1. Cardiovascular responses to external stimuli (ice or pinprick) in 10 paraplegic patients were studied. Blood flows above and below the level of the lesion, blood pressure, pulse and cardiac output were measured. As controls, four normal subjects and six patients who had undergone sympathectomy for peripheral vascular disease were used. 2. Cutaneous stimuli produce, in a paraplegic patient with complete transection of the spinal cord above the level of the sympathetic outflow, a more marked and more widespread vasomotor response in the denervated area than a similar stimulus produces in a normal subject. 3. A paraplegic patient with complete transection of the spinal cord above the level of the sympathetic outflow can register reflex vasoconstriction in the contralateral limb after strong external stimulus without experiencing pain and with the reflex arc being complete below the level of the lesion.

    Skin blood flow (SKBF) was evaluated during arm-cranking exercise in able-bodied control subjects (AB; n=6) and in individuals with low- (LP; T10–T12 lesions; n=6) and high-level paraplegia (HP; T5–T9 lesions; n=6), using laser Doppler flowmetry (LDF). During moderate exercise SKBF...

    The veno-arteriolar reflex (VAR) in spinal-cord-injured subjects (SCI) has been attributed little interest, although it might contribute substantially to their blood redistribution. This peripheral reflex response, which is based on an axon reflex, consists of a reduction in limb blood flow...

    Vasomotor effects of skin exposure to carbon dioxide (CO2) have been described in normal subjects. It was of interest, therefore, to determine whether percutaneous 2 is of therapeutic benefit. In a randomized, double-blind study, 10 patients with lower limb arteriopathy (stage II) were...

    Objective: In patients with acute myocardial infarction (AMI), coronary vasomotor function is impaired in the myocardial territory supplied by the culprit artery and in remote myocardium supplied by angiographically normal vessels. The aim was to investigate the temporal evolution...

    Purpose: Much is known about the control of blood flow, yet gaps remain concerning the interactions of deep-body and peripheral thermal feedback. In this experiment, changes in the vascular tone of the hands and feet were mapped to demonstrate the separate and combined influences of mean body...
