Application of a modified technique of correction of the functional state of the lower limb muscles in patients with achondroplasia provides control over the processes of adaptation of motor units to new anatomical and biomechanical conditions of locomotor system functioning. The technique utilizes mechanical impact on biologically active zones and points under conditions of transosseous distraction osteosynthesis. © 2013 Springer Science+Business Media New York.

The conclusion about a higher reserve potential of capillary bloodstream and variability of the acoustic properties of integumentary limb tissues in athletes is made based on studying the microcirculatory and anisotropic mechanical-acoustic properties of the limb skin in male athletes of high qualification (track-and-field athletes and wrestlers of the Greco-Roman style) at the age of 19-25 years and nonathletes at the age of 17-25 years. The revealed phenomena are based on the adaptive responses of the support-motor system to regular increased physical loads. A growth in capillary blood flow in the shank skin during a functional ischemic test is revealed to be higher in track-and-field athletes in comparison with the indicators in nonathletes. The reserve index of the capillary blood flow is 66.2% exceeded. The speed of propagation of a surface acoustic wave (SSAW) in the shank skin surpassed the corresponding SSAW parameters in the femoral integumentary tissue in the group of athletes and in the subjects of the control group. A similar excess of the SSAW index is observed in the forearm skin with respect to the shoulder parameters. The plastic reserves of the skin during change in the spatial position of a limb are revealed, which indicates the dynamic character of its viscoelastic properties during making movements. The mechanisms of the observed phenomena are supposed to be based on the structural distinctions of the skin and intensity of the capillary blood flow. © 2014 Pleiades Publishing, Inc.
