The bassoon is a demanding double-reed woodwind instrument requiring exquisite control of airflow and air pressure to the reed to produce desired tonal characteristics. Little information is available from direct visualization of the vocal tract and larynx of the bassoonist while playing. Of particular interest is the mechanism(s) of vibrato. This study was(More)
27 undergraduate students participated in an experiment on EMG biofeedback. Three groups were employed (visual feedback, audio biofeedback, and control) to determine which group learned to reduce frontalis muscle tension more quickly. All subjects were trained during a 30-min. period for five days. The time consisted of a 10-min. baseline and a 20-min.(More)
There is little reported evidence regarding the reliability of temporal and physiologic features of infant swallowing from videofluoroscopic swallowing studies (VFSS). The purpose of this retrospective study was to determine a reliable set of temporal and physiologic features from infant swallowing that can be measured from analysis of VFSS. Temporal and(More)
OBJECTIVES/HYPOTHESIS This study evaluated the hypotheses that sentence production by speakers with adductor (AD) and abductor (AB) spasmodic dysphonia (SD) may be differentially influenced by consonant voicing and manner features, in comparison with healthy, matched, nondysphonic controls. STUDY DESIGN This was a prospective, single blind study, using a(More)
Aging of the larynx is characterized by involutional changes which alter its biomechanical and neural properties and create a biological environment that is different from younger counterparts. Illustrative anatomical examples are presented. This natural, non-disease process appears to set conditions which may influence the effectiveness of botulinum toxin(More)
The pattern of gross displacement of the vocal fold during adduction and abduction was studied in 4 adult fresh human larynges (2 males and 2 females). Markers were placed on specific sites along the edge of the vocal fold. Preliminary observations showed upward and lateral movement of the free edge during abduction. The vocal fold as a whole glides into(More)
The effects of Möbius syndrome (MoS) on the functioning of the peripheral speech and hearing mechanisms has not hithertofore been described, to my knowledge. Speech and hearing function of an 8-year-old MoS speaker was studied. Data were obtained from several sources. These included: electromyography of the facial muscles, physical examination of the(More)
