Objective: The study objective was a comparative assessment of power characteristic of respiratory muscles in 72 patients with ischemic stroke in different combinations of comorbidity.
Methods: Levels of maximal inspiratory and expiratory pressure in oral cavity, maximal speed of its rate of its rise during inspiration and expiration, the level of intranasal pressure, as well as their ratio indices.
Results: Decrease in strength of expiratory and inspiratory respiratory muscles is recorded in early and late rehabilitation periods of ischemic stroke, the severity of which depended on the severity of neurological impairment and clinical variant of comorbidity. Hypofunction of accessory inspiratory muscles was common for patients suffered a stroke in congestive heart failure; a diaphragmatic dysfunction of respiratory muscles prevailed in patients with metabolic syndrome. A decrease of expiratory muscles strength prevailed in the combination of ischemic stroke with chronic obstructive pulmonary disease of 1 and 2 stages.
Conclusions: The severity of comorbidity pathology significantly affects the strength of respiratory muscles. The interrelation of the strength characteristics of muscle tissue with the parameters of bronchial patency, smoking index, skeletal muscle mass and the severity of shortness of breath is noted.
