|---|---|---|---|---|
| X-SD | Y-SD | X-SampEn | Y-SampEn | |
| OLST | −0.227 | −0.162 | −0.049 | −0.354* |

Note:
*
Correlation is significant at the 0.05 level.
Abbreviations: SampEn, sample entropy; X-SD, standard deviation in the frontal plane; Y-SD, standard deviation in the sagittal plane; X-SampEn, sample entropy in the frontal plane; Y-SampEn, sample entropy in the sagittal plane; OLST, one-leg standing test; FR, functional reach; LR, lateral reach.
