be applied during conducting of myographic studies in neurosurgery, restoration
surgery, muscle tone determination.
As a result of the conducted studies the most sensitive to the changes of muscles,
physical condition spectrum parameters, namely its power and medium frequency,
were detected. It was found out that with an increase of isotonic load applied to the
biceps muscle of arm, power and medium frequency of a spectrum increase up to
80% from maximal effort developed by a patient. Further increase of the load leads
to the decrease of muscle vibrational activity, which is confirmed by the decrease of
power and medium frequency of a spectrum. Analogous results were described in the
literature for sound myography. Bioelectrical muscle activity grows proportionally
to the increase of isotonic load up to maximal effort developed by a muscle. Thereby,
as the studies showed, the laser specklometer allows receiving additional information
about vibrational function of a muscle, which cannot be obtained with the help of
electromyography.
A series of studies of vibrational characteristics of human skeletal muscles at
different physical exercises was conducted. For every given constant load, 10 spectra
were registered in the same conditions. Statistical processing of the results was
carried out. The dependences of informational parameters of spectra, namely the
area under the curve and average frequency of the physical load intensity, were
made. It was shown that in average the obtained curves increase monotonically
with the growth of loads up to 80% from effort maximally developed by a patient.
With the help of speckle-optical methods, it was also found out that at different
degrees of manifestation and distribution of muscle fixation in patients with reflectory
and radicular syndromes of lumbar osteochondrosis there is observed the difference
of speckle-optical indicators of muscle activity of paravertebral muscles both at
the level of damaged segment at the sore and intact side and in cases of spread
myohypertonicity at overlying areas of chest.
9. The informative parameters of fluctuation spectra of intensity of dynamical
speckle-field, which reflect biophysical processes occurred in the skin blood
flow, which can also characterize pathophysiological changes in the tissues under
studies, were detected. The possibility of study of surface blood flow in the limited
zone allowed determining its segmental differences along the spine in patients
with vertebral pathology. The increase of the frequency of spectra fluctuations
of the intensity of speckle-field in the zone of damaged vertebral–locomotive
segment is accompanied by the growth of the temperature in this area and indicates the intensification of skin microhemodynamics. This phenomenon can be
the reflection of dyscirculatory processes, which occur in located deeper peridisk
tissues, disks, when sanogenetic reactions prevail also in patients with dystrophic
changed disk in order to reduce the disorders of metabolism, microcirculatory
processes are intensified.
The dynamics of skin blood flow of lower limbs in patients with neurologic manifestation of lumbar osteochondrosis corresponded to the change of high-frequency
fluctuation intensity spectra of speckle-field. Here shifts of regional blood flow on the
lower limbs, which were detected by reovasography and which reflect angiospastic
