N2 - Studies addressing training-induced neuroplasticity and interrelationships of the lip, masseter, and tongue motor representations in the human motor cortex using single syllabus repetition are lacking. This study investigated the impact of three consecutive days of PaTaKa oral motor task (OMT) training on corticomotor control of the lips, masseter, and tongue muscles in young healthy participants. Transcranial magnetic stimulation was applied to elicit motor evoked potentials (MEPs) in the assessed muscles at baseline and after OMT. The oral diadochokinetic (DDK) rate of PaTaKa syllabus repetition was also recorded. The OMT training increased DDK rate (P < 0.01) and MEP amplitude of the lip, masseter, and tongue (P < 0.001). Our findings suggest that three consecutive days of repeated PaTaKa OMT can induce neuroplastic changes in the corticomotor pathways of orofacial muscles, and it may be related to mechanisms underlying the acquisition of oral fine motor skills with short-term training.
