Relationship between invasive and non-invasive measures of inspiratory muscle electrical activation recorded from the left (a) and right (b) sides, calculated as the mean of the fSampEn oesEMGdi and sEMGlic signals. Data points represent median and interquartile range of the 120 respiratory cycles of the twelve study subjects for each load. The group mean correlation coefficients, ρ, of the twelve subjects were calculated using the Fisher z-transform. Dashed lines show the order of execution of the inspiratory threshold loads.
