The effect of subthalamic deep brain stimulation on gait coordination and freezing of gait in patients with Parkinson's disease is incompletely understood. The purpose of this study was to investigate the extent to which modulation of symmetry and coordination between legs by subthalamic deep brain stimulation alters the frequency and duration of freezing(More)
OBJECTIVES To study the prevalence of psychiatric comorbidity assessed by a structured clinical interview in patients with spasmodic dysphonia (SD) compared with patients suffering from vocal fold paralysis (VFP). METHODS In 48 patients with SD and 27 patients with VFP, overall psychiatric comorbidity was studied prospectively using the Structured(More)
Multi-channel auditory evoked potentials (AEP) were recorded before and after cochlear implantation (CI) from a patient suffering from severe high frequency hearing loss with residual, but highly fluctuating hearing around 250 Hz. Immediately after CI activation early components of the N1 were present. Later N1 components developed during the use of CI. The(More)
STATEMENT OF PROBLEM The insertion of prosthodontic restorations often leads to speech defects, most of which are transient but nevertheless a source of concern to the patient. For the dental practitioner, there are few guidelines on designing a prosthetic restoration with maximum phonetic success. PURPOSE This study investigated the effect of different(More)
Clicked-evoked otoacoustic emissions and automated auditory brainstem response are both considered appropriate hearing screening tools. The aim of this study was to compare their practicability with respect to test duration. In the first part of the study, clicked-evoked otoacoustic emissions were recorded in 388 healthy infants on the newborn ward in the(More)
It is well known that alterations to the oral cavity caused by dental prostheses may affect speech articulation, although influences on the voice are not assumed. In addition to the vocal fundamental frequency, vibrations of the vocal chords generate overtones. Through the shape of the larynx and the upper airway, resonances and antiresonances are formed,(More)
One of the most frequent causes of sensorineural hearing loss in childhood is damage to outer hair cells of the cochlea. The presence of otoacoustic emissions, generated by outer hair cells, provides evidence for normal hearing. This finding, however, may give rise to false reassurance, because even severe hearing loss, localized behind the cochlea, can be(More)
Many factors are thought to be responsible for misarticulation. Maxillomandibular or dental irregularities play an important role as one of these factors. Correlations between morphological changes in dental status and speech disorders are well known, but different opinions are discussed in the literature. A reciprocal relationship between dysfunction and(More)
