ABSTRACT
The aim was to study the dynamics of ankle-brachial index (ABI) after treadmill test, after six-minute walk test (SWT) and after electric muscle stimulation (EMS) in aged patients. We conducted a survey of 80 aged patients (73,0 +/- 16,0 years). ABI was determined at rest and immediately after the following tests: 1) treadmill-test for five minutes, 2) SWT, and 3) EMS for five minutes. Atherosclerotic lesions of lower limb arteries was absent only in 21,3% of patients according to color duplex scanning. ABI significantly decreased on both limbs after treadmill-test ant after SWT. During EMS, in contrast, ABI was increased. Thus, you can use SWT in the diagnosis of subclinical atherosclerosis in a general clinical practice as an alternative to treadmill-tests. Good tolerability of EMS patients and ABI increase show the availability of EMS in physical rehabilitation of aged patients with peripheral atherosclerosis.

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.

Of 103 patients with acute coronary syndrome (mean age 51.6 +/- 0.9 years) 47 patients participated in 5 group psychotherapeutic sessions added to conversional rehabilitation program. Psychotherapy included progressive muscular relaxation, neurolinguistic programming, eriksonian hypnosis, therapeutic metaphora. Psychotherapy decreased the hear rate, number of ventricular extrasystoles, stimulated tonicity of the parasympathetic nervous system. Compared to the controls, the test patients developed higher exercise tolerance and lower reactivity of the central hemodynamics in all the exercise tests.
