Investigation of the Instant Effect of Rocabado Exercise

In this study, surface Electromyography (EMG) was employed to assess the electrical activity of the masseter muscles. Surface EMG is a physiological measurement technique that allows for the recording of electrical potentials generated by muscle fiber depolarization through non-invasive electrodes placed on the skin. This method is widely accepted for objectively determining muscle activation levels and timing, enabling the quantitative analysis of changes in masseter muscle activity during the performance of various Rocabado exercises in this study. The validity and reliability of the EMG device utilized (Noraxon USA Inc., Scottsdale, AZ, USA) have been established in the literature.
