Fig. 4: Correlations between Halo Movement scores and functional movement tests.
From: Validation of Amazon Halo Movement: a smartphone camera-based assessment of movement health
When comparing normally distributed variables, correlations were measured using Pearson’s product-moment coefficient. For non-normally distributed variables, correlations were measured using the Spearman’s rank correlation coefficient. Correlations that were not statistically significant are grayed out. Hypothesis for sign of correlation between Halo Movement and functional test to support validity – Positive correlation: RBBs, CKCUE, Y-balance, sit and reach, Star excursion, Hurdle Step, UHBE, Single Leg Hop, CTSIB(t), Sharpened Romberg (t); Negative correlation: Plumb line, RBBi, CTSIB(acc), Sharpened Romberg (acc).
