Guest Lecture A Young female with autonomic failure is described. She successfully reduced the symptoms of orthostatic hypotension by application of physical manoeuvres like leg-crossing, bending forward and placing a foot on a chair. The beneficial effects of these manoeuvres can be explained by a small (10–15 mmHg) increase in mean arterial pressure to a level just sufficient to maintain adequate cerebral blood flow. The underlying common mechanism appears to be an increase of thoracic blood volume by translocation of blood from the vascular beds below the diaphragm to the chest. Instruction in these physical manoeuvres should be part of the management programme to reduce the disabilities arising from postural hypotension in patients with autonomic failure.
