Figure 4.

Modulation of stance and gait behavior induced by different postural tasks. Figure 4 presents a schema summarizing the effects of the factors “height situation” and “postural condition” on the stance performance (A) and gait performance (B) of subjects susceptible to vHI. Light gray sector—condition effect for “height condition” (balcony compared to laboratory). Dark gray sector—condition effect for “postural condition” (Dual Task (DT) or Eye Closure (EC) compared to Single Task). indicates significant deterioration of stance/gait performance. indicates an improved stance/gait performance. ↔ indicates no significant differences.
