First Time

The aim of the study is to describe the temperature and hemodynamic effects that occur during the pressure cuff test (CT). Materials and methods. The reaction to CT has been studied by thermography, photoplethysmography, magnetic resonance imaging and ultrasound dopplerography. Results. At rest oscillations in skin temperature and hemodynamics of the left and right hands were synchronous. During occlusion a vasoconstriction of arteries below the cuff occurred, the blood being deposited in the venous bed. The opening of the sweat channels on the fingers of the subjects during the application and/or removal of occlusion was recorded for the first time. Conclusions. Occlusion leads to a transition from the oscillatory regime of changes in the tonus of the vessels of the shoulder and hand to the regime of vasoconstriction, and after the removal of occlusion - to vasodilation.

Biphasic Responses

ABSTRACT:Cutaneous reflexes in the upper limb were elicited by stimulating digital nerves and recorded by averaging rectified EMG from proximal and distal upper limb muscles during voluntary contraction. Distal muscles often showed a triphasic response: an inhibition with onset about 50 ms (Il) followed by a facilitation with onset about 60 ms (E2) followed by another inhibition with onset about 80 ms (12). Proximal muscles generally showed biphasic responses beginning with facilitation or inhibition with onset at about 40 ms. Normal ranges for the amplitude of these components were established from recordings on 22 arms of 11 healthy subjects. An attempt was made to determine the alterent fibers responsible for the various components by varying the stimulus intensity, by causing ischemic block of larger fibers and by estimating the afferent conduction velocities. The central pathways mediating these reflexes were examined by estimating central delays and by studying patients with focal lesions
