The author recalls the role of the autonomic nervous system and the means of investigation
of this system in orthostatic hypotension occurring in tetraplegic individuals and the …

Orthostatic examinations were performed with a tilt table on 64 male volunteers, of whom 21
had sustained amputation of one or both lower limbs and 23 were paraplegic due to spinal …

Patients who are tetraplegic with cervical spinal cord transection do not appear to have
cerebral control over the sympathetic nervous system. Soon after transection they are often …

1. A study has been made of the effect of head‐up tilt on blood pressure, heart rate, forearm
blood flow and occluded vein pressure in the hand and foot in non‐bedridden patients with …

The effects of bladder stimulation, skeletal muscle spasms and head-up tilting were
observed in seven patients with complete cervical cord lesions. Measurements were made …

Cardiovascular control was studied in five tetraplegic patients with physiologically complete
cervical spinal cord transections. All had been injured less than two weeks previously and …

DESPITE uncertainty about the anatomical and functional basis of the circulatory
disturbance in idiopathic orthostatic hypotension, various methods of symptomatic treatment …

The cardiovascular adaptation of tetraplegic to the upright position has been previously
demonstrated to be deficient. Presumably this is due to the interruption of the spinal …

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 …

The mechanism responsible for the gradual improvement in blood pressure control in
tetraplegic subjects is not known. This study was undertaken to determine the presence of …
