FIGURE 6.

Overview of the execution of the repeated PaTaKa training in an OMT. Details of the lips, masseter (intramuscular recordings), and tongue electromyography (EMG) activity were recorded in a block model providing in total a 15 s of OMT as follows: the participant was instructed to start with a 5‐s rest block and after pronouncing each predefined Pa, Ta, and Ka single syllable with an intersyllabic interval of 1‐s of a rest block alternating by 1‐s of a task block, with a duration of 10‐s. The zero amplitude indicates the repositioned threshold from the intersyllable pauses and the syllable with increased peak intensity. The black arrow indicates the EMG activity. The first arrow (above the line) points to the onset, and the second arrow (below the line) points to the mid‐range activity. Contraction refers to a voluntary activation of the indicated muscle (as a control) either as a tonic contraction (lips and tongue) or as a repetitive dynamic contraction ~1 Hz (masseter).
