Investigation of the relationship between the diaphragm muscle relaxation therapy, voice emission and postural stability in amateur and professional singers of Academy of Music – preliminary study

The present study aims at presenting the impact of manual diaphragm relaxation therapy on voice emission tested in an anechoic chamber and changes body posture during singing using Zebris posturographic pedobarographic platform. A pilot three cases has been conducted (patient 1 – male aged 21, student 2nd year Academy Music Krakow, patient 2 34, with more than 25 years choral advanced musical experience, 3 female 24, around 10 experience primary school graduation). An original survey questionnaire was used, enabling determination problematics associated profession singer. platform (Zebris) used that revealed deviations scenic movement (by performing appropriately developed repertoire). Subsequently, a examination carried out Department Mechanics Vibroacoustics, AGH University Science Technology. Directly after examination, examined individual subject to lasting several minutes. applied fascial techniques for consisted implementation prolonged stretching myofascial complex use low load. After therapy, testing aforementioned methods repeated. refers function parameters. In 2, 15 parameters improved. analysis above results showed variability before such as Fo, Jitt Shim. case value parameter decreased by almost half, while Shim about 40 % therapy. However, were not observed 3. It may be influenced many factors, stress or worse disposition day examination. presented preliminary expands knowledge awareness ventilatory muscles singing, which result enhanced efficiency working voice. future it is planned bigger group students Krakow control group.
