The effectiveness of myofunctional therapy depends not only on the quality of the individual exercises but also considerably on the patient's compliance. In this paper, factors are described which may decisively influence patients motivation to cooperate during treatment. Based on experience in dealing with patients, clinical studies and psychological knowledge, theoretical approaches to patient motivation are discussed, namely aspects of verbal communication, control, reward, behavior agreement as well as verbal self-control and self-reward.
