Variation of computerized dynamic posturography values according to body mass indexes, gender and age groups

The balance system is a complex mechanism that includes many biomechanical processes. The Computerized Dynamic Posturography (BDP) device is a gold standard test that evaluates the balance of the body and is widely used in clinics today. BDP is applied for individuals of all ages, genders, heights and weights. Since the number of clinical studies conducted with BDP in our country is low, our research will also contribute to the normative data.The aim of this study is to examine the effect of age, gender and body mass index on balance and to investigate whether it has an effect on Computerized Dynamic Posturography used in the evaluation of balance system.The study was carried out in the Audiology Clinic of Private Acıbadem Kozyatağı Hospital, and it was carried out with 70 healthy volunteers between the ages of 20-60 with out ear and vestibular system complaints. The SPSS 28.0 program wasused in the analysis of the data, and the balances- cores of the patients were given as the mean and standardt able with the variables. Chi-Square test (ChiSquare test) was used to determine the relation ship between age, gender, body mass index groups and balance parameters. The "p" value indicates a statistically significant difference in a comparison and takes a value between 0 and 1 in the Chi-Square istatistic. The closer the value is to 1, the stronger the relationship. If the "p" value is between 0.01 and 0.05, there is a significant difference. When the balance scores of men and women were compared, no significant difference was found.According to age; SOM/AP, VIS/AP, PREF/AP values did not differ signifi- cantly (p>0.05) VEST/AP and GLOB/AP values were significantly (p<0.05) lower in the age ≥ 38 group than in the age ≤37 group. SOM/ML and PREF/ML values did not differ significantly (p>0.05) between groups aged≤37 years and ≥38 years. The VIS/ML, VEST/ML and GLOB/ML values in the age≥38 group were significantly (p<0.05) lower than the age≤37 group. SOM/AP, VIS/AP, PREF/AP, VEST/AP, GLOB/AP values did not differ significantly (p>0.05) between groups with BMI<25 and BMI≥25 in balance scores evaluated according to body mass index. SOM/ML, VEST/ML and GLOB/ML values did not differ significantly (p>0.05) between gro- ups with BMI<25 and BMI≥25. In the group with BMI<25, the VIS/ML value was significantly (p<0.05) lower than the group with BMI≥25. The PREF/ML value in the group with BMI<25 was significantly (p<0.05) lower than the group with BMI≥25. As a result of the general correlation analysis of all participant data in our study; Global and Vestibular balance scores were found to decrease with increasing age.
