Factors influencing respiratory muscle dysfunction among stroke survivors / 中华物理医学与康复杂志

ABSTRACT

Objective:To analyze the respiratory muscle functioning of stroke survivors and explore factors influencing it so as to provide references for clinical rehabilitation intervention.Methods:A total of 139 stroke survivors were randomly divided into a respiratory muscle dysfunction group and a control group based on the actual strength of their inspiratory muscles divided by the predicted strength. Beyond typical clinical data, information was collected about the subjects′ exercise habits. Balance ability was evaluated using the Fugl-Meyer assessment scale (FMA) and the simplified Berg Balance Scale (BBS). Multivariate logistic regression was used to analyze the factors influencing respiratory muscle dysfunction.Results:Among the 139 patients, 81 (58.27%) had respiratory muscle dysfunction. Univariate analysis showed that patients with stroke in the brainstem and dysphagia and those with poor FMA and BBS scores were at significantly greater risk of respiratory muscle dysfunction. Logistic regression analysis showed that dysphagia, FMA and BBS scores were factors independently predicting respiratory muscle dysfunction among stroke survivors, with dysphagia as a risk factor, and high FMA and BBS scores as protective factors.Conclusion:Some stroke survivors may have respiratory muscle dysfunction, and dysphagia is a risk factor, while the high FMA and BBS scores are protective.
