The aim of the study was to determine balance parameters in a group of young patients with vertigo symptoms and to verify posturography helpfulness in clinical evaluation of vestibular system pathology.
77 children and adolescents of age 3-18 suffering from vertigo episodes participated in the study (46 girls, 31 boys). They underwent audiology objective tests and balance test on stable surface. Calculated balance parameters were analyzed in reference to: eyes opened and closed, age influence, sway comparison in anterior-posterior and medial-lateral, differences between subgroups with and without vestibular deficits. Discriminant analysis was performed to assess classification ability to impaired group in two cases: only balance parameters and both audiology and balance parameters.
Patients with vertigo symptoms generally keep their balance properly on stable surface. Balance parameters do not depend on presence of vestibular system pathology. Values increased in eyes closed conditions. Left/Right and Anterior/Posterior differences were not statistically significant. The negative correlation between age and some balance parameters is present, stronger in the case of eyes opened and weaker or absent in vestibular impaired group. Also, correlations between axes were found, higher in impaired group in comparison with not impaired one.
Discrimination based on balance parameters is poor not comparable to one built on combined: audiology and balance parameters, so typical balance parameters' analysis is not so useful in clinical practice when the reason of vertigo episodes should be assessed, but verify compensation process and measure with objective numbers the progress of recovering, the actual functional patient's status.
本研究的目的是确定一组有眩晕症状的年轻患者的平衡参数，并验证姿势描记法在前庭系统病理学临床评估中的有效性。
77名年龄在3至18岁之间患有眩晕发作的儿童和青少年参与了本研究（46名女孩，31名男孩）。他们接受了听力学客观测试以及在稳定表面上的平衡测试。计算得出的平衡参数参照以下因素进行分析：睁眼和闭眼、年龄影响、前后和内外侧的摆动比较、有和无前庭功能缺陷亚组之间的差异。进行判别分析以评估在两种情况下对受损组的分类能力：仅平衡参数以及听力学和平衡参数两者。
有眩晕症状的患者通常在稳定表面上能很好地保持平衡。平衡参数不取决于前庭系统病理学的存在。在闭眼条件下数值增加。左右和前后差异无统计学意义。年龄与一些平衡参数之间存在负相关，在睁眼情况下更强，在前庭受损组中较弱或不存在。此外，还发现了轴之间的相关性，受损组比未受损组更高。
基于平衡参数的判别能力较差，与基于听力学和平衡参数相结合的判别能力不可比，因此在评估眩晕发作原因时，典型的平衡参数分析在临床实践中不太有用，但可验证代偿过程并用客观数字衡量恢复进展、患者的实际功能状态。
