1. A method for extracting a neural respiratory drive measure of a user, the method comprising:
non-invasively obtaining a first EMG signal from a plurality of electrodes, at least two of the plurality of electrodes being disposed contralaterally;
processing the first EMG signal with a first processing sequence to produce a processed EMG signal;
processing the first EMG signal with a second processing sequence to produce a surrogate respiration signal, the second processing sequence and the first processing sequence being parallel to and independent from one another, wherein the surrogate respiration signal is obtained only from the first EMG signal;
detecting inhalations of the user based on the surrogate respiration signal;
time aligning the detected inhalations with the processed EMG signal; and
determining the neural respiratory drive measure based on the time aligned detected inhalations and processed EMG signal.
