Table 1 Acceleration similarity between sensors (AAC). The mean acceleration similarity and category between each sensor are shown for each condition. AAC: average acceleration correlation, VS: very strong, S: strong, M: moderate, W: weak, SD: standard deviation, EO: eye-opening condition, EC: eye-closing condition.

From: Control of structural redundancy from the head to trunk in the human upright standing revealed using a data-driven approach
