neuromuscular systems and also other diseases connected with the disorders of
metabolic processes, into the clinical practice, are presented in the given
monograph.
One of the first goals of Leonid V. Tanin at that time was to develop physical
principles of a new generation of precision medical–biological devices based on the
holography and speckle-optics for the remote noninvasive diagnostics of diseases
and highly precise preventive examinations with sensitivity and big spatial resolution that allowed to increasing the objectivity, information value and reliability of the
derived results. On the basis of these developments, laser speckle-optical microhematomyograph (laser specklometer), holographic microscope, laser-holographic
complex (holographic cardiograph) for contactless defining surface blood flow with
marking out the components of this integration process, were created.
In the result of the studies conducted under the guidance and direct participation
of Leonid V. Tanin during several years in the Research Institute of Neurology,
Neurosurgery and Physiotherapy of the BSSR together with the Institute of Physics
of the Academy of Sciences of the BSSR, it was first found out that the change of
muscle tonus accompanied by the changes of oscillations of muscles fiber and
adjacent tissues deforms spectrum of fluctuations of speckle-field. Measurements of
spectrum characteristics of dynamic laser speckle-field, formed at the reflection of
light from the tissue over the contraction muscle, allowed significantly supplementing the study of the contractile function of skeletal muscles. Similar method of
defining contractile activity of muscles was named a laser myography by authors.
This new noninvasive, quite sensitive method was made the basis of the development and implementation into the medical practice of a laser device (Laser
specklometer) aimed for the study of biomechanical characteristics of skeletal
muscles and microcirculation of skin. It is necessary to point out that the idea of
creation of a new generation diagnostic device on the basis of the principles of
speckle-optics, called laser specklometer, and its realization belongs to Leonid V.
Tanin. Nowadays, in the whole world, there are no analogs of this device that
allows studying noninvasively, remotely, with high sensitivity practically simultaneously the activity of muscles and microhemodynamics of skin in the process of
curing the diseases of peripheral and central nervous system. Thanks to the
speckle-optical diagnostics, it became possible to derive the data about functional
condition of skeletal muscle, root of spinal marrow and single nerve trunks that is
very important for defining the treatment tactics of this category of patients.
After graduating from Minsk State Medical Institute in 1993 and after clinical
studies on the basis of the Institute of Neurology, Neurosurgery and Physiotherapy
of the Ministry of Health of the Republic of Belarus, Andrei L. Tanin joins to the
conduction of these studies. He conducts studies in the field of biomedical optics
and defends a Candidate’s dissertation on the topic “Restoration of the functions of
peripheral nerves after neurography under the influence of laser hemotherapy.”
Andrei L. Tanin made a great contribution to the creation and development of the
brand new for medicine speckle-optical diagnostics and laser hemotherapy in the
treatment of diseases of peripheral and central nervous systems. Being a first-class
