Effekt der kontralateralen Stimulation auf evozierte otoakustische Emissionen bei akutem Hörverlust*
1994
23 patients with unilateral hearing loss and presence of TEOAE on both ears were examined with regard to the association between contralateral acoustic stimulation and evoked otoacoustic emissions. Contralateral white noise of 40 dB HL, 50 dB HL and 60 dB HL decreases the amplitude of TEOAE both at the ear with and without hearing loss. In comparison with a group of subjects with normal hearing, the decrease in the amplitude of TEOAE was less in the group of patients with hearing loss. Two paradoxical cases were found with an increase in the TEOAE amplitude in the ear with hearing loss during contralateral stimulation. It is assumed that impairment of the efferent synapses on the outer hair…
Bifocal Stimulation in Patient with Congenitally Corrected Transposition of Great Vessels
2011
Congenitally corrected transposition of the great vessels (CCTGV) is a rare congenital heart defect associated with multiple cardiac morphological abnormalities and conduction defects. Complete atrioventricular (AV) block occurs in 30% of patients and it may be present at birth or develop later with a rate of 2% per year; moreover, a systemic right ventricle is frequently characterized by heart failure in adult life. We used a bifocal cardiac stimulation for a young woman affected by CCTGV and atrioventricular Mobitz 2 and 2:1 block, considering structural, anatomic condition, and the high rate of pacing she underwent.

Sacral neuromodulation for treatment of lower urinary tract dysfunction
2000
Despite initial reservations, sacral neuromodulation has begun to develop as a new therapeutic tool for the treatment of lower urinary tract dysfunction. It bridges the gap between conservative treatment options and highly invasive procedures, such as urinary diversion. At present, there are no clinical variables that can reliably predict the efficacy of neuromodulation in an individual patient. All patients, regardless of indication, must therefore undergo a test stimulation before they can be offered chronic sacral neuromodulation with an implanted system. Evaluations in various clinical trials have confirmed that sacral neuromodulation, based on unilateral sacral foramen electrode implan…
Comparison of TMS-induced arm acticvation and upper limb functional tests in hemiparetic stroke
2013
Stroke has a major impact in the total cost of healthcare in the Western world as stroke is the most common cause of long-term disability [1]. In attempts to enhance motor recovery after stroke effective treatment strategies have been developed in recent years. Appropriate evaluation of the intervention programs requires comprehensive and accurate assessment of the residual abnormal function. In the present study we compare two well-known clinical functional scoring tests developed for the assessment of hemiparetic upper limb function due to stroke and navigated transcranial magnetic stimulation (nTMS), which measures involuntary target muscle response to cortical stimulation. The aim is to…
Multifocal Repetitive Transcranial Magnetic Stimulation—A Novel Paradigm in Migraine Treatment
2019
Transcranial Magnetic Stimulation (TMS) is a non-invasive brain stimulation method used for analyzing structural and functional interactions in brain, assess cortical reactivity, and map functionally relevant brain regions inducing a controlled current pulse in a defined region of the cortex. From a clinical point of view, TMS has shown promising results in the therapeutic approach in a large number of psychiatric and neurological conditions such as anxiety, depression, OCD, headache disorders—migraine being one of the most encountered, etc. In patients with migraine, the pharmacologic therapy can be divided in abortive and preventive treatment of the attack. Usually the treatment is starte…
Effects of a Vibro-Tactile P300 Based Brain-Computer Interface on the Coma Recovery Scale-Revised in Patients With Disorders of Consciousness
2020
Persons diagnosed with disorders of consciousness (DOC) typically suffer from motor and cognitive disabilities. Recent research has shown that non-invasive brain-computer interface (BCI) technology could help assess these patients’ cognitive functions and command following abilities. 20 DOC patients participated in the study and performed 10 vibro-tactile P300 BCI sessions over 10 days with 8–12 runs each day. Vibrotactile tactors were placed on the each patient’s left and right wrists and one foot. Patients were instructed, via earbuds, to concentrate and silently count vibrotactile pulses on either their left or right wrist that presented a target stimulus and to ignore …
Neuroplasticity in the Adjustment to Blindness
1999
Loss of vision due to injury to the eyes results in deafferentation of very large areas of the human cortex and poses striking demands on other sensory systems to adjust to blindness in a society that heavily relies on vision. Blind subjects need to extract crucial spatial information from touch and hearing. To accomplish this, plastic trans-modal changes appear to take place by which a larger area of the sensorimotor cortex is devoted to the representation of the reading finger in Braille readers, and parts of the former visual cortex are recruited for the processing of tactile and auditory information.
Electronystagmography in the diagnosis of central vertigo.
2011
Objective: Determine the efficacy and applicability of electronystagmography (ENG) testing in the differential diagnosis between peripheral and central vertigo, through the visual-vestibular interaction test, in patients with vertigo.Method: Patients were submitted to ENG recording. Patients sat on a rotatory chair, which was placed in the middle of a rotary rotatory cylindrical chamber. The rotatory chamber was driven by a direct current engine, which turned it clockwise and counterclockwise, and its internal area was covered with 32 black vertical contrast.Results: All patients underwent rotatory vestibular stimulation by Stop test (VOR), optokinetic stimulation (OKN), and contemporary ro…
