The comparison of changes in PALs between the KVG-VR) and control groups.

	KBVRgroup (n = 28)	Control group (n = 28)	Treatment-by-time interaction
			Sig.	Partial η2
Pre	3.1 (2.6–3.2)	2.8 (2.4–3.1)	0.007*	0.13
Post	3.6 (3.2–3.8)	3.1 (2.5–3.2)
Sig.	<0.001*	0.47
Cohen's d	0.99	0.13

KBVR: Kinetic based virtual reality.

Data are expressed as median (interquartile ranges).

Sig: significance level, Partial η²: effect size for interaction effect, Cohen's d: effect size of the change within a group, * Significant at p < 0.05.
