Abstract 210 children were enrolled in the study (130 in the control group, 80 in the study group), the propose of the study is to obtain normative data of the balance subset of BOT-2 in normal healthy children and to determine the sensitivity and specificity of such test to detect or exclude unilateral or bilateral peripheral vestibular dysfunction in children. Children in the control and study group were subjected to: History taking: including full medical (prenatal, perinatal and postnatal), audiological history and family history , Developmental history especially ,Otoscopic examination ,Audiological evaluation in the form of: (Immittancemetry and Conditioned play audiometry or conventional audiometry ), Caloric test /Vestibular-evoked myogenic potential testing was performed (only for the study groups) , Balance subtest of BOT-2 test Our results indicated that 71% of the control children were within the average category, 26 % were above average, and less than 1% (only one child) was well above average. 22% of children of group Ⅱ (SNHL children with normal vestibular function) were below average in the balance test. The rest of them were either within the average category (57%) or above average (21%). Most of children in group Ⅲ (SNHL with unilateral vestibular dysfunction) were either below average (80%), or well below average (10%). Only 10 % of the children within this group were within the average category. (37%) of children of group Ⅳ (SNHL with bilateral vestibular dysfunction) were below average, (44%) were well below average. The rest of children were within the average category. The sensitivity and specificity tests revealed that he most sensitive and specific test is the scale score ( 95.3% sensitivity, 92.3%s specificity), followed by item 9 (72.4% sensitivity, 92.3% specificity) then the total point score (77.2% sensitivity, 90.4% specificity), Criterion( < 11 ,< 2 ,< 31 respectively). The results of studies 10, 11, 54 were very comparable to ours. |
