BACKGROUND One third of patients with Parkinson's disease (PD) have mentioned "dysphonia" as their most debilitating communication deficit. Patient-based measurements, such as Voice Handicap Index (VHI) add necessary supplementary information to clinical and physiological assessment. There are a few studies about relation between VHI and disease severity in PD, although none of them showed any ...

The present study proposed a composite vegetation health index (VHI) derived from Leaf area index (LAI), Chlorophyll content (Cab) and equivalent water thickness (Cw) of wheat crop in Trans Gangetic Plains of India. The wheat growing areas of the study area were retrieved from time series 16 days MVC MODIS Enhance Vegetation Index (EVI) data. The LAI, Cab and Cw were retrieved from MODIS reflec...

VHI markets in the European Union are divers. This diversity arises from different historical patterns of development, variations in the rules and arrangements of statutory health care systems and discrepancies in national regulatory regimes. These factors underline the wide range of types of VHI on offer, levels of expenditure on VHI, levels of population coverage, types of insurer, mechanisms...

OBJECTIVE The aim of this study was to investigate the relationship between acoustic analysis and biopsychosocial implications of voice problems, evaluated by the Voice Handicap Index (VHI). MATERIALS AND METHODS The study comprised 120 female teachers with voice disorders, evaluated by videolaryngostroboscopy. 60.8% of this group were diagnosed as having functional dysphonia and 39.2% had dy...

AIMS To investigate the Voice Handicap Index (VHI), the health-related quality of life (HRQL), and the correlations between VHI and HRQL in laryngectomees. METHODS Forty-three laryngectomized persons participated (mean age 68;6 years, time since laryngectomy between 0;6 and 12 years). Evaluation of voice handicap was done with the VHI. HRQL was evaluated with questionnaires from the European ...

The Voice Handicap Index (VHI) is a widespread self-evaluation instrument for measuring the psycho-social handicapping effect of a voice disorder over 3 domains, the physical (P), the emotional (E) and the functional (F) domain. It consists of 30 items/statements to be scored from 0 to 4 . An abridged version (VHI-10) has been proposed and validated. Patients with SD report a severe psycho-soci...

Velvet Hand Illusion (VHI) is a tactile illusion that generates sensation of soft and smooth feelings. We propose to apply this illusion to develop the novel interface called Velvety Massage Interface (VMI). This system gives realistic sensation of being massaged on surface of sole of foot like reflexology. We conducted an experiment to verify if the VHI is generated to the sole of foot and if ...

BACKGROUND We conducted longitudinal voice evaluations in patients with early glottic cancer who underwent transoral laser microsurgery (TLM) to determine the time to stability. METHODS Twenty-five patients underwent TLM, including 13 limited cordectomies (type I and type II) and 12 extended cordectomies (type III to type IV). Multidimensional voice evaluations were performed before treatment...

The evaluation of diagnostics and therapies includes more and more subjective, i.e. emotional and social aspects. Focussing on the handicap experienced by dysphonic patients, the Voice Handicap Index (VHI) has previously been found to be of significant clinical and scientific value for different voices. In this study the VHI questionnaire was applied to demonstrate the voice handicap of 20 male...
