This master’s thesis presents the essential characteristics of focal dystonia in brass players, the neurological mechanisms behind its development, and the typical symptoms observed in musicians who perform highly repetitive and specialized motor tasks. Special emphasis is placed on the embouchure, one of the most complex and sensitive motor systems in brass playing, making these musicians particularly vulnerable to the disorder.
The thesis analyses the main risk factors, such as excessive automatization of technique, prolonged repetition of specific movements, excessive mouthpiece pressure, psychological stress, and improper posture. Therapeutic approaches discussed include sensorimotor retraining, physical therapy, biofeedback, motor control therapy, ergonomic adjustments, and targeted use of botulinum toxin. Considerable attention is given to pedagogical strategies, which play a crucial role in restoring healthy technique and achieving long‑term playing stability.
The work also highlights the importance of prevention, particularly within music pedagogy and educational institutions, as early recognition of symptoms and proper practice habits significantly reduce the likelihood of developing the disorder. Despite its challenging consequences, focal dystonia is not irreversible; with an interdisciplinary approach and appropriate professional support, significant improvement or complete recovery is achievable.
