Efeitos in vivo das ondas sônicas de baixa frequência no processo cicatricial

Physical therapy has an important role in soft tissue repair process, for improving its quality and velocity. Th e purpose of this work was to analyze the eff ects of sonic wave’s application in soft tissue repair process in animals. Twelve albino female wistar rattus norvegicus, 250-300 g, were used. Th e animals were divided into 4 groups (n = 3). One was considered Control Group. Th e Group I received 3 treatments, the Group II 7 and the Group III 10 sessions of sonic waves at 3333,33 Hz during 5 minutes. Th e results were obtained by a morphologic analysis of histological samples with an optic microscope. Th e presence or not of chronic and acute infl ammation, epithelium formation, granulation tissue, repaired soft tissue, crust, wound closure, and necrosis were analyzed. Th e obtained data show that the treatments groups reach faster soft tissue reparation and a better quality in relation with the control group. More researches are necessary to corroborate the sonic wave’s low frequency eff ects on repair process. Key-words: sound, wound healing, physical therapy.
