BACKGROUND Downward shifts in blood volume with changing position generally cause tachycardic responses. Age-related decreases in vagal nerve activity could contribute to orthostatic hypotension in older individuals. Fowler's position is a reclined position with the back between 30° and 60°, used to facilitate breathing, eating, and other routine daily activities in frail and elderly patients. ...

Multiple anomalies in the celiac arterial system presents as rare vascular malformations, depicting deviations of the normal vascular developmental pattern. We found a common left gastro-phrenic trunk and a hepato-spleno-mesenteric trunk arising separately from the abdominal aorta in one cadaver. We also found a common hepatic artery and a gastro-splenic trunk arising individually from the abdo...

The celiac trunk and the mesenteric arteries may present variations with different clinical significance. A celiacomesenteric trunk was discovered in a patient with mesenteric ischemia and a history of aortic bypass without inferior mesenteric artery reimplantation. Despite thrombectomies and digestive resections, the patient died. Anatomic variations like celiacomesenteric trunk must be known ...

OBJECTIVE To assess the interaction of foot placement, trunk frontal position, weight-bearing and knee moment asymmetry at seat-off when rising from a chair. DESIGN Cross-sectional study. SUBJECTS Seventeen subjects with hemiparesis and 15 healthy controls. METHODS Trunk position, weight-bearing and knee moment asymmetry were quantified by kinetic and kinematic analysis when the subjects ...

The development of reaching is crucially dependent on the progressive control of the trunk, yet their interrelation has not been addressed in detail. Previous studies on seated reaching evaluated infants during fully supported or unsupported conditions; however, trunk control is progressively developed, starting from the cervical/thoracic followed by the lumbar/pelvic regions for the acquisitio...

This study investigated the trunk kinematics and electromyographic (EMG) activity of eight trunk muscles when "expected" and "unexpected" loads were applied directly to the torso. Twenty individuals (mean age: 25.1 yr; range 20-33 yr) participated in this mixed model study in which gender was the between-subjects factor, and expectancy and symmetry of the applied load were within-subject factor...

To obtain breast motion relative to the trunk, skin markers are used to define a local coordinate system (trunk), with respect to the global reference frame. This study aimed to quantify any differences in multiplanar breast displacement relative to the trunk using the first axis of rotation as either the mediolateral or longitudinal axis. Ten female participants ran on a treadmill (10 kph) in ...

There is increasing evidence that individuals with non-specific low back pain (LBP) have altered movement coordination. However, the relationship of this neuromotor impairment to recurrent pain episodes is unknown. To assess coordination while minimizing the confounding influences of pain we characterized automatic postural responses to multi-directional support surface translations in individu...

[Purpose] Seated side tapping test (SST) performance is associated with mobility impairment in the elderly. Although this test was developed to assess trunk function, interpretation of its results may be confounded by the upper-limb movements in its protocol. Here, this study aimed to validate the association between trunk function and gait function by means of the Arms Crossed SST (AC-SST), a ...

The objective of this study was to evaluate the long-term effects of the task-specific training with trunk restraint compared with the free one in poststroke reaching movements. The design was randomized trial. The setting was University of Campinas (Unicamp). Twenty hemiparetic chronic stroke patients were selected and randomized into 2 training groups: trunk restraint group (TRG) (reaching tr...
