Posture and movement influence the entire body, including the orofacial system and verbal communication. Function-oriented speech therapy systematically demonstrates this influence and derives consequences for promising therapy. The multidisciplinary author team presents the functional relationships between the orofacial and musculoskeletal systems for speech therapists in training or continuing education, such as anatomy and physiology, insights into oral surgery, and explanations of orofacial, pharyngolaryngeal, and musculoskeletal functions, particularly posture and movement. The practical section covers, among other topics, body-oriented speech therapy, functional kinetics, Klein-Vogelbach, and function-oriented myofascial therapy. Numerous case studies illustrate the content. Discover a prime example of lived interdisciplinarity with function-oriented speech therapy.
