“…Additionally, stimulation of sensory information, i.e. prism adaptation, vestibular caloric stimulation, or galvanic vestibular stimulation, modifies the postural asymmetry of the subject, irrespective of the sensorial modality [9,18,23], with a close relationship between the effects of different sensory modalities [9]. This suggests that sensory stimulation affects supramodal sensorial cerebral structures in the right hemisphere [7], as already shown by Bottini et al [10].…”

“…Numerous studies had analysed GVS effects on postural control in healthy or pathological participants [ 6 , 41 – 47 ], or in relation with aging [ 48 – 50 ]. Nevertheless, to our knowledge, few studies have analysed GVS effects, in relation to physical activity status by focusing on postural control [ 31 , 51 ].…”

The purpose of this study was to compare the effects of galvanic vestibular stimulation (GVS) on postural control for participants of different physical activity status (i.e. active and non-active). Two groups of participants were recruited: one group of participants who regularly practised sports activities (active group, n = 17), and one group of participants who did not practise physical and/or sports activities (non-active group, n = 17). They were compared in a reference condition (i.e bipedal stance with eyes open) and four vestibular manipulation condition (i.e. GVS at 0.5 mA and 3 mA, in accordance with two designs) lasting 20 seconds. The centre of foot pressure displacement velocities were compared between the two groups. The main results indicate that the regular practice of sports activities counteracts postural control disruption caused by GVS. The active group demonstrated better postural control than the non-active group when subjected to higher vestibular manipulation. The active group may have developed their ability to reduce the influence of inaccurate vestibular signals. The active participants could identify the relevant sensory input, thought a better central integration, which enables them to switch faster between sensory inputs.

“…Several studies suggest that a rehabilitation program based on visual deprivation could promote the use of somatosensory and vestibular afferents and thus reduce visual dependence (de Haart et al 2004 ; Bonan et al 2004 ; Di Fabio and Badke 1991 ). In addition, in the aftermath of a stroke, sensory stimulation can be used to normalize postural control and reduce the extent of postural deficits, including visual stimulation (Tilikete et al 2001 ; Rode et al 2006 ; Bonan et al 2016 ), vestibular stimulation (Rode et al 1997, 2005), and somatosensory stimulation (Pérennou et al 1999 , 2001 ; Pérennou 2006 ).…”

Even for a stereotyped task, sensorimotor behavior is generally variable due to noise, redundancy, adaptability, learning or plasticity. The sources and significance of different kinds of behavioral variability have attracted considerable attention in recent years. However, the idea that part of this variability depends on unique individual strategies has been explored to a lesser extent. In particular, the notion of style recurs infrequently in the literature on sensorimotor behavior. In general use, style refers to a distinctive manner or custom of behaving oneself or of doing something, especially one that is typical of a person, group of people, place, context, or period. The application of the term to the domain of perceptual and motor phenomenology opens new perspectives on the nature of behavioral variability, perspectives that are complementary to those typically considered in the studies of sensorimotor variability. In particular, the concept of style may help toward the development of personalised physiology and medicine by providing markers of individual behaviour and response to different stimuli or treatments. Here, we cover some potential applications of the concept of perceptual-motor style to different areas of neuroscience, both in the healthy and the diseased. We prefer to be as general as possible in the types of applications we consider, even at the expense of running the risk of encompassing loosely related studies, given the relative novelty of the introduction of the term perceptual-motor style in neurosciences.
