RESUMEN
OBJECTIVE: Stroke often leads to abnormalities in muscle tone, posture, and motor control that may compromise voluntary motor function, thus affecting the motor control required for maintaining the synergy of both peripheral and respiratory muscles. To evaluate respiratory muscle strength, pulmonary function, trunk control, and functional independence in patients with stroke and to correlate trunk control with the other variables. METHODS: This was a cross-sectional study of patients diagnosed with stroke. We assessed respiratory muscle strength, trunk control as assessed by the Trunk Impairment Scale, spirometric variables, and the Functional Independence Measure. RESULTS: Forty-four patients were included. Pulmonary function and respiratory muscle strength were significantly lower than predicted for the study population, and the mean Trunk Impairment Scale score was 14.3 points. The following significant correlations were found between the variables: trunk control vs. maximal inspiratory pressure (r = 0.26, p < 0.05); trunk control vs. forced vital capacity (r = 0.28, p < 0.05); trunk control vs. forced expiratory volume in one second (r = 0.29, p < 0.05), and trunk control vs. the Functional Independence Measure (r = 0.77, p < 0.05). CONCLUSION: The present study showed that respiratory muscle strength, pulmonary function, functional independence, and trunk control are reduced in patients diagnosed with stroke.

RESUMO Acidente vascular cerebral (AVC) frequentemente leva a anormalidades no tônus muscular, postura e controle motor que podem comprometer a função motora voluntária, afetando o controle motor necessário para manter a sinergia dos músculos periféricos e respiratórios. Objetivo Avaliar a força muscular respiratória, a função pulmonar, o controle do tronco e a independência funcional em pacientes com AVC e correlacionar o controle do tronco com as demais variáveis. Métodos Este foi um estudo transversal, incluindo pacientes diagnosticados com AVC. Avaliamos a força muscular respiratória, o controle do tronco avaliado pela escala de comprometimento de tronco, as variáveis espirométricas e a medida de independência funcional. Resultados Quarenta e quatro pacientes foram incluídos. A função pulmonar e a força muscular respiratória foram significativamente menores do que o previsto para a população estudada, e o escore médio do escala de comprometimento de tronco foi de 14,3 pontos. As seguintes correlações significativas foram encontradas entre as variáveis: controle do tronco vs. pressão inspiratória máxima (r = 0,26, p <0,05); controle do tronco vs capacidade vital forçada (r = 0,28, p <0,05); controle do tronco versus volume expiratório forçado no primeiro segundo (r = 0,29, p <0,05) e controle do tronco vs. medida de independência funcional (r = 0,77, p <0,05). Conclusão O presente estudo demonstrou que a força muscular respiratória, a função pulmonar, a independência funcional e o controle do tronco estão diminuídos em pacientes diagnosticados com AVC.
