[Effect of various modes of electric stimulation of lower extremity skeletal muscles on indicators of peripheral blood flow].
Various modes of electrostimulation of the musculus gastrocnemius (MG) were examined for effect on doppler parameters of blood flow in the popliteal artery and vein of 15 healthy subjects at the age 30.6 +/- 1.5 years. The strongest effect on the circulation in the popliteal artery was observed at the stimulation with 16-second stimulus alternating with 16-second pause. Such mode led to dilation of the artery diameter by 16.2%, maximal blood flow speed increased by 50.6%, time-averaged circulation was by 60.4% faster. Electrostimulation of the crural muscles also induced dilation of the popliteal vein and accelerated relevant circulation. These changes were also most evident in the stimulation mode 16-second stimulation intermittent with a pause.
