Goal:
To determine the normality per age group of the "Echelle du Handicap lié aux Troubles de l'Equilibre et aux Vertiges" (EHTEV) French version of the "Dizziness Handicap Inventory" (DHI) and to assess the effect of sex on the scores and the reproductibility.
Subjects And Methods:
The normative scores and the effect of the sex were determined in a group of 120 subjects without any instability disorder. Sixty-three women and 57 men, aged 20-79 years were graded by age section of 10 years. After 8-10 weeks the same questionnaire was submitted again to 47 individuals of this same group to assess the reproductibility.
Results:
The scores of the instability showed that handicap increased with the age. The mean score for the 50-79 year-old group is almost four times greater that of the 20-49 years old. Correlation between scores and age is 0.70 for physical handicap, 0.76 for emotional handicap, 0.69 functional handicap and 0.83 for global score. There is no significant influence of sex. The reproductibility coefficient is 0.98.
Conclusion:
The scores of the EHTEV increase with age. There is no significant influence of sex on scores and the coefficient of the reproductibility is good. But the translation of this handicap scale, need a study of validity and reliability.
