Evaluación de los efectos de un dispositivo de entrenamiento de los músculos inspiratorios sobre la oxigenación muscular y la activación neuromuscular de los músculos respiratorios.

Abstract

Objetivo: Comparar los cambios en la actividad electromiográfica y oxigenación muscular periférica de los músculos intercostales, en su condición de musculatura accesoria a la respiración, en pacientes con EPOC durante la realización de un test de marcha de 6 minutos (TM6M) con y sin el uso de un dispositivo FeelBreathe (FB). Material y métodos: Se seleccionaron a 20 sujetos diagnosticados de EPOC a los que se les realizaron dos TM6M separados al menos por 60 minutos. Aleatoriamente, cada uno de los pacientes realizó dos TM6M, uno usando el dispositivo FB y el otro sin FB (SFB) y se midieron durante la realización de ambos TM6M la actividad electromiográfica (EMG) obteniéndose la raíz de la media cuadrática (RMS), y por otro lado la oxigenación tisular de los músculos intercostales a través de la variable de oxihemoglobina (HbO2). Resultados: No hubo diferencias significativas en la distancia recorrida en ambos TM6M con FC a SFB. Tanto la RMS como la oxigenación tisular mostraron valores similares entre la condición FB vs. SFB al final de ambas pruebas (32,26 ± 101,94 μV vs 28,25 ± 87,02 μV; p = 0,16 y 70,63 ± 18,80 vs 70,74 ± 16,77; p = 0,975 respectivamente). Conclusiones: El estímulo de trabajo de la musculatura intercostal durante el TM6M con el dispositivo FB no compromete la aparición de la fatiga temprana por un exceso de activación o disminución de la oxigenación de dichos músculos al nivel de intensidad del TM6M.
