[Electromyograph unit for automated analysis of interference electromyogram].

Electromyograph unit for an automated analysis of the interference electromyogram is intended for quantitative analysis of the interference electromyogram, drawn aside by a needle electrode. The offered unit is very simple in design and allows to get the objective data of the functional state of the neuromuscular system.

[Contractile properties of crural muscles in patients with post-stroke movement disorders].

Disorders were detected in the contractile properties of tibial muscles in the patients with stroke-related motor disturbances depending on the degree of functional deficit. Maximum slow-down in the fast muscles and speeding of the slow ones was detected within half-year since the stroke.

[Restoration of muscle contractile properties after partial and complete denervation].

The subject of this experimental study was the isometric contractile properties of rat tibialis anterior muscle, number and average size of the motor units as well as type content and type-grouping of muscle fibres according to SDH activity in the same muscle after total and partial denervation (crushing the sciatic nerve and L4). It has been shown that in the process of reinnervation after total and partial denervation, quantitative differences with the general tendency in the dynamics of restoration of contractile properties of the whole muscle are found at different dynamics of restoration of electromyographic and muscle histochemical characteristics of motor units.
