laser blood irradiation, multivitamins, massage, mechanotherapy.
It was found out that intravenous laser blood irradiation had a more apparent
positive therapeutic effect than medication, causing the optimization of microcirculation in the damaged tissues, which helps to improve the state of tonic muscle fibers
and has a positive impact only on the frequency of the speckle-optical indices of
contractile properties.
The studies of microhemodynamics of skin of healthy people were carried out
at different functional states. At the same time, the frequency range of the intensity
fluctuations of the surface blood flow is in the range from 100 to 10 kHz. As a model
of disorders of skin microhemodynamics, here a hypoxic test, cold test (application
of ice to the skin of the back of the hand to reduce the skin temperature up to 19
°C) and infriction of “Finalgon” ointment, which causes congestion, were used.
For the purpose of conducting a hypoxic test in the tonometer cuff on the top of the
shoulder, the pressure was raised up to 200 mm Hg; during this process in the range of
frequencies of 125–2000 Hz the reduction of all amplitude–frequency characteristics
of a spectrum was set. During the restoration of blood flow, the speckle-optical
indicators increased, reaching the norm values. The changes of spectrum power under
conducting the test “norm—the cold—hyperemia,” the values of which decreased
under hypothermic test and increased under hyperemia, are presented in Fig. 5.55.
The tonic tension and contractile function of skeletal muscles were studied at
30 healthy people using methods of speckle-optics. The increase of the average
frequency of spectrum of various muscle groups at their maximal voluntary contraction in comparison with the condition at rest was observed (Fig. 5.56). The power of
spectrum connected with the spectrum amplitude also appeared to be a rather informative parameter of functional muscle condition. The method of speckle-optical
myography made it possible to discover and assess objectively the peculiarities
of functional condition of muscles during the conduction of test using isometric
