Table 2.

Mean (SD) of the Hip, Knee, and Ankle Joint Kinematic Measures During the Landing Phase of a Jump-Landing Task in Both the Standard (ie, DVJ) and VR (ie, Header Task in the Soccer Corner-Kick Scenario) Conditions

Kinematic measure	Standard	VR	Adj P
Hip flexion at peak knee flexion, deg	37.4 (19.5)	25.2 (15.7)	.04*
Hip abduction at peak knee flexion, deg	−2.9 (4.8)	0.5 (5.6)	.02*
Peak knee flexion, deg	−67.0 (14.5)	−63.7 (13.3)	> .99
Peak knee abduction, deg	−6.4 (3.9)	−7.0 (6.3)	> .99
Ankle dorsiflexion at peak knee flexion, deg	25.6 (5.4)	12.6 (10.3)	<.001*
Ankle inversion at initial contact, deg	4.9 (3.7)	1.7 (5.7)	.01*

Abbreviations: DVJ, drop vertical jump; VR, virtual reality.
