Expression function training after facial palsy can help you regain motor function of your face as soon as possible. Facial palsy training should be started after your facial palsy has entered the recovery phase, that is, if your facial palsy is still progressing and worsening, do not start this type of training for the time being. The training should be done in front of a mirror, using it to observe the symmetry of your facial movements. Asymmetries can be gently assisted with your hand. Note that it must be after the expression muscles make an effort to reach the areas that cannot be assisted by the hand. If the expression muscles do not make an effort, it is not very meaningful to move by hand alone.
