A clinical essay with prospective characteristics in which there was no intervention. Their objective characterizing profiles of patients admitted to Santa Casa de Presidente Prudente referred for taking physical therapy and to evaluate the effect of therapy on maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP) and palmar prehension (FPP). There were 93 individuals admitted to undergo physiotherapy. Each volunteer was asked in bed and tested for dynamometry to assess a palmar prehension test and manometer to obtain the maximum inspiratory and expiratory pressures. It was used descriptive statistics, qui-square, t-student, and pearson correlation, using the BioEstat 5.0. program. Cancer was the predominating cause of hospitalization and the most prevalent risk factor was sedentary lifestyle. About MIP, MEP and FPP there was no significant decrease considering the time of admission. There were no changes in respiratory muscular strength and palmar prehension during the time spent in hospital for patients who underwent physiotherapy, which is capable of preventing functional alterations that are imposed to the patient as an effect of immobility and bed restriction.
