Assessing of respiratory muscular strength in patients with multiple sclerosis

Abstract

Introduction: Multiple Sclerosis (MS) is a disease of the central nervous system, affects young adults, and has motor abnormalities and respiratory diseases. Objective: To measure the respiratory muscle strength (RMS) of MS patients, comparing values of maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) and to correlate these values with fatigue. Methods: It was conducted assessment of FMR by manovacuometry in the early morning and late afternoon and fatigue with the Fatigue Severity Scale (FHS). Results: Comparing the predicted values of IP and EP, respectively, with morning and afternoon MIP, and MEP in the same periods, it was not possible to verify significant differences. Since the relationship between MIP and MEP late afternoon with FHS showed a strong correlation, r=- 0.70 and r=-0.69, in that order. Conclusion: PRmax be presented differently in the two periods although without significant difference, and the higher the score the HSF, the lower the FMR these patients.
