PURPOSE: To evaluate by foam-laser dynamic posturography (FLP), the integration between the vestibular, visual, and somatosensory systems through the sensory organization test (SOT) and to compare the results obtained in adults and elderly individuals with dizziness. CASE REPORT: Thirty-five individuals with a complaint of dizziness were evaluated. They consisted of 22 (63%) adults (18 [82%] women and 4 [18%] men) and 13 (37%) elderly individuals (11 [85%] women and 2 [15%] men). The mean age was 44.85 years (for women) and 70.70 years (for men). We found a prevalence of rotatory dizziness in adults (66.64%) and non-rotatory dizziness in elderly individuals (61.54%), which showed an inverse proportional relationship. In the FLP analysis, we found in the adults the involvement of TOS I (66.64%); TOS III (68.18% with 13.64% falls); TOS V (63.64% with 13.64% falls) and TOS VI (54.55% with 13.64% falls). In elderly individuals, in position I (61.54%); position II (72.92%); position III (61.54%); position V (69.23% with 15.38% falls) and position VI (61.54% with 23.08% falls). CONCLUSION: In this study, we found a larger number of women with a complaint of dizziness. The most frequent type of dizziness was rotatory dizziness in adults and nonrotatory dizziness in elderly individuals. We also found that the analysis of the FLP of all participants showed alterations, indicating difficulties in the systems responsible for balance.
