Introduction Many postural problems derive from excessive fascial tension, which creates muscle, tendon and osteo-articular problems. By rebalancing the fascia, multiple postural-functional problems can be resolved [1]. The mechano-sonorous vibration is nothing more than a mechanical vibration, which uses pressure-depressor air cones to stike the skin and send a stimulus to the central nervous system [2], through the deformation of the high threshold mechanical receptors (Pacini corpuscles), according to the "all or nothing" technique, using the Wave Meccanica Quadra. Aims The aim of the study was to identify if the anteriorized posture can be influenced by saction on the abdominal peritoneal component because here there are strong tensions, which can accentuate the attitude described above [3]. Method Children between the ages of 6 and 12 were included, without any previous pathology and with an anteriorized postural attitude. Evaluation were performed with baropodometric examination and instrumental examination of the lateral/lateral Barre vertical. For the stimulation of postural receptors (Pacini corpuscles), the EVM instrument from Endomedica was used, which emits mechanical sound waves, focused in two specific points, lateral to the navel. After 15 minutes of vibrations at 250hz, the subjects were re-examined with the same tests. Results Of the 18 patients examined, we immediately notice that, after the application of the mechanical sound vibrations, there was a change/variation in posture. Almost all subjects had an improvement in the positioning of the head, more on the same axis, except for a case in which the priority component (made with subsequent tests) was found to be type cranial and temporomandibular joint deviation. Conclusions We can conclude that a superficial fascial abdominal relaxation, by means of mechanical-sound vibrations, leads to a sensitive postural variation and a greater momentary rebalancing of the patient.
