Subclinical postural instability detected by stabiloplatform examination in the patients with vascular mild cognitive
Introduction:
Postural instability and balance dysfunction have been identified in the patients with dementia.
Aim:
The aim of our study was to evaluate subclinical postural and balance features in patients with vascular mild cognitive impairment (VaMCI).
Methods:
The study subjects were the patients with VaMCI (n = 62) and those without cognitive impairment (n = 35). Our cognitive performance examination consisted of the battery of tests including Luria memory words test, Shulte's tables, semantic and phonemic fluency test, the clock drawing test and Montreal cognitive assessment (MOCA). Postural function and balance control were assessed by computerized static ("Stabilan 01" Russia) and dynamic ("Gravistat", Belarus) stabiloplatforms using a biofeedback principle.
Results:
In the static stabiloplatform examination more pronounced postural instability in VaMCI patients was evidenced by larger gravity center displacement radius (p < 0.05) and confidence ellipse area (p < 0.05). In the dynamic stabiloplatform examination it was manifested by the reduced number of errors as attempts to maintain postural stability (p < 0.0001), a decrease in the error rate (p < 0.0001) and increase in the average time of a postural response as time spent for one error (p < 0.0001).
Conclusions:
Subclinical postural instability detected by the stabiloplatform examinations may be of value in earlier VaMCI diagnosis.
