Comparison of Postural Control Ability according to the Various Video Contents during Action Observations

ABSTRACT

Purpose@#This study examined the effects of the type of video contents used for action observations on the ability to control posture. @*Methods@#The participants were 48 healthy adults. The two hands of the participants were crossed on both shoulders, and the other foot was placed in a straight line in front of the target to allow them to watch a video of the monitor. The videos were presented in random order with three video contents (natural, stable balance posture, and unstable balance posture) consisting of 30 seconds each. A 15-second resting time was given between each video. During action observation using various video content forms, the posture control ability was measured using a TekScan MetScan® system. @*Results@#The results revealed statistically significant differences in the area of movement and the distance by COP and distance by the type of action-observation videos, and the distance by the anteroposterior and mediolateral sides (p<0.05). The stable balance posture and unstable balance posture video showed significant differences in the distance by the COP, anteroposterior, and mediolateral distance. (p<0.05) @*Conclusion@#This study suggests that choosing the contents of the videos is important during action-observation training, and action-observation training can help improve postural control.
