[Electromyographic response to progressive activation of functional appliances]. / Risposta elettromiografica alla attivazione progressiva delle apparecchiature funzionali.

The Authors, according to the literature, carried out an electromyographic study on young Class II patients. Muscolar activity was studied during rest and with Frankel's functional regulator in different conditions of activation. Analysis of obtained results supports the author's idea of an individual activation of the functional appliances.
