OBJECTIVE To evaluate methods of prevention of scrotal hyperthermia in laptop computer (LC) users. DESIGN Experimental study. SETTING University hospital. PATIENT(S) Twenty-nine healthy male volunteers. INTERVENTION(S) Right and left scrotal temperature and LC and lap pad temperatures were recorded during three separate 60-minute sessions using a working LC in a laptop position: session...

Materials and methods The study comprised 996 girls, aged 9 to 13, mean 11.0 ± 1.0 years of age. ATI measurements were performed at three levels of the spine: proximal thoracic, main thoracic and thoracolumbar/lumbar. Maximal ATI values for standing and sitting forward bending positions were noted. Based on the ‘7°’ criterion, the number of children who need follow up was revealed, according to...

BACKGROUND The impact of blood sampling in sitting vs supine positions on measurements of plasma metanephrines for diagnosis of pheochromocytoma is unknown. METHODS We compared plasma concentrations of free metanephrines in samples from patients with primary hypertension obtained after supine rest with those obtained in the sitting position without preceding rest. We also assessed the effects...

The use of the sitting position in neurosurgery is often associated with decreased arterial pressure (MAP) and stroke volume index (SVI). A shift in blood from the intra- to the extrathoracic compartment may be responsible for this cardiovascular response. However, little is known of the amount of shift in blood volume after transfer from the supine to the sitting position. Therefore, we measur...

Introduction It is sometimes difficult for some patients to optimally flex their hips and knees making traditional position for induction of spinal anaesthesia difficult to achieve. The ease of induction of spinal anaesthesia was compared with patients in sitting position with legs remaining on the table (new sitting method) versus legs placed on the side stool (traditional sitting method). M...

[Purpose] The purpose of this study was to compare the changes in trunk and shoulder angles, and reaction forces under the two hands elicited by different hand base of support positions during sitting pivot transfer. [Subjects and Methods] Eighteen unimpaired subjects performed independent sitting pivot transfer. Subjects performed sitting pivot transfer between an initial seat to a target seat...

OBJECTIVES To determine (1) whether the shear modulus in upper trapezius muscle myofascial trigger points (MTrPs) reduces acutely after dry needling (DN), and (2) whether a change in posture from sitting to prone affects the shear modulus. DESIGN Ultrasound images were acquired in B mode with a linear transducer oriented in the transverse plane, followed by performance of shear-wave elastogra...

[Purpose] The purpose of this study was to investigate the effect of co-stabilizer muscle activation on knee joint position sense. [Subjects and Methods] This study was a pre-post, single-blinded randomly controlled trial (angle sequence randomly selected) design. Seven healthy adults with no orthopaedic or neurological problems participated in this study. Knee joint position sense was measured...

BACKGROUND AND OBJECTIVES The change from the sitting position to supine position, general anesthesia, and surgical procedure reduce lung volumes and this effect can be greater in obese patients. The objective of the present study was to evaluate the influence of the sitting position, 30 dorsal inclination, and horizontal dorsal decubitus on spirometry of grade III obese patients. METHODS Twe...
