Abstract
Plasma levels of β-endorphin, vasopressin and Cortisol during head-up tilt were measured in tetraplegic patients and in normal healthy subjects. In tetraplegic patients rapid tilt from the horizontal to 30° or 60° head-up induced orthostatic hypotension and increased plasma levels of Cortisol, β-endorphin and vasopressin. In control subjects head-up tilt failed to alter plasma levels of these hormones. These data show that the head-up position in tetraplegics causes various endocrine reactions.
