Postural control test.
| Postural control test | ||
|---|---|---|
| Name | Situation | Sensory consequences |
| Conditions | ||
| Condition 1 (C1) | Eyes open on firm support | – |
| Condition 2 (C2) | Eyes closed on firm support | Vision absent |
| Condition 3 (C3) | Vision altered (virtual reality goggles), on firm support | Altered vision |
| Condition 4 (C4) | Eyes open on foam support | Altered proprioception |
| Condition 5 (C5) | Eyes closed on foam support | Vision absent, altered proprioception |
| Condition 6 (C6) | Vision altered (virtual reality goggles) on foam support | Altered vision and proprioception |
| Name | Pair | Significance |
| Ratios | ||
| Somatosensory (RSOM) | C2/C1 | Question: does sway increase when visual cues are removed? |
| Lower scores: better use of somatosensory references | ||
| Visual (RVIS) | C4/C1 | Question: does sway increase when somatosensory cues are inaccurate? |
| Lower scores: better use of visual references | ||
| Vestibular (RVEST) | C5/C1 | Question: does sway increase when visual cues are removed and somatosensory cues are inaccurate? |
| Lower scores: better use of vestibular cues | ||
Determination of the six conditions and significance of sensory ratios.
