POSTURAL RESPONSES EVOKED BY HEAD MOVEMENTS AND ALTERED SOMATOSENSORY INFORMATION

Inga  Liepiņa; Aivars Kaupuzs

Abstract

Background. Balance is one of the most important skills of the postural control and ability to move. The data of many studies have shown that postural sway was reduced while participants perform a balance task concurrently with a cognitive task. There are some evidences that postural sway decreases under threatening conditions. The aim of this study was to examine the immediate postural responses evoked by head movements standing on foam surface. Methods. The study subjects were 32 first year students.
Participants ranged in ages from 18 to 20 years old (Mean – 19.5; SD – 1.07).The Sway Index (SI) was measured by Biodex Portable Balance System – BioSway. Results. Performing of head movements left to right 20 seconds with 3 repetitions with closed eyes evoked decreased postural sway in 18 participants
(SI – p = .001; medial/lateral – p = .004, anterior/posterior – p = 0.092). Conclusion. This study provides evidence that specific changes in somatosensory environment could be related to changes in static
postural control.
