From: Sub-sensory vibratory noise augments the physiologic complexity of postural control in older adults
Relationships between sub-sensory vibration-induced changes in postural sway complexity and mobility (i.e., timed up-and-go (TUG) test time) under 70 and 85 % vibration levels. Data from each of the three within-day testing sessions have been included (see Legend). Participants with greater percent increase of ML postural sway complexity improved mobility more (greater percent reduction of time to complete TUG) under both 70 and 85 % vibration levels (a and c). Within-day testing session did not significantly influence the strength of these correlations. No such associations were observed between changes in anterioposterior (AP) postural sway complexity and TUG performance (b and d)
