Abstract: A system and method for the non-invasive measurement of tone, state of tension, biomechanical or viscoelastic properties of soft biological tissues includes a testing-end, an actuator arranged to apply a force to the testing-end, and a sensor to sense movement of the testing-end. A signal generating circuit supplies a control signal to the actuator so the biological tissues are subjected by the testing-end to a load, including means to adjust the signal provided by the signal generating circuit in accordance with the component of weight acting through the testing-end onto the biological tissue so that the load to which the biological tissue is subjected is constant. An impulse signal generating circuit supplies an impulse signal to the actuator so the biological tissue is subjected by the testing-end to a mechanical deformation. In use the soft biological tissue is subjected first to the constant load, and then to the impulse signal; and the consequent movement of the biological tissue is then registered.

Abstract: A device and a method for simultaneous recording, in real time, parameters characterising the mechanical tension, elasticity, dynamical stiffness, creepability and mechanical stress of soft biological tissue are provided. By means of the myometer, a constant external pre-pressure is created, independently of the device's position, between the tissue and the testing end of the device. Next, the tissue is subjected to a short-term external dynamic influence. A mechanical change in the shape of the tissue and its mechanical response are registered as a graph of the tissue's oscillations. For calculating the parameters, a time span on the graph is used which involves an oscillation period from the beginning to the end of the effect on the tissue plus its subsequent first 1.5 self-oscillation period. This enables recording and data-processing to be carried out simultaneously as well as statistically significant estimates to be made in real time.
