conclusions in squatting position the number of spinal needle-bone contacts was lower compared to the traditional sitting position, nonetheless ease of needle insertion or space identification was the same in the both groups. results the total number of spinal needle bone contact was statistically lower in the squatting position compared to traditional sitting position group (222 versus 230 res...

OBJECTIVE To assess the risks and benefits of squatting position during second stage of labour and its comparison with the supine position. METHODS The study was conducted at the Department of Obstetrics and Gynaecology, Jinnah Postgraduate Medical Centre, Karachi from 1st January 1999 to 31st January 2000. A total of two hundred patients of similar ante partum, intrapartum and socio-economic...

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...

OBJECTIVE This work aimed to analyze the association between maternal position at birth in spontaneous deliveries and the occurrence of anal sphincter tears (AST) given the lack of evidence related to the least traumatic birth position. STUDY DESIGN A total of 7832 vaginal deliveries were included. Vaginal-operative deliveries and deliveries with fundal pressure were excluded. Birth positions...

The structural changes that a function may bring about like morphological differences observed between bones of different populations are of much interest. Squatting is a good example of such behaviour/function producing skeletal markers on the bones. The squatting position puts strong pressure and traction forces on the knee and ankle joints, producing specific bone markers that reflect the re...

Clinicians frequently assess movement performance during a bilateral squat to observe the biomechanical effects of foot orthotic prescription. However, the effects of rearfoot position on bilateral squat kinematics have not been established objectively to date. This study aims to investigate these effects in a population of healthy adults with a pronated foot type. Ten healthy participants with...

The squatting test is an active posture manoeuvre that imposes one of the most potent orthostatic stresses. In normal subjects, the changes in blood pressure and heart rate are transient because of appropriate baroreflex homeostasis and do not provoke symptoms. However, in various pathological conditions, both the increase in blood pressure during squatting and the decrease in blood pressure du...

In certain disease states prolongation of the QT interval has been shown to be arrhythmogenic. Whether QTc interval changes with position and thus whether certain positions are more arrhythmogenic than others is not known for different diseases that predispose to arrhythmias, and was therefore studied. Patients with left ventricular hypertrophy and heart failure, and the appropriate matched con...
