Effect of Shock Wave Therapy Without Biological and Immuno-histochemical Analysis.

Informative Summary: Extracorporeal shockwave therapy (ESWT) is a new method for treating aesthetic disorders within the field of aesthetic medicine, its mechanisms of action and physiological effects promise to combat localized fat accumulation, improve skin appearance, favor neocolagenesis and neovascularization. There are currently few studies on ESWT that can claim this benefit, but therapy has been shown to be safe and does not generate adverse reactions to individuals. Objective: To evaluate the physiological effects and mechanisms of ESWT acting on subcutaneous adipose tissue and adjacent structures through an experimental study. Methods: A randomized experimental clinical study will be performed in 30 women with grade I, II and III obesity who participated in the multidisciplinary preoperative preparation group for bariatric surgery with previously scheduled surgery. Participants will receive ESWT application within hours of surgery, or in the weeks prior to bariatric surgery, during the surgical procedure a small sample of subcutaneous adipose tissue will be taken for histological and immunohistochemical analysis. Hypotheses: Through histological and immunohistochemical analysis of the subcutaneous adipose tissue sample, the investigators can identify which real physiological effect and mechanism of action the ESWT has on subcutaneous adipose tissue, epidermis and adjacent structures, thus confirming the benefits of therapy. Statistical analysis: A descriptive analysis of the results obtained in the histological analysis will be performed initially, with frequency tables for categorical and descriptive variables (mean, standard deviation, median, minimum and maximum values) for continuous or numerical variables. In order to compare the main variables between groups and session number, the analysis of variance (ANOVA) will be used for repeated measures. For comparison between groups the Tukey test will be used. The significance level adopted for the stat
