Postural Sway High Impact Factor Journals

Postural sway, in terms of human sense of balance, refers to horizontal movement round the center of gravity. This sway is important thanks to the various large and little changes within the center of gravity thanks to functions like walking and breathing. For a person to maintain balance requires coordination of input from multiple sensory systems including the vestibular, somatosensory, and visual systems. The vestibular sense controls equilibrium and directional information as it relates to head position and is related to middle ear. The somesthesia senses information from skin and joints (pressure and vibratory senses) along a side spatial position, movement relative to the support surface, and movement/position of various body parts relative to each other. The visual system works by reference to the verticality of body and head motion and spatial location relative to objects. These systems together coordinate to permit us to take care of balance: the more balanced the less postural sway. Asymmetrical posture and weight bearing are the most common post-stroke symptoms, causing an increase in postural sway. The increase in postural sway during standing is due to the degeneration of the nervous system and is more severe in elderly people than young adults.
