°, and adduction of hips while feet rest on a stool) and hamstring stretch position (sitting position with maximum extension of knees, adduction of hips, and forward bending) both reversed the lumbar lordosis and the number of spinal needle-bone contacts were identical when placing patien...

[Purpose] This study determined the change in lumbar position sense according to lumbar angles in a flexion pattern (FP) subgroup of patients with non-specific chronic low back pain (NCSLBP). [Subjects] Thirteen subjects with FP low back pain participated. [Methods] The lumbar repositioning error (RE) of subjects was measured between a neutral starting position and re-position phases at three a...
