Correlation analysis between HR in all directions and ICARS, SARA, and falls/year.

Parameter	ICARS (R, p)	SARA (R, p)	falls/year (R, p)
HR-AP	−0.35, 0.24	−0.35, 0.13	−0.10, 0.66
HR-ML	−0.47, 0.10	−0.36, 0.11	0.02, 0.92
HR-VT	−0.41, 0.88	−0.43, 0.06	−0.01, 0.99

The reported values represent Pearson correlation value (R) and statistical significance value (p). HR-AP: harmonic ratio in the anterior–posterior direction; HR-ML: harmonic ratio in the mediolateral direction; and HR-VT: harmonic ratio in the vertical direction.
