“…89,93,95,103 Analogous behavior is also observed in humanoid robots, where impairments to visual (camera) and vestibular (gyroscope) inputs trigger sensory reweighting of the postural control system that results in higher amplitude, lower frequency balance responses and increased fall risks. 110 Contributions of head motion to postural sway have been studied in less detail but have been shown to be significant even in healthy individuals. 27,[111][112][113][114] The head serves as an egocentric reference for balance, walking, and most other voluntary motor activities, 115 and centralizes the integrated sensing of physiological signals.…”
