Postural control in underachieving students

This was a controlled cross-sectional study of a group of 51 underachieving students and a control group of 60 students with good school performance, with no history of vestibular disorders or neurotological complaints, volunteers from the community, age- and gender-matched. The students were submitted to Balance Rehabilitation Unit (BRU(tm)) posturography.

Results:

A total of 111 students aged 7 to 12 years old were evaluated. At posturography evaluation, there was no significant difference between the limit of stability area (cm²) of the control group and the experimental group. The comparison between groups demonstrated a statistically significant difference (p < 0.05) in the values of sway velocity (cm/s) and center of pressure area (cm²) in the ten sensory conditions evaluated.

Conclusion:

Posturography with virtual reality stimulation, allows for the identification of incapacity to maintain postural control, with or without visual deprivation, and the assessment of visual, somatosensory, and vestibular-visual interaction conflict in underachieving students.
