Technology-Assisted Balance Control: The Application Of Real-Time Visual Feedback System Of The Centre Of Pressure With Smart Wearable Devices

Background: The body maintains stability by integrating inputs from the central nervous system of vision,hearing,proprioception,and multiple senses.With the development of smart wearable devices,smart wearable devices can provide real-time center of pressure(COP)position-assisted balance control,which is beneficial to maintain physical balance.Purpose:(1)Whether providing real-time visual feedback information in the pressure center with intelligent insoles can improve the control ability during static standing.(2)To explore whether there are gender differences in the use of wisdom insoles to provide visual feedback.Methods: Forty healthy college students(20 male-20 female)participated in this study,and the posture balance actions of left-leg stance non-visual feedback,left-leg stance visual feedback,right-leg stance non-visual feedback,and right-leg stance visual feedback are performed.Visual feedback provides smart insoles matching Podoon APP on a tablet computer with the COP position displayed by a dot as real-time visual feedback.Results: The experimental results show that the displacement,velocity,radius,and area of the COP decreased significantly in the left-leg stance visual feedback/right-leg stance visual feedback,the test compared with the parameters in the eft-leg stance non-visual feedback/right-leg stance non-visual feedback(P < 0.05).In the one leg visual/non-visual in standing,the COP maximum anteroposterior displacement,COP anteroposterior velocity,COP radius,and COP area of women are significantly decreased than men(P <0.05).Conclusion: The simple intelligent wearable assisted devices can immediately increase the control ability in static stance of men and women,and women have better real-time balance control ability than men.
