摘要
Synchronized and coordinated activation of the postural muscles of the trunk and lower limbs is required for maintaining equilibrium and balance in human body. Poor postural balance control causes injury or falls in huge population and is supposed to be a critical factor of common motor skills. Single Leg Stance (SLS) is a good option for measuring postural control in any stance, which not only assesses postural steadiness in a static position by a temporal measurement (SLS-duration) but also analyses the role of body skeleton joints in postural stability and correction. This method provides a quick, reliable and easy way to screen their patients for fall risks and is easily incorporated into a comprehensive functional evaluation for older adults. An automatic unobtrusive system is proposed here to measure SLS duration and body balance. For this purpose, vibration-jitter analysis is performed which gives a clear view of relative variation of frequency of different skeleton joints over time. The whole processing is done on the dataset of skeleton joints obtained from Kinect. The dataset of skeleton joints through the Kinect setup, is used instead of video, which addresses user privacy concerns.
