Aim of study: the aim of the study was to determine the influence of fascial and soft tissue treatment on respiratory efficiency and chest mobility of men and women between 22 and 54 years old. 

Materials and methods: Subjects between 22 and 54 y.o., vaccinated or healed from COVID-19 and without any other pathologies were recruited. Fascial and soft tissues manual treatment was made on mesentery’s roots, right pillar of diaphragm and ileo-cecal valve. Spirometry was executed before and after the treatment. Patients had been adequately instructed on how to make a spirometry. 

Results: FEV1 showed an average increase of 2% meanwhile FEF2575 showed an average increase of 14.38% [from 0.26% to 31.76%]

Conclusions: Although FEV1’s improvement is not indicative, there is an improvement in FEF2575 indicating better spontaneous return of the diaphragm to its resting state after the treatment. The treatment doesn’t act on filling because we have seen that the increase in FEV1 is not significant but it affects emptying so it could be interesting to evaluate how patients are able, after the treatment, to better empty themselves and, since better emptying is a prerequisite for better filling, whether and how the residual functional capacity improves. It is as if with the treatment we had made patients learn to better empty themselves, getting therefore a more elastic return of the diaphragm in its relaxed position. There is a gain except for smokers who always remain hyperinflated emphasizing then how the share of emphysema is already measurable for the smoker.
