Abstract: A method for improving neuromuscular performances is carried out by stimulus of nervous sensors during voluntary muscular contraction, transforming mechanical properties of the soft tissues, developing a high-pass mechanical filter, delivering a controlled and modulated mechanical force signal to be read by force isometric nervous receptors, and creates an illusory perception of the articular positioning. An apparatus for such use includes a transducer, a transducer fixing system, and a control panel, the transducer supporting a static load to transform biological tissues into a high-pass filter, imposing and sustaining a dynamic additive load on the muscular groups to be subjected to the treatment, thus producing a force signal propagation within the tissues, and transmitting the force signal to the patient; the control panel delivering an electric signal of pre-established frequency, and it being possible to modulate the amplitude of said frequency (to reach the deep muscle and its articulation).
