Embouchure dystonia: a video guide to diagnosis and evaluation.
نویسنده
چکیده
BACKGROUND Embouchure dystonia is an unusual focal task-specific dystonia affecting the muscles that control the flow of air into the mouthpiece of a brass or woodwind instrument. The complexity of the embouchure and the relative rarity of the condition pose barriers for recognition and management of the disorder. METHODS Case review and video survey. RESULTS This paper presents four video compilations that illustrate the rich phenomenology of embouchure dystonia, in order to enhance recognition and diagnosis. CONCLUSION The phenomenology of embouchure dystonia is discussed.

متن کاملQuantification of instability of tone production in embouchure dystonia.
INTRODUCTION Musician's dystonia is a task-specific loss of voluntary motor control of the fingers or the embouchure. In contrast to pianists' dystonia, which can be objectively assessed based on movement kinematics and muscular activities, no objective quantitative measure has been established for embouchure dystonia. METHODS We focused on acoustic signals, and investigated, whether the fluc...
متن کاملFrom embouchure problems to embouchure dystonia? A survey of self-reported embouchure disorders in 585 professional orchestra brass players.
OBJECTIVES Data concerning embouchure problems in professional brass players are scarce. Embouchure problems can potentially lead to focal dystonia. The aim of this study was to investigate the frequency of distinct embouchure problems in professional brass players. Furthermore, the frequency of "cramping", a distinct symptom of embouchure dystonia, was evaluated in the context of established e...
متن کاملSensorimotor overactivity as a pathophysiologic trait of embouchure dystonia.
BACKGROUND Embouchure dystonia is a focal task-specific dystonia affecting the complex interplay of lower facial, jaw, and tongue muscles in musicians playing brass or woodwind instruments. Although it is highly disabling for affected patients, little is known about the pathophysiologic basis of this rare movement disorder. METHODS We therefore studied sensorimotor activation patterns during ...
متن کاملSensory mapping of lip representation in brass musicians with embouchure dystonia.
Embouchure dystonia is a focal task-specific disorder involving abnormal non-coordinated movements and involuntary muscle contraction around the mouth. In professional brass players it is often so disabling that patients have to limit or give up their occupation. We examined the somatosensory homuncular representation and measured gap detection sensitivity of the lips in eight former profession...
