As a treatment, mastectomy is used, which releases variants in its procedure depending on the case. The problem lies in the fact that this procedure involves biomechanical alterations. Objective of the present work is to identify, through physical, muscular and functional exploration, the biomechanical alterations of the upper train present in post-mastectomy patients. Materials and methods of the present work are clinical histories, Daniels modifies muscle strength test. Postural test, functional semiological tests, plumb, grid and Microsoft Word and Excel. The present research work is of a deductive nature with a quantitative approach and descriptive scope, of non-experimental and transversal design. The population universe evaluated corresponds to 80 women post mastectomy. Results obtained show the presence of several biomechanical alterations where the scapular projection with 55% and the instability of the shoulder valued by the functional semiological test of the Groove with a positive 60%, followed by scoliosis and all the alterations she carries 53%. Conclusion, it is evident the presence of biomechanical alterations in postmastectomy women consistent with a period of considerable immobilization, which should be modified by performing a correct and early Physiotherapy protocol.esAcceso abiertoCorporación Universitaria LasallistaBiomecánicaEnfermedadesCáncer de mamaArticleinfo:eu-repo/semantics/openAcces
