“…The importance of context may be analogous for auditory stimuli. While limited research exists on the relationship between auditory input and postural control, a few studies incorporated natural sounds (e.g., a fountain) and suggested that differences in response to natural sounds relate to the properties of the sounds (greater variety of binaural and monaural cues including static and moving features) ( 9 ) and the innate emotional/cognitive responses of the individual ( 5 ). The majority of studies, reporting that balance is context-dependent, however, refer to the task (single or dual, static or dynamic) or the surface type ( 10 – 13 ).…”

Virtual reality allows for testing of multisensory integration for balance using portable Head Mounted Displays (HMDs). HMDs provide head kinematics data while showing a moving scene when participants are not. Are HMDs useful to investigate postural control? We used an HMD to investigate postural sway and head kinematics changes in response to auditory and visual perturbations and whether this response varies by context. We tested 25 healthy adults, and a small sample of people with diverse monaural hearing (n = 7), or unilateral vestibular dysfunction (n = 7). Participants stood naturally on a stable force-plate and looked at 2 environments via the Oculus Rift (abstract “stars;” busy “street”) with 3 visual and auditory levels (static, “low,” “high”). We quantified medio-lateral (ML) and anterior-posterior (AP) postural sway path from the center-of-pressure data and ML, AP, pitch, yaw and roll head path from the headset. We found no difference between the different combinations of “low” and “high” visuals and sounds. We then combined all perturbations data into “dynamic” and compared it to the static level. The increase in path between “static” and “dynamic” was significantly larger in the city environment for: Postural sway ML, Head ML, AP, pitch and roll. The majority of the vestibular group moved more than controls, particularly around the head, when the scenes, especially the city, were dynamic. Several patients with monaural hearing performed similar to controls whereas others, particularly older participants, performed worse. In conclusion, responses to sensory perturbations are magnified around the head. Significant differences in performance between environments support the importance of context in sensory integration. Future studies should further investigate the sensitivity of head kinematics to diagnose vestibular disorders and the implications of aging with hearing loss to postural control. Balance assessment and rehabilitation should be conducted in different environmental contexts.

“…The amount of body sway also reflects the postural control in a quiet stance. A static sound cue was found to decrease the amount of body sway in stance (Gandemer et al, 2017). A rotating sound cue was found to decrease the amount of body sway in stance (Gandemer et al, 2014).…”

Under certain conditions, a tactile stimulus to the head induces the movement of the head away from the stimulus, and this is thought to be caused by a defense mechanism. In this study, we tested our hypothesis that predicting the stimulus site of the head in a quiet stance activates the defense mechanism, causing a body to sway to keep the head away from the stimulus. Fourteen healthy male participants aged 31.2 ± 6.8 years participated in this study. A visual cue predicting the forthcoming stimulus site (forehead, left side of the head, right side of the head, or back of the head) was given. Four seconds after this cue, an auditory or electrical tactile stimulus was given at the site predicted by the cue. The cue predicting the tactile stimulus site of the head did not induce a body sway. The cue predicting the auditory stimulus to the back of the head induced a forward body sway, and the cue predicting the stimulus to the forehead induced a backward body sway. The cue predicting the auditory stimulus to the left side of the head induced a rightward body sway, and the cue predicting the stimulus to the right side of the head induced a leftward body sway. These findings support our hypothesis that predicting the auditory stimulus site of the head induces a body sway in a quiet stance to keep the head away from the stimulus. The right gastrocnemius muscle contributes to the control of the body sway in the anterior–posterior axis related to this defense mechanism.

“…Sounds moving along a 180-degree arc were found to increase sway (compared with silence) in 1 study but to reduce sway (compared with blocking sounds) in another study . Other studies reported reduction, no change, or increase in postural sway with rotating sounds . Guigou et al postulated that, in monaural hearing, the rotation of the sound was not perceived, and thus sound had a stabilizing role like a stationary sound.…”
