endo- and exogenous ones, realize their pathological action in different ways and
influence first of all the contractile apparatus of somatic muscle fibers [157].
The developed methods and the determined informative parameters became a
basis for the development of some variants of software for the laser specklometer.
5.8 Development of Diagnostic Speckle-Optical Criteria
for Estimation of Skin Microhemodynamics
Contemporary methods of coherent optics give the possibility to visualize the surface
blood flow without contact. Estimation of the skin blood flow is important while
ascertaining the diagnostics as well as during individual therapy of a number of
diseases, for example, polyneuropathy, angiopathy, arterial thrombosis and other
disorders.
In clinical practice, the role of non-contact methods cannot be overestimated
as they do not require sterilization. Such works are conducted in Germany, Japan,
the USA and a number of other industrialized countries and directed first of all to
ascertaining qualitative characteristics of the blood flow [44, 75, 84, 158–160], which
are necessary for the development of diagnostic criteria.
An overwhelming number of researchers conduct experiments on determination
and measuring of microcirculation in one single point. The only exception is the
work [75] where two-dimensional pictures of the blood flow are made with electromechanical scanners in combination with registration with a one-dimensional
DAS rule.
Development of the technology of photoreceivers and telemetry intensified with
the power of contemporary PCs gives the possibility to begin development of sensitive noninvasive systems of determination of the surface blood flow. The systems
can visualize great areas and make tests in all the necessary points. Observation
of distribution of microcirculation and following the dynamics of this distribution
under a number of physiotherapeutic means on the one hand will definitely favor
the development of new methods of diagnostics, and on the other hand it is aimed
at optimization and acceleration of the process of treatment. In a number of cases,
observation of the skin blood flow is also complicated as it is sensitive to changes in
temperature and depends on the state of skin and pressure on the skin. That is why
the determination of the actual blood flow without any influence of the measurement itself can be possible while using the non-contact noninvasive speckle-optical
method.
The use of the speckle-optical method for studying microhemodynamics in skin
excludes sterilization, allows probing any place on the skin with obtaining objective
results and enables to make measurements in patients with tactile hypersensitivity
and skin vulnerability who suffer from peripheral circulatory disorders, different
dermatoses and skin allergic onsets, and eliminates the risk of contracting both
transcutaneously transmitted diseases and the human immunodeficiency virus (HIV).
