Scope: The aim of this study is to compare odor performance of sensorial disabled individuals (deaf and blind) with healthy individuals.
Method: 41 deaf students (22 female, mean age 14.39±1.24), 40 blind students (17 female, mean age 13.55±1.43) and 52 healthy (24 female, mean age 13.48±1.09) students participated in this study.
The odor threshold, odor discrimination and odor identification performances were measured through Sniffin’ Sticks. Obtained data was evaluated by SPSS 11.0.1 and one-way ANOVA was used for statistical analysis.
Results: Post hoc Scheffe test showed for threshold there were no significant differences between groups (deaf students: 7.40±3.47, blind students: 8.45±3.35, healthy students: 8.00±2.73), for discrimination, healthy students (12.32±1.81) had significantly better performance than deaf students (10.87± 2.29) (p < .05). For identification, both blind students (11.45±1.99) and healthy students (11.96±1.48) had significantly higher points than deaf students (9.87±2.01). On the contrary there was no difference between blind and healthy students. Total points (TDI) displayed similar to results of identification (blind 31.65 ±5.09, deaf 28.15 ±5.56, healthy 32.30 ±3.86).
Conclusion: This initial field study in the sensory disabled can be used as a template for assessing and designing behavioral as well as objective (i.e. CERP) research studies.
