Commentary: An Initial Passive Phase That Limits the Time to Recover and Emphasizes the Role of Proprioceptive Information

Commentary: An Initial Passive Phase That Limits the Time to Recover and Emphasizes the Role of Proprioceptive Information John H. J. Allum* and Flurin Honegger Division of Audiology and Neurootology, Department of ORL, University of Basel Hospital, Basel, Switzerland A Commentary on An Initial Passive Phase That Limits the Time to Recover and Emphasizes the Role of Proprioceptive Information by Le Goïc, M., Wang, D., Vidal, C., Chiarovano, E., Lecompte, J., Laporte, S., et al. (2018). Front. Neurol. 9:986. doi: 10.3389/fneur.2018.00986 A recent article by Le Goic et al. (1) raises the very same issues concerning the participation of vestibular-spinal reflexes in balance corrections to support surface movement that existed in the 90's—see Peterson, 1989 (2). Then, Nashner et al. assumed (3, 4), as have now Le Goic et al. (1), that the apparently delayed onset of head movement following a support surface translations of 35 cm/s or greater suggested little or no direct vestibular contribution to balance corrections. In order to establish a vestibular contribution, three conditions need to be fulfilled. Firstly, head angular and/or linear accelerations registered by the semi-circular canal and otolith sensory system, respectively, need to be early enough to contribute to balance corrections observed some 120 ms after the onset of the support surface perturbation (5–7). Secondly, the recorded head accelerations need to be su...
