Abstract
The purpose of this study was to evaluate the inspiratory and expiratory muscle strength of individuals affected by stroke and to compare it with the predicted values in the literature considering their corresponding age. Respiratory muscle strength was evaluated in 22 elderly people who had sequels of stroke, four with right hemiparesis, 16 with left hemiparesis and two with bilateral, of ages ranging from 34 to 82 years. The collected data were submitted to statistical analysis using a Mann–Whitney test to evaluate if there was a significant difference in the average data collected when compared with a mean of the predicted data in the literature. Fourteen men and eight women were evaluated, who obtained mean values of 71.85 cmH2O and 57.75 cmH2O, respectively, for a maximal inspiratory pressure (MIP), and when compared to the predicted values for men and women, 105.41 cmH2O (p-value 0.0019) and 80.57 cmH2O (p-value 0.00464) were significantly lower. For a maximal expiratory pressure (MEP), the mean value obtained for men was 62.28 cmH2O and 49.5 cmH2O for women, whereas the predicted values in the literature were 114.79 cmH2O (p-value < 0.0001) and 78, 46 cmH2O (p-value 0.0059), respectively. In the statistical analysis, it was possible to notice that the studied population did not reach the predicted age indexes and that there was a significant difference between the median columns. In conclusion, there is a weakness in the respiratory muscles of hemiparetic men and women due to stroke.
Highlights
Stroke is clinically defined as an acute neurological dysfunction of vascular origin and is classified as the third most fatal disease in several countries worldwide [1,2]
The collected data were compared to the values found in literature according to individuals of similar age and gender, and the results revealed predicted values of maximal inspiratory pressure (MIP) for men of 105.41 cmH2 O and similar age and gender, and the results revealed predicted values of MIP for men of 105.41 cmH2O
The main objective of this study was to evaluate the inspiratory and expiratory muscle strength of stroke patients and compare with the values predicted in the literature considering the corresponding age
Summary
Stroke is clinically defined as an acute neurological dysfunction of vascular origin and is classified as the third most fatal disease in several countries worldwide [1,2]. It can be explained as a vascular alteration that acutely or intermittently weakens blood flow in the brain, caused by arterial obstruction (ischemic stroke) or its rupture (hemorrhagic stroke) [3]. The nervous system, when affected by a pathology, can cause a physical and mental disability that, leads to some sequelae, such as paralysis, sensory and muscle tone changes, general.
