FIG. 4.

Trunk orientation during walking posture assessment in experimental group (EXP) and control group (CON). (A) Root mean square (RMS) of displacement of trunk orientation in medial-lateral (ML) direction. (B) RMS velocity of trunk orientation in ML direction. Error bars represent standard error of the mean. *Represents significant group effect from analysis of covariance with pre-test set as covariate (p < 0.05). **Represents significant time effect from two-tailed paired t test (p < 0.017).
