Siegmund, G.P. Schouten, A.C. Blouin, J.S. Faculty Mechanical, Maritime and Materials Engineering Department Biomechanical Engineering Date 2015-01-09 Abstract The vestibular system is crucial for postural control; however there are considerable differences in the task dependence and frequency response of vestibular reflexes in appendicular and axial muscles. For example, vestibular reflexes are only evoked in appendicular muscles when vestibular information is relevant to postural control, while in neck muscles they are maintained regardless of the requirement to maintain head on trunk balance. Recent investigations have also shown that the bandwidth of vestibular input on neck muscles is much broader than appendicular muscles (up to a factor of 3). This result challenges the notion that vestibular reflexes only contribute to postural control across the behavioral and physiological frequency range of the vestibular organ (i.e., 0–20 Hz). In this review, we explore and integrate these task-, muscle- and frequency-related differences in the vestibular system’s contribution to posture, and propose that the human nervous system has adapted vestibular signals to match the mechanical properties of the system that each group of muscles controls Subject vestibular reflexespostural controltask dependentfrequency responseappendicular musclesaxial muscles To reference this document use: http://resolver.tudelft.nl/uuid:accc68b7-0c5f-46ce-98ea-2b9efdbf1339 DOI https://doi.org/10.3389/fnint.2014.00094 ISSN 1662-5145 Source http://journal.frontiersin.org/article/10.3389/fnint.2014.00094/abstract Source Frontiers in Integrative Neuroscience, 8, 2015 Part of collection Institutional Repository Document type journal article Rights (c) 2015 The Author(s) Files PDF 314817.pdf 1023.56 KB Close viewer /islandora/object/uuid:accc68b7-0c5f-46ce-98ea-2b9efdbf1339/datastream/OBJ/view
